Basis, Sources, and Limitations

Part I

Scope, status and reservations

What this dashboard is, what it is not, and the terms on which its contents are offered.

¶ 1

Purpose. This note sets out, for each exhibit published on Bailiwick & Ballot, the sources on which it rests, the manner in which it was constructed from those sources, the reconciliations performed against independent records, and the qualifications subject to which it should be read. It is intended to permit a reader to trace any figure appearing on the dashboard to the record from which it was taken, and to assess for himself the weight that figure will bear.

¶ 2

Nature of the work. The dashboard is independent research and analysis prepared by the author in his personal capacity. It was not commissioned by, prepared for, or undertaken at the instance of the Commission on Elections, of any party-list organization, or of any other person or body. It is not an official government record or publication, and no part of it has been adopted, reviewed, verified or endorsed by the Commission on Elections or by any other government agency.

¶ 3

Reservation as to legal advice. Nothing in this dashboard, in this note, or in any exhibit or table published with them constitutes legal advice, and nothing in them is to be construed as legal advice or as the rendering of a legal opinion upon the affairs of any person or organization. Statements of law appearing in Part II are included to disclose the framework against which the registration and delisting exhibits were constructed, and for that purpose only. No lawyer-client relationship arises from the publication of, or from reliance upon, any part of this work. A reader whose interests may be affected by the matters discussed here should take his own advice upon his own facts.

¶ 4

Status: not peer-reviewed. This work has not undergone peer review. It has not been submitted to, accepted by, or published in any scholarly or professional journal, and it is not offered for such publication. It has not been refereed, editorially reviewed, or independently replicated by any third party. Where this note adopts the conventions of scholarly reporting — a register of sources, numbered references, a statement of limitations — it does so because those conventions make the basis of the work legible and its defects locatable, and not in order to suggest that the work carries the warrant that peer review confers. The reader is accordingly asked to treat every finding here as the author’s own, resting on the sources disclosed in Part III and subject without exception to the limitations stated in Part V.

¶ 5

Currency and revision. The dashboard states a position as at the date shown in the masthead. The great majority of the materials on which it rests are publicly available documents and datasets held by third parties, principally the Commission on Elections. Such materials are liable to be amended, superseded, re-tabulated, withdrawn from publication or decommissioned without notice, and several relied upon here have already suffered one or more of those fates during the currency of this project. A figure correct against the record as it stood on the date of collection may therefore cease to correspond to the record as it stands when read. Dates of collection are given for every source in Part III for that reason, and the limitation is developed at Part V(B).

Part II

Legal framework

The statutory and jurisprudential framework against which the registration and delisting exhibits are constructed, disclosed so that the reader may test the construction. Subject throughout to the reservation at ¶ 3.

¶ 6

Governing statute. The party-list system is governed by Republic Act No. 7941, the Party-List System Act.[1] Registration of a party-list group, and the cancellation of that registration, are matters committed by the Act to the Commission on Elections.

¶ 7

Grounds relied upon. Section 6 of the Act enumerates the grounds upon which the Commission may, motu proprio or upon verified complaint of any interested party, and after due notice and hearing, refuse or cancel a registration. Two of those grounds are material to the exhibits on the Registration tab:

Section 6(8) — “It fails to participate in the last two (2) preceding elections or fails to obtain at least two per centum (2%) of the votes cast under the party-list system in the two (2) preceding elections for the constituency in which it has registered.”

A third ground is material to the treatment of a single group on the Election tab:

Section 6(5) — “It violates or fails to comply with laws, rules or regulations relating to elections;”

¶ 8

Construction of section 6(8). Section 6(8) states two grounds, not one. In Philippine Guardians Brotherhood, Inc. v. Commission on Elections[2] the Supreme Court, En Banc, read the word “or” in the provision as disjunctive and held that “[t]he plain, clear and unmistakable language of the law provides for two (2) separate reasons for delisting”, so that “[a] delisting based on a mixture or fusion of these two different and separate grounds for delisting is therefore a strained application of the law.” The Court abandoned Minero, which had treated a group that did not participate as having, by default, obtained less than two per centum. This dashboard reads the provision accordingly: a group that participates but polls below the threshold does not thereby fail to participate; a group that sits out an election has no vote in it to be measured; and the two counts are never added together anywhere on this dashboard.

¶ 9

Consequence for the exhibits. The 21 card, the 38 card and the Comeback groups for 2028 cohort on the Registration tab are each constructed upon the reading at ¶ 8, applied to the ballot population disclosed at Part IV(F). Each card accordingly identifies groups whose electoral record, on the published returns, answers the description in one limb of section 6(8). It does not follow, and is nowhere asserted, that any group so identified stands delisted, is the subject of any proceeding, or will be acted upon. Cancellation is an act of the Commission; the cards record exposure on the face of the returns, and nothing more. The point is stated on the cards themselves and is repeated at Part V(G).

¶ 10

The published orders. The Commission’s exercise of the power is recorded on this dashboard through three published delisting resolutions, transcribed in full and segmented by the ground each cancellation was laid upon: Resolution No. 10273 of 19 March 2018,[3] Resolution No. 10696 of 17 February 2021,[4] and Resolution No. 11071 of 1 October 2024.[5] The grounds shown in the Delisting Resolutions exhibit are the orders’ own characterizations, not this project’s. One cancellation in the 2018 order rests on a footing of its own and is carried separately as a special ground.

¶ 11

The 2028 registration deadline. Section 6 of Resolution No. 11204[6] fixes 18 December 2026, within regular working hours, as the last day on which a petition for registration as a party-list organization intending to contest the 2028 elections may be filed. The countdown card on the Registration tab is computed against that date in Philippine standard time.

¶ 12

An Waray. The treatment of An Waray in the 2022 exhibits follows An Waray Party-List v. Commission on Elections,[7] in which the Court dismissed the petition for certiorari and affirmed the Second Division’s resolution of 2 June 2023 and the En Banc’s resolution of 14 August 2023 in SPP No. 19-008. The ground was section 6(5), and the violation dated from the 2013 term. An Waray won a seat in 2022 and was unseated after the election by cancellation of its registration; it is plotted on this dashboard as a group that won and was later unseated, and not as a group that missed. The same convention is applied to Duterte Youth in 2025.

¶ 13

Reservation. Parts II and IV disclose a reading of the Act and of the authorities cited. That reading is the author’s. It is not a determination, and it is not offered as one. The Commission on Elections determines registration and cancellation, and its determination controls. Where this note states that a group is within the description of a ground, it states a conclusion about the published returns; it states nothing about the outcome of any proceeding, whether pending or prospective.

Part III

Register of sources

Every source on which an exhibit depends, what it supplies, how it was collected, when, and what is known to be wrong with it. Sources are cited in Part IV by the key in the first column, and in full in Part VI.

Part IV

Construction of the exhibits

Each exhibit on both tabs, set out under four heads — the sources it draws on, how it is built from them, what it has been reconciled against, and the qualifications it carries. Source keys are those of Part III. Text carried over from the dashboard’s own captions is reproduced without alteration.

A · Concentration against the seat line — Election tab

IV.A

Common construction of the four charts

Election
Construction
Every group on that year’s ballot is plotted. Horizontal position is the share of a group’s national vote drawn from its single largest region. Vertical position is its total national vote, on a logarithmic scale. The dashed rule is that year’s seat line — the vote of the last group to take a seat. The four charts share axes and construction, so they are directly comparable.
Populations
115 groups in 2016, 134 in 2019, 177 in 2022, 155 in 2025. Seats won: 46, 51, 56 and 57 respectively, the last two counted on the post-cancellation roster (¶ 12).
Caveats
Overseas and local absentee votes count in each group’s national total but have no region, so they lower a concentration rather than raise it.
IV.A.1

Concentration against the seat line, 2016

Election
Sources
Vote totals: the official COMELEC canvass. Regional shares: S15 municipality-level returns collected by the OpenHalalan project from the GMA election feed.
Construction
Every group on the ballot is plotted. The seat line is Agbiag! Timpuyog Ilocano on 240,723 votes, the last of 59 seats.
Reconciliation
The OpenHalalan pipeline is controlled through its 2022 layer, whose national total reproduces this project’s independent canvass walk to the vote (S17, S1). The 2016 feed falls 3.12% short of the official national total and is scaled to it by largest-remainder rounding, so province tables sum to the official figure exactly.
Caveats
COMELEC’s own 2016 results site no longer exists, so the sub-national layer is broadcaster-sourced and not official. Sulu and Lanao del Sur are under-reported in that feed, so Sulu-based groups such as Kusug Tausug sit slightly low. Province shares are reliable; individual small-province figures should be treated as approximate.
IV.A.2

Concentration against the seat line, 2019

Election
Sources
Vote totals: the official COMELEC canvass, and for the national figures the Party-List Canvass Report S3. Regional shares: S16 municipality-level returns collected by the OpenHalalan project from the ABS-CBN election feed.
Construction
Every group on the ballot is plotted. The seat line is Kabataan on 195,837 votes — the cheapest seat in the series, and 0.70% of the vote the seats were allocated on.
Reconciliation
Spot-checked against S3 and agreeing to the vote: ACT-CIS 2,651,987, Bayan Muna 1,117,403, Ako Bicol 1,049,040, and Kabataan’s 195,837 seat line. The feed falls 1.53% short of the official national total and is scaled as at IV.A.1.
Caveats
COMELEC’s 2019 results site has been decommissioned and was never archived; the canvass report S3 survives on the corporate site and is the national basis. The same Sulu and Lanao del Sur caveat applies. 2019 is the worst year in the series for non-electing ballots by a wide margin and must not be read as a point on a trend line.
IV.A.3

Concentration against the seat line, 2022

Election
Sources
S1 COMELEC’s own 2022 canvass, walked across all 1,659 municipal canvass boards on the official results API and re-collected for this page on 12 September 2026. The broadcaster feed does not appear on this chart.
Construction
Vertical position is the published total for all 56 winners and the canvass total for every other group. Horizontal position is each group’s share of its own canvassed vote from its largest region, from the same walk. The seat line is Akbayan’s published 236,226. OFW Family and WOW Pilipinas, which earlier versions could not plot for want of sub-national returns, are on the chart.
Reconciliation
The walk’s per-group totals sum to exactly the published 36,656,659 valid votes, and the board-level identity obtained + blank + overvoted = voters who actually voted holds on every one of the 1,659 boards. Against S18, Rappler’s 2022 bailiwick analysis, the same groups reproduce to within rounding: Uswag Ilonggo 96.4 against 96, Alona 96.9 against 97, Tingog 46.9 against 47, Abono 89.4 against 89, API 94.6 against 95.
Caveats
An Waray is marked separately. It polled 384,968 — 1.63 times the seat line, 82.5% of it from Eastern Visayas — and won a seat in 2022. Its registration was cancelled in 2023 over a violation dating to 2013, upheld by the Supreme Court in S13, and the seat passed to Akbayan, proclaimed 25 September 2024. It is plotted as a group that won and was later unseated rather than as a miss, and the 56 groups counted as winners are the post-cancellation roster (¶ 12).

Two winners’ published totals differ from their canvass sum by more than 1% — TUCP by 25,776 votes and Patrol by 4,138. These are per-group differences between COMELEC’s published canvass report and the board walk which this project has not attributed to any unit. Those two groups carry the published figure vertically and their own canvassed share horizontally, so neither axis mixes tables.

COMELEC’s 2022 per-board results have refused access since 13 September 2026, so no province-level group figure for 2022 can now be obtained from COMELEC. The walk of 12 September is the only copy.
IV.A.4

Concentration against the seat line, 2025

Election
Sources
S2 published national canvass for the 57 seat-winners; the reconciled precinct file for every other group (92,822 clustered-precinct rows, 155 groups, 20 regions). S6 for the earlier seat line; S11 and S12 for the two cancellations.
Construction
Vertical position is the published total for the 57 winners and the precinct-level total for everyone else. Horizontal position is the group’s share of its own vote from its single largest region. Overseas absentee votes are included, as they are in the published totals: 199,230 votes nationally. The chart carries two seat lines because the 2025 allocation was made twice.
Reconciliation
Measured against the 57 published winner totals the precinct file is never high — median 0.128% low, worst 7.00% low (Kusug Tausug), then 5.38% (Trabaho) and 5.00% (Kapuso PM). Every non-winner on this chart is therefore a floor, and every shortfall computed from it is a maximum.
Caveats
Duterte Youth is marked separately. It polled 2,338,564 — the published canvass total, and the single exception to the rule above, being the only group carrying a published figure that is not one of the 57 winners — and would have been the second-largest group on the ballot. The En Banc cancelled its registration on 29 August 2025, after the election, and its three seats passed to Abono, Murang Kuryente and Ang Probinsyano. Its votes are marks on ballots but are not part of the base on which the seats were finally allocated.

The two lines. COMELEC’s allocation of 16 May 2025, with Duterte Youth in it at rank 2 on three seats, put the last seat at Philreca on 261,045. The line in force since the cancellation is Murang Kuryente’s 247,754, and that is the line every ×-the-line figure on this dashboard uses. The upper rule and the shaded range between them are the earlier allocation, transcribed from that computation and not recomputed here; the difference is 13,291 votes, about 5%.

The allocation was made on two bases. One sheet includes Pilipinas Babangon Muli and one excludes it, the Second Division having cancelled PBBM’s registration on 23 April 2025 — three weeks before the election — for presenting itself as a Calabarzon regional party when eight of its ten nominees and all its top officers are from Abra. PBBM appealed to the Supreme Court and that case is pending, so the cancellation is not final and the line shown is from the sheet that includes it. On the other sheet the last seat is Swerte on 261,379 rather than Philreca on 261,045.

B · Vote heatmap — Election tab

IV.B

Vote Heatmap

Election
Sources
Geometry S20. Registered voters and turnout S5. Party-list votes by province: S15 2016, S16 2019, S17 2022 province shading and regional top-threes, S1 2022 national and regional group figures, S2 2025. Blank ballots 2022 from an independent re-walk of S1; 2025 from S2.
Coverage
84 provinces are mapped for 2016, 2019 and 2022, and 86 for 2025. Maguindanao was a single province in the first three elections and split in two after the 2022 vote, so the two shapes the map uses carry data only from 2025. The City of Isabela votes with Basilan and never appears separately in the returns, so its outline is drawn as part of Basilan’s.
Construction
Group votes are shown where a group took at least 500 votes in a province, which retains about 97% of each year’s vote; the province total used for shares is the full figure, so percentages are not inflated by the cut-off. The summary view adds each region’s map units together for every figure it shows, so a region’s turnout and its blank votes describe the same places. Each region’s top three is summed from the 500-vote province figures; where a top-three group fell under 500 in any of the region’s provinces its share is marked “at least”. Shading for a group runs on linear bins from zero to that group’s highest province, so a province holding a small fraction of a group’s peak reads pale rather than dark; the blank-ballot, turnout, registered-voter and party-list-vote layers use quantile bins, and the summary view shades each province by its whole region’s party-list vote.
Reconciliation
The 2022 province shading and regional top-threes, drawn from S17, agree with the COMELEC canvass S1: every region’s party-list total to the vote except BARMM, which lacks Maguindanao, and all 509 of the canvass’s group-by-region figures outside BARMM either equal it or fall within the 500-vote cut-off. Municipality tables reproduce each year’s province totals exactly. The 2022 blank-ballot re-walk reproduces the published national totals exactly — 55,915,062 ballots cast, 17,486,021 blank, 1,772,382 overvoted, 36,656,659 obtained — and the identity obtained + blank + overvoted = voters who actually voted holds on every one of the 1,659 boards. Province totals for 2025 are the precinct file’s own sums, 41,419,622 nationally against the published 41,950,292, the difference being overseas and local absentee voting, which has no province.
Caveats
The 2022 group layer sits on two bases. COMELEC’s 2022 per-board results have refused access since 13 September 2026, so no province-level group figure for 2022 can come from COMELEC any more. Its official canvass, walked before that date, still gives every group’s national total and its three strongest regions; the province shading and each region’s top three come from S17.

Blank votes exist for 2022 and 2025 only. COMELEC never published them below the national level for 2016 or 2019 and those results sites have been decommissioned; none exists to recover. For 2022 the ten municipalities with the most blank ballots are carried in each province; 2025 carries every municipality.

Registered voters and turnout are the domestic automated canvass and leave out overseas voting, so they are never compared with a national ballots-cast figure. For 2016 Metro Manila was published only as one region, so its four districts show no data that year.

Sulu and Lanao del Sur are hatched in 2016 and 2019: both had failures of election and disrupted canvassing in those years, and Sulu’s party-list vote nearly doubled by 2022.

Boundary conventions. Before 2025 BARMM leaves out Maguindanao; in 2025 the Special Geographic Area counts in Region XII with Cotabato rather than in BARMM. Overseas and local absentee voting have no geography and are excluded from the map while still counting in every national total.

A corrected basis. An earlier version of this page carried 2025 province totals from a different aggregation, and for three BARMM provinces those totals exceeded the number of voters who did not leave the party-list section blank — Lanao del Sur by 95,005 votes. They are now on one basis with everything else the map shows.

C · The seat line over time — Election tab

IV.C.1

What one seat costs, as a share of the vote

Election
Sources
S1, S2, S3 for the four seat lines and the bases they were allocated on; S6 for the 2025 pre-cancellation allocation.
Construction
Each point is the last group to win a seat that year, expressed as a percentage of the votes the seats were allocated on. The figure under each point is that group’s actual vote total. The series is 240,723 (0.743%), 195,837 (0.702%), 236,226 (0.644%) and 247,754 (0.625%).
Caveats
2025 carries a second, paler dot: the allocation of 16 May 2025 put the last seat at Philreca on 261,045, which is 0.622% of the vote cast against 0.625% after. The 2022 seat line is Akbayan’s published 236,226, not the canvass figure of 235,312; that choice is recorded once and is not reopened.

Ballots cast: 44,980,362 / 47,296,442 / 55,915,062 / 57,350,970. Valid party-list votes: 32,377,841 / 27,884,790 / 36,656,659 / 41,950,292.

Registered voters from S5 are the domestic automated canvass; voters who actually voted in those tables is not ballots cast and the two are never cross-compared or used to recompute a national rate. 2025 has eighteen regions and 83 provinces, Negros Island Region having been carved out of Regions VI and VII, so any join on a fixed region list will mis-assign it.
IV.C.3

Non-electing ballots

Election
Sources
series_2016_2025.csv, derived from S1S3; winners’ published totals for the non-winning band.
Construction
Two segments per year. The first is ballots cast less valid party-list votes — 12,602,521 in 2016, 19,411,652 in 2019, 19,258,403 in 2022 and 15,400,678 in 2025. The second is valid votes less the winners’ published votes. Both are derived at build time from the data tree rather than carried as constants.
Reconciliation
All four first-segment values reproduce the constants they replaced. The non-winning band is computed on the official_votes column, which differs from votes by 77,197 in 2025; each bar’s total is derived as ballots cast less those same winners rather than merely checked against its own parts.
Caveats
Undervote and overvote are separable only for 2022 and 2025 (21.04% and 5.81% in 2025; 31.27% and 3.17% in 2022). For 2016 and 2019 COMELEC published no ballot composition at national level in any contest, so the two years carry a combined band. That band is final: the only document that might separate them is S4, which has not been read and whose inquiry was closed by decision on 22 September 2026. The 2019 figure — 41.04% of ballots cast producing nothing — is the worst in the series by a wide margin and is an anomaly, not a point on a trend.

D · Advocacies — Election and Registration tabs

IV.D.1

Party-list seats by advocacy — 17th to 20th Congress

Election
Sources
Seat rosters for the 17th, 18th, 19th and 20th Congresses, derived from the winners in S1S3 on the post-cancellation basis. Label set: S19, CPBRD’s own categories.
Construction
Seats held, counted by advocacy label, one panel per Congress. Twenty-four labels are used: CPBRD’s set with Regional Political Parties and Regional Groups combined into a single row, Regional Development. Every group receives a label — a best assignment supported by researched evidence wherever evidence could be found — and there is no Unclassified bucket on the chart.
Caveats
The assignment of groups to labels is this project’s own and is unverified. It is not COMELEC’s registered sector classification and has not been checked against one. The coding is graded internally by the strength of the evidence behind each assignment — grade A for documentary evidence, B for a published third-party classification or the registered name, C for a name-based assignment — and the grades are not shown on the chart. The labels are used as they stand, with no merging beyond the single combination stated above. This exhibit and IV.D.3 are the only places the coding is applied; whether it carries through to the rest of the dashboard is undecided.
IV.D.2

Seatless Advocacies

Election
Sources
As IV.D.1, with each year’s vote totals from S1S3 and the seat lines at IV.C.1.
Construction
Each line is a sector’s combined vote expressed as a multiple of that year’s seat line. The dashed rule is one seat. A filled dot means the sector held at least one seat that year; a hollow dot means it held none.
Caveats
A sector’s combined vote is an arithmetic sum across separate groups; it is not a vote any single group could have received, and the multiple is not a claim that the sector would have won that many seats had it fielded one vehicle. The shortfall figures stated for 2025 non-winners rest on the precinct file and are therefore maxima (IV.A.4). The classification caveat at IV.D.1 applies in full.
IV.D.3

Party-lists by advocacy — 2016 to 2025

Registration
Sources
Ballot populations from S1S3; label set S19.
Construction
The population is the groups that appeared on the ballot — 115 in 2016, 134 in 2019, 177 in 2022 and 155 in 2025 — counted in groups, not in votes or seats, on one basis throughout. Movement is the change in the number of groups carrying each label between 2016 and 2025.
Caveats
Ballot presence is not registration: a registered group that did not contest an election does not appear in that year’s count, and the series is therefore a record of who ran, not of who was on the roll. Group naming differs across years and sources — only 27 groups appear under an identical name in all four elections — so the series depends on a name crosswalk, and 49 rename cases remain unexamined by decision. The classification caveat at IV.D.1 applies in full.

E · Registration and delisting — Registration tab

IV.E.1

The 2028 filing deadline and the one-year requirement

Registration
Sources
S10 Resolution No. 11204, §6.
Construction
The card counts down to 18 December 2026, a Friday, in Philippine standard time, and states the one-year period for which the organization must already have existed at the time of filing. On 18 December 2026 the card reads “Today”; thereafter it counts up.
Caveats
The countdown is computed in the reader’s browser against Philippine time and is not a legal computation of the period. The resolution controls; the card is a convenience.
IV.E.2

Groups at risk for failure to participate — the 21

Registration
Sources
Ballot populations from S1S3; the three published orders S7S9.
Construction
Groups previously registered which did not appear on the ballot for both 2022 and 2025. The test applied is the participation limb of section 6(8) as construed at ¶ 8, requiring two consecutive failures of that kind; the two limbs are not added together.
Caveats
Absence from a ballot is evidence of non-participation, not proof of it, and the underlying list is built from published returns rather than from the register of registrations, which this project has not obtained. Exposure, not cancellation. These figures are project-derived; COMELEC has not classified these groups as at risk, and has cancelled no registration on this basis. See Part V(G).
IV.E.3

Lost in both 2022 and 2025 — the 38

Registration
Sources
As IV.E.2.
Construction
Groups that contested both 2022 and 2025 and obtained a seat in neither. The test applied is the second limb of section 6(8), again on two consecutive failures of its own kind. In the dashboard’s words: “Failure to obtain seats in either of these elections places these groups within one of two conditions for delisting, subject to official COMELEC order.”
Caveats
The statutory limb is expressed in the Act as a two per centum threshold; the dashboard identifies groups by failure to obtain a seat, which is the operative outcome on these returns but is not the statutory words. Exposure, not cancellation, as at IV.E.2.
IV.E.4

Comeback groups for 2028 — the cohort, graded

Registration
Sources
Ballot populations from S1S3; the three published orders S7S9.
Construction
Thirty-eight groups which contested 2022, appeared on the ballot in none of 2016, 2019 or 2025, and appear on none of the three published delisting orders. They polled 2,639,851 votes in 2022 between them. Each is graded by the strength of the evidence for its identity and status — A 5, B 31, C 2 — and two identity questions are recorded, both open.
Caveats
These are leads, graded. They are not findings, and they are not a claim that any registration survives. Absence from the three published orders is not evidence of continued registration: the orders record what COMELEC has acted on, and an order may exist that this project has not obtained. The two open identity questions concern possible name changes and are unresolved.
IV.E.5

Delisting Resolutions

Registration
Sources
S7, S8, S9, each transcribed in full.
Construction
Cancellations segmented by the ground the order laid them upon, with the groups that had won a seat earlier overlaid inside each band rather than as a separate strip. Across the three orders: failure to qualify 79, failure to participate 25, special ground 1; 32 had won a seat before. By order — Res. 10273 (19 Mar 2018): 18 / 5 / 1, of which 5 had won before; Res. 10696 (17 Feb 2021): 30 / 9, of which 15; Res. 11071 (1 Oct 2024): 31 / 11, of which 12.
Reconciliation
The two limbs of section 6(8) are held separate throughout and are never added, following ¶ 8. Names are reproduced in COMELEC’s own published spellings; where an order names an organization with no row in this project’s panel, no acronym is supplied for it.
Caveats
Where the delisting review could not establish that a group had won a seat earlier, the record reads “not located”, and that wording is deliberate: it records a search that came up empty, not a finding that the group never won. All of this is a count of what COMELEC has acted on, not of what the test would reach.
IV.E.6

Newly registered groups for 2025 — 42

Registration
Sources
S21
Construction
The number of groups Resolution No. 11074 lists as newly registered for the 2025 elections, counted from the project’s transcription of its list.
Caveats
Newly registered is not the same as appearing on the ballot; the First-timers card counts those that were.

F · Headline figures — Election tab

IV.F

The five stated figures

Election
247,754
The 2025 seat line after re-allocation — Murang Kuryente, on 0.62% of the vote. Four groups held no seat in the allocation of 16 May 2025 and hold one now: Gabriela (256,811), Abono (254,474), Ang Probinsyano (250,886) and Murang Kuryente (247,754). Duterte Youth’s cancellation released three of those seats; the fourth is the 64th, added by the En Banc when it resolved that 63 seats fell short of the 20% the Constitution requires. S2, S6, S11.
1 in 3
155 groups ran in 2025 and 57 won. The ratio has barely moved in a decade — 46 of 115, 51 of 134, 56 of 177, 57 of 155. S1S3.
6 — cleared 2%
Akbayan, Tingog, 4Ps, ACT-CIS and Ako Bicol cleared 2% of the 39,611,775 votes the seats were allocated on, and hold 12 of the 64 seats. Duterte Youth cleared it too, on 2,338,564 votes, but holds no seat. The series runs twelve, eight, six, six while the field grew from 115 groups to 155. Note that the denominator here is the base the seats were allocated on, which is not the 41,950,292 valid party-list votes. S2.
81.4%
Non-winners with no regional base: 79 of 97 drew less than 50% of their vote from a single region. The denominator excludes Duterte Youth, which is on the ballot and is not among the winners: 155 − 57 − 1 = 97. The join from official names to feed names runs through the project’s crosswalk, not a name match, which fails on all 57. S2.
One Third
Of the 57 groups that won a seat in 2025, 19 drew more than half their votes from a single province — each winner’s largest province column over its national total, with the precinct total as the denominator rather than the published canvass total. The claim in the words is arithmetic and is checked as such: 19 × 3 = 57. S2.

Part V

Limitations

A statement of the conditions that bound what this work can establish, and of the defects known to the author at the date of this note.

A  Nature and status of the study

¶ 14

This is an independent, single-author study conducted without institutional affiliation, external funding, research assistance or editorial oversight. It has not been peer-reviewed, refereed or independently replicated, and it is not offered for publication in any scholarly or professional journal. The apparatus of this note — the source register, the per-exhibit construction statements, the numbered references — is adopted because it makes the work auditable, and the reader is asked to audit it. It does not carry, and is not intended to imply, the warrant that peer review confers. Every finding is the author’s own and should be weighed as such.

A consequence follows for how the findings should be used. Where a figure here is to bear weight — in argument, in a filing, in advice to a client — the prudent course is to verify it against the source named in Part III rather than to rely upon this dashboard as authority. The register exists so that such verification is possible.

B  Source availability and impermanence

¶ 15

The study rests very largely on publicly available materials held by third parties, and principally by the Commission on Elections. Such materials are held at the publisher’s discretion. They may be amended, re-tabulated, superseded, withdrawn or decommissioned without notice, and no undertaking is given by any custodian that what was published will remain published. The consequence is that a figure verified against the record as it stood on the date of collection may not be reproducible against the record as it stands when read; and the study is to that extent contingent upon conditions outside the author’s control.

This is not a theoretical concern in the present case. Three instances arose during the currency of the project and are material to the weight the exhibits will bear. COMELEC’s 2016 and 2019 per-precinct results sites have been permanently decommissioned; the domains no longer resolve, and the underlying data was never archived, so the sub-national record for those two elections cannot now be obtained from the Commission at all. COMELEC’s 2022 per-board results interface refused access from 13 September 2026; this project’s walk of the preceding day is consequently the only copy in its possession and cannot be re-collected or independently re-verified from source. And the 2016 national canvass report survives only as scanned tally sheets which the project has been unable to read, so a question about that year’s ballot composition is closed by decision rather than resolved by evidence.

Where a source has become unavailable the exhibit that depended on it is not silently rebased. The basis is stated, the date of collection is given, and the limitation is disclosed at the point of use.

C  Reconstruction from secondary electoral feeds

¶ 16

Because of the decommissioning described above, the sub-national layers for 2016 and 2019 are not drawn from official returns. They are drawn from municipal returns collected by the OpenHalalan project from two broadcaster election feeds — GMA for 2016 and ABS-CBN for 2019. These are secondary sources, assembled under election-night conditions by newsrooms rather than by the canvassing authority, and they are used here because they are the surviving record and not because they are equivalent to one.

The ground for using them at all is a control rather than an assurance. The same project’s 2022 layer returns a national party-list total of 36,656,659, identical to the vote to this project’s own independent walk of all 1,659 COMELEC municipal canvass boards — the same number reached by two unrelated paths. That agreement is evidence that the collection pipeline is sound. It is evidence about one year, and it is offered as no more than that. The 2016 and 2019 feeds fall short of the official national totals by 3.12% and 1.53% respectively; the province tables are scaled to the official figure by largest-remainder rounding so that each file sums exactly, which corrects the aggregate but cannot correct the distribution. Sulu and Lanao del Sur are under-reported in both feeds, and neither carries overseas voting.

Province shares from these two years are accordingly treated as reliable and individual small-province figures as approximate. No 2016 or 2019 sub-national figure in this study should be cited as a COMELEC figure, and none is so described.

D  Incompleteness of the published record

¶ 17

Several measures the study would otherwise report across the whole series exist for part of it only, because they were never published for the remainder. Undervote and overvote are separable at national level for 2022 and 2025 and for no earlier year; sub-national blank-ballot figures exist for 2022 and 2025 alone; registered-voter tables are published by municipality from 2019 and by province only for 2016, with Metro Manila published for that year as a single region. These gaps are shown as gaps. They are not interpolated, modeled or carried forward from an adjacent year, and an exhibit that cannot cover a year says so on its face.

A related limitation attends the registration exhibits. This project has not obtained the Commission’s register of registered party-list organizations. The populations it works with are the groups that appeared on each ballot and the groups named in the three published delisting orders. Those are records of participation and of action taken; neither is a record of who is registered. Inferences about registration status are correspondingly indirect and are graded rather than asserted.

E  Classification and coding

¶ 18

The advocacy labels applied at IV.D are this project’s own. They use the CPBRD category set, with Regional Political Parties and Regional Groups combined into a single Regional Development row, but the assignment of individual groups to those categories is the author’s. It has not been verified against the Commission’s registered sector classifications, which this project has not obtained. Every group on the charts carries a label — a best assignment, supported by researched evidence where evidence could be found — and there is no Unclassified bucket; the effect is that the charts contain no visible signal of where the evidence is thin.

The coding is graded internally by evidentiary strength: documentary evidence, a published third-party classification or the registered name, or a name-based assignment alone. A material proportion rests on the weakest of those tiers. The grades are not shown on the charts, and the reader should therefore not treat any single bar as a precise count of groups sharing a sectoral character; the charts are offered as a picture of the distribution’s shape, and they should be read at that resolution.

Two further coding constraints bear on the series. Group naming differs across years and across sources — only 27 groups appear under an identical name in all four elections — so every cross-year count depends on a name crosswalk, and 49 rename cases remain unexamined by decision. Two sector-coding disagreements are recorded and unresolved, neither of which reaches a published chart.

F  Unresolved discrepancies

¶ 19

Four discrepancies are known, disclosed and unattributed. They are stated here together so that a reader need not assemble them from the exhibits.

(i) Two 2022 winners’ published totals differ from their canvass sum by more than one per cent — TUCP by 25,776 votes and Patrol by 4,138. The difference lies between COMELEC’s published canvass report and this project’s board walk, and has not been attributed to any canvassing unit. Those two groups carry the published figure on the vertical axis and their own canvassed share on the horizontal, so that neither axis mixes tables.

(ii) A residual difference of 47 votes in Duterte Youth’s 2025 total is recorded and unresolved. It did not arise from, and is not corrected by, the choice of figure the dashboard carries.

(iii) The 2025 precinct file is systematically low against the published winner totals — never high, median 0.128% low, worst 7.00%. Every non-winner figure derived from it is therefore a floor and every shortfall computed from it a maximum. This is a known bias, quantified but not corrected, because correcting it would substitute an estimate for a measurement.

(iv) The 2022 seat line is Akbayan’s published 236,226 rather than the canvass figure of 235,312. The choice is deliberate, is recorded once, and is applied consistently.

G  Inferential limits

¶ 20

The registration and delisting exhibits identify groups whose electoral record, on the published returns, answers the description in one limb of section 6(8) as construed at ¶ 8. That is the whole of what they assert. They do not assert, and nothing in them should be read as asserting, that any group identified stands delisted, is the subject of any proceeding, has been classified by the Commission as at risk, or will be acted upon. Cancellation of a registration is an act of the Commission upon a case before it, and the Commission acts upon what is before it. The exhibits record exposure on the face of the returns; the distance between exposure and cancellation is not a matter these exhibits can measure.

The same reservation governs the cohort at IV.E.4 in the opposite direction. That a group does not appear on any of the three published delisting orders is not evidence that its registration survives. The orders record what the Commission has published; an order not obtained by this project, or a proceeding not yet concluded, would not be visible to it. The cohort is offered as a set of graded leads for inquiry, and the grades are the measure of how far each has been taken.

Finally, the study is descriptive. It reports what the returns show about where votes came from and what a seat cost. It does not establish why any group polled as it did, and no causal claim about electoral strategy, organizational capacity or voter behavior is made or supported by these exhibits.

H  Temporal limits

¶ 21

The study covers the party-list elections of 2016, 2019, 2022 and 2025 and the registration position as it stands at the date in the masthead. The 2010 election is present in one of the underlying datasets but covers only 948 municipalities against some 1,634 in later years; it is excluded as unusable without heavier qualification than the exhibits could carry.

Two matters remain live and will alter the position if they move. Pilipinas Babangon Muli’s appeal against the cancellation of its registration is pending before the Supreme Court, and the 2025 seat-allocation basis shown here is the sheet that includes it; should the appeal be resolved the other basis may become the operative one. And the filing deadline at ¶ 11 falls on 18 December 2026, after which the registration exhibits describe a window that has closed. Neither is a defect in the study. Both are reasons to read it against its date.
