Referred to the Committee on Local GovernmentNow
Under committee study or floor debate. Amendments are still possible, and this is the stage where public input carries the most weight.
What this measure does
Three sections and one page. This renames the Municipality of Sultan Mastura in Maguindanao del Norte to the Municipality of Subpangen.
Section 2 makes the change conditional: the renaming takes effect only on ratification by a majority of the votes cast by qualified voters in a plebiscite conducted and supervised by COMELEC in the present Municipality of Sultan Mastura. The expenses of that plebiscite are to be borne by the Bangsamoro Government.
The Act takes effect 15 days after publication. There is nothing else in it — no transitional provision for records, seals, signage or contracts held in the old name.
Why it was proposed
No explanatory note is attached and the bill offers no reason. Sultan Mastura is named for a historical figure; Subpangen is a place name.
What the bill does say, by requiring a plebiscite, is that the author treated the name of a municipality as belonging to the people who live in it rather than to Parliament. Renaming is within the region's power to legislate over its own political subdivisions, and the choice to put it to a vote anyway is the substantive decision in the document.
Who it affects
- Residents of Sultan Mastura, who would vote on their municipality's name.
- The municipal government, whose records, seal, signage and contracts all carry the existing name.
- The Bangsamoro Government, which pays for the plebiscite.
- COMELEC, which conducts and supervises it.
Who would implement it
- Commission on Elections — conduct and supervision of the plebiscite in the present Municipality of Sultan Mastura
- The Bangsamoro Government, which bears the plebiscite expenses
Funding
Carries an appropriation. No amount is named. The expenses of the plebiscite are borne by the Bangsamoro Government — a departure from the municipality creation bills in this registry, which charge the plebiscite to COMELEC's own appropriations.
What changes if it becomes law
- Sultan Mastura would become Subpangen, if its voters approve.
- The region pays for the plebiscite rather than passing the cost to COMELEC.
Raised during deliberations
No published record of the debate on this measure. Parliament’s journals cover sittings up to March 2023 only, and no committee report on it has been published.
What to notice
Requiring a plebiscite to change a name is the choice worth noting, and it turns out to be the region's settled practice rather than this bill's innovation. BAA 90, which renamed Datu Blah T. Sinsuat to West Upi in May 2026, does the same thing: it conditions the change on ratification by a majority of the municipality's own voters, in a plebiscite run by COMELEC under the Local Government Code's procedure for changes of name. So on the central question this bill is in line with what Parliament went on to enact.
Who pays is also consistent, and it runs the more principled way. Every municipality *creation* bill in this registry charges the plebiscite to COMELEC's own appropriations — the region spending a national agency's money on a regional decision. This bill has the Bangsamoro Government bear the cost, and BAA 90 charges it to the Contingent Fund of the Office of the Chief Minister. Both put the cost of a regional referendum on the region.
Where this bill falls short of the enacted model is in what it leaves untouched. BAA 90 amends Muslim Mindanao Autonomy Act No. 198 — the ARMM-era statute that created the municipality under its original name — so that the renaming reaches the law the name comes from. This bill amends nothing. Sultan Mastura was itself created by an earlier statute, and renaming a municipality without touching the act that named it leaves 2 instruments disagreeing.
What the bill also omits is everything that follows a renaming. A municipality's name appears on its seal, its records, its land titles, its business permits, its road signs and every contract it is party to, and statutes that rename places normally carry a provision saying that references to the old name are read as references to the new one. This one does not, which would leave a genuine question about the continuity of instruments executed as Sultan Mastura.
