Under Philippine law, the question “Who becomes mayor if a sitting city or municipal mayor dies in office?” is governed primarily by the 1987 Constitution and the Local Government Code of 1991 (Republic Act No. 7160), together with its Implementing Rules and Regulations (IRR) and various DILG/COMELEC issuances.
Below is a structured, article-style discussion of everything essential you need to know on the topic, in the Philippine context.
I. Constitutional and Statutory Framework
1. Constitutional basis
The 1987 Constitution does not spell out detailed succession rules for local elective officials, but it:
- Recognizes local autonomy and authorizes Congress to enact a Local Government Code (Article X).
- Requires that local officials, including mayors, be elected and serve fixed terms.
The actual mechanics of succession when a local official dies in office are found in statutory law, not in the Constitution.
2. Local Government Code of 1991 (RA 7160)
The key provisions are:
- Section 44 – Permanent Vacancies in the Offices of the Governor, Vice-Governor, Mayor, and Vice-Mayor
- Section 45 – Permanent Vacancies in the Sanggunian
- Section 46 – Temporary Vacancy in the Office of the Local Chief Executive
- Related IRR provisions that define terms and spell out procedures.
For our topic, Section 44 is central.
II. “Permanent Vacancy” vs. “Temporary Vacancy”
Before answering “who assumes,” you need to know what kind of vacancy you have.
1. Permanent vacancy
Under RA 7160, a permanent vacancy in an elective local office arises when the incumbent:
- Dies;
- Resigns;
- Is removed from office by law;
- Is permanently incapacitated (e.g., serious illness, disability, or other legal incapacity);
- Voluntarily refuses to assume office;
- Fails to qualify (e.g., failure to take oath or assume within the period prescribed by law);
- Or otherwise permanently ceases to discharge the functions of the office.
👉 Death of the mayor clearly creates a permanent vacancy.
2. Temporary vacancy
A temporary vacancy in the office of the mayor arises in situations such as:
- Approved leave of absence;
- Travel abroad;
- Preventive suspension;
- Other forms of temporary incapacity, as recognized by law.
In temporary vacancy, the official returns to office when the cause ceases. Succession is merely “acting” or “officer-in-charge” (OIC), not permanent.
Since you are asking about death, we are firmly in the realm of permanent vacancy.
III. Basic Rule: Vice Mayor Becomes Mayor
Assume a city or municipal mayor dies in office (for any cause: illness, accident, etc.). Under Section 44 of RA 7160:
If a permanent vacancy occurs in the office of the city or municipal mayor, the city or municipal vice mayor automatically becomes the city or municipal mayor.
Key points:
Automatic succession
- The vice mayor assumes the office of mayor by operation of law.
- No appointment is needed from the President or any other official.
- COMELEC does not call for a special election for mayor in this situation.
Full title and powers, not merely “acting mayor”
- The vice mayor does not just “act as mayor”; they become the mayor.
- They hold the title “City Mayor” or “Municipal Mayor” and exercise all powers, functions, and prerogatives of the office.
Term of office of the new mayor
- The vice mayor-turned-mayor serves the unexpired portion of the original mayor’s term.
- This is important for later questions like term limits, but as far as succession is concerned, the new mayor completes the term.
Oath and assumption
Although the succession is automatic by law, in practice the vice mayor:
- Takes an oath of office as mayor (often before a judge or proper official); and
- Issues or receives a formal assumption document for record-keeping and administrative purposes.
IV. What Happens to the Vice Mayor’s Office?
1. After the vice mayor becomes mayor
Once the vice mayor assumes as mayor, a permanent vacancy is created in the office of the vice mayor.
So the chain continues:
The highest-ranking member of the sangguniang panlungsod (for cities) or sangguniang bayan (for municipalities) becomes the vice mayor.
This is still under Section 44 of RA 7160.
2. Who is the “highest-ranking sanggunian member”?
The “ranking” of sanggunian members is determined based on the number of votes obtained in the most recent election for that position:
- Highest number of votes = highest-ranking councilor.
- Next highest = second-ranking, and so on.
If there is a tie in the number of votes:
- The one with the higher percentage of votes relative to the total number of registered voters in the district at the last election is deemed higher in rank (this is how the Code resolves certain ties).
- If still unresolved, COMELEC may resolve it, typically through drawing of lots (in line with election law principles).
The highest-ranking councilor becomes the new vice mayor and serves the unexpired term of that office.
V. Chain Succession in Case of Simultaneous Vacancies
What if both the mayor and vice mayor die in the same incident (e.g., accident) or otherwise both offices become permanently vacant at the same time?
RA 7160 anticipates this scenario:
In case of permanent vacancies in both the offices of mayor and vice mayor, the highest-ranking sanggunian member becomes mayor, and the second highest-ranking sanggunian member becomes vice mayor.
Thus, the line of succession for a city or municipality (strictly under RA 7160) looks like this:
- Mayor
- Vice Mayor
- Highest-ranking councilor (for mayor, if both mayor & vice mayor posts are vacant)
- Second highest-ranking councilor (to fill vice mayor spot in that same scenario)
Each one who moves up leaves a vacancy behind in the sanggunian, which is then filled via Section 45.
VI. Filling Vacancies in the Sanggunian After Succession
When councilors move up to become vice mayor (or even mayor), their seats in the sangguniang panlungsod or sangguniang bayan also become vacant.
This is governed by Section 45 – Permanent Vacancies in the Sanggunian.
1. General rule for party-affiliated councilors
If the vacating councilor belongs to a registered political party:
The President of the Philippines appoints the replacement upon nomination by:
- The political party to which the vacating councilor belonged at the time of election;
- Provided that the nominee is a member of the same political party and is qualified for the office.
2. If the vacating councilor is independent
If the vacating member did not belong to any political party at the time of election:
- The vacancy is filled by a presidential appointment upon recommendation of, or in coordination with, local authorities and in accordance with law and regulations.
- The appointee must have the same qualifications as the office and meet the residency, age, and other requirements.
3. Ex officio members (Liga, SK)
For ex officio members of the sanggunian like:
- Liga ng mga Barangay president
- Sangguniang Kabataan Federation president
Vacancies are usually filled by electing a new federation president at the relevant level, who then becomes ex officio member.
While this is adjacent to our succession topic, it matters because the ranking of sanggunian members usually concerns only regularly elected councilors, not ex officio members, when determining who succeeds as vice mayor.
VII. Distinguishing “Acting Mayor” from “Successor Mayor”
To understand the effect of death in office, it helps to contrast with temporary vacancy under Section 46.
1. Temporary vacancy – acting capacity only
When the mayor is:
- On official leave;
- Out of the country temporarily;
- Under preventive suspension;
- Otherwise temporarily unable to perform duties;
the vice mayor acts as mayor but:
- He/she does not lose the title “vice mayor”;
- He/she is often referred to as acting mayor or officer-in-charge.
When the mayor returns, the acting mayor returns to being full-time vice mayor.
2. Permanent vacancy – full succession
In contrast, if the mayor dies (or resigns, is removed, etc.):
- The vice mayor permanently becomes the mayor (not merely acting).
- The office of vice mayor becomes permanently vacant, and the succession chain under Section 44 kicks in.
This distinction matters:
- In a permanent vacancy, the successor consumes the term and gets counted for term limit purposes.
- In a temporary vacancy, acting as mayor does not create a separate term for term-limit purposes.
VIII. Term Limits and Succession
The three-term limit rule applies to local elective officials, including mayors and vice mayors. The question often arises:
If a vice mayor becomes mayor because the mayor died, does that count as one term as mayor?
The general legal understanding:
A “term” is the full three-year period for which the official is elected.
However, jurisprudence has recognized that service by succession can still count as a term for certain term-limit purposes if:
- The official actually served the term (or a substantial part of it) in a capacity equivalent to a full-fledged term, and
- There is no interruption in service that resets the term.
But this is a nuanced area and often litigated. The detailed application depends on case law and specific factual scenarios (how long they served, whether reelection occurred, etc.). For purposes of “who assumes when the mayor dies”, it is enough to say:
- The vice mayor becomes mayor and serves the remainder of that term, and
- The impact on term limits must be analyzed in the context of the particular case and prevailing jurisprudence.
IX. Administrative Practice: How Succession Actually Happens
In practice, when a city or municipal mayor dies in office, several steps occur:
Certification of death / occurrence of permanent vacancy
The death is recorded (civil registry, hospital, etc.), and local officials notify:
- The DILG;
- The Sangguniang Panlungsod / Bayan;
- Often the COMELEC for record purposes.
Assumption by the vice mayor
- The vice mayor formally takes oath as mayor.
- A Notice of Assumption is prepared and transmitted to relevant government offices (DILG, DBM, COA, etc.).
Reorganization of the sanggunian
- With the vice mayor now mayor, the presiding officer of the sanggunian changes.
- The highest-ranking councilor assumes as vice mayor (with his/her own oath of office and assumption documents).
Appointment process for new sanggunian members
- The political party (if any) nominates a replacement for the vacated sanggunian seats.
- The President appoints the replacement(s), subject to the requirements of RA 7160 and related rules.
Updating of payroll, signatories, bank and contractual authority
- Financial and administrative systems are updated to reflect the new mayor’s signatories and authority.
X. Edge Cases and Problem Situations
1. Disputes on “ranking” of councilors
Occasionally, there may be disputes such as:
- Recount or election protest affecting vote totals;
- Questions about whether ex officio members are included in the ranking;
- Late proclamations or annulment of election results.
In such cases, the COMELEC and, ultimately, the courts may have to resolve who is the “highest-ranking” councilor. While the law is clear, actual application sometimes depends on election law rulings.
2. Death of mayor-elect before assumption
Another scenario is when a mayor-elect dies before taking office:
If the mayor-elect dies before noon of June 30 (the usual assumption date), there are arguments about whether:
- A failure to assume combined with death triggers the same Section 44 permanent vacancy rule, and
- Whether the vice mayor-elect then assumes as mayor upon commencement of the term.
The principle still comes back to Section 44’s language on failure to qualify and permanent vacancy, but application may depend on how COMELEC and the courts interpret the timing and nature of the vacancy.
3. Simultaneous death or incapacity of multiple successors
In more extreme situations (e.g., disaster, terrorism, or accident involving multiple officials):
- The line of succession (mayor → vice mayor → highest-ranking councilor → second highest, etc.) is followed as far as possible.
- If the succession line is exhausted or complicated, national authorities (DILG, the President, COMELEC, and sometimes the courts) may intervene to stabilize local governance consistent with the Code, election laws, and emergency measures.
XI. Summary: Core Rule in One Page
When a city or municipal mayor dies in office in the Philippines:
The death creates a permanent vacancy in the office of mayor under RA 7160.
That vacancy is filled automatically by the incumbent vice mayor, who:
- Becomes the new mayor (not just acting);
- Exercises all powers of the office; and
- Serves the unexpired portion of the term.
The vice mayor’s office becomes permanently vacant and is filled by the:
- Highest-ranking sanggunian member, who becomes vice mayor.
If both mayor and vice mayor positions are simultaneously vacant:
- The highest-ranking councilor becomes mayor;
- The second highest-ranking councilor becomes vice mayor.
The resulting vacancies in the sanggunian are then filled by:
- Presidential appointment based on the nomination of the political party of the vacating member (or other applicable rules), consistent with Section 45 of RA 7160.
Everything else—administrative forms, notifications, and finer questions on term limits and election disputes—builds around these core succession rules in the Local Government Code.
