Election Tampering Safeguarding the Integrity of Philippine Elections

How the Supreme Court upheld COMELEC's power to annul tampered election returns and order recanvassing to protect electoral integrity.


The integrity of Philippine elections rests on the accuracy and authenticity of election returns. When these documents are tampered with, the entire electoral process is compromised. In Mastura v. Commission on Elections (G.R. No. 124521, January 29, 1998), the Supreme Court affirmed the Commission on Elections' (COMELEC) broad authority to annul a canvass based on tampered returns and to order a recanvass using genuine copies, reinforcing the safeguards that protect the sanctity of the ballot.

The Facts of the Case

During the May 8, 1995 elections, Michael O. Mastura and Didagen P. Dilangalen were candidates for Representative of the First District of Maguindanao. During canvassing, Dilangalen objected to the inclusion of the Certificate of Canvass from the Municipality of Matanog, alleging it had been tampered with.

Acting on the objection, the COMELEC Second Division ordered the production and examination of the election returns from Matanog. Four ballot boxes were opened, revealing copies of the returns designated for the Municipal Trial Court (MTC) judge, the provincial board of canvassers, COMELEC, and the provincial board's copy of the municipal certificate of canvass.

Upon comparing the MTC judge's copy with the COMELEC copy across all 57 precincts, the COMELEC found no inconsistencies between these two copies. However, it determined that the Statement of Votes submitted by the Municipal Board of Canvassers did not reflect the true votes shown in the election returns. The COMELEC therefore annulled the canvass, constituted a new board, and ordered a recanvass using the COMELEC copies of the returns.

The Issue

The central question was whether the COMELEC committed grave abuse of discretion in annulling the canvass and ordering a recanvass based on the COMELEC copies of the election returns, rather than the copies in the possession of the Municipal Board of Canvassers.

The Ruling

The Supreme Court found no grave abuse of discretion on the part of the COMELEC. The Court ruled that COMELEC may suspend the canvass of votes pending inquiry into discrepancies between copies of election returns. Once returns are found to be falsified or tampered with, COMELEC can annul the illegal canvass and order the board to reconvene and proclaim winners based on genuine returns, or replace the board members if they refuse.

The Court emphasized that factual findings of COMELEC, as a constitutional body, deserve great respect. COMELEC has broad powers to ascertain the true results of an election and is not strictly bound by the rules of evidence in doing so.

All Copies Are Originals

Mastura argued that the COMELEC should have used the Municipal Board of Canvassers' copy because it was the "original." The Court rejected this argument, clarifying that all seven copies of the election returns are originals. The designation of the first copy for the municipal board is merely for distribution purposes and does not make it the sole original. COMELEC was therefore not required to retrieve and examine all seven copies.

Under Section 15 of Republic Act No. 7166 (The Synchronized Elections and Electoral Reforms Law of 1991), COMELEC is given leeway to correct manifest errors in certificates of canvass or election returns. The law does not specify that COMELEC must use any particular copy.

Practical Takeaways

  • COMELEC's supervisory power is broad. COMELEC exercises direct supervision and control over boards of canvassers and may annul canvasses based on tampered or incorrect returns.
  • All copies of election returns are originals. No single copy holds superior evidentiary weight over others; COMELEC may examine whichever copies it deems necessary.
  • Factual findings of COMELEC are highly respected. Courts will not disturb COMELEC's factual determinations absent a clear showing of grave abuse of discretion.
  • Timely recourse matters. Parties must follow the proper procedural ladder, including seeking reconsideration from the COMELEC en banc before elevating matters to the Supreme Court.
  • The remedy for tampering is recanvass, not silence. When returns are tampered with, COMELEC's remedy is to annul the defective canvass and order a fresh one based on genuine returns.
