G.R. No. 104961 - Aniag, Jr. vs. Commission on Elections

On 11 December 1991, the Commission on Elections (COMELEC) issued Resolution No. 2323 (“Gun Ban”) promulgating rules on bearing, carrying, and transporting firearms or other deadly weapons during the election period.
On 26 December 1991, COMELEC issued Resolution No. 2327 providing for the summary disqualification of candidates engaged in gunrunning, use or transport of firearms, organization of special strike forces, and establishment of spot checkpoints.

On 10 January 1992, Sergeant-at-Arms Taccad of the House of Representatives requested petitioner–then Congressman Aniag–to return two firearms issued to him.
On 13 January 1992, petitioner instructed his driver, Ernesto Arellano, to pick up the firearms from petitioner’s residence and deliver them to Congress.
At around 5:00 PM the same day, the Philippine National Police set up an unmarked checkpoint about 20 m from the Batasan Complex entrance.
Without a warrant or prior notice, fourteen armed officers flagged down Arellano’s car, conducted an extensive search of the trunk, and seized the two firearms packed in gun cases and a bag.

On 15 January 1992, the City Prosecutor released Arellano after finding his sworn explanation meritorious.
On 28 January 1992, petitioner was invited to confirm Arellano’s testimony and urged the Prosecutor to exonerate Arellano.
On 6 March 1992, the Prosecutor recommended dismissal of both Arellano’s and the “unofficial” charge against petitioner.
On 6 April 1992, COMELEC issued Resolution No. 92-0829 directing the filing of information against petitioner and Arellano for violation of Sec. 261(q) of B.P. Blg. 881 in relation to Sec. 32 of R.A. 7166, and to show cause why petitioner should not be disqualified under Resolution No. 2327.
On 13 April 1992, petitioner moved for reconsideration and to hold in abeyance the administrative and criminal proceedings; on 23 April 1992, COMELEC denied the motion.
Petitioner filed a petition for declaratory relief, certiorari, and prohibition before the Supreme Court, assailing Resolutions Nos. 2327, 92-0829, and 92-0999.

Whether Resolution No. 2327 is unconstitutional for creating presumptions of guilt and summary disqualification without final conviction.
Whether Resolutions Nos. 92-0829 and 92-0999 lack legal and factual bases for directing criminal prosecution and electoral disqualification.

Whether the PNP’s warrantless, non-visual search of Arellano’s vehicle violated Secs. 2 and 3(2), Art. III of the Constitution.
Whether Arellano’s passive acquiescence to the checkpoint search constituted valid consent.

Whether petitioner’s Sixth Amendment–like right to a preliminary investigation was violated by not formally impleading him as a respondent before the City Prosecutor.
Whether the omission of petitioner’s inclusion in the initial charge sheet deprived him of the reasonable opportunity to present his defense.
