G.R. No. 206354 | 2019-03-13

DECISION
 
LEONEN, J.:
 
A petition for certiorari, pertaining to the regularity of a preliminary investigation, becomes moot after an information is filed and a trial court issues an arrest warrant upon finding probable cause against the accused.[1]

This resolves a Petition for Certiorari and Prohibition[2] praying that the Department of Justice be prohibited from proceeding with the preliminary investigation in NPS Docket No. XVI-INV-13C-00092 due to its lack of impartiality and independence, in violation of Police Superintendent Hansel M. Marantan (Marantan)'s right to due process and equal protection of the laws.
