Lazatin vs. Desierto
Case
G.R. No. 147097
Decision Date
Jun 5, 2009
Congressman Lazatin accused of illegal CDF use; Ombudsman upheld prosecutorial authority under R.A. No. 6770, dismissing certiorari petition.

Case Summary (G.R. No. 1523)

Issues Presented

  1. Whether the Ombudsman acted with grave abuse of discretion or in excess of jurisdiction by disapproving the OSP resolution.
  2. Whether the Ombudsman’s disapproval rested on misapprehension of facts and conjectures.
  3. Whether R.A. 6770 is unconstitutional for subsuming the OSP under the Ombudsman contrary to the constitutional separation between investigative and prosecutorial functions.

Constitutionality of R.A. 6770 under the 1987 Constitution

The Court reaffirmed that the 1987 Constitution vests the Ombudsman with powers “to exercise such other functions or duties as may be provided by law.” Congress validly conferred prosecutorial authority and placed the OSP under the Ombudsman through R.A. 6770. Precedents (Acop v. Office of the Ombudsman; Camanag v. Guerrero; Office of the Ombudsman v. Valera; Perez v. Sandiganbayan) uniformly upheld the statute’s constitutionality.

Stare Decisis and Precedential Value

Under Article 8, Civil Code, and settled doctrine, Supreme Court rulings form part of the legal system and are binding unless strong, compelling reasons justify departure. Petitioners failed to demonstrate any justification to overturn decades of consistent jurisprudence affirming the Ombudsman’s prosecutorial powers and control over the OSP.

Scope of Certiorari Review

Certiorari under Rule 65 corrects errors of jurisdiction and grave abuse of discretion, not mere errors of judgment or factual re-evaluation. Alleged misapprehensions underlying the Ombudsman’s finding of probable cause cannot be addressed via certiorari, which does not permit re-weighing evidence or reassessing credibility.
