Background

A jury convicted Manuel Daniel Delgado of murder and first-degree assault. After the judgment of conviction became final, Delgado sought post-conviction relief.

Delgado alleged that trial counsel failed to negotiate a plea agreement with the state, amounting to inadequate assistance under Article I, section 11, of the Oregon Constitution and ineffective assistance under the Sixth and Fourteenth Amendments. The post-conviction court denied relief, and Delgado appealed.

The Court’s Holding

The Oregon Court of Appeals affirmed. Relying particularly on the post-conviction court’s findings that trial counsel was credible and Delgado was not, the court concluded that counsel’s performance was not constitutionally deficient.

The court also held that Delgado failed to prove prejudice resulting from counsel’s challenged acts or omissions. Because his claims failed on both deficient performance and prejudice, he was not entitled to post-conviction relief under either the state or federal constitutional standard.

Key Takeaways

  • A post-conviction petitioner alleging inadequate or ineffective assistance must prove both deficient performance and resulting prejudice.
  • The Court of Appeals accepted the supported historical findings of the post-conviction court, including its credibility determinations.
  • Delgado failed to establish either that counsel performed deficiently in connection with plea negotiations or that the alleged failure caused prejudice.

Why It Matters

The decision illustrates the importance of credibility findings and proof of prejudice in post-conviction claims involving plea negotiations. An allegation that counsel failed to pursue a plea agreement is insufficient without proof that counsel acted unreasonably and that the failure affected the outcome.

This is a nonprecedential memorandum opinion under ORAP 10.30 and may not be cited except as permitted by ORAP 10.30(1).
