Background

Tyrone Neil Murphy sought post-conviction relief from convictions based on guilty pleas to two counts of first-degree sodomy. He entered the pleas after the Oregon Court of Appeals reversed his earlier convictions because the verdicts were nonunanimous and remanded for a new trial. The plea agreement resolved numerous charges, substantially reduced Murphy’s sentencing exposure, and imposed a stipulated 204-month sentence.

After the post-conviction court denied relief, Murphy raised seven assignments of error on appeal. His arguments included prosecutorial misconduct, inadequate assistance concerning a possible double-jeopardy defense, coercion of his guilty plea, constitutional vagueness of Oregon’s first-degree sodomy statute, actual innocence, and inadequate assistance by post-conviction counsel.

The Court’s Holding

The Oregon Court of Appeals affirmed. It held that Murphy’s standalone prosecutorial-misconduct theory, double-jeopardy-related inadequate-assistance theory, actual-innocence theory, and claims concerning post-conviction counsel were unpreserved because they were not pleaded in the operative amended petition and the post-conviction court did not rule on them. Without a ruling, those assignments provided no basis for reversal.

The court also upheld the rejection of Murphy’s coercion claim. Supported findings established that Murphy signed a plea petition, told the plea court that he understood the agreement, denied being pressured or coerced, and was not credible when he later claimed otherwise. The court further held that Murphy knowingly relinquished his vagueness challenge to ORS 163.405 by pleading guilty and, independently, failed to establish that the statute was unconstitutional.

Key Takeaways

  • A post-conviction claim generally cannot support reversal when it was not pleaded and the post-conviction court never ruled on it.
  • Appellate courts are bound by supported factual and credibility findings concerning whether a guilty plea was voluntary.
  • A guilty plea ordinarily waives nonjurisdictional defenses, and Murphy did not establish that ORS 163.405 was unconstitutionally vague.

Why It Matters

The decision underscores the importance of including every intended ground for relief in the operative post-conviction petition and obtaining an express ruling on each claim. Arguments raised only in a pro se memorandum, or developed for the first time on appeal or in reply, may be procedurally unavailable.

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