Background
Richard Mershon was convicted after a jury trial of offenses arising from a confrontation in a restaurant parking lot. The evidence showed that, while intoxicated, he punched two people, fired at bystander Rollins, shot and injured bystander Trivelpiece, threatened another person, and suffered a self-inflicted gunshot wound to his hand. The Oregon Court of Appeals previously affirmed most of his convictions but reversed the attempted-murder conviction involving Rollins because it rested on a nonunanimous verdict. That charge was later dismissed.
Mershon sought post-conviction relief, alleging that trial counsel inadequately handled several issues: firearms evidence bearing on Rollins’s claim that Mershon fired at “point blank” range; evidence of Trivelpiece’s blood alcohol content in support of self-defense; expert testimony concerning whether Mershon voluntarily waived his Miranda rights while intoxicated and medicated; and evidence concerning the number of shots fired. The post-conviction court denied relief, and Mershon appealed.
The Court’s Holding
The Court of Appeals affirmed. It held that Mershon failed to establish prejudice from counsel’s handling of the “point blank” testimony. The attempted-murder charge involving Rollins had been dismissed, and Mershon did not show that proposed gunshot-residue evidence would have affected the jury’s assessment of Rollins’s credibility on the remaining charges.
The court also held that counsel reasonably decided not to pursue evidence of Trivelpiece’s intoxication after consulting a self-defense expert, because no evidence indicated that Trivelpiece was using or about to use deadly physical force. Counsel likewise made a reasonable strategic decision not to call an expert at the Miranda hearing after an expert advised that pain medication would not have impaired Mershon’s ability to waive his rights and counsel concluded that Mershon appeared lucid.
Finally, the court rejected the claim concerning the number of shots. Trial counsel had argued that only two bullets were fired, and Mershon failed to show prejudice because the charges did not turn on whether he fired three shots or four.
Key Takeaways
- A post-conviction petitioner must prove both constitutionally deficient performance and prejudice; an alleged error tied to a charge that was later dismissed may not satisfy the prejudice requirement.
- Counsel reasonably declined to pursue a victim’s blood alcohol evidence when expert advice and the record indicated that it would not support the legal requirements for using deadly force in self-defense.
- Counsel need not search for a different expert merely because a later expert offers a more favorable opinion, particularly when the original consultation reasonably supported counsel’s strategy.
Why It Matters
The decision illustrates the substantial deference Oregon courts give reasonable tactical choices made after investigation and expert consultation. A later-developed expert opinion does not by itself establish that trial counsel performed inadequately.
It also emphasizes that post-conviction relief requires a concrete connection between counsel’s alleged error and the outcome. Claims involving an immaterial factual dispute, or a conviction that has already been reversed and dismissed, will fail without proof that the alleged deficiency could have affected the remaining convictions.
