Hairston v. United States

Summary

The District of Columbia Court of Appeals held that the trial court erred by giving an aiding-and-abetting instruction because no evidence admitted for its truth supported a finding that Hairston was an accomplice rather than the principal offender. The court declined to conduct a harmless-error analysis because the government had not timely argued harmlessness, reversed the assault-with-a-dangerous-weapon conviction, and remanded for a new trial on that charge. The court affirmed Hairston's conviction for carrying a dangerous weapon.

Holdings

1. The trial court erred by giving an aiding-and-abetting instruction because no evidence admitted for its truth allowed the jury to find that Hairston aided another person who was the principal offender rather than personally committing the assault.
2. The court declined to conduct a harmless-error analysis because the government failed to argue harmlessness in a timely manner and harmlessness was not obvious.

Questions Presented

1. Whether the trial court erred by instructing the jury on aiding and abetting when no evidence admitted for its truth supported a finding that Hairston was an accomplice rather than the principal offender.
2. Whether the instructional error could be deemed harmless when the government did not argue harmless error in its brief and did not meaningfully argue it at oral argument.
