Moss is a judge presiding in Star City.
Moss was the presiding judge in the trial of Peter Declan, an innocent man who was found guilty of murdering his wife and was sentenced to life in prison. He was eventually exonerated when his wife's real killer confessed.
Judge Moss also presided over a case brought against Oliver Queen, whom Quentin Lance arrested under suspicion that the playboy was actually The Hood. The case was headed by District Attorney Kate Spencer's office, but the charges were eventually dropped after John Diggle masqueraded as The Hood, seemingly proving Oliver's innocence.
