An attorney representing a man found guilty of murder told the state Supreme Court this week that his client was wrongly denied his right to testify in his own defense after the guilt phase of his trial had closed.

In oral arguments in Pittsburgh in a case captioned Commonwealth v. Baldwin , the lawyer, Kevin Abramovitz, told the justices that a panel of the Superior Court erred in relying on a federal appellate precedent — United States v. Peterson — in barring his client from taking the stand during the penalty phase.
