Supreme Court justices on Wednesday appeared ready to give the green light to efforts by a New Orleans man to win compensation for prosecutorial misconduct that put him behind bars for more than two decades for a murder he did not commit.

The Court heard arguments in the case of Connick v. Thompson in which former New Orleans District Attorney Harry Connick maintains that his office should not be held liable for what he contends was a single incident of failing to hand over exculpatory evidence to the defense before trial.
