AUGUSTA, Maine (AP) — A Maine man who was stripped of his right to a lawyer wants to have his conviction tossed.

Joshua Nisbet, who’s serving a seven-year sentence for robbery, contends his constitutional rights were violated when a judge stripped him of right to counsel. The state says he forfeited his right to an attorney because he was unable to get along with any of his five court-appointed lawyers.

The state supreme court will hear arguments in the case on Wednesday.

Nisbet, who has no legal training, ended up handling his own defense while two standby attorneys assigned by the court assisted him without addressing the jurors. He may be the first criminal defendant in Maine to lose the right to a court-appointed attorney after qualifying for one based on his economic need.
