"Peckham was especially anxious to check the abuses of plurality, and his zeal involved him in several sharp disputes. ...A more serious case was that of Richard de la More, whose election as bishop of Winchester in 1281 Peckham refused to confirm, on the ground that he held two benefices with cure of souls without dispensation. The bishop-elect appealed to Rome, but, despite the opposition of some cardinals... Peckham won his case."
