If a parent or guardian is brought before the court for failing to comply with the terms and conditions of an order of probation issued under section 36 hereof, or of an order of protection issued under section 35 or section 11 hereof, and if, after hearing, the court is satisfied by competent proof that the parent or guardian did so willfully and without just cause, the court may revoke the order of probation or of protection and enter any order that might have been made at the time the order of probation was made.
