A judges control over his court is not by law, but rather by judicial authority to maintain his judicial independence, with a long tradition of common law behind it. Like other judicial authority, it is subject to appeal to other judges. Normally you get one appeal always, but you can ask for more, but the higher courts get to choose their cases, another long tradition of common law.
A judge independent of the law!? And you were disparaging me of my comments... you, my friend, have chutzpa.
