Who decides, is the crucial question? The fact that we have courts of law where judges routinely make decisions about difficult, gray area questions, tells me that this is a solved problem. I can imagine a special court (or board or whatever; just as long as it falls under the judiciary branch and is therefore independent) set up to make quick rulings. There should of course be a way to appeal the rulings to a normal court.
