Well, Jerry, actually no it isn't.
It's just like when a cop knocks on your door and asks if he can come in and look around. You are well within your rights to say "NO!", and his alternative is to come back with a warrant (if he can get one). However, the vast majority of people don't exercise that right. It's the whole reason why suspects have to be 'Mirandized' now, because so many people weren't aware/didn't exercise their rights.
So, he can certainly ASK for them, but if he REQUIRES them as part of the process, that's where you can insert your complaint. Obviously, few people ever turned him down, though.
