He can bust people out of prison and protect them from arrest if they think their actions are not crimes. He can imprison you even if you did nothing against mundane law and no cop will be able to save you.
Him choosing to follow civilian authority is a possibility, but even it's going to have its limits. Would Superman really let injustice happen just because president and congress and whatnot demand it or would he protect would-be victims of prosecution. Would he really let someone get away with behaviour he particularly opposes even if government says it's not a crime?
Like I said, in cape stories the scenarios are not very realistic - superheroes usually don't make a stand against something that audience can identify with, but everyone probably has some strong beliefs that they aren't allowed to act on. Superman would not have such a restraint. Maybe he will make a stand against homosexual corrupting the youth. Maybe he would make a stand against border control. Maybe he's a feminist who would punch you into space for looking at women the wrong way or maybe he will convert into Islam and do all of the above to usher new age of Global Sharia. It won't happen of course unless it's a parody or deconstruction because our ability to like Superman hinges on him not acting like a dictator. But it's unlikely he would be entirely not if he was real.
