If the weather is not marginal, you don't have to divert. This is at PIC discretion and common sense. As long as you land with at least 30 min in the tank, no one can tell you anything. Obviously it's not a situation you want to be. But in good weather conditions with no or little delay expected for the approach, it's actually safer to cancel you alternate fuel and shoot the approach and land at destination instead of initiating a diversion to your alternate with zero extra fuel.. A slight delay or one go around and you are in a mayday fuel situation.
