Okay, first of all, you don't go to a courthouse to force an investigation. You investigate first, and then go to court to put forth your claims and evidence. Second, investigations were done, and no evidence of voter fraud was found. Third, what you're saying is tantamount to saying "guilty until proven innocent", which is not how the law works. Fourth, merely claiming a election is rigged without evidence just because the candidate is sour grapes about losing said election, doesn't change reality. You aren't stating facts, just more rhetoric.
