Ngb Found Cheating In An Event And Choose To Do Nothing About It

I am a professional jump roper(yeah it’s weird I know), but recently I participated in a qualifier for the U.S national team and got through for a few events. 1 even however I uncovered both an ethical violation by the rules and also a parent judge cheating for their child. I reported it to the proper channels in my national governing body and there is evidence of them cheating for their child however they are saying they can’t do anything about it. What should my next steps be if I want to take this action to court.
