1. If the CBI moves the Supreme Court to challenge the Gujarat HC order then you will have to contest the case in the SC. The SC has unfettered and unquestionable power to reverse the judgment of the High Court.
2. If you win in the SC also that would be the end of the legal battle. Supreme Court is the highest court in the country. No tribunal or court or any executive authority can sit in appeal over the SC.
3. You cannot stop the CBI from going to the SC. What you can do is contest the case in the SC.
