If you think the countercase is fake, and somebody's life and career are getting derailed, if you think you have valid reasons, you can try filing a petition in the appellate Court or High Court, to see whether the counter case can be disposed of quickly, or whether both the cases can be expedited.
He can also obtain permission to go abroad, even while the case is pending.
As a famous example, Sonia and Rahul are out on bail in National Herald case involving several crores, and Rahul frequently visits Bangkok and other foreign countries, even while the case is still pending. Whenever he wants to go abroad, Rahul Gandhi files a petition in the Court seeking permission to go abroad, and the Judge asks the Complainant, Dr Subramanian Swamy, whether he has any objection. Dr Swamy usually says he has no objection and then Rahul goes abroad.
You can see the YouTube channel called Virat Hindustan Sangam (VHS), yesterday (Sunday, April 13, 2025) there was a video where Dr Subramanian Swamy discussed about the current status of National Herald case, and he also explained that Rahul and Sonia are on bail, and he does not object when they file petitions to go abroad. It will give you an idea.
You can show all the papers to a few good criminal lawyers and explore the possibility of filing Criminal Revision Petitions or any other other appropriate petitions, to dispose of the counter case quickly, or to dipose of both the cases quickly, or to get permission to go abroad even while the cases are pending or any other reliefs. You may have to pay appropriate Court fee and surety, which may not be too high.
Try to explain why you think the counter case is fake.
It all depends on the exact details of the case.
No harm in filing the petitions. You would get to know some things, whether you are successful or not. Even if you fail, it may have some impact on the lower Court to dispose of the cases quickly.
