My first question is: Have you tried getting bail frmo High Court?
Now, coming back to your query, I would like to tell you that the pivot point in your case is that the girl stayed with the boy for 8 months. After how many months did the parents of the girl filed FIR? Is there any delay?
Also, as the girl stayed with the boy, there must have been some rent receipts where they lived. There must be some neighbours who might have seen them living together peacefully. Why don't you take these evidences and then approach the court.
Just by saying that the case is false would not save your friend and court would not allow bail in such serious allegations.
Try to explain to the court that the girl went with the boy on her own and now because of her family pressure she is not able to speak truth. These charges have been slapped by police under the influence of the family of the girl and that an innocent is suffering in jail because of false case.
Pls hire a good lawyer who can make the court understand the need for bail and who can convince. I think a good lawyer (if you talk about Delhi), would not take more than Rs. 50,000 for this regular bail.
If you can get an opportunity for mediation or to talk to the girl then if the girl agrees to be in your favor, then you can directly approach the High Court and get this matter quashed.
Such cases in general are rampant wherein girl elope with the boy and then later under her family pressure give statement against the boy. This is very pathetic and sad situation for men. A girl who endeavored to support a boy and then later retracts should at the first go think 100 times because in the end the girl is safe and need not undergo any problem but the boy who is not at all at fault has to undergo so much trauma. Alas!
Please feel free to ask if in case you have any other query. Also if in case your case is in & around Delhi then I can suggest a good Criminal Lawyer who would be very reasonable in his fees..
