How to close the case & get passport

Dear Sir/ Mam, When my cousin brother was doing engineering he & his friend were coming back from a party at night. All have taken alcohol. At a petrol pump they stop to fill petrol in their vehicles. Their a unknown guy who was total drunk came near a friend & talk to him. After some time the discussion became hot & that guy started hitting him. Then both of them started fighting & to save his friend my cousin & his friend involved in the fight. Then all were came to room & involved in their daily routine. That guy was logged a FIR with the help of 3 vehicle recorded by petrol pump staff & false medical report & many false charges such as robbery etc. Then police started searching him & his friends. My cousin & his friend were even don't know the matter. when they came to know already a warrant issued against them. Then they were applied for bail in high court & surrendered at district court & got the bail. After that then all gone to that guys house for a mutual with the help of one parent. The guy come with a rod & started hitting to them. They all stood quietly as they gone their for close the matter. After that nothing positive happened till date. whenever lawyer calls they have to come to court. Now all are doing jobs in private sectors. One of them married & now a father on a 2 yrs old kid. He is a single son & having responsibilities of his parents, wife & son. Income is less & responsibilities is more. He got many offers for job in abroad but denied due to this case. Now scenario is they all are mentally disturbed & physiologically depressed. Day by day they became weak. Now one of them need to go to abroad for his official work. So can he get a passport for it. If yes kindly tell the process & please show the path for the case to close permanently so that they can begin a new life. They are loosing hope as well as life coz they have their families & responsibilities & don't want to leave them in dark. Please Help...
