Divorce on desertion

My friend married in 2008. His wife left her husband’s house after four days of marriage. After marriage, she had gone to Patna to continue her MBA study. My friend was also studying and he had also gone to pursue his master. Both side continued meeting till 2009 and after that she refused to meet her husband. My friend field RCR in 2013 and got the decree Ex-parte in August 2014. Soon after RCR decree my friend filed divorce on the ground of desertion in Aug 2014. Initially she did not turned-up in court but after notification in newspaper she appeared in court. My friend is a NRI. Court asked her, if she is ready to go with her husband then court will ask her husband to come in court. She refused to go with her husband. Court asked for mutual settlement but her father did not agree. Her father requested court to cancel the divorce case because, this case should be filed only after one year of RCR decree. But, court refused to cancel the divorce and put a fine of RSXXX on her father. Now this case has gone into contest. My friend’s wife told over phone in past to my friend that she is in love with someone else and wants to marry the guy. My friend recorded this phone conversation on his mobile. My friend requested her for mutual cosset divorce but she refused. She is suspected to be in relation with the second man (But no proof). Her father is very influential man and her brother is a judge. My friend is from a modest family. Currently witness from my frinds side is ongoing. Can someone advise what to do to get divorce soon. Its more that 5 years since she deserted.
