My brother’s wife is harassing the complete family

My brother’s wife is harassing the complete family by filling the false complaints, let me brief the little background: 1. Married in 2010, left his home in 2011 and started living with her parents than filled DV case & complaints in women cell. 2. She went to his office premises and create nuisance consequently company had issued termination letter to my brother and eventually he lost his job 3. My brother filled divorce petition in 2012 but in 2013, after consoling by Judge she returned to in-laws house but behavior was unchanged. 4. This time, she started sending mails to my brothers new company stating that she wanted half of his salary as her husband did not provide her food and clothes. HR told her to stopped such mails as this is your internal matter but she did not stopped. He again got the warning letter and leave this company 5. In 2014, she again left his house, this time her brother and mother came to her in-laws house and started fighting with them, his father got severe injuries.She again filled DV case & false complaints to police & women cell that she is being tortured.(We also reported to police station about this incident, and had medical done also) 6. Divorce case again filled by us in 2014 and she got the interim maintenance in DV case of INR 35,000 (at that time my brother was earning INR 65,000). 7. We filled the case in session court to reduce the maintenance amount even Salary slips were also showed to Judges but they refused our plea by stating that she deserves this amount 8. We loss the divorce case in 2016, and currently its pending in high court. 9. They always make excuses in DV case to make more amount of maintainance and still in process from 2014.Even judges don't say anything even they know they are doing this to get another date. 10. Till now she had looted more than 17 lakh from us on the name of maintenance. Every 2-3 month she filled false complaints/case either in police station or in women cell just to torture us. His mother got brain hemorrhage and paralysis and bedridden from last 3 years. 11. We are almost spent 25 lakh rupees on court proceedings and maintenance amount and almost verge to bankruptcy. she is not giving divorce either. please suggest us what should we do now. we almost lost all hopes by Seeing the working way of judiciary. My brother life has totally ruined from the day he married to this women. In the 8 year of marriage, they hardly lived 15 months together & living seprately from more than 4.5 years.
