Permanent exemption

I wonder why have you not enquired such information from your lawyer? as for NBWs, the same can be recalled by the court ordering them. 

if you have a just and a genuine reason then the court shall not make a prejudical order against you. if court, in its discretion, chooses not to allow permanent exemption, on that day itself, i suppose the NBW shall not be issued against you. however, court may reprimand seeking your presence on the next date, on which date, you will HAVE to be there. 

Thanks for your advice and attention. My lawyer is quite vague in answering and I have no option but to trust him. Once before, he had sent his junior lawyer for filing exemption but he goofed up and NBW was issued. I stay in Mumbai, the case is in Bangalore and my medical certificate clearly states IT COULD BE FATAL IF I TRAVELED LONG DISTANCE. What I wish to know is that in case NBW is issued, I cannot travel due to cancel the same my medical condition. Is there any other legal remedy I can adopt?
