Husband Refusing to receive court orders and staying in Dubai

Hi, My sister got married on 2017. The guy took my sister for 3 months to Dubai and then they all started creating problems like asking more dowry, giving mental torture etc., They asked my sister to move with us since they wanted to attend some marriage function in Srilanka. All these happened within 6 months time. After she moved, there is no contact from them. Her husband also deserted her. We tried to contact them through Jamath. That also wasted. On 2018, they sent one notice asking my sister to apologize publically in Jamath and to leave my family. Else she would face the consequences. We did reply to that notice and again they didn't make any move. My sister filed a family court petition asking for a solution to join with her husband. Till now they didn't receive any court order including the foreign notices. That guy made a separate case asking for divorce in his district court. We don't know this matter as we moved out of the address. Eventually the court didn't give any approval for his IA petitions. This case details came to our notice when they tried to sneak through Jamath to get divorce from my sister again. Now that case also moved to the family court. We believed that at least he will respond if we move the case to our place. But still that guy is adamant and we don't know what to do further. Please provide me any help for the below matters: 1. Is there any way to deport that guy from dubai to India? 2. Is there any way to make him pay the maintenance and the expenses for the marriage and case? (FYI she filed a MC case before 3 months) 3. For all these years he turned deaf ears to court petitions and we are just wandering between the courts. My sister got almost fedup with this guy who doesn't even want to tell whether he wanted to live with her or not. Is there any way to take criminal action against him and his family? I can't see my sister suffering with this matter for years.
