Injunction on property

Hi we bought a residential property in chennai no 1 commercial road. we converted that property as commercial space and tax for the same also have been paid. a co owner in the same building had file 3 injunction on the property which is 1) should not use the common space 2) should not lease or rent out the property 3) should not have a opening in the road face of the building claiming that this building is residential apartment an commercial activity will give disturbance. The one who filed case is a advocate and he made his friend to appear for him. Mainly they cant get 3 injunction at one time for a property and we lent the space for a tenant before he filed injunction. This happened 3 years before and those ppl have never came for argument and talks have been going out of the court for mutual settlements. now we had let the space for another company for rent. These ppl now threatening us about court contempt that we lent out the space to other ppl while the injunction is still on. We had talks with his lawyer well before that we going to lent out since its our bread winner income. He tricked us to do against the Injunction and demanding to give 30lakhs to vacate those injunction. We have no such money nor have the capacity to face an contempt case. Kindly give advise on this sir
