• How to evict my late tenant's sons from dilapidated building?

When we ask our late tenant sons to vacate the shop, they ask for time and in that time they actually file a case against us in the Lower court, we won the case after a long time, then we filed a case to evict them wen won that case too, but they appeal to the High Court when they were supposed to vacate the shop and obtained an interim injunction, High Court telling us to maintain the status quo, pending further orders and it's been a year, since then, there has been no progress in the case and it still pending. http://hc.tap.nic.in/csis/MainInfo.jsp?mtype=CRP&mno=1270&year=2015


Then, we received a notice from the Municipal Corporation saying that our building is dilapidated and they are going to pull down the building, I was okay with that and willing to comply and vacated the First Floor and when the Municipal Corporation employs turned up, My late tenant's sons show them the interim order of the High Court and they went away and after that my Late tenant's son have filed a case against Municipal Corporation and us not to demolish the old building and obtained a Show Cause notice. In that notice, the court asks us to appear and tell us our side of the story, what do you think we should do. My Lawyer suggests to take the photos of the building to show its condition. How to make my case stronger, how to win this case in the Next Hearing, need help. 

My Late Tenant's son raise two major points in his affidavit which aids him in getting an interim order against Municipal Corporation and us. First is: Municipal Corporation didn't issue them any notice quoted some act of Indian constitution, based on that occupant should get a notice. But, I think notice to owner is enough in case of dilapidated building http://www.deccanchro nicle.com/150226/nation-curren t-affairs/article/hyderabad- high-court-tenants-need-no- notice.

Second point he raised was: That we have colluded with Municipal Corporation to evict him from premises. This it completely false. 
My question is, what i should do or say in the High court, Is there way to to evict them and demolish the old building, immediately or in some days?

By the way, Can I give this house to my son and make him the owner of this building, will this help me to vacate My tenant's late sons. My Lawyers says no, I cannot do it since they case is going on in High Court. I  really disliked the Law, giving my late tenant's sons so many chances. They are not my real tenants their father was and his contract with me was finished in his lifetime, now, they lost cases in lower courts, twice! Come on, The High Court should have dismissed their appeal, they are in profit since they are making money, I cannot evict them, though, I tried by bringing the Bailiff Twice but they closed the shop when he came, and the Bailiff cannot break the lock and throw their stuff out, this is just annoying as hell!

Does Tenancy cease to exist at the death of the Tenant?Model Tenancy Act 2015 , has this ACT approved?
 
Rent agreement transfer in case of tenant’s death:  What if a tenant dies while the rent agreement is still in force? According to the draft, the agreement comes to an end as soon as the tenant dies. However, if the person has been living at the rented accommodation with his family, the tenancy rights would pass on to his wife or children. https://www.proptiger.com/guide/post/10-things-landlord-renters-must-know-about-model-tenancy-act
