Demolition

Learned experts, I am owner of a building. The building is of very old construction and due to recurrent rain one corner of the building has collapsed. We have some tenants in the building, they come under Delhi rent control Act. We filled a case in the court of ARC to seek reconstruction of the building and thereafter give the tenants the premises back. The case is still pending. In the mean while the corner of the building has collapsed. My query is can I seek approval from the MCD to demolish the building when the case is still pending? Or will I have to withdraw the case before I approach the MCD?
