Even if you know the details of the Mohan s other buisness or shops ; it will not help you in getting eviction.
Your presumption that case for injuction by Mohan is false.
He has all the right to get injuction and maintain status quo.
To get eviction you have to show genunine reasons of your need which must be superior than the needs of the tanent.
Regarding acceptance of rent ; it is your right to get it till you get actual possession.If the tanent fails to pay rent it will be a solid reason in your facour to get eviction.
Pl also note that for termination of tenancy the notice sent by you is very important. A smart Advocate can fish out admisssions by you and technical faults in favour of the tanent and your whole effort of getting possesion may fail if a wrong notice is given.
Please note that rent laws are loaded in favour of the tanent so unless you have an iron clad case there will be defficulties for you to get posession.
