If you are in possession of property, police cannot come and throw you out from possession unless there is an order from court.
If someone forcefully throws you out of property, the Magistrate (Criminal Court) can pass immediate orders under Sec.145 to put you back in possession.
This provision is to ensure that no one takes law in their own hands to dispossess someone from property.
Civil disputes of property are different. Here, Civil Court decides such disputes.
