I think we brushed on this a little in the past, but what about laws of giving an eviction notice.
A landlord has to give a written notice of say 60 days to evict WITHOUT cause. Then the tenant has a right to a defense. If the case is won (by the landlord) in court you still dont have a right to physically move someone out of your property. A court judgement must be given to local law enforcement who then gives a time frame to leave the property. Also there are many laws protecting evicting mentally incompetent.
