Lakengulf took the question on and gives the opinion that corporations can be given the right to create & enforce policies that are at variance with the law. In this case, the law says it is OK for corporations to prohibit guns on their premises even though the law is based on the right of self-defense. With that reasoning, they can't be held liable for injuries sustained on their property even if they prevented the victim from defending themselves adequately.
But I still can't think of another example of a law that says that someone (or some corporation) can deny rights granted under law while a customer is on their property. Can someone give me an example of another law that gives corporations the right to make & enforce policies that supercede laws enacted by the state?
