I wonder if private parking rules can be enforced by the government?

As an imprsionable young man I watched a cop attempt to cite someone for an traffic inccident that occured on private property. I saw the lawyer, who was the injured party and not getting the ticket warn him off and it stuck. Not sure how that would work today.

Probably not, but perhaps the owner of the lot can impound their cars for disobeying the parking rules and preventing the 'clampers' from driving away from the premises. I'm not familiar with how things work in Britain, so who knows.
