This is an emergency repair now, and I am sure that a law enacted in 1847, before the advent of the combustion engine, could not be "reasonable" as classed by the lawyers and therefore cannot be enforced in 2008.
I am sure common sense must prevail, and what makes Maria's neighboughs house sepecial? This act must still cover all / most of GB if it really hasn't been superceeded by later Acts regarding Motor propelled vehicles, and would result in no motorist being able to maintain their motor vehicle outside their own house. That is frankly abursed and totally unreasonable so surely cannot be enforced. :-/ :-/
In addition James are you sure this would still fall within Criminal Law and not Civil Law in 2008? :-/ :-/
Sorry Lizzie, but if there is an Act of Parliament that makes it a crime then it is dealt with by the criminal system. Even a stupid 1847 law like this. The police will only respond to contravention of criminal law.
If your deeds say you can't repair cars on your property (many do) then that would be dealt with by civil law. Police can be involved in civil action, but they usually only go along to keep the peace.
Common law allows people to get redress for actions that aren't covered by the above. People who claim damages for an accident negligently caused do so under common law.
Tort law is the law that would allow James to sue for damage of reputation if his neighbour said something out of order in front of a witness (slander) or wrote and published the same (libel).
Tort law is the one that our admins/mods have to be very careful with, because they can be held responsible for libel posted by any member.
Unfortunately, virtually none of it is based on common sense.
Sorry if this is patronising, but I thought an explanation would help.
