Re Liebeck v Mac Donalds
I am assuming the report at the web site below is a reasonable account .... but if one is to be certain one should read the judgement...however...these sorts of cases are applying the laws know as Torts...Torts predominate feature is that folk owe other folk a duty of care and if someone suffers damage as a result of a failure to exercise that duty of care then the victim can claim damages.
The case appears to turn on the established fact that MacDonalds breached their duty of care by serving coffee unreasonably hot..near boiling which was not common practice for vendors of coffee...anyways here is a link that makes the victim seem less horrid than the various net versions out there.
