I don't remember the lawsuit's name off the top of my head, but I believe it occurred in the 90's. It has since become famous in the U.S. as an example of a ridiculous, frivolous lawsuit (edit: see Daxy's ridiculous, unfounded post above as an example), but that reputation is completely unjustified.
Sorry, I assumed you were actually referencing that particular case, not a hypothetical. Didn't mean to bite your head off.
