Louisiana Law

Yes. The US Supreme Court is a valid path for appeal even from Lousiania. There isn't much left in LA that is based on the Napoleonic code though. For most issues they've converted over to the English Common Law system. All commerce within the state now follows the Uniform Commercial Code that the other states all use.

Thanks, fishin'. (A deeper look should have given me the same answer, since the Code Napoleon was strong during Louisiana's formative years only.)

Of course, where there are conflicts between the Code Napoleon and the Bill of Rights (e.g. innocent until proven guilty, etc.), the Bill of Rights prevails.
