So, Louisiana is a bit of an odd-ball state in that it observes civil law (Napoleonic law). The big difference between common law and civil law is that in civil law, the judge is expected to base his choice on his interpretation of the law, and not based on the decisions made by previous judges in other similar court cases.

So, the question is: when a court case is decided in Louisiana, can it establish precedent in other states that follow common law?
