"Common law is a huge mass of improvised patches accumulated over countless generations. It grew beyond capacity of an intelligent person to grasp and even lawyers cannot understand it completely. That is why expensive lawyers can be so much better and that is why common law is perfect for the lawyers."
Wake up and smell the cajun hot sauce. Louisiana law is based on Napoleonic code. It sucks.
It is extremely expensive. Try getting a divorce here in Louisiana - people get stuck in the divorce system for YEARS.
Civil law only means what the 'civilians' say it means. Funnily enough, often the very people writing the laws are the ones interpreting it.
But wasn't it frozen in time after Louisiana became part of USA? Codex law has to rewritten once a while.
