after every state adopted the English common law

49 of the states adopted English common law. Louisiana's Constitution is based on codified, or Roman law (sometimes erroneously called French law.)

[Publius Valerius]

Yes, I suppose I should have been more clear: every state that was around at the time of the ratification of the Constitution.

But you're right--civil law rules in LA.

"49 of the states adopted English common law. Louisiana's Constitution is based on codified, or Roman law (sometimes erroneously called French law.)"

Why do you say it was erroneously called French law? It was French, as well as Spanish, which I believe were derived from Roman Law.

[Republican Wildcat]

That's interesting. I have read before that Louisiana was based on "Napoleonic Code" originating from the time the territory was controlled by France.
