Hey, sorry for the wait! I was away with no internet. Wartime provisions were covered under the Galactic Constitution, the Galactic Republic’s founding document, as was the Rights of Sentience clause, so it can be assumed that laws relating to civilians and other non-combatants were located in a similar document. The laws do exist, as people have been charged for war crimes under the Republic, but beyond that I cannot find any reference to a Republic document that outlines those laws. As the Imperial Charter is based on the Galactic Constitution, it is possible that those laws remained – likely with modification, as occurred with the Rights of Sentience and many acts surrounding the military and law enforcement. Likewise, I can’t find specifics for the New Republic in canon or legends.
Sorry I couldn’t be more help!
