In its judgment in the Videla case in 1994, Chile’s Appeal Court of Santiago held that common Article 3 of the 1949 Geneva Conventions obliged parties to non-international armed conflicts “to extend humanitarian treatment to persons taking no active part in the hostilities or who have placed themselves hors de combat for various reasons”.

[W]ithout any doubt, the 1949 Geneva Conventions are in force … and oblige State parties in case of armed conflict not of an international character occurring within their territory, which is exactly the situation in Chile during the period of 12 September 1973 and 11 March 1975, to treat humanely … opponents who have laid down their arms, … prohibiting in particular at any time and any place a) violence to life and person, and b) outrages upon personal dignity.
