According to Serbian authors T. O. Oraovac and S. S. Djurić, the code also served as the base of the Kanun of Albanian nobleman Leka Dukagjini (1410–1481), a set of customary laws in northern Albania that existed until the 20th century. Noel Malcolm suggests that an article in Dušan's Code was an early attempt to clamp down on the self-administered customary law of the mountains, as later codified in the Kanun of Lek Dukagjin, and if so, this would be the earliest evidence that such customary law was in effect. Despite the similarities historians agree that the Code of Leke Dukagjini is not the same as Dusans Code and that such conclusions are "far-fetched". When the Turkish invaders conquered the medieval Serbian state many customary laws of social life amongst the Balkan peoples were brought back to use, this included the Albanians.
