In what ways has traditional/informal mechanism contributed to formal justice mechanism?

Traditional or informal justice mechanisms have significantly contributed to formal justice mechanisms by providing accessible and culturally relevant dispute resolution, especially in areas where formal systems are weak or mistrusted. They often handle a large volume of minor disputes, reducing the caseload for formal courts. Furthermore, informal mechanisms can offer restorative justice approaches, focusing on reconciliation and community harmony, which can complement or even inform formal sentencing and rehabilitation efforts. They also preserve local customs and norms, which can sometimes be integrated into formal legal frameworks, making justice more culturally appropriate.
