Lok-Adalat is a forum for alternative dispute resolution in India.
It is presided over by a sitting or retired judicial officer as the Chairman, along with other members.
Its main purpose is to settle disputes amicably and quickly, avoiding lengthy court procedures.
Other options:
Debt Recovery Tribunal (DRT) – presided over by a Presiding Officer (judicial/technical), not exactly a Lok-Adalat-type structure.
Co-operative Ombudsman – deals with cooperative societies but not headed by judicial officers.
So the answer is clearly Lok-Adalat.
