The ID Act establishes three dispute resolution bodies: Labour Courts (for matters in the Second Schedule), Industrial Tribunals (for matters in the Second and Third Schedules), and National Tribunals (for disputes of national importance). Environmental Tribunals are established under the National Green Tribunal Act, 2010, which is an entirely separate legislation dealing with environmental disputes — they have nothing to do with industrial disputes or labour law.
