- The question of whether the Central Administrative Tribunal (CAT) can interfere with the quantum of penalty imposed by the disciplinary authority on the ground of proportionality was extensively examined by the Supreme Court in the case of Union of India vs. Shri Parma Nanda (AIR 1989 SC 1185). - The Supreme Court held in this case that the Tribunal has the power to judicially review the findings of the disciplinary authority and the punishment imposed. However, the Tribunal should not sit as an appellate authority substituting its own view on the penalty. It should only interfere with the quantum of punishment if it is shockingly disproportionate to the misconduct proved or if there is some procedural irregularity leading to miscarriage of justice.
