Special Provisions
(1) Parliament may by law provide for administrative tribunals to adjudicate disputes over recruitment and service conditions of public servants (Union, State, local authority, or government-controlled corporation). (2) Such a law may establish a Union tribunal and separate State/multi-State tribunals, define their powers (including contempt power), set their procedure, exclude all courts except the Supreme Court's Article 136 jurisdiction, transfer pending cases to them, and include other necessary supplemental provisions. (3) This article overrides any other constitutional provision or law.
This is the constitutional basis for Administrative Tribunals (like the Central Administrative Tribunal, CAT) - specialised bodies created specifically to handle government employee service disputes (like disciplinary actions, promotions, and recruitment issues) instead of those cases going through ordinary High Courts, with only the Supreme Court's special-leave-appeal power remaining as a further check.
This is why a government employee's dispute over a disciplinary action or denied promotion typically goes first to the Central Administrative Tribunal, not directly to a High Court - a faster, more specialised forum for these specific kinds of service disputes.
