19. Laying down the broad parameters within which the High Court ought to exercise its powers under Article 226/227 of the Constitution of India and matters relating to disciplinary proceedings, a two-Judge Bench of this Court in Union of India and Others v. P. Gunasekaran, (2015) 2 SCC 610 held thus:

“12. Despite the well-settled position, it is painfully disturbing to note that the High Court has acted as an appellate authority in the disciplinary proceedings, reappreciating even the evidence before the enquiry officer. The finding on Charge I was accepted by the disciplinary authority and was also endorsed by the Central Administrative Tribunal. In disciplinary proceedings, the High Court is not and cannot act as a second court of first appeal. The High Court, in exercise of its powers under Articles 226/227 of the Constitution of India, shall not venture into reappreciation of the evidence. The High Court can only see whether:

(a) the enquiry is held by a competent authority;

(b) the enquiry is held according to the procedure prescribed in that behalf;

(c) there is violation of the principles of natural justice in conducting the proceedings;

(d) the authorities have disabled themselves from reaching a fair conclusion by some considerations extraneous to the evidence and merits of the case;

(e) the authorities have allowed themselves to be influenced by irrelevant or extraneous considerations;

(f) the conclusion, on the very face of it, is so wholly arbitrary and capricious that no reasonable person could ever have arrived at such conclusion;

(g) the disciplinary authority had erroneously failed to admit the admissible and material evidence;

(h) the disciplinary authority had erroneously admitted inadmissible evidence which influenced the finding;

(i) the finding of fact is based on no evidence.

13. Under Articles 226/227 of the Constitution of India, the High Court shall not:

(i) reappreciate the evidence;

(ii) interfere with the conclusions in the enquiry, in case the same has been conducted in accordance with law;

(iii) go into the adequacy of the evidence;

(iv) go into the reliability of the evidence;

(v) interfere, if there be some legal evidence on which findings can be based.

(vi) correct the error of fact however grave it may appear to be;

(vii) go into the proportionality of punishment unless it shocks its conscience.”

22. To sum up the legal position, being fact-finding authorities, both the Disciplinary Authority and the Appellate Authority are vested with the exclusive power to examine the evidence forming part of the inquiry report. On finding the evidence to be adequate and reliable during the departmental inquiry, the Disciplinary Authority has the discretion to impose appropriate punishment on the delinquent employee keeping in mind the gravity of the misconduct. However, in exercise of powers of judicial review, the High Court or for that matter, the Tribunal cannot ordinarily reappreciate the evidence to arrive at its own conclusion in respect of the penalty imposed unless and until the punishment imposed is so disproportionate to the offence that it would shock the conscience of the High Court/Tribunal or is found to be flawed for other reasons, as enumerated in P. Gunasekaran (supra). If the punishment imposed on the delinquent employee is such that shocks the conscience of the High Court or the Tribunal, then the Disciplinary/Appellate Authority may be called upon to re-consider the penalty imposed. Only in exceptional circumstances, which need to be mentioned, should the High Court/Tribunal decide to impose appropriate punishment by itself, on offering cogent reasons therefor.
