State of Maharashtra v. Ramdas Shrinivas Nayak & Anr.(1982) 2 SCC 463 where, in para 4, a question arose qua a concession made in the High Court, while contending the matter before Supreme Court. It is in that context that it was observed that this Court would not launch into an inquiry as to what transpired in the High Court:
“4. ………It is simply not done. Public Policy bars us. Judicial decorum restrains us. Matters of judicial record are unquestionable. They are not open to doubt. Judges cannot be dragged into the arena. “Judgments cannot be treated as mere counters in the game of litigation” (Per Lord Atkinson in Somasundaram Chetty v. Subramanian Chetty, AIR 1926 PC 136). We are bound to accept the statement of the Judges recorded in their judgment, as to what transpired in court. We cannot allow the statement of the judges to be contradicted by statements at the Bar or by affidavit and other evidence. If the judges say in their judgment that something was done, said or admitted before them, that has to be the last word on the subject.
The principle is well settled that statements of fact as to what transpired at the hearing, recorded in the judgment of the court, are conclusive of the facts so stated and no one can contradict such statements by affidavit or other evidence. If a party thinks that the happenings in court have been wrongly recorded in a judgment, it is incumbent upon the party, while the matter is still fresh in the minds of the judges, to call attention of the very judges who have made the record to the fact that the statement made with regard to his conduct was a statement that had been made in error (Per Lord Buckmaster in Madhu Sudan Chowdhri v. Chandrabati Chowdhrain, AIR 1917 PC 30).
That is the only way to have the record corrected. If no such step is taken, the matter must necessarily end there. of course a party may resile and an Appellate Court may permit him in rare and appropriate cases to resile from a concession on the ground that the concession was made on a wrong appreciation of the law and had led to gross injustice; but, he may not call in question the very fact of making the concession as recorded in the judgment.”
The aforesaid paragraph was, once again, extracted with approval in Y. Sleebachen & Ors. v. State of Tamil Nadu through Superintending Engineer Water Resources Organisation/Public Works Department & Anr.(2015) 5 SCC 747
