(2.) Roma locuta est; causa finita est. Rome has spoken, the cause is ended. Rome spoke through her laws. One of the pillars of Roman law is contained in the maxim res judicata pro veritate accipitur (a thing adjudicated is received as the truth). This maxim of Roman law is based upon two other fundamental maxims of Roman law, namely, interest reipublicae ut sit finis litium (it concerns the State that there be an end to law suits) and nemo debet bis vexari pro una at eadem causa (no man should be vexed twice over for the same cause). Indeed, that this maxim is almost universal in all ancient laws, including ancient Hindu texts, was discussed by Sir Lawrence Jenkins in Sheoparsan Singh v. Ramnandan Singh, 1916 AIR(PC) 78 at 80-81 as follows: "There has been much discussion at the Bar as to the application of the plea of res judicata as a bar to this suit. In the view their Lordships take, the case has not reached the stage at which an examination of this plea and this discussion would become relevant. But in view of the arguments addressed to them, their Lordships desire to emphasise that the rule of res judicata, while founded on ancient precedent, is dictated by a wisdom which is for all time. "It has been well said," declared Lord Coke, "interest reipublicae ut sit finis litium, otherwise great oppression might be done under colour and pretence of law": (6 Coke, 9a). Though, the rule of the Code may be traced to an English source, it embodies a doctrine in no way opposed to the spirit of the law as expounded by the Hindu commentators. Vijnanesvara and Nilakantha include the plea of a former judgment among those allowed by law, each citing for this purpose the text of Katyayana, who describes the plea thus: "If a person though defeated at law sue again he should be answered, 'You were defeated formerly'. This is called the plea of former judgment." (See "The Mitakshara (Vyavahara)" Bk. II, ch. i, edited by J.R. Gharpure, p. 14, and "The Mayuka," Ch. I., sec. 1, p. 11 of Mandlik's edition.) And so the application of the rule by the Courts in India should be influenced by no technical considerations of form, but by matter of substance within the limits allowed by law."
(3.) This Court in Daryao and others v. State of U.P. and others, 1962 1 SCR 574 at 583-584, put it very well when it said: "In considering the essential elements of res judicata one inevitably harks back to the judgment of Sir William De Grey (afterwards Lord Walsingham) in the leading Duchess of Kingston's case [2 Smith Lead. Cas. 13th Ed. pp. 644, 645]. Said William De Grey, (afterwards Lord Walsingham) "from the variety of cases relative to judgments being given in evidence in civil suits, these two deductions seem to follow as generally true: First, that the judgment of a court of concurrent jurisdiction, directly upon the point, is as a plea, a bar, or as evidence, conclusive between the same parties, upon the same matter, directly in question in another court; Secondly, that the judgment of a court of exclusive jurisdiction, directly upon the point, is in like manner conclusive upon the same matter, between the same parties, coming incidentally in question in another court for a different purpose". As has been observed by Halsbury, "the doctrine of res judicata is not a technical doctrine applicable only to records; it is a fundamental doctrine of all courts that there must be an end of litigation [Halsbury's Laws of England, 3rd Ed., Vol. 15, para. 357, p. 185]". Halsbury also adds that the doctrine applies equally in all courts, and it is immaterial in what court the former proceeding was taken, provided only that it was a Court of competent jurisdiction, or what form the proceeding took, provided it was really for the same cause (p. 187, paragraph 362). "Res judicata", it is observed in Corpus Juris, "is a rule of universal law pervading every well regulated system of jurisprudence, and is put upon two grounds, embodied in various maxims of the common law; the one, public policy and necessity, which makes it to the interest of the State that there should be an end to litigation - interest republicae ut sit finis litium; the other, the hardship on the individual that he should be vexed twice for the same cause - nemo debet bis vexari pro eadem causa" [Corpus Juris, Vol. 34, p. 743]. In this sense the recognised basis of the rule of res judicata is different from that of technical estoppel. "Estoppel rests on equitable principles and res judicata rests on maxims which are taken from the Roman Law" [Ibid p. 745]. Therefore, the argument that res judicata is a technical rule and as such is irrelevant in dealing with petitions under Article 32 cannot be accepted.";
