³ Le juge qui refusera de juger sous prétexte du silence, de l'obscurité ou de l'insuffisance de la loi, pourra être poursuivi comme coupable de déni de justice” (art. 4). See on the subject: Norman, J., L'office du juge et la contestation (Paris, 1965).Google Scholar Boileux, commenting on this article, observes among others: “Let us remark here that the judge appointed to solve a litigation must perforce pronounce (doit nécessairement prononcer); he is even forbidden to suspend sentence in order to consult with the legislator on the meaning of the law: such a consultation (référé) would amount to a denial of justice, and denial of justice is punished by a fine…”; (from Commentaire sur le Code Napoléon (Paris, 1866) vol. 1 p. 28); see also Bonnier, E., Traité Théorique et Pratique des Preuves en Droit Civil et en Droit Criminel (Paris, 1873) 49Google Scholaret seq., including a discussion of the principle actore non probante reus absolvitur as an obstacle to non liquet.

The decision was ultimately upheld by the Supreme Court: see Harnon, E., Law of Evidence (Jerusalem, 1970, in Hebrew) 188–190.Google Scholar Such a decision has the validity of res iudicata. In some recent enactments, however (such as the Civil Procedure Rules, r. 490, (1963) K.T. no. 1477), a distinction is made between the rejection of a plaintiff's claims on the merits, effective as res iudicata, and the mere striking out of the action which does not preclude the filing of a new action on the same cause; see on this subject Ginossar, S., “Renewal of Actions” in Studies in Law, Scripta Hierosolymitana (Jerusalem, Magnes Press, 1958) Vol. 5, pp. 48Google Scholaret seq.

²⁷ J. Stone, Legal Controls… op. cit. supra n. 20 at p. 153 et seq.; see also n. 1, p. 153, stressing the difference between non liquet in Roman Law and in International law: “The modern meaning of the term is thus different from that in Roman law, where the term ‘non lique’ originated. It there referred either to the mere deferment of a decision pending further information, or the personal non-participation of a particular member of the tribunal in the decision. Though these situations could arise internationally, the situation debated on the modern ‘non liquet’ involves a full non possumus of the tribunal, the refusal to decide being both absolute and institutional.” On the problem as it arose in Roman law see infra, text at n. 34 et seq.

³⁰ Ibid., p. 1 et seq.; we also quote n.l, p. 6: “This does not arise from ‘juridical megalomania’ (juristischer Grössenwahn), as was the opinion of Kantorowitz (Flavius, Gnaeus, Der Kampf um die Rechtswissenschaft (Heidelberg, 1906) 17)Google Scholar but from the practical necessity that each one must, in a certain way, coordinate his own behaviour with that of others. This is the essential basis or concept of law. A system of law which, though able to solve some problems in life, should prove itself incapable of solving all others would nullify itself ipso facto, since it fails in its primary function—that of creating order among human beings (hominis ad hominem proportio—the relation of man to man). Only in this practical sense is a jurist obliged to reach a conclusion regarding each question presented him; a line of demarcation between the lawful and the unlawful, between the exigible and the non-exigible, must be established; otherwise such a distinction will in some way be delineated in the facts, rebus ipsis dictantibus et humants necessitatibus (the facts themselves and human necessities being decisive); and the jurist must in the end recognize it. If the biologist, the philologist and the historian confess their inability to solve all the problems pertaining to their respective sciences, this is not because they are more modest than the jurist (as Kantorowitz, loc. cit., hints), but rather because limits and doubts in theoretical knowledge do not suspend the progress of life. When instead, as in legal science, one seeks to regulate human actions effectively, science merges to some extent with the necessarily continuous course of these actions, and, therefore, cannot fail to accompany them with its judgments, which are, however, only of immediate practical value. While it is indeed true that in its theoretical range jurisprudence also has doubtful points, its age-old problems, and can ad infinitum doctrinally debate even res iudicatae; nevertheless each new controversy, as it arises, although it may involve points scientifically unclarified, bears with it the concomitant necessity of the issuance of a judgment that will be definite and certain and which will have practical finality”.

⁴⁸ “If a defendant was sued maliciously, the plaintiff having full knowledge that his claim was unjust, and was absolved, he could bring an action against his adversary for a tenth of the amount claimed in the former trial, but he had to prove that the latter acted calumniae causa”. Sic Berger, A., Encyclopaedic Dictionary op. cit., at p. 520.Google Scholar It may be noted here that recently it has become more and more vital to introduce norms of loyalty and integrity of the parties and their legal representatives in court, “and especially the introduction of a pledge of loyalty (obbligo di verità) by the party (and his representative) not to adduce facts it knows to be false, and not to contest facts (adduced by the adversary) it knows to be true. A pledge of this sort was known to the classical Roman tribunal, together with institutions aimed at preventing acts of reciprocal deception and cheating (Cappelletti, M., Processo e Ideologie (Bologna, 1969) 216Google Scholaret seq.: nevertheless, there remain other serious dangers, as noted by Redenti, E., “L'Umanità nel Nuovo Processo Civile” (1941) 18 Rivista di Diritto Processuale Civile 30Google Scholaret seq.; and Calamandrei, P., Opere Giuridiche (Napoli, 1966) 306Google Scholaret seq. and 556 et seq.; see also Winfield, , The History of Conspiracy and Abuse of Legal Procedure (1921)Google Scholar; Ginossar, S., “Nuisance Between Litigants” (1970) 2 Mishpatim 221Google Scholaret seq. and 553 et seq.

Levy, “La Formation de la Théorie Romaine des Preuves” op. cit. at p. 420 n. 10, when he affirms that Gellius was unable to find (in the law) a solution to the problem of burden of proof, and was forced to seek it in a purely pragmatical work (one of Cato's addresses). In fact Gellius was conscious that what his advisors suggested was the general prin ciple, which however did not satisfy his conscience in that specific case; on this see mainly G. Pugliese, “L'Onere della Prova” op. cit. at p. 356 and n. 6.

⁵² From the episode it appears that Gellius, not Favorinus, had been appointed index, and that the decision sibi non liquere was that of Gellius—not of Favorinus, contrary to what Volterra, E. writes (Istituzioni di Diritto Romano (Roma, 1961) 235)Google Scholar“ciò risulta da un episodio narrato da Gellio, Noc.

A powerful man whose integrity was beyond suspicion, could well judge regardless of the strict norms of the law, because no one would have dared to suspect him of having acted by self-interest or bias”.

⁵⁴ See G. Pugliese: Il Processo Civile Romano, op. cit., vol. 2, p. 253: the obligation to judge did not necessarily entail the obligation to actually solve the controversy.

⁵⁵ Nevertheless, see Schulz, F.: Classical Roman Law (Oxford, 1951) 14Google Scholar: “In civil, unlike criminal procedure it is not permissible to pronounce non liquet”. Schulz refers to the Römische Strafrecht by Mommsen, in which, however, the author does not deal with the question of non liquet in the framework of civil procedure. Against Schulz's opinion, and in favour of Buckland's and Jolowicz's, see Duff: “Non Liquet” op. cit. supra n. 44.

⁵⁷ It may be useful to remark that Pothier introduced Gellius' passage in his Pandette, affirming explicitly: “nevertheless, if the given Judges did not grasp the question of the case, they swore that it was not clear to them (sibi non liquere)” (sub. D. 5.1.79.1).

⁶⁴ This principle is also found in Jewish law, where, however, contrary to the Roman system, it is provided that should one of the judges wish to abstain, a substitute must act in his place, in order to avoid a reduction of the judging college: see Mishna Sanhedrin, III, 6 and V, 5 and Rashi's commentary to the Sanhedrin treatise, 29 a.

⁷² “If any judge should suppose that a case ought to be referred to Us, he must pronounce no decision, but rather he shall consult Our Wisdom on the point on which he supposes that there is some doubt; but if he should render a decision, he must not thereafter deter litigants from appealing therefrom by promising to refer the matter to Us. Given on the fourth day before the ides of February at Sirmium in the year of the fifth consulship of Constantine Augustus and the consulship of Licinius Caesar. February 10, 319; February 7, 318”.

⁷³ “…to examine the case with the utmost care and to pronounce in accordance with what appears to them fair and legitimate”. It will be recalled that around that time a theory of evidence was being formulated, providing the judge with additional criteria of judgment. On this point see Archi, G.

This is especially evident in the history of trial per relationem: regulated by Justinian in 529 (Cod. 1, 14, 12), it was entirely abolished after the codification by Novella 125”.

⁷⁸ On this point see P. Shifman, op. cit., p. 14 et seq., where the author remarks that in the Middle Ages, due primarily to the influence of Rabbenu Asher (Rosh), there came a change in directives. If the judge has good reason to suspect fraud on the part of the plaintiff, he has to decide the case in favour of the defendant; and conversely, if his suspicions fall upon the defendant, he must pronounce in favour of the plaintiff (note the similarity with Gellius' problem, reported supra) Finally, a new principle makes its appearance, namely that if the judge deems the case to be objectively doubtful, and such that presumably another judge would reach the same conclusion, he must attempt to bring the parties to a compromise. Not directly relevant to our problem is the duty of the court to abstain from judgment when there is reason to think that later events may disprove the justice of the sentence: in such exceptional cases the legal position is to be kept in abeyance subject to subsequent evidence; on this point too, see P. Shifman, op. cit. at p. 15.
