CY CASE: Imprescriptibility as an Ontological Category: What the Paul Touvier Litigation Did to French Criminal Law

Introduction

Prescription is, in continental criminal law, one of those quiet institutions that everyone accepts without quite knowing why. Time passes, evidence decays, social peace reasserts itself, and the State renounces its right to punish. The 1808 Code d'instruction criminelle fixed the limitation period at twenty years for crimes; the 1958 Code de procédure pénale reproduced the rule almost unchanged. For more than a century and a half, French doctrine treated this temporal extinction as a near-natural feature of criminal repression, to the point that Faustin Hélie could write that prescription belonged to "the necessary order of things".  The Paul Touvier litigation, conducted between 1973 and 1995, broke that quiet consensus. It did so not by abolishing prescription but by forcing French courts to articulate, for the first time in operative terms, what it means for a crime to lie outside the order of time altogether. This article argues that the doctrinal product of the Paul Touvier proceedings is not a chronology of arrests and indictments but a substantive theory of imprescriptibility, and that this theory still structures French criminal law today.

A historical word is unavoidable. Crimes against humanity, it should be recalled, did not exist as such in French criminal law before the statute of 26 December 1964 introduced the category and declared it imprescriptible. The crime is sui generis. It is defined by reference to the Nuremberg Charter and presupposes a connection with a state policy of ideological hegemony directed against an identifiable group; it is not an aggravated form of ordinary murder, and the question its imprescriptibility raises is therefore not only a question of limitation periods but a question about the nature of the crime itself. Paul Touvier, intelligence chief of the Lyon Milice, organised on 29 June 1944 the execution of seven Jewish hostages at Rillieux-la-Pape, in retaliation for the killing of Vichy minister Philippe Henriot (On the facts: J. KAHN, Le procès de Paul Touvier, Plon, 1995, p. 28 et seq.). 

Sentenced to death in absentia in 1946 and 1947, he disappeared into a long clandestine life sustained by the complicity of various Catholic networks, of local society in Savoie and of his own family; he was pardoned by President Pompidou in 1971, and the following year the weekly news magazine L'Express revealed his hiding place in a network of monasteries, which reopened the file on the entirely new ground of crime against humanity (J. DEROGY, "Paul Touvier: la grâce qui fait scandale", L'Express, 5 June 1972). Everything that follows here begins with that change of qualification.

Fig. 1 — L'Express, n° 1978, 2-8 June 1989, cover headline "Paul Touvier : Archives secrètes". The June 1989 scandal crystallised the public perception that archival access itself was a legal question, the same question that French courts were simultaneously deciding about prescription.

I. The conceptual problem: prescription as procedural rule, imprescriptibility as substantive status

Before the Touvier affair, French criminal-law scholarship hesitated on the legal nature of prescription. Two readings competed. The procedural reading, dominant since the early-twentieth-century treatise of R. Garraud (1909), treated the limitation period as a rule of public action: the State extinguishes its own power to prosecute, but the underlying offence remains a wrong (R. GARRAUD, Traité théorique et pratique d'instruction criminelle, Sirey, 1909, t. II, p. 432).

The substantive reading, defended by Merle and Vitu, considered that prescription erases the criminality of the act itself, transforming the perpetrator into a person who, juridically, never committed the crime (R. MERLE et A. VITU, Traité de droit criminel, Cujas, 7e éd., 1997, t. II, n° 51). The distinction is not academic. If prescription is procedural, the legislator may extend or revive a limitation period without violating the principle of non-retroactivity, because the offence already exists in law; if prescription is substantive, any retroactive revival recreates a crime where there was none, in direct violation of Article 8 of the Declaration of 1789 (Article 8 of the Declaration of the Rights of Man and of the Citizen (1789): "The Law shall provide for such punishments only as are strictly and obviously necessary, and no one shall suffer punishment except it be legally inflicted in virtue of a law passed and promulgated before the commission of the offence.").

(Fig. 2 — Philippe Pétain, Chief of the French State, in full uniform. The juridical character of the Vichy regime, and in particular its "policy of ideological hegemony", would become the central interpretive battleground of the Paul Touvier litigation between 1975 and 1992) (source: Wikimedia Commons)

The category of crime against humanity was introduced into French law by a single-article statute of 26 December 1964 declaring that such crimes "by their nature" cannot be prescribed. The statute was adopted to enable French courts to prosecute Nazi and collaborationist crimes after the twenty-year limitation period attached to ordinary crimes by Article 7 of the Code de procédure pénale (Article 7 of the Code de procédure pénale, in its version applicable until the reform of 27 February 2017, provided that public action for crimes was extinguished after ten years from the commission of the offence (twenty years until the loi n° 57-1426 of 31 December 1957 setting the limitation at twenty years for serious crimes; the period varies according to subsequent reforms) was about to expire, and was drafted in deliberate ambiguity to avoid choosing between the procedural and substantive theories of prescription (Loi n° 64-1326 du 26 décembre 1964 tendant à constater l'imprescriptibilité des crimes contre l'humanité, JORF 29 décembre 1964, p. 11788).

The wording is telling. The legislator did not extend a limitation period, did not create an exception to Article 7 of the Code de procédure pénale, did not even cite that article. He affirmed a property of the crime itself. In doing so, he implicitly aligned with the substantive reading for one specific category of offences while leaving the general regime untouched. For a decade, this declaration remained dogmatic. The Touvier affair turned it into operative law.

(Fig. 3 — Letter to the President of the Republic, 15 December 1970 (Archives nationales). 

The grâce campaign for Paul Touvier rested on the argument that "les Tribunaux ont perdu le pouvoir de le punir par l'effet du temps écoulé". The Paul Touvier litigation would, less than four years later, reverse that argument for crimes against humanity; Archives nationales, fonds Présidence de la République (Georges Pompidou), dossier de grâce Paul Touvier, AG/5(2)1073. CA Lyon, ch. acc., 30 mai 1974; CA Chambéry, ch. acc., 11 juillet 1974)

II. The 1975-1976 cassation arrests and the birth of an ontological doctrine

Following the L'Express revelations of 1972, associations of former resistance fighters and victims' families filed civil-party complaints against Paul Touvier in 1973. The investigating judges of Lyon and Chambéry declared themselves incompetent on the ground that the acts had already been adjudicated as collaboration crimes and were prescribed; the indictment chambers confirmed those orders on 30 May and 11 July 1974. The civil parties appealed. The Cour de cassation was thus invited, for the first time, to rule on whether the 1964 statute could revive prosecutions for facts dating back to 1944. When the Chambre criminelle quashed the indictment chambers' orders on 6 February 1975 and 30 June 1976, it could have taken the easy route of treating the 1964 statute as a procedural extension applicable to non-prescribed facts at the date of its entry into force (CA Lyon, ch. acc., 30 mai 1974; CA Chambéry, ch. acc., 11 juillet 1974).

It did not. Instead, the Court held that imprescriptibility was "inherent to the very nature" of crimes against humanity, that this inherence flowed from their recognition by international law since Nuremberg (Article 6(c) of the Charter of the International Military Tribunal annexed to the London Agreement of 8 August 1945 defines crimes against humanity as: "murder, extermination, enslavement, deportation, and other inhumane acts committed against any civilian population, before or during the war; or persecutions on political, racial or religious grounds in execution of or in connection with any crime within the jurisdiction of the Tribunal, whether or not in violation of the domestic law of the country where perpetrated", and that the 1964 statute had merely registered a pre-existing juridical reality.  The reasoning is doctrinally radical. 

By rooting imprescriptibility in the nature of the offence rather than in legislative will, the Court neutralised the objection drawn from Article 8 of the Declaration of 1789: there could be no retroactive revival of a limitation period that had never existed in the first place. The doctrine elaborated in these arrests is what we call ontological, in the sense that imprescriptibility is treated as a property inherent to the crime itself, attached to its very being, not as a procedural exception granted from outside by the legislator. Mireille Delmas-Marty identified this as the moment when French criminal law accepted that "certain crimes inhabit a different temporality" (M. DELMAS-MARTY, "Le crime contre l'humanité, les droits de l'homme et l'irréductible humain", RSC 1994, p. 477, spéc. p. 482).

(Fig. 4 — Handwritten testimony of a diocesan missionary of Chambéry, 4 September 1970 (Archives nationales). 

The ecclesiastical letters of support collected by Mgr Duquaire for the grâce campaign operated within the ordinary-law framework of amnesty and pardon. That framework could not survive the reclassification of Paul Touvier's acts as crimes against humanity)

The construction has two consequences that scholarship has not always disentangled. First, it relocates the source of imprescriptibility from domestic legislation to customary international law, which made the 1964 statute declarative rather than constitutive. Second, and more importantly, it adopts the substantive reading of prescription for crimes against humanity while leaving ordinary offences under the procedural reading. This dualism is the real doctrinal product of the Touvier sequence: French criminal law came to operate, after 1976, with two different theories of time depending on the gravity of the crime, a feature that distinguishes the French regime from systems where prescription is uniformly procedural or uniformly substantive.

(Fig. 5 — Memorial to the seven Jewish hostages executed at Rillieux-la-Pape on 29 June 1944. Naming the victims on stone is, in a sense, what imprescriptibility achieves in law: a refusal to let time dissolve the identity of the crime; source: Wikimedia Commons)

III. The 1992 non-lieu and the temptation of formalism

After the cassation arrests of 1975 and 1976, the file was transferred to the investigating judges of Paris, who began a long instruction; Paul Touvier was finally arrested at the Prieuré Saint-François in Nice on 24 May 1989 and committed to trial. The doctrine survived a serious crisis in April 1992, when the Paris Court of Appeal, applying the Nuremberg requirement that crimes against humanity be committed in connection with a state practising "ideological hegemony", ruled that Vichy France did not satisfy this criterion and that Paul Touvier, acting as a Vichy agent, was therefore beyond reach (CA Paris, ch. acc., 13 avril 1992, D. 1992, jur., p. 369, note P. CHAMBON).

Behind the technical reasoning lies a real doctrinal anxiety. If imprescriptibility is ontological, its conditions of application must be defined with surgical precision, otherwise the category swallows the rule of legality. The Paris court chose precision over substance. The decision was unanimously condemned. Pierre Truche, then Procureur général, spoke of a "juridical alibi for historical denial" (P. TRUCHE, "La notion de crime contre l'humanité", Esprit, mai 1992, p. 67), and Antoine Garapon would later describe the moment as one in which "formal legality and historical truth almost divorced" (A. GARAPON, Des crimes qu'on ne peut ni punir ni pardonner, Odile Jacob, 2002, p. 112). 

The Cour de cassation's response of 27 November 1992 is, in the present authors' view, the most accomplished piece of reasoning in the entire affair (Cass. crim., 27 novembre 1992, Bull. crim. n° 394, JCP 1993, II, 21977, note M. DOBKINE). Without abandoning the ideological-hegemony criterion, the Court reformulated it through the lens of complicity. It sufficed that the accused had knowingly inscribed his act within the criminal enterprise of a state practising such a policy. Paul Touvier had coordinated the selection of the Rillieux victims with the Gestapo; that coordination tied his act to the Nazi project of persecution irrespective of the ideological character of his immediate principal. The construction preserves the ontological theory of imprescriptibility, no lowering of the conceptual threshold, while restoring its operative reach, no immunity for collaborators of authoritarian-but-not-genocidal regimes. It is, in technical terms, an exemplary instance of criminal-law reasoning rescuing itself from its own excess of rigour.

IV. The constitutionalisation that almost did not happen

After the cassation judgment of 27 November 1992, the case was sent to the Cour d'assises des Yvelines, which on 20 April 1994 convicted Paul Touvier of complicity in crimes against humanity, the formal charge being complicity with the Gestapo in the selection and execution of the seven Rillieux victims, and sentenced him to life imprisonment (réclusion criminelle à perpétuité). The Cour de cassation rejected his appeal on 1 June 1995. Paul Touvier died in prison at Fresnes on 17 July 1996, the only Frenchman ever convicted of complicity in crimes against humanity. The verdict and the cassation rejection closed the case but not the doctrinal question (Cour d'assises des Yvelines, 20 avril 1994; Cass. crim., 1er juin 1995, Bull. crim. n° 202). What was the constitutional status of prescription itself? If imprescriptibility for crimes against humanity is justified by the nature of the offence, does prescription for ordinary offences enjoy a corresponding constitutional protection?

The Conseil constitutionnel addressed the question, briefly and obliquely, in its decision of 22 January 1999 on the law authorising ratification of the Rome Statute. It held that "no rule and no principle of constitutional value prohibits the imprescriptibility" of the most serious crimes (Cons. const., 22 janvier 1999, n° 98-408 DC, considérant n° 33).

The Conseil constitutionnel addressed the question, briefly and obliquely, in its decision of 22 January 1999 on the law authorising ratification of the Rome Statute. It held that "no rule and no principle of constitutional value prohibits the imprescriptibility" of the most serious crimes.  The wording is asymmetrical and revealing. The Conseil affirms what is permitted (imprescriptibility) without affirming what might be required (prescription as constitutional principle for the rest). The silence has been read by the Cour de cassation, in its 2011 refusal to transmit four priority constitutional questions (questions prioritaires de constitutionnalité, or QPC) on the prescription of business offences, as authorising it to maintain its own contra legem jurisprudence on limitation periods (Cass. crim., 20 mai 2011, quatre arrêts, Bull. crim. n° 102 et s.).

FYI:

The question prioritaire de constitutionnalité (QPC) is a procedure introduced by the constitutional revision of 23 July 2008 and operational since 1 March 2010, allowing any party to a trial to challenge the conformity of a statutory provision to the rights and freedoms guaranteed by the Constitution. The Conseil d'État and the Cour de cassation filter such questions before transmission to the Conseil constitutionnel.

Julien Gallois rightly observed that the Court, by invoking the 1999 decision in this way, "took the place of the Sages" (« Les Sages » is the customary French expression designating the nine members of the Conseil constitutionnel. See J. GALLOIS, « Prescription de l'action publique : quand la Cour de cassation se prend pour le Conseil constitutionnel », AJ Pénal 2011, p. 516). The point matters here because it shows the long shadow cast by the Touvier affair. The doctrinal dualism born in 1975 has metastasised into a general constitutional incertitude about the value of prescription in French law.

(Fig. 7 — Second page of the verdict of the Cour d'assises des Yvelines, 20 April 1994 (Archives nationales). Question n° 15 reproduces the criterion inherited from Nuremberg: acts committed "dans le cadre d'un plan concerté pour le compte d'un Etat pratiquant une politique d'hégémonie idéologique, en l'occurrence l'Allemagne Nazie". Question n° 16 reformulates Paul Touvier's liability through the complicity construction adopted by the Cour de cassation on 27 November 1992)

(Fig. 8 — Signatures and seals on an international treaty. The ontological theory of imprescriptibility developed by French courts between 1975 and 1992 was validated at European level by the Commission EDH in 1997 on the basis of Article 7 § 2 of the Convention, which opens criminal law to "the general principles of law recognised by civilised nations"; source: Council of Europe)

Conclusion: What remains

What remains, three decades after the verdict in the Touvier affair, is a French criminal law that operates with two regimes of time. One in which prescription extinguishes prosecution as a procedural mercy, and one in which certain crimes are simply withdrawn from the calendar. The Touvier affair did not invent this dualism, but it forced French judges to articulate it, defend it, and bear its full weight. The Papon trial of 1997-1998 confirmed the construction without enriching it (Cour d'assises de la Gironde, 2 avril 1998; Cass. crim., 11 juin 2004, Bull. crim. n° 154), and the European Commission of Human Rights validated the entire sequence by relying on Article 7 § 2 ECHR, which permits punishment for acts criminal "according to the general principles of law recognised by civilised nations", the European version of the ontological theory (Comm. EDH, Touvier c. France, 13 janvier 1997, req. n° 29420/95. Voir également H. LABAYLE, « L'article 7 de la Convention européenne des droits de l'homme et le crime contre l'humanité », RTDH 1997, p. 405). Beyond the conviction of one Milicien, this is the legal legacy of the affair: the French jurisprudence on prescription, settled after the Touvier affair and reaffirmed after Papon, has installed at the heart of French criminal law a temporal dualism that no later reform has dared to undo.
