French Military Courts History

Origins and the Ancien Régime

Military justice in France predates the Revolution. The prévôts des maréchaux exercised criminal jurisdiction over soldiers from the fourteenth century, while the Conseil de guerre emerged as the principal military court under Louis XIV’s Ordonnance militaire de 1665. These early tribunals applied the Code de justice militaire of the Ancien Régime, which distinguished between infractions of military discipline (punished by the Conseil de guerre) and ordinary crimes (punished by civilian courts).

The revolutionary period abolished the old military courts and replaced them with tribunaux militaires organised on the same principles as civilian tribunals. The Code des délits et des peines of 1791 confirmed that military personnel accused of ordinary crimes would be tried by civilian courts, while military offences would be judged by military tribunals.

The Nineteenth Century and the Conseil de Guerre

The Code de justice militaire of 1857 established the definitive structure of French military courts for the following century. The Conseil de guerre was composed of seven military officers sitting without professional judges, applying the Code pénal militaire of the time. The Conseil de révision provided a form of appeal, and the Conseil supérieur de guerre acted as the court of last resort for military offences.

The proceedings of the Conseil de guerre were notably summary compared to civilian courts. The accused had limited access to legal representation, the evidentiary rules were relaxed, and convictions could be based on the intime conviction (deeply held belief) of the military judges without the requirement for corroborating evidence. The system was criticised throughout the nineteenth century for its severity and lack of procedural safeguards.

The Conseil de guerre played a prominent role in politically sensitive cases. The trial of Captain Alfred Dreyfus in 1894 before the Conseil de guerre of Paris is the most notorious example, exposing the risks of military tribunals operating without adequate judicial independence or procedural rigour. The Dreyfus affair led to reforms, including the requirement for a professional judge to sit on military courts.

Wartime Jurisdiction and the Liberation

During the two World Wars, military courts exercised extended jurisdiction. The tribunaux militaires tried not only military personnel but also civilians accused of offences against the security of the state, espionage, and collaboration. The Code de justice militaire of 1928 codified the wartime regime, providing for tribunaux militaires aux armées that followed the armed forces into combat zones.

The post-Liberation period saw the establishment of the Haute Cour de Justice to try senior officials of the Vichy regime. The Haute Cour was a political jurisdiction composed of parliamentary deputies and senators, not a military court, but it applied military-style procedures and sanctions. Its most famous judgment was the conviction of Marshal Philippe Pétain in 1945.

The tribunaux militaires continued to operate in the post-war period, particularly in the context of the Algerian War (1954–1962). The tribunal militaire de Paris tried members of the Organisation Armée Secrète, including the attempted assassination of President de Gaulle. The use of military courts for civilian-related offences during the Algerian conflict generated increasing political opposition.

Abolition in Peacetime (1981)

The election of François Mitterrand in 1981 brought a radical reform of military justice. Law No. 81-737 of 28 July 1981 abolished military courts in peacetime, transferring jurisdiction over military personnel to the ordinary civilian courts. The reform reflected the view that military justice in peacetime was incompatible with the fundamental guarantees of a fair trial under Article 6 of the European Convention on Human Rights.

The abolition did not extend to wartime. The law preserved the possibility of re-establishing tribunaux militaires aux armées in time of war or during external operations. The Code de justice militaire continued to apply to military personnel, but the offences were now adjudicated by civilian courts applying ordinary criminal procedure.

The Conseil constitutionnel reviewed the reform in Décision n° 81-128 DC (1981) and confirmed its constitutionality, holding that the transfer of military justice to civilian courts did not violate any constitutional principle and that the preservation of wartime military courts was justified by the requirements of national defence.

The Code de Justice Militaire Reform

Following the 1981 abolition, the Code de justice militaire was fundamentally revised. Law No. 82-621 of 21 July 1982 created a new Code de justice militaire that reflected the reduced role of military courts. The code retained the substantive military offences—desertion, insubordination, abandonment of post, and conduct prejudicial to discipline—but aligned procedural rules with the Code de procédure pénale.

The reform introduced the pôle militaire of the Tribunal de Paris, a specialised section of the civilian court handling military offences. Military investigators from the gendarmerie nationale conduct investigations under the supervision of a civilian juge d’instruction specialising in military cases. Military personnel accused of offences retain all the procedural rights available to civilians, including the right to legal representation, bail, and appeal.

The Conseil supérieur de la justice militaire, which had acted as the highest military court, was replaced by the ordinary appellate courts, with the Cour de cassation exercising ultimate jurisdiction over military cases.

The Gendarmerie Status

The gendarmerie nationale occupies a unique position in French military justice. As a military force with police powers, the gendarmerie is both subject to military justice and responsible for investigating military offences. The Code de justice militaire applies to gendarmerie personnel, who are subject to military discipline while exercising civilian policing functions.

The status of the gendarmerie was clarified by Law No. 2009-971 of 3 August 2009, which placed the gendarmerie under the Ministry of the Interior for operational purposes while preserving its military status. Gendarmerie personnel accused of military offences are tried by the civilian courts under the same procedures applicable to other military personnel.

The Haute Cour de Justice (Constitutional)

The Haute Cour de Justice remains a constitutional institution under Articles 67 and 68 of the Constitution of 1958. It is composed of members of the Assemblée Nationale and the Sénat and is competent to try the President of the Republic for manquement à ses devoirs manifestement incompatible avec l’exercice de son mandat (breach of duties manifestly incompatible with the exercise of the presidential mandate).

The Haute Cour is not strictly a military court, but it retains the character of a political jurisdiction with historical roots in military justice. Its procedures are governed by the Ordonnance n° 58-1100 du 17 novembre 1958, which provides for investigation by a commission d’instruction and trial by the full Haute Cour. The Haute Cour has not been convened since the foundation of the Fifth Republic.

Contemporary Military Justice

French military justice in the twenty-first century operates as a specialised branch of civilian criminal justice. The pôle militaire de Paris handles approximately 500 cases annually, ranging from desertion and insubordination to military-specific offences such as loss of military equipment and breach of operational security. Sentencing is governed by the Code pénal and the Code de justice militaire, with military courts applying the same sentencing principles as civilian courts.

Military personnel retain the right to elect trial by a jury militaire for certain serious offences, composed of three military officers sitting with two professional judges. This hybrid composition preserves a military character in the most serious cases while ensuring professional judicial oversight.

Conclusion

The history of French military courts reflects the broader evolution of French constitutional democracy. From the Conseil de guerre of the Ancien Régime through the abolition of peacetime military courts in 1981, French military justice has progressively aligned with civilian standards while preserving specialised institutions for wartime and constitutional exceptional circumstances.
