Tréveneuc law

Tréveneuc law is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tréveneuc law rather than just read about it. In short: The Tréveneuc Law (French: loi Tréveneuc) was a law passed in the early days of the French Third Republic which established a legal framework by which the country could invoke a state of emergency (régime d'exception) in order to oppose a power grab by a rogue chief executive who illegitimately dissolved the National Assembly. The law was passed on 15 February 1872 by the National Assembly of France during the provi…

Key takeaways

  • Tréveneuc law belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tréveneuc law to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tréveneuc law from memory before moving on to harder problems.

Reference excerpt

The Tréveneuc Law (French: loi Tréveneuc) was a law passed in the early days of the French Third Republic which established a legal framework by which the country could invoke a state of emergency (régime d'exception) in order to oppose a power grab by a rogue chief executive who illegitimately dissolved the National Assembly. The law was passed on 15 February 1872 by the National Assembly of France during the provisional period of the Third Republic. There were several occasions where serious discussion or attempts to invoke the Tréveneuc law arose, in particular several times during World War II, either by the Vichy regime, or by those opposing it. In 150 years, the law has never been repealed and is still in force, and since 2000 has been mentioned in political discourse in France under a number of different circumstances.

Name and date

The Tréveneuc law is entitled, "the law of 15 February 1872 relating to the possible role of departmental councils in exceptional circumstances". It is usually dated 15 February 1872 in France, the day of its adoption. But it is also known as the law of 22 February 1872 in France, the day of its promulgation. It is also known as the Tréveneuc Constitution because it is one of the constitutional laws adopted by the National Assembly elected on 8 February 1871 in France.

Development On 25 July 1871, Henri, Viscount of Tréveneuc and representative of Côtes-du-Nord in the National Assembly, presented a bill, co-authored by Charles de Janzé and Émile Depasse. On August 11, 1781, its examination in committee began. On February 5, 1872, the discussion began. On February 15, 1872, the National Assembly adopted it by 480 votes to 75. On February 22, 1872, Adolphe Thiers, President of the Republic, promulgated it. The following day, it was published in the Official Journal; then, on March 30, 1872, in the Bulletin des lois.

Description Under the exceptional circumstances envisioned by the law, the power normally held by the national legislature is partially devolved to the departmental councils, who are to meet "immediately" to maintain public order locally, and calls for the establishment of an "Assembly of Delegates" (assemblée des délégués) consisting of two delegates elected from each departmental council. The delegates are to rejoin the legal members of the government wherever they happen to be, and to jointly take all necessary measures to maintain order and to ensure the independence and viability of the National Assembly, including calling for national elections. If after a month the National Assembly is still not back, then the emergency framework invests the Assembly of Delegates with further powers, including both legislative and administrative power, and instills its executive decisions with a legal force which are obligatory on all agents of public order, under penalty of "forfeiture". It is sometimes characterized as part of the constitution, or called the "Tréveneuc constitution". The Tréveneuc law consists of six articles. It provides for its use in the event that the Parliament is illegally dissolved or prevented from sitting, for any reason whatsoever, in the places assigned to them in Paris or in any other city where the Government has transferred the seat of public powers. The second article establishes the measures to be implemented if the National Parliament is unable to meet: it is thus up to the general councils to meet and provide "urgently for the maintenance of public tranquility and legal order". Articles 3 to 6 relate to the assembly of delegates from the departmental councils. Each county council must elect two delegates. The general councils must each send two delegates to the Government (article 3) - which supposes that the latter has been able to escape the cause which prevents the Parliament from meeting, in order to constitute a provisional deliberative assembly with the possible national deputies who could have followed the Government. The law assigns itself a double objective: to provide for the measures immediately necessary for the administration of the country, and for the restoration of the constitutional mandate, either of that previously in progress, or of a new one, resulting from general elections, which must be convened after one month of exercise of the "Assembly of Delegates". The text recognises the events of the war of 1870, and therefore a desire to guard against their repetition, or against a civil war which would prevent Parliament from meeting.

Attempted uses

Giraud in 1943 The law was used to justify the creation of Free France and the Provisional Government of the French Republic.

Guadeloupe On 17 June in Guadeloupe, one of France's colonial possessions in the Caribbean, Paul Valentino announced that he was going to ask the Departmental Council of Guadeloupe to apply the Tréveneuc law, and on 1 July, he repeated his request at an extraordinary session. President Nicolas Sarkozy paid homage to Valentino and others in a 2009 speech, saying of Valentino: "Steeped in the republican spirit, Valentino believed in the law. That's why he was the first to invoke an old law of the Third Republic, the Tréveneuc Law, to declare the new regime, born under the German boot, illegal."

Vichy René Cassin argued that the armistice of 22 June was null and void by virtue of the Tréveneuc law. In order to prevent its implementation, the Vichy Regime passed two laws: the first, of 18 August, prohibited the general councils from meeting spontaneously; the second, of 12 October, suspended the sessions of the general councils and transferred their powers to the prefects. The Tréveneuc law appeared at the top of the page of the constitutional declaration of 16 November, in which Charles de Gaulle supplemented the Brazzaville Manifesto of 27 October.

Algeria According to Michèle Cointet-Labrousse, the General Councils of Algeria considered implementing the Tréveneuc Law in 1943.

Worked examples

Example 1 — a first encounter with Tréveneuc law

Start with the simplest possible case. Write down what Tréveneuc law claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tréveneuc law before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tréveneuc law ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tréveneuc law

In research
Tréveneuc law appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tréveneuc law in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tréveneuc law is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1872 in France, 1872 in law, Constitutions of France, so understanding it makes those chapters shorter.
In everyday life
Look for Tréveneuc law outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
