attendu que

1. Legal Function and Structure
In traditional French jurisprudence, a judgment was often written as one long sentence. The ruling begins with the Visa, a citation of the law being applied, introduced by Vu (e.g., Vu l'article 1382...). This is followed by the Motifs (reasons), where paragraphs generally begin with Attendu que (capitalized) and end with a semicolon (;). However, if a single line of reasoning spans multiple paragraphs, the subsequent paragraphs begin simply with Que... to avoid repetition. The final decision follows a phrase like 'Par ces motifs.'

2. Prepositional Usage
Beyond the conjunctional form, attendu can function as a preposition followed directly by a noun phrase, meaning 'in view of' or 'given.' For example: Attendu l'urgence de la situation... (Given the urgency of the situation...). In this usage, it remains strictly invariable and does not agree in gender or number with the noun. For instance, you must write Attendu les circonstances... (Given the circumstances...) and never Attendues les circonstances....

3. Mood and Grammar
Even though the verb attendre usually triggers the subjunctive when expressing a wait (e.g., J'attends qu'il vienne), the locution attendu que always takes the indicative. This is because it states a fact or a legal reality that is being taken into consideration.

4. Register and Modern Usage
This expression is restricted to the style soutenu (formal register). You will find it in court rulings, administrative resolutions, and formal contracts. Note: The French high courts have recently modernized their drafting to make law more accessible. The Conseil constitutionnel pioneered this change in 2016, followed by the Conseil d'État in 2018. The Cour de cassation, after initiating its reflection in 2014, adopted a 'direct style' in 2019. Instead of repeating the phrase every paragraph, the Conseil d'État now uses a single overarching phrase ('Considérant ce qui suit :'), while the Cour de cassation uses plain headings like 'Examen des moyens'. Though replaced in modern drafting, attendu que remains essential for reading historical case law.

5. Attendu que vs. Considérant que
While both mean 'whereas,' they traditionally had different primary usages, though the distinction was not absolute:

• Attendu que: Primarily used by the highest judicial court (the Cour de cassation).
• Considérant que: Used by administrative courts (like the Conseil d'État), the Conseil constitutionnel, and historically by lower civil courts.

6. The Structural Pivot: Mais attendu que
A highly famous and critical structural pivot in French case law is Mais attendu que. It is used by the Cour de cassation to introduce the Supreme Court's own counter-reasoning, effectively rejecting the arguments presented by the appellant.

7. Key Concepts and Synonyms
Because of the repetitive use of this conjunction in legal drafting, un attendu became a standalone noun meaning a 'paragraph' or 'recital' in a judgment. In legal theory, an attendu de principe is a specific paragraph where the court defines a general rule of law. While attendu que is highly specialized, you can use more common causal conjunctions like étant donné que, vu que, or puisque in formal but non-legal writing to express similar logic.
