Definition
Pro jet (also written projet): In international law, the draft or preliminary text of a proposed treaty or convention, circulated among negotiating parties for review, comment, and revision before formal adoption. A pro jet represents the working instrument of treaty negotiation — not a binding agreement, but the structured proposal from which a final instrument is shaped through diplomatic exchange.

Common Language
Modern common usage (Wiktionary): "Projet" in general French-derived English usage refers to a project or plan; no common legal or diplomatic meaning is recorded in standard English dictionaries.
Historical common usage (Webster's 1913): Not listed as an English entry; treated as a French borrowing meaning a project or scheme in the general sense.
Editorial note: The gap here is significant. In ordinary English, "project" or "plan" carries no formal procedural weight. In international law, a pro jet is a term of art denoting a specific stage in treaty formation — a drafted, structured proposal with diplomatic standing. Treating it as merely a working plan misses its function as the foundational text of negotiation.

Why It Matters in Research
Researchers working in historical international law materials — particularly 19th and early 20th century treaty records, diplomatic correspondence, and conventions — will encounter "projet" or "pro jet" as a recurring term in the procedural vocabulary of treaty-making. It signals that the document in question is not a concluded agreement and carries no binding force. Confusing a projet with an executed treaty is a consequential research error, particularly when tracing the history of a convention's final text against its earlier drafts.
The term appears most frequently in older anglophone legal sources that borrowed heavily from French diplomatic usage, reflecting the dominance of French as the language of 19th-century international diplomacy. In post-World War I sources and most modern treaty practice, "draft treaty," "draft convention," or "draft articles" largely displaced "projet" in English-language contexts, though the term persists in historical records and in French-language international instruments.
Corpus researchers should also note that "projet" appears in the records of early arbitration proceedings, multilateral conference documents, and the preparatory works (travaux préparatoires) of major conventions. When interpreting treaty obligations, understanding whether a provision appeared in the original projet or was added in later negotiation rounds can be material to construing intent.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed., Supplemental) provides the core entry: "Fr. In international law. The draft of a proposed treaty or convention." The definition is brief but accurate. It correctly flags the French origin and situates the term within its international law context.
What the historical dictionary entry does not address is the procedural relationship between the projet and subsequent stages of treaty formation — counter-projets, protocols of signature, final acts, and ratification. Nor does it distinguish between a projet submitted by one party and a joint draft developed multilaterally. These distinctions matter in research contexts where the authorship and evolution of treaty language are at issue.
No divergence among shelf sources is noted here, as the term is narrowly defined and the historical record is consistent. The primary limitation is brevity, not inaccuracy.

Encyclopedia Cross-Reference
Maritime Jurisdiction — Navigable Waters, Maritime Nexus (The Law Mind Military, Veterans & Admiralty Law Encyclopedia): Tangential. The encyclopedia entry addresses admiralty and maritime jurisdiction rather than treaty formation directly. Researchers focused specifically on treaty law or the law of international conventions should treat that entry as background context rather than a direct reference for pro jet.
