On 17 August 1923, the French government proposed the convening of a diplomatic conference in November 1923 for the purpose of concluding a convention relating to liability in international carriage by air. The conference was formally deferred on two occasions due to reluctant behavior of the governments of various nations to act on such a short notice without the knowledge of the proposed convention. Finally, between 27 October and 6 November, the first conference met in Paris to study the draft convention. Since most of the participants were diplomats accredited to the French government and not professionals, it was agreed unanimously that a body of technical, legal experts be set up to study the draft convention prior to its submission to the diplomatic conference for approval. Accordingly, the International Technical Committee of Legal Experts on Air Questions ("Comité International Technique d’Experts Juridiques Aériens", CITEJA) was formed in 1925. In 1927–28 CITEJA studied and developed the proposed draft convention and developed it into the present package of unification of law and presented it at the Warsaw Conference, where it was approved between 4 and 12 October 1929. It unified an important sector of private air law.
