Provisional Government of the French Republic
On the downfall of the Vichy regime, Abrial was arrested and charged with collaboration, for which he lost his pension. After the Provisional Government of the French Republic re-established the "Haute Cour de justice", that court condemned him for his Nazi collaboration and sentenced him to ten years of forced labor. In December 1947, however, he gained provisional release, and in 1954 he was granted amnesty.
