Article D115-1 of the French Code of Criminal Procedure
Sentence reductions apply to all custodial sentences, when the conviction has become final, including those managed under the semi-liberty, work release or electronically supervised home detention scheme. They do not, however, apply to imprisonment resulting from: 1° Withdrawal of a sentence reduction ordered pursuant to articles 721,721-2 and 723-35; 2° De la contrainte judiciaire.
