On 11 November 1765, La Chalotais, the "procureur" of the "parlement", was arrested, but whether at the instigation of d'Aiguillon is not certain. The conflict between d'Aiguillon and the Bretons lasted two years. In the place of the parlement, which had resigned, d'Aiguillon organised a tribunal of more or less competent judges, who were ridiculed by the pamphleteers and termed the "bailliage d'Aiguillon". In 1768, the duke was forced to suppress this tribunal, and returned to court, where he resumed his intrigue with the parti devot and finally obtained the dismissal of the minister Choiseul (24 December 1770).
