The criminal trial continued for most of the summer and Carrouges, Le Gris and Marguerite were all called on to give evidence. Marguerite was by this time visibly pregnant, although medieval medical knowledge claimed that children could not be conceived as a result of rape and her condition therefore was determined to have no bearing on the case. Adam Louvel and at least one of Marguerite's maidservants also gave evidence and, as was the custom of the day for people of low birth, they were tortured to test the veracity of their testimony. During this process neither produced evidence incriminating Le Gris, although Louvel was subsequently challenged to a duel himself by Marguerite's cousin, Thomin du Bois. In his evidence, Carrouges statement primarily repeated and supported his wife's testimony, while Le Gris accused Carrouges of inventing the charges and beating his wife into making the accusations against the squire. In his statement, Le Gris painted a picture of a man driven wild with anger and jealousy who sought to restore his family fortune by concocting false accusations against his most significant rival. Le Gris also offered alibis for his whereabouts during the entire week the crime was supposed to have been committed and attempted to explain that it was not possible for him to have ridden the twenty-five miles which supposedly separated him from Marguerite on the morning in question. A rebuttal from Carrouges emphasised the shame the trial had brought to his family as a reason against its invention and offered a counter demonstration of horsemanship indicating that the suggested fifty mile round trip was not impossible even if Le Gris's alibi was true. Le Gris' alibi was compromised some days later when the man providing it, a squire named Jean Beloteau, was arrested for committing rape in Paris even as the trial progressed. On 15 September, with the King in Flanders preparing for an invasion of England, the parlement handed down its verdict: As they had been unable to determine the guilt in the case, the two men would fight a duel to the death on 27 November 1386.
