Seznec Affair

The Seznec Affair was a controversial French court case of 1923-1924.

Joseph Marie Guillaume Seznec, born in Plomodiern in Finistère in 1878 and the head of a sawmill at Morlaix, was found guilty of false promise and of the murder of the wood merchant Pierre Quéméneur, conseiller général of Finistère. Among other things, Quéméneur had strangely disappeared on the night of 25/26 May 1923 during a business trip from Brittany to Paris with Seznec, a trip linked (according to Seznec) to the sale of stocks of cars (left behind in France after the First World War by the American army) to the Soviet Union. Though many other possibilities were advanced as to the disappearance and despite the body never being recovered, it was decided only to pursue the murder hypothesis. Seznec became the prime suspect as the last person to have seen Quéméneur alive, and was arrested, charged and imprisoned.

Seznec was found guilty on 4 November 1924. During his eight-day trial, nearly 120 witnesses were heard. The avocat général had demanded the death penalty but since premeditation could not be proved, he was instead condemned to hard labour in perpetuity. He was taken to the prison of St-Laurent-du-Maroni in French Guiana in 1927, and transferred to the Îles du Salut penal colony in 1928.

Benefitting from a remission in his sentence in May 1947, he returned to Paris the following year. In 1953, in Paris, he was reversed into by a van that then drove off (the driver, later questioned, claimed not to have seen anything) and died of his injuries on 13 February 1954.

Throughout the trial and for the rest of his life, Seznec never stopped proclaiming his innocence. His descendents fought on to have the case reopened and clear his name (notably his grandson Denis Le Her-Seznec). Until today, all their attempts (14 in total) have failed.

The "commission de révision des condamnations pénales" nevertheless accepted, on 11 April 2005, a reopening of Guillaume Seznec's conviction for murder. This decision could open the way to an eventual annulling of his conviction in 1924. The criminal chamber of the Court of Cassation, France's appeals court, examined the case on 5 October 2006. At this point, Avocat général Jean-Yves Launay required the benefit of the doubt, to Seznec's benefit, raising more particularly the possibility of a police plot - the trainee inspector Pierre Bonny (twenty years later to be assistant to Henri Lafont, head of the Gestapo française) and his superior, commissaire Vidal were charged in the inquiry. At his side, the conseiller rapporteur Jean-Louis Castagnède maintained the opposite opinion, deducing on the one hand any such manipulation seemed improbable due to the few acts established by Bonny and on the other that the experts solicited by the cour de cassation had established that Guillaume Seznec really was the author of the false promise of sale of Quéméneur's property seized at Plourivo.
