A memorandum within the file translates it as "Judge Donat Lalande seems to act as a persecutor in the matter of Ernest Davignon charged with blasphemous libel. Ask that investigation be made." A government official replied to Godin that the presiding magistrate was appointed by the Quebec provincial government and thus his conduct was outside of Federal jurisdiction. The file contains no further mention of the matter.
I thought I might come across the Davignon case while doing my survey of blasphemy cases reported in The Globe and Mail and The Toronto Star during that time period, but nothing came up. It may be worth a more focussed search sometime in the future to see just who Ernest Davignon was and why he was alleged to have blasphemed.
