Former judge Jean-Guy Boilard has surfaced a previously undisclosed document that is now central to a $64 million civil lawsuit filed by Claude Paquin. Paquin, who was convicted of a 1983 double murder, was acquitted 41 years later after a lengthy legal battle. The document, a 1987 letter from informant Réal Simard, suggests that prosecutors were aware of perjury by the key witness in Paquin’s original trial years before the conviction was overturned.
Evidence of Perjury in the 1983 Double Murder Case
Claude Paquin is seeking $64 million in damages from the Montreal police and the Quebec Attorney General. His claim covers 18 years spent in prison and 23 years on conditional release following his 1983 conviction for the murders of Ronald Bourgoin and Sylvie Revah. The conviction relied on the testimony of Bernard Provençal, a known informant who claimed Paquin ordered the killings.

According to the document held by Jean-Guy Boilard, the case against Paquin was built on testimony that was highly suspect. The letter from Réal Simard, a mafia hitman and informant, reveals that Michel Telmosse—one of the three men originally convicted—admitted to Simard that he was present at the scene of the murders, but that co-defendant Jean-Pierre Gauthier was not. This information contradicts the testimony provided by Provençal, who had implicated all three men.
Did You Know?
The 1987 letter from Réal Simard was originally sent to Jean-Guy Boilard because Simard mistakenly believed the judge had presided over the trial. Boilard, who presided over several criminal trials from 1976 to 2012, advised Simard to contact the chief prosecutor, Yves Lagacé, and his deputy, Claude Parent.
The Role of Informants and Crown Disclosure
The existence of the letter suggests that prosecutors had early warnings about the reliability of Bernard Provençal. Following the period when Simard communicated his findings, the Crown dropped charges against Jean-Pierre Gauthier, citing “privileged information.” However, this information was never disclosed to Claude Paquin, who remained incarcerated.

Jean-Guy Boilard, who kept the correspondence for nearly 40 years, has long criticized the reliance on informant testimony. He notes that the Crown often acted as a “spokesperson for the police” during that era, creating a systemic imbalance. He points out that the government was historically slow to acknowledge errors in cases involving these witnesses, and that the police held significant, unchecked power in the administration of justice.
The case highlights the evolution of law, which now requires formal contracts outlining benefits provided to informants to prevent the lack of transparency observed in the 1980s.
Potential Legal Implications
The discovery of the letter provides a specific, documented instance of information known to the state regarding the unreliability of its star witness.
Frequently Asked Questions
Why is the letter from Réal Simard important to the civil case?
The letter demonstrates that as early as 1987, authorities were aware of information suggesting that the primary witness, Bernard Provençal, had committed perjury, yet this information was not disclosed to Claude Paquin.
What was the relationship between Bernard Provençal and the investigation?
Provençal was an informant who provided testimony against Paquin, Gauthier, and Telmosse in exchange for money and various privileges. It was later revealed that Provençal himself was involved in the murders.
What changes were made to the justice system following these events?
In the wake of scandals involving informant testimony in the 1980s, the justice system introduced reforms requiring the state to sign formal contracts with “repentant” witnesses, explicitly detailing all financial and judicial benefits provided in exchange for their cooperation.
How should the justice system balance the use of informants with the necessity of ensuring a fair trial for all defendants?
