Канада Жоғарғы Сотының «R v Lucas» ісі және сөз бостандығы шектеулері

R v Lucas is the leading Supreme Court of Canada decision on the criminal offence of defamatory libel. The Court held that the Criminal Code offence of defamatory libel infringed the constitutional protection of freedom of expression under Section 2(b) of the Canadian Charter of Rights and Freedoms, but the offence was a reasonable limit prescribed by law under Section 1 of the Charter.

A police investigation into a child sexual abuse case had resulted in charges against a number of people. Charges for four of them were stayed. These four went to see John Lucas, a prisoners' rights activist, for help with dealing with the effect the charges have had on their lives. Together they developed a theory that one of the police officers in the investigation had been complicit in the sexual abuse and had allowed the four to be charged. They picketed the provincial court house and the police station. Lucas held signs that said:
"Did [the police officer] help/or take part in the rape & sodomy of an 8 year old. The papers prove [the officer] allowed his witness to rape"; and "The papers prove [the officer] allowed the false arrest & detention of Mrs. Lucas, with a falsified information". Lucas was charged under section 300 of the Criminal Code. The provision required that the accused knew the statement to be false and knew it would expose the person to hatred, contempt, or ridicule. The issue before the Court was whether the Criminal Code provision violated the right to freedom of expression.

Justice Cory, for the majority of the Court, held that the provision violated the right to expression but was saved under section 1 of the Charter. He stated that protecting reputation from false attacks was a justifiable purpose of the law. Justice McLachlin wrote a separate concurring opinion but added that she was concerned that Cory's comments about the value of the statements would "lower the bar of justification from the outset of the s. 1 analysis".
