Police can’t arrest to stop only potential disorder, Supreme Court rules
OTTAWA — Police do not have the power to arrest someone who is acting lawfully simply to prevent a possible outbreak of violence or disorder, the Supreme Court of Canada decided Friday.
According to the unanimous decision penned by Justice Suzanne Cote, such an arrest is not justifiable in cases where someone has not and is not about to commit an offence.
Cote said preserving the peace and other police duties are important, and “execution of these duties sometimes necessitates interference with the liberty of individuals… However, a free and democratic society cannot tolerate interference with the rights of law-abiding people as a measure of first resort. There is a line that cannot be crossed.”
Friday’s ruling from the country’s top court stems from a case when Ontario police arrested a man during a 2009 protest and counter-protest centred on the Grand River land dispute in Caledonia, Ont.
