On 6 January, the Governor General of Canada granted a request for a two-month prorogation of parliament. A legal challenge was soon launched to have it declared unlawful. Steven Chaplin argues that the prorogation is perfectly proper, that it is highly unlikely that a Canadian court will rule it to be unlawful, and that comparisons with the Boris Johnson prorogation request in 2019 and the subsequent ‘Miller 2’ case do not hold up.
