The applicants, an anti-abortion organization and its youth coordinator, sought to display graphic images of fetuses during a protest on Parliament Hill.
Officers from the Parliamentary Protective Service (PPS) prohibited the display, citing rules against obscene or hateful messages.
The applicants brought an application arguing this violated their freedom of expression under s. 2(b) of the Charter.
The Superior Court of Justice found that the PPS's operational decision breached the applicants' Charter rights and was not justified under s. 1, as the specific prohibition on graphic images was not yet published at the time.
The court granted a declaration that the rights were infringed but declined to strike down the rules governing Parliament Hill, as the rule-making committee was not a party to the proceeding.
