The Alberta Teachers’ Association (ATA) has rescheduled its constitutional challenge against the Back to School Act to July 2027, a delay of nearly ten months from the original September hearing. The ATA requested this postponement to await decisions from the Supreme Court of Canada on two related cases that could set important legal precedents regarding the use of the notwithstanding clause by provincial governments. The Back to School Act, passed in October 2022 following a three-week strike, mandated over 51,000 teachers to return to work and imposed a four-year collective agreement, invoking the notwithstanding clause to avoid legal challenges. The ATA argues that the act infringes on teachers' constitutional rights and was improperly applied retroactively. Last month, the ATA's attempt to obtain a temporary injunction against the act was denied by Court of King’s Bench Justice Douglas Mah, who ruled that the ATA did not demonstrate irreparable harm or that the public interest favored granting the injunction. The Alberta government has refrained from commenting further, stating that court scheduling is a matter for the judiciary.
