Paul Cavalluzzo and Adrienne Telford appeared before the Supreme Court of Canada in the Groia v. Law Society of Upper Canada appeal.

Paul Cavalluzzo and Adrienne Telford appeared before the Supreme Court of Canada on November 6, 2017 in the Groia v. Law Society of Upper Canada appeal. They made submissions on behalf of the Ontario Crown Attorneys' Association on the appropriate standards of professional conduct required of lawyers appearing before the courts, including the lawyer's duty of civility.

This was the third time Paul and Adrienne have appeared before the Supreme Court of Canada in the past year. They represented the Specific Claims Tribunal in Williams Lake Indian Band v. Canada, a case relating to the historical grievances of the Secwepemc (Shuswap) Nation against the Crown with respect to their dispossession and loss of ancestral lands in the 1860s and 1870s.

They also represented Ontario teachers in British Columbia Teachers' Federation v. British Columbia. In that case, the Supreme Court of Canada found that the British Columbia government had substantially interfered with the collective bargaining rights of teachers in the province, contrary to section 2(d) of the Canadian Charter of Rights and Freedoms. The Court's decision restored collective agreement provisions which the provincial government had unconstitutionally suspended, including provisions limiting class sizes. The decision has resulted in the hiring of several thousand teachers in the province in order to return class sizes to their original limits under the collective agreements.
