He has appeared in more than 20 cases at the Supreme Court of Canada, including as lead counsel to the successful appellants in Clyde River v. Petroleum Geo‑Services Inc., 2017 SCC 40, a landmark Indigenous rights decision.

Nader acts regularly for clients seeking to vindicate their constitutional rights in high-profile cases.  He has acted for the wrongfully convicted and asylum seekers.  He acts for Indigenous groups and environmental NGOs in environmental and constitutional cases.  He also acts for civil liberties groups, including the Criminal Lawyers’ Association, the British Columbia Civil Liberties Association, and the David Asper Centre for Constitutional Rights.
