Aboriginal Law
Sacha is a member of the English River First Nation, a Dene community located in Northern Saskatchewan. His long-standing interest in Indigenous issues has resulted in an Aboriginal law practice. Sacha has experience working for resource developers, such as mining companies, forestry companies, and hydro-electric utilities, in engaging with First Nations and Metis communities, particularly when it comes to future resource developments or the impacts of past developments.
In addition, Sacha has developed a practice respecting First Nation elections and governance issues. He has acted for Indigenous Governments/Tribunals in enforcing orders to remove people from Chief and Council and has acted for First Nation people in challenging elections.
Public Law/Administrative Law
Sacha’s work in Aboriginal law ties into his practice in Public Law/Administrative law. Aboriginal law frequently engages principles of administrative law, such as duties of fairness. In addition to acting for Indigenous Tribunals, Sacha has acted for and provided advice to other administrative tribunals, such as Workers’ Compensation tribunals and Residential Tenancies tribunals.
In the area of Public law, Sacha has experience with human rights under human rights legislation and the Charter of Rights and Freedoms. For example, Sacha acted for Amnesty International in the case of Canada v. Khadr respecting “life, liberty and security of the person” rights under the Charter. Sacha has also acted for clients respecting addressing human rights issues, such as equality rights.
