The ancestors of the Blueberry River First Nations (BRFN) adhered to Treaty 8 in 1900. The treaty provides that they have continuing hunting, trapping and fishing rights throughout the treaty territory, except on lands taken up for settlement, mining, lumbering, trading, or other purposes. The province of British Columbia has been taking up lands for industrial purposes for many years, significantly diminishing the area available for the BRFN to exercise their treaty rights. The BC Supreme Court held that the province had infringed the treaty rights by taking up lands to such an extent that there were no longer sufficient lands left for the BRFN to meaningfully exercise their treaty rights. The province had not justified the infringement, nor had it responded to the BRFN's concerns, as required by the honour of the Crown and its fiduciary obligations. The court declared that the "Province may not continue to authorize activities that breach the promises included in the Treaty, including the Province's honourable and fiduciary obligations associated with the Treaty, or that unjustifiably infringe Blueberry's exercise of its treaty rights." The court also declared that the parties must act diligently to establish enforcement mechanisms so the cumulative impact of industrial development on the treaty rights can be assessed and managed and to ensure the constitutional rights of the BRFN are respected. This decision was not appealed.
