...Canada’s top court said... that Nevsun filed an application on Jan. 19, seeking permission to appeal a British Columbia court ruling in November, which confirmed the case could proceed in the western Canadian province.

The Supreme Court can grant or deny such applications and there is no fixed time for a decision.

Nevsun confirmed its appeal, but said it would not otherwise comment.

...Nevsun said that it was inappropriate [that] British Columbia judge the legality of a sovereign state’s conduct...

...Nevsun previously argued the case should be dismissed and any lawsuit should be heard in Eritrea, not Canada.
