HudBay Minerals Inc. (TSX:HBM) is suing the Mathias Colomb Cree Nation over rallies held this year that it claims blocked the entrance to its Lalor Lake site.
Chief Justice Glenn Joyal of Court of Queen's Bench has ruled protesters can't block roads into the site, where a gold, zinc and copper mine is being developed.
Joyal says he's confident RCMP will enforce the injunction with arrests, if necessary.
Mathias Colomb Chief Arlen Dumas says the injunction violates freedom of expression laws.
He and a group of supporters stormed out of court Wednesday during the hearing.
"The lawyer for Mathias Colomb Cree Nation was not permitted to finish any of his arguments, was constantly interupted and not permitted reasonable time to review surprise affadavits filed by Hudbay lawyers," Dumas said in a release.
"The judge made most of Hudbay's arguments for them and allowed their lawyer uninterupted presentation time."
There have been two blockades over the winter, which the company claims hurt business and put the safety of workers at risk.
Dumas has said his members did not prevent access to the site, but simply held peaceful demonstrations.
The First Nation contends that HudBay and the Manitoba government, which licenses mines, should have obtained consent from area aboriginals before going ahead with development. (CJOB)
