Kinder Morgan seeks to expand Burnaby Mountain injunction

Pipeline company Kinder Morgan will be back in B.C. Supreme Court today asking for an expansion of an injunction keeping protesters out of its two drilling sites on Burnaby Mountain.

The company is expected to ask the judge to expand the area covered by the injunction and push back the expiration date on the court order from Dec. 1 to Dec. 12 so it can make up for lost time.

The move comes after the B.C. Civil Liberties Association said yesterday that dozens of arrests made under the injunction may not be legal because the police line did not match the area covered by the injunction.

Josh Paterson, Executive Director of the Civil Liberties Association, said in written release there is confusion over the exact GPS coordinates of the zone and it's causing problems for both demonstrators and the RCMP.

Meanwhile Grand Chief Phillip Stewart of the Union of B.C. Indian Chiefs says he plans join the ranks of more than 100 protesters arrested for violating the injunction on the mountain sometime today.

Kinder Morgan obtained the injunction two weeks ago to remove protesters camped out at the site. The company has since begun test drilling at the site to determine if it can bore a tunnel under the mountain as a new route for its proposed expansion of its existing Trans Mountain pipeline.
