A second British Columbia member of Parliament has been ordered to fork over some money to the state after violating a court injunction.

Green Party of Canada Leader Elizabeth May has been sentenced to a $1,500 fine for standing in front of Kinder Morgan's gates in Burnaby on March 23.

She and NDP MP Kennedy Stewart were both arrested that day, and Stewart was fined $500 earlier this month.

May told the court that she promised the Tsleil-Waututh, Squamish, and Musqueam First Nations that she would stand with them to oppose Kinder Morgan's $7.4-billion pipeline project.

It will triple shipments of diluted bitumen through its Trans Mountain system to 890,000 barrels per day. That, in turn, is expected to lead to a nearly seven-fold increase in oil-tanker traffic in the waters off Vancouver.

"I made the choice to undertake an act of civil disobedience," May said in court. "I knew the consequences and in pleading guilty today, I accept the consequences of my actions."

Justice Kenneth Affleck issued the injunction earlier this year, ordering protesters to stay at least five metres away from Kinder Morgan's facilities in Burnaby.

He is also the B.C. Supreme Court judge who sentenced both Stewart and May.

Prior to becoming a judge in 2011, Affleck practised law with Affleck Hira Burgoyne LLP and Macaulay McColl.

Among his clients were Rothmans, Benson & Hedges Inc., for whom he acted in a landmark B.C. government lawsuit against the tobacco industry.
