Two B.C. First Nations filed for a judicial review of TransCanada Corp.’s Coastal GasLink pipeline project in a Vancouver court house this morning.

The Nadleh Whut’en First Nation and the Nak’azdli First Nation argue the Crown’s ‘duty-to-consult’ was not met when the province’s Environmental Assessment Office approved the 650-kilometer natural gas pipeline on October 24.

“We took every step possible to make our concerns known to B.C. and to work with the province to have our concerns addressed,” said Chief Martin Louie of the Nadleh Whut’en First Nation. “Unfortunately, B.C. rushed the project through the environmental assessment process and left us with no other option.”

The First Nations examined the 32 conditions inside the assessment certificate and found they did not adequately reflect the recommendations they made in hundreds of pages of submissions to the office, said their lawyer Merle Alexander.

“They’re challenging primarily on the basis that there’s been a failure to fulfill the duty-to-consult and accommodate the First Nations,” said Alexander, a partner at Gowlings in Vancouver.

This is the first legal challenge brought by a First Nation against the LNG industry, said Alexander. There has been an active threat of legal opposition to the Petronas LNG project but it’s currently in a holding pattern, he added.

First Nations in B.C. have been critical of federal and provincial government policies that put the onus of duty-to-consult onto proponents in large-scale industrial projects. This approach leads to government-led processes like regulatory approvals and reviews that First Nations say don’t meet the constitutional requirements of duty-to-consult.

The First Nations in the GasLink case are particularity concerned about the Environmental Assessment Office’s dual role as the regulator carrying out the duty-to-consult and the body that decides whether that duty has been met, said Alexander.

The Supreme Court of Canada’s decision to recognize the aboriginal title of the Tsilhqot’in First Nation in June likely will play a role in the Nadleh Whut’en First Nation and the Nak’azdli First Nation’s legal arguments, he said.

While First Nation concerns about duty-to-consult policies have been long-standing in the province, the B.C. government’s rush to promote a liquified natural gas (LNG) export industry have put renewed attention on the duty-to-consult.

The province’s natural gas is mainly located in the northeast, near the Alberta border, and so a half-dozen pipeline projects have been proposed by industry to carry gas to ports on the Pacific coast, where several liquefaction plants and export terminals have also been proposed.

Several of these pipelines cross the Nak’azdli First Nation’s territory and two would cross the Nadleh Whut’en First Nation’s land, but the Coastal GasLink is the first to see its approval certificate challenged by a First Nation, said Alexander.

Aside from the duty-to-consult, the simultaneous pipeline proposals have drained the First Nations’ ability to process them and have raised questions about how to assess their impact, said Alexander.

“In the very unlikely circumstance that all the project occurred, their territory would just get sliced into multiple pieces,” he said.

The Coastal GasLink project would carry gas from the Montney formation near Dawson Creek, B.C., to the proposed LNG Canada export facility near Kitimat. LNG Canada is owned by a consortium that includes Shell, Korea’s KOGAS and PetroChina.

The federal government is intensely involved in breaking the impasse between First Nations, the province and the LNG sector. Vancouver lawyer Doug Eyford was commissioned by Ottawa to report on the situation in 2013.

The resulting Eyford report called for a new federal push to fund consultation processes and improve its presence in northern B.C. Natural Resources Canada and Aboriginal Affairs and Northern Development Canada are still actively unveiling new policies to help projects get ahead.

Both the Nadleh Whut’en First Nation and the Nak’azdli First Nation are involved in negotiations over economic benefit packages with TransCanada but these are not considered part of the duty-to-consult process, said Alexander.

“We are not against development”, said Chief Fred Sam of the Nak’azdli First Nation in a news release. “Industry is just as frustrated as we are with how B.C. is managing its relationships with First Nations, especially after the Supreme Court’s decision in the Tsilhqot’in case this year.”

Earlier this month, the Wet’suwet’en First Nation signed a $2.8 million economic benefits agreement with the Coastal GasLink project.

Other First Nations in B.C. have begun litigation involving Enbridge Inc.’s Northern Gateway oil pipeline and B.C. Hydro’s Site C hydroelectric dam over the past year.
