A panel of judges reserved itsdecisionon Wednesday after hearing arguments from indigenous groups that the Canadian government had failed to properly consult them on expanding itsoilpipeline.
Thechallengeto the FederalCourtof Appeal is the latest obstacle to tripling capacity on the Alberta-to-British Columbia Trans Mountainpipeline, which the Canadianoilindustry says is badly needed.
"It feels like an acrimonious divorce. Obviously there’s a lot of tension here,” Chief Justice Marc Noël said, before saying the judges needed time to make adecisionafter a three-day hearing.
The operator ofCanada's state-ownedoilpipelinehad asked thecourtto dismiss the legalchallengeby four indigenous groups.

The indigenous groups "did not negotiate in good faith, or at all," Trans Mountain Corplawyer Maureen Killoran said. Effectively, the groups are attempting to hold a veto over the C$10 billion project despite the government's best attempts to address their concerns, she said.
"This was not a drive-by consultation," Killoran said.
Coldwater Indian Band, one of the four groups, refused to allow drilling for a hydro-geological study to determine risks to its aquifer, she said. The band said earlier this week that protecting its drinking water was its main concern.
The indigenous groups alleged that the Canadian government shared key reports on the project's impact late, or even after the consultation period and that it revised documents. Their concerns include possibleoilspills and threats to endangered southern resident killer whales.
Ottawa bought thepipelinelast year to ensure expansion proceeded, offering a lifeline to Alberta's strugglingoilpatch. Congestedpipelines have forced the Alberta provincial government to curtail production.
Acourtruled in August 2018 that Ottawa had failed to properly consult indigenous people, prompting the government to redo the consultation process before reapproving the expansion in June. But in September, theCourtof Appeal agreed to hear fresh concerns that the government fell short again.
In a written submission, Alberta's government said consultation for Trans Mountain was more extensive than that of any other Canadian infrastructure project, and federal approval should remain in place.
"Regulatory instability and legal uncertainty negatively affect reliable planning and put a chill on investor confidence," lawyers for Alberta's attorney general wrote.
"Consultation is unworkable when, as in this case, it appears the only compromise acceptable to an indigenous group is the abandonment of the project," they added.
