The U.S. Supreme Court appeared split over whether to allow Boulder County’s lawsuit against oil companies to proceed, with the justices appearing to harbor reservations about both sides’ sweeping arguments during Monday’s hearing.

The high court heard oral arguments in Suncor Energy v. County Commissioners of Boulder County on whether a lawsuit brought by the Colorado jurisdiction, which seeks to hold oil companies accountable for their alleged role in global climate change, can proceed.

The Boulder lawsuit claims oil companies should pay for knowingly deceiving people about climate risks associated with the use of fossil-fired energy.
