The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Scheduled, per the Court's docket: "SET FOR ARGUMENT on Monday, October 5, 2026"; the October argument calendar lists 25-170 as case (1) that Monday and states "Court convenes at 10 a.m."
The Court's own calendar lists "Monday, October 5 ... (1) SUNCOR ENERGY (U.S.A.) INC. V. COMMISSIONERS OF BOULDER COUNTY[7]" and "Court convenes at 10 a.m." (amended September 14, 2026).
Case file gives argument date Monday, October 5, 2026, the question presented, the added Article III jurisdiction question, and cert granted February 23, 2026.[1]
Boulder Valley Frequency's episode is squarely about this case, with the host saying "the Suncor Boulder County[7] case, which the Supreme Court[1][2] is set to hear on October 5th" and noting it's the first case of the new term, matching the pin date. Capped because this is a small local/hobbyist-scale podcast rather than an established news outlet, even though the guest is an expert commentator.
Confirms the October 5 argument as the term's opening case, the Justice Department amicus brief backing the oil companies, and that a ruling could end "more than two dozen climate liability lawsuits".[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
