The Supreme Court abandoned centuries of judicial tradition in five days during a 2016 climate case, birthing the secretive 'shadow docket' system that now fast-tracks major rulings on immigration and presidential power with minimal reasoning or deliberation. Chief Justice Roberts initiated the shadow docket to block Obama's clean power plan, motivated by perceived institutional slights rather than purely legal grounds, revealing partisan grievances driving major decisions. The shadow docket bypasses standard Supreme Court procedures—full briefing, oral arguments, and deliberation—enabling rulings issued in days with scant reasoning instead of the year-long merit docket process.
