The Supreme Court handed down its final rulings of the October 2023 term, cementing this year as a historic one in the annals of constitutional and administrative law. Justice Amy Coney Barrett announced the first decision Monday in Corner Post Inc. v. Board of Governors of the Federal Reserve System, which as she joked from the bench, was not the opinion most gathered in the courtroom that day were eager to hear. The decision nevertheless adds to what has already been an historic one for the world of administrative law in light of Friday's decision overruling 40 years of "Chevron deference" to federal agencies during rulemaking challenges.

If that ruling, Loper Bright Enterprises v. Raimondo, makes it easier to prevail in such regulatory challenges, the court's Corner Post decision Monday makes it easier to bring such regulatory challenges in the first place. In particular, Justice Barrett wrote in a decision for the court's conservative majority that the six-year deadline to challenge a rule under the Administrative Procedure Act only begins when a plaintiff has been injured by the rule in question.
