Administrative Law course lecture video about the case National Federation of Independent Business v. OSHA, 142 S.Ct. 661 (2022) (the "vaccine mandate" case) and the Supreme Court's evolving Major Questions Doctrine. This video offers an in-depth analysis of the NFIB v. OSHA Supreme Court case from 2022, focusing on the vaccine mandate for employers. It explores how the Court's anonymous per curiam opinion invalidated OSHA's emergency temporary standard, concluding that the agency exceeded its statutory authority by addressing a broad public health issue rather than a specific workplace hazard. The discussion highlights the evolving major questions doctrine, particularly Justice Gorsuch's "no elephants in mouseholes" interpretation, and critiques the majority's reasoning, including its unusual reliance on a failed Senate resolution. Conversely, the text presents the dissenting justices' arguments, emphasizing the reasonableness of OSHA's rule in addressing a "grave danger" like COVID-19 in workplaces and asserting the agency's historical precedent for similar regulations.
