Test students' ability to apply Chevron's two-step framework and the Major Questions Doctrine to agency rulemaking scenarios; require analysis of statutory text and context to determine ambiguity, assessment of whether an agency interpretation is reasonable and entitled to deference, and evaluation of whether a contested issue is sufficiently "major" (economic or political significance and clear congressional authorization) to displace deference under current Supreme Court doctrine. Scenarios will demand application of statutory interpretation, separation-of-powers principles, and reasoned justification of conclusions.
