Assess and apply administrative law doctrines—notice-and-comment procedures, Chevron vs. Skidmore deference, and arbitrary-and-capricious review—together with separation-of-powers principles to evaluate factual rulemaking scenarios in complex industries and to draft legally resilient regulatory text and supporting legal rationale. Tasks include analyzing procedural compliance, identifying vulnerabilities to judicial review, selecting persuasive deference strategies, and proposing revisions to strengthen statutory and constitutional defensibility in technical sectors (e.g., energy, finance, telecom, healthcare).
