NLRB v. Hearst Publications - Judicial Deference to Agencies & The Substantial Evidence Test

Video lecture for my Administrative Law course & my Statutory Interpretation & Regulation course (Leg-Reg) about the landmark case National Labor Relations Board v. Hearst Publications, 322 U.S. 111 (1944), which addresses judicial deference to agency findings of FACT (or mixed questions of fact & law) and the "substantial evidence" test that was later incorporated into the Administrative Procedure Act for formal adjudication or formal rulemaking proceedings by regulatory agencies, commissions, & boards.
