Title Summary OSHA's Interpretation of a Regulation Upheld Briefed Case Appeals court held that OSHA's interpretation of a regulation requiring that workers to be protected from breathing silica dust was upheld when challenged by an employer who contended that another method of measuring silica dust should be used. The measurement method used by OSHA was reasonable and will be accorded deference. Since there was no expansion of substantive rules, no additional administrative procedure was required to justify the letters. Customs Service Ruling Letters Due Judicial Respect, Not Chevron Deference Briefed Case Supreme Court held that Customs Service ruling letters on tariff classifications of imported goods are not due the judicial deference of the Chevron doctrine that applies to regulations that go through the normal review process.
Letters are due judicial respect according to their care and completeness in logic.
The Supreme Court held that when Congress granted the EPA power to set air quality standards, in which it gave the agency broad powers and did not require cost considerations, it did not improperly delegate its legislative authority to an agency. The regulation the operator violated was vague. There was an Interpretive Letter that clarified the regulation, but the operator had no notice of the interpretation so could not be held liable for violating the regulation. No Jurisdiction to Review Statutory Privileges Suspended by Congress Briefed Case Appeals court held that federal courts did not have jurisdiction to review applications submitted by felons to the Bureau of Alcohol, Tobacco and Firearms requesting to have their right to possess firearms restored. Congress ordered the agency not to consider such applications, so none were possible and the courts could not intervene.
