American Mining Congress v. Mine Safety & Health Administration

The Court was called upon to determine whether the PPL on the issue of x-rays was an interpretive rule, in which case it would be valid, or a legislative rule, in which case it would be invalid (for not being enacted in accordance with the Administrative Procedure Act). The Court used a four-part test to determine whether the rule was legislative (an affirmative answer to any one means the rule is legislative):

1. Whether in the absence of the rule there would not be an adequate legislative basis for enforcement action or other agency action to confer benefits or ensure the performance of duties;
2. Whether the agency has published the rule in the code of federal regulations;
3. Whether the agency has explicitly invoked its general legislative authority;
4. Whether the rule effectively amends a prior legislative rule. Subsequent caselaw has minimized the importance of the second factor.
