## Facts

- Thunder Basin Coal Co. operated a surface coal mine in Wyoming with approximately 500 nonunion employees.
- The Federal Mine Safety and Health Amendments Act of 1977 (Mine Act) requires periodic, unannounced mine inspections by federal officials.
- The Mine Act grants a “walkaround” right: an operator representative and a miners’ authorized representative may accompany inspectors and participate in related conferences.
- Regulations define “miners’ representative” broadly to include any person or organization representing two or more miners for purposes of the Mine Act.
- Thunder Basin’s miners designated two United Mine Workers of America (UMWA) employees who were not mine employees as miners’ representatives.
- Thunder Basin refused to post the required notice identifying the miners’ representatives and objected that the designations impaired its claimed rights under the National Labor Relations Act (NLRA), including excluding nonemployee union organizers from its property.
- Before receiving an MSHA instruction letter directing compliance with the posting requirement, Thunder Basin filed a federal district court action seeking pre-enforcement injunctive relief against the agency’s interpretation and application of the Mine Act and regulations.

## Issues

1. Whether the Mine Act’s administrative review scheme impliedly precludes federal district court subject-matter jurisdiction over a mine operator’s pre-enforcement challenge to Mine Act regulations and agency interpretations.
2. Whether the availability of statutory, NLRA-based, and Fifth Amendment due process claims creates an exception permitting immediate district court review.

## Decision

- The Supreme Court affirmed the court of appeals and held that the Mine Act’s statutory review scheme precludes district court jurisdiction over Thunder Basin’s pre-enforcement suit.
- Congress’s intent to channel review was fairly discernible from the Mine Act’s structure, including an exclusive enforcement and review path through the Federal Mine Safety and Health Review Commission and then a court of appeals.
- The Mine Act provides meaningful review because the operator can raise statutory objections before the Commission and obtain judicial review in a court of appeals, which can consider constitutional claims.
- The Court rejected the argument that delayed review through enforcement proceedings, standing alone, violates Fifth Amendment due process.

## Legal Principles

- A comprehensive statutory review scheme may impliedly preclude initial district court jurisdiction when congressional intent to channel review is fairly discernible from the statute’s language, structure, purpose, and history.
- Preclusion applies even when the statute is silent on pre-enforcement suits, if the review provisions operate generally for disputes arising from enforcement of the statute and regulations.
- District court jurisdiction is not created merely because a regulated party frames objections as constitutional claims or as claims arising under another federal statute, where the statutory scheme allows meaningful review.
- “Meaningful review” exists where the scheme permits agency adjudication of statutory issues and subsequent review in an Article III court capable of resolving constitutional questions.
- Due process is satisfied where the scheme provides notice, an opportunity to be heard in administrative proceedings, and subsequent judicial review; the burdens of awaiting post-enforcement review ordinarily do not establish a due process violation.

## Conclusion

The Court held that the Mine Act channels mine operators’ challenges—including constitutional and NLRA-based objections—into the Commission-first review process with appellate review thereafter, thereby barring pre-enforcement district court suits against MSHA’s regulatory requirements and interpretations.
