Facts
- Pennsylvania enacted the Bituminous Mine Subsidence and Land Conservation Act to prevent or minimize land subsidence from underground coal mining and to address resulting harms to buildings, land, and water resources.
- Section 4 barred mining that would cause subsidence damage to specified existing surface interests, including certain public buildings, dwellings, and cemeteries.
- Implementing regulations required mine operators to leave at least 50% of the coal beneath protected structures in place to provide surface support (the “50% rule”) and extended protection to certain watercourses.
- Section 6 authorized the state environmental agency to revoke a mining permit if mining caused damage to a protected structure or area and, within six months, the operator did not repair the damage, satisfy claims, or post security for repair costs.
- Coal operators and a trade association asserted that Pennsylvania recognizes a distinct “support estate” and that the statute effectively destroyed that estate and nullified contractual waivers of subsidence liability obtained from surface owners.
- Petitioners brought a facial challenge seeking to enjoin enforcement, alleging an uncompensated regulatory taking and an unconstitutional impairment of contracts.
- The district court entered summary judgment for the state officials, and the court of appeals affirmed.
Issues
- Whether the Act’s mining restrictions and permit-revocation mechanism, including the 50% rule, effect a facial taking of private property without just compensation under the Fifth and Fourteenth Amendments.
- Whether the Act unconstitutionally impairs preexisting private contracts that waived subsidence-damage liability, in violation of the Contracts Clause.
Decision
- The Supreme Court affirmed.
- The Court held petitioners failed to show that the Act and regulations effected a facial taking.
- The Court held any impairment of subsidence-waiver contracts was justified by a significant and legitimate public purpose and therefore did not violate the Contracts Clause.
- The Court distinguished earlier precedent invalidating a different Pennsylvania mining restriction, emphasizing the stronger public-protection rationale and the absence of a showing of severe economic deprivation here.
- The dissent would have found the restrictions and contract interference sufficiently burdensome to constitute an unconstitutional taking.
Legal Principles
- A facial regulatory-takings claim requires showing that the mere enactment of the regulation denies economically viable use; generalized assertions of impairment are insufficient without concrete proof of severe economic impact.
- Takings analysis evaluates the economic impact with reference to the “parcel as a whole,” and generally rejects defining the relevant property interest as a segmented component (such as a separate support estate) to manufacture a taking.
- Regulations aimed at preventing serious harms to public health, safety, and the environment are more likely to be upheld as valid exercises of the police power when the state does not appropriate the property and owners retain substantial productive use.
- Under modern Contracts Clause doctrine, a state may impair private contractual arrangements when the impairment is reasonable in light of an important and legitimate public purpose, particularly where the state is regulating to protect the general welfare rather than acquiring benefits for itself.
Conclusion
The Court upheld Pennsylvania’s mine-subsidence regime against facial Takings Clause and Contracts Clause challenges, reasoning that the law served substantial public purposes, did not appropriate coal for public use, and left operators able to mine most of their coal such that no sufficiently severe, property-wide economic deprivation was shown.
