## Facts

- An industrial company owned a nineteenth-century villa classified as a protected cultural monument under Rhineland-Palatinate law.
- The owner sought permission to demolish the building; demolition required administrative approval.
- The challenged provision allowed demolition only if other public-interest requirements outweighed monument-protection interests.
- The statutory balancing test excluded the owner’s private interests and provided no mechanism to prevent or offset exceptionally severe burdens on the owner.
- After a demolition permit was denied, the Higher Administrative Court of Rhineland-Palatinate suspended proceedings and referred the constitutionality of the provision to the Federal Constitutional Court in a concrete norm control proceeding.

## Issues

1. Whether monument-protection rules defining the content and limits of property violate the constitutional property guarantee when they do not exclude disproportionate burdens and provide no safeguards to avoid them.
2. Whether a demolition-approval standard that bars consideration of the owner’s private interests is incompatible with the property guarantee.
3. Whether post hoc monetary compensation alone satisfies constitutional requirements, or whether the legal framework must prioritize avoiding or mitigating excessive burdens while preserving the property’s private utility.

## Decision

- The court declared the challenged demolition-approval provision incompatible with the constitutional guarantee of property.
- The court held that monument-protection regulations are unconstitutional if they permit disproportionate burdens on owners and lack arrangements to prevent such outcomes.
- The court rejected compensation schemes that merely grant a monetary claim, holding them insufficient where they do not first seek to prevent excessive burdens in practice.
- The court required a framework in which authorities, when applying property restrictions in individual cases, address the need for compensation at least in principle at the time the restriction is imposed.
- The court treated the challenged rule as a general regulation of the content and limits of property (not an expropriation), while stressing that severe restrictions nearing expropriatory intensity require constitutionally adequate mitigation and compensation mechanisms.

## Legal Principles

- The legislature may regulate the content and limits of property, but must respect proportionality and the constitutional protection of the substance and private utility of property.
- Monument protection is a legitimate and weighty public interest, but it cannot be pursued through rules that categorically disregard the affected owner’s situation.
- A regulatory scheme is constitutionally defective if it fails to exclude outcomes that impose extraordinary, owner-destroying burdens and provides no tools (exemptions, adjustments, or comparable measures) to prevent them.
- Money-only compensation mechanisms are inadequate where the constitutional property guarantee requires first-priority measures to avoid disproportionate burdens and preserve private utility as far as possible.
- Administrative decisionmakers must consider, alongside imposing a concrete restriction, whether compensation or other relief is required, rather than deferring the question indefinitely.

## Conclusion

The court invalidated a monument-protection demolition standard that weighed only competing public interests and ignored owner burdens, holding that property regulation must include workable safeguards to prevent disproportionate restrictions and cannot rely solely on delayed, monetary compensation.
