Common Questions
Can the Fifth Amendment be used to block a data centre moratorium?
Developers are actively using the Fifth Amendment's regulatory-takings doctrine to challenge moratoriums. RCM Hill LLC filed a $100 million suit against Hill County Texas; the county rescinded its moratorium seven days later, though the lawsuit continues.Source: RCM Hill LLC v Hill County filing
What is a regulatory taking under the Fifth Amendment?
A regulatory taking occurs when a government law or order so restricts property use that it effectively deprives the owner of economic value without direct seizure. Courts apply the LUCAS or Penn Central tests to determine whether compensation is owed.Source: US constitutional law: Lucas v South Carolina Coastal Council; Penn Central Transportation Co v New York City
Did Hill County repeal its data centre moratorium because of a lawsuit?
Hill County voted unanimously on 4 June 2026 to rescind its moratorium, seven days after RCM Hill LLC filed a $100 million Fifth Amendment suit over its 1,235 MW Project Aquila campus. The lawsuit remains active and the developer still seeks damages.Source: Hill County public record / RCM Hill LLC filing
Is the DOE's Section 202(c) curtailment order a constitutional taking?
Parties challenging the DOE's Order 202-26-06 filed a rehearing on 28 May 2026 arguing it constitutes both a physical and regulatory taking. Courts have historically upheld emergency curtailment as settled regulatory power; resolution is not expected before 2027.Source: DOE 202(c) rehearing filing

Background

The Fifth Amendment's Takings Clause ("nor shall private property be taken for public use, without just compensation") has emerged in 2026 as the central constitutional instrument used by data-centre developers to challenge government moratoriums. The doctrine covers both direct physical takings and regulatory takings, where a law or order so restricts property use that it effectively seizes economic value without compensation. Two concurrent actions are testing this doctrine's reach: RCM Hill LLC's $100 million federal lawsuit against Hill County, Texas over the moratorium on its 1,235 MW Project Aquila campus , and a rehearing challenge filed on 28 May 2026 arguing the DOE's Section 202(c) curtailment order constitutes a physical and regulatory taking of backup-generation assets.

Regulatory takings law in the US has two main standards: the categorical LUCAS test (regulations that eliminate all economic value are per se takings) and the multi-factor Penn Central test (weighs economic impact, interference with investment-backed expectations, and the Nature of the government action). Courts have historically upheld emergency grid curtailment as settled regulatory power. The Hill County situation is more novel: a local legislature enacting a moratorium specifically targeting a single named class of industry has weaker precedent protection.

Hill County voted unanimously to rescind its moratorium on 4 June 2026, seven days after RCM Hill filed the suit, a pattern regulators and developers elsewhere will note. RCM Hill's lawsuit remains active; the developer still seeks damages and a court declaration, meaning the underlying constitutional question will proceed regardless of the repeal.
