Chief Judge Denise J. Casper of the U.S. District Court for the District of Massachusetts issued a preliminary injunction on Tuesday, April 21, 2026, striking down several Trump administration directives that had slowed the development of renewable energy projects on federal lands and waters. The ruling specifically targets a policy introduced by the Department of the Interior that mandated all solar and wind energy projects receive personal approval from Interior Secretary Doug Burgum. Judge Casper ruled that the plaintiffs, a coalition of clean energy developers, demonstrated a high likelihood of success on their claims that these administrative hurdles violate existing federal statutes and would cause irreparable harm without court intervention.
The contested policy was implemented by the Interior Department in July 2025. Under the directive, the standard delegated authority for project approvals was revoked, centralizing all final decisions under Secretary Burgum. Administration officials argued at the time that this enhanced oversight was necessary to rectify what they characterized as preferential treatment given to renewable energy technologies during the previous administration. However, the court found that this centralized approval process created an administrative bottleneck that threatened the timeline of multi-billion-dollar infrastructure projects.
A primary concern cited in the legal challenge was the timing of federal tax credits. Many wind and solar projects must meet specific construction milestones to qualify for credits under the Inflation Reduction Act and other federal programs. The plaintiffs argued that the delays caused by the secretarial approval requirement would cause projects to miss these deadlines, rendering them financially unviable. Judge Casper noted that the administration’s actions appeared to circumvent the intent of Congress in establishing these energy development frameworks, particularly regarding the promotion of domestic energy diversity.
This ruling represents a significant legal setback for the Trump administration’s broader energy agenda, which has prioritized the expansion of fossil fuel extraction on federal lands while rolling back incentives for green energy. The administration has frequently cited the need to protect grid reliability and reduce reliance on what it terms unreliable energy sources. Conversely, the ruling aligns with the efforts of several coastal states, particularly in the Northeast, that have integrated offshore wind into their long-term carbon reduction targets and regional economic development plans.
Following the ruling, the Department of Justice did not immediately indicate whether it would appeal the injunction to the U.S. Court of Appeals for the First Circuit. Representatives for the plaintiff coalition stated that the decision restores a predictable regulatory environment necessary for large-scale infrastructure investment. The Interior Department maintained in its filings that the Secretary possesses broad discretionary authority under the Outer Continental Shelf Lands Act and the Federal Land Policy and Management Act to oversee the use of public resources, though the court found that such authority does not supersede statutory mandates for timely project reviews.
