The litigation in Hornbeck Offshore Services, L.L.C. et al. v. Salazar arose after the 2010 Deepwater Horizon disaster, when an offshore rig explosion killed 11 workers and caused a major oil spill in the Gulf of Mexico. In response, the U.S. Department of the Interior, under Secretary Ken Salazar, issued a six-month moratorium on certain deepwater drilling operations in waters deeper than 500 feet. The suspension was formalized in the May 28, 2010 directive and followed by Notice to Lessees No. 2010-N04. It affected 33 permitted wells using floating rigs and restricted the issuance of new deepwater drilling permits. Hornbeck Offshore Services and other Gulf Coast marine, service, and fabrication companies sued in the Eastern District of Louisiana, arguing that the moratorium was arbitrary and capricious under the Administrative Procedure Act (APA) and lacked a sufficient administrative record. The plaintiffs also brought claims under the Outer Continental Shelf Lands Act (OCSLA), although the preliminary injunction analysis centered on the APA.
U.S. District Judge Martin Feldman granted a preliminary injunction on June 22, 2010, finding that the plaintiffs had shown a likelihood of success on their APA challenge because the agency had not adequately explained the connection between the Deepwater Horizon incident and a broad suspension of covered deepwater drilling operations. The court also questioned the government’s presentation of expert input for the moratorium and considered the economic effects on Gulf Coast energy, maritime, and related service businesses. After the Interior Department issued a second moratorium shortly after the injunction, Hornbeck argued that the agency had failed to comply with the court’s order. The district court later found the government in civil contempt and awarded attorney’s fees, but the Fifth Circuit reversed the contempt finding and vacated the fee award. Appellate proceedings over the moratoria were ultimately deemed moot after the challenged drilling suspensions were replaced or rescinded, leaving Hornbeck as a significant administrative law dispute over emergency agency action, administrative record review, and federal regulation of offshore energy operations.
The Deepwater Horizon drilling rig exploded in the Gulf of Mexico while workers were preparing to temporarily abandon a well. BP was the lease operator, and Transocean owned and operated the rig. The explosion killed 11 workers, caused the rig to sink two days later, and led to a massive uncontrolled oil spill. In response, the President directed Interior Secretary Ken Salazar to review offshore drilling safety and recommend measures for operations on the Outer Continental Shelf.
After Secretary Salazar’s report, Increased Safety Measures for Energy Development on the Outer Continental Shelf, the Department of the Interior issued a directive imposing a six-month suspension on certain deepwater drilling operations. Notice to Lessees No. 2010-N04 applied to drilling operations in water depths greater than 500 feet, affected 33 permitted wells using floating rigs, and restricted new deepwater drilling permits. The report’s executive summary referred to peer review, but several National Academy of Engineering reviewers later stated that they had reviewed safety recommendations and had not endorsed the broad drilling moratorium.
Hornbeck Offshore Services and other Gulf Coast marine, service, and fabrication companies filed suit in the U.S. District Court for the Eastern District of Louisiana. The plaintiffs argued that the moratorium was arbitrary and capricious because the agency had not adequately explained why the Deepwater Horizon disaster justified a broad suspension of covered deepwater drilling operations. The lawsuit raised claims under the Administrative Procedure Act (APA) and the Outer Continental Shelf Lands Act (OCSLA), although the preliminary injunction ruling centered on the APA.
Judge Martin L.C. Feldman granted a preliminary injunction barring enforcement of the May 28 moratorium and Notice to Lessees No. 2010-N04. The court found that the plaintiffs had shown a likelihood of success on their APA challenge because the agency record did not adequately connect the Deepwater Horizon incident to the full scope of the drilling suspension. The opinion also questioned the government’s presentation of expert input and considered the economic effects on Gulf Coast businesses tied to offshore drilling, vessel services, fabrication, and related work.
After the preliminary injunction, the Interior Department issued a second moratorium with revised findings and additional explanation. The second directive replaced the first moratorium and was presented as a new agency action. Hornbeck argued that the second moratorium and related agency conduct continued the practical effect of the suspended policy. The district court later treated the government’s actions as relevant to compliance with the preliminary injunction, although later appellate proceedings limited the effect of that finding.
The U.S. Court of Appeals for the Fifth Circuit dismissed the government’s appeal from the preliminary injunction as moot because the first moratorium had been superseded by the second moratorium. The ruling did not produce a final merits decision on whether the first moratorium was lawful. The mootness ruling left unresolved broader questions about voluntary cessation and judicial review of short-lived emergency agency actions.
Judge Feldman later found the Department of the Interior in civil contempt for failing to comply with the preliminary injunction. The district court cited public statements and agency conduct that, in its view, continued the practical effect of the enjoined moratorium. The plaintiffs were initially awarded more than $530,000 in attorney’s fees and costs. The Fifth Circuit later reversed the civil contempt finding and vacated the related fee award, concluding that the preliminary injunction did not clearly bar the government from issuing a new moratorium supported by a revised explanation.

Offshore Drilling and Petroleum Engineering Expert Witnesses
Offshore drilling and petroleum engineering testimony can be central in disputes involving oil rig safety, well design, well-control systems, and blowout prevention. In Hornbeck, the court evaluated Interior’s decision to halt operations on 33 active wells using floating rigs in water depths greater than 500 feet. Technical analysis of rig integrity, well-control safeguards, and accepted offshore drilling practices would have helped frame whether a broad deepwater drilling moratorium was supported by the safety concerns identified after Deepwater Horizon.
Engineering Expert Witness
Engineering testimony may also apply to offshore drilling disputes involving equipment performance, operational risk, blowout prevention systems, and deepwater rig safety. In Hornbeck, the moratorium followed the Deepwater Horizon blowout and applied to certain deepwater drilling operations involving floating rigs in waters deeper than 500 feet.
Economic Expert Witness
Economic experts with regional-industry experience are often consulted to assess the financial consequences of federal regulatory actions. Judge Feldman’s ruling cited significant economic harm to Gulf Coast communities, referencing job losses and disruptions in vessel support services. These experts typically provide analysis on how agency decisions affect employment, domestic energy production, and supply chains.
Civil Litigation Expert Witness
Civil litigation testimony may be relevant when a dispute turns on court-order compliance, injunction scope, and civil contempt. In Hornbeck, the district court found the Department of the Interior in civil contempt and awarded more than $500,000 in fees and costs. The Fifth Circuit later reversed the contempt finding and vacated the related award.
Challenge the Procedural Basis of Agency Action Under the APA
Attorneys should examine whether a federal directive rests on a reasoned explanation and a clear administrative record, especially in claims brought under the Administrative Procedure Act (APA). In Hornbeck, the district court found at the preliminary injunction stage that the plaintiffs were likely to succeed on their APA challenge because the agency had not adequately connected the Deepwater Horizon disaster to the broad drilling suspension. Procedural gaps, unsupported assumptions, or inaccurate descriptions of technical review can support a request for injunctive relief.
Use Injunctive Relief to Address Overbroad Regulatory Actions
Preliminary injunctions can be effective when a challenged agency action creates immediate economic or operational harm. In Hornbeck, the plaintiffs temporarily blocked enforcement of the first federal moratorium by arguing that the record did not show a rational connection between the safety concerns and the full scope of the suspension. A strong motion should tie the legal defect to concrete harm, including business interruption, contract disruption, and regional economic effects.
Tie Contempt Arguments to the Exact Scope of the Court Order
Post-injunction agency conduct can become central when a party argues that a court order was not followed. In Hornbeck, the district court relied on public statements and agency actions when it found civil contempt. The Fifth Circuit later reversed that finding and vacated the related fee award, concluding that the preliminary injunction did not clearly bar the government from issuing a new moratorium supported by a revised explanation. The decision points to the need for contempt arguments to track the precise language and limits of the injunction.
Quantify Regional Economic Harm with Expert Analysis
Economic impact analysis can help establish irreparable harm in challenges to high-impact regulatory action. In Hornbeck, Gulf Coast businesses tied to offshore drilling, vessel services, fabrication, and support operations argued that the moratorium caused immediate financial disruption. Attorneys should develop evidence of job losses, contract interruptions, idle equipment, and supply-chain effects when seeking emergency relief.
Test the Reliability and Use of Technical Review
An agency’s reliance on technical input should be checked against what the reviewers actually evaluated or endorsed. In Hornbeck, the court questioned the government’s presentation of National Academy of Engineering reviewers because several reviewers stated that they had not endorsed the broad drilling moratorium. Attorneys should verify whether cited technical sources truly support the agency action at issue and whether the administrative record accurately describes the scope of the review.
Hornbeck v. Salazar followed the federal government’s emergency response to the Deepwater Horizon disaster and tested the administrative record behind a six-month deepwater drilling moratorium. The district court blocked the first moratorium at the preliminary injunction stage, the Interior Department issued a second moratorium, and the Fifth Circuit later dismissed the first injunction appeal as moot after the original directive was replaced. The later contempt dispute narrowed the case further: although the district court found the government in civil contempt and awarded fees, the Fifth Circuit reversed that ruling because the preliminary injunction did not clearly prohibit the Interior Department from issuing a new moratorium supported by a revised explanation.
