Parker Drilling Management Services v. Newton

Updated Sep 18, 2026

In brief

The Supreme Court sent Parker Drilling back to the Ninth Circuit, deciding that state law fills gaps in federal law but does not replace federal rules that already cover the issue.

Where it stands

What it’s about
This case asked whether California wage-and-hour rules applied to workers on offshore drilling platforms on the Outer Continental Shelf, where federal law generally controls.
Who it affects
State law can apply on the Outer Continental Shelf only when federal law leaves a gap. Claims based on California's standby-pay and minimum-wage rules fail to the extent federal law already covers those issues, while other claims remain unresolved.

What it's about

The Court held that state law can be adopted there only to fill a gap in federal law, not whenever the state rule relates to the dispute.

The Outer Continental Shelf Lands Act (OCSLA) sets rules for when state law can fill gaps in federal law on offshore areas under federal control.

Question presented

Whether, under OCSLA, state law is borrowed as the applicable federal law only when there is a gap in the coverage of federal law, as the Fifth Circuit has held, or whenever state law pertains to the subject matter of a lawsuit and · is not preempted by inconsistent federal law, as the Ninth Circuit has held.

What the Court decided

Holding

Under the proper standard, some of Newton’s present claims can be resolved, though others have not been analyzed by the Ninth Circuit. Some claims are premised on the adoption of California law requiring payment for all standby time. Because federal law already addresses this issue, California law does not provide the rule of decision on the OCS. To the extent Newton’s OCS-based claims rely on that law, they necessarily fail. Likewise, to the extent his OCS-based claims rely on the adoption of California’s minimum wage, the FLSA already provides for a minimum wage, so the state minimum wage is not adopted as federal law and does not apply on the OCS. 881 F. 3d 1078 and 888 F. 3d 1085, vacated and remanded.
