Who interprets federal pay rules

Lesko v. United States

Updated Nov 12, 2026

In brief

Where it stands
Petition Pending

Awaiting an order on the petition

No decision timeline until the Court agrees to hear the case.

What it’s about
Jillian Lesko has filed a petition asking the Supreme Court to review the Federal Circuit’s 7–4 ruling that courts must use the Office of Personnel Management’s definitions of terms in the Federal Employees Pay Act, even when they conflict with longstanding court interpretations.
What's at stake
The petition asks whether courts must use OPM’s FEPA definitions in Lesko’s case; the Supreme Court has not resolved that question.

Summary: written with AI from the case record.

What it's about

She argues that the law’s general rulemaking provision does not give the agency that power under Loper Bright.

FEPA authorizes OPM to issue regulations needed to administer the law, and the dispute is whether that authority lets OPM require courts to use its definitions.

Question presented

Under this Court’s decision in Loper Bright, does the general rulemaking provision in 5 U.S.C. § 5548(a) delegate authority to OPM to authoritatively interpret FEPA, such that courts must adopt OPM’s definitions?

What happens next

The Court must decide whether to hear the petition. No argument or decision window exists before the Court agrees to review it.
