Take Care to Preserve Ordering and Option Rights
Client Alert | less than 1 min read | 02.23.11
In a 2-1 decision in Mabus v. Gen. Dynamics C4 Sys., Inc. (Feb. 4, 2011), the Federal Circuit held that GD was equitably estopped to void an order exercise by the government due to the wrong transmission method because it had repeatedly accepted that method during prior performance. The lesson for contractors is to scrutinize each order and option exercise and, if it is deficient in any way but is still desirable, to put the government on notice that it is being accepted despite the noted deficiency and without prejudice with regard to future exercises.

Eleventh Circuit Hears Argument on False Claims Act Qui Tam Constitutionality
On the morning of December 12, 2025, the Eleventh Circuit heard argument in United States ex rel. Zafirov v. Florida Medical Associates, LLC, et al., No. 24-13581 (11th Cir. 2025). This case concerns the constitutionality of the False Claims Act (FCA) qui tam provisions and a groundbreaking September 2024 opinion in which the United States District Court for the Middle District of Florida held that the FCA’s qui tam provisions were unconstitutional under Article II. See United States ex rel. Zafirov v. Fla. Med. Assocs., LLC, 751 F. Supp. 3d 1293 (M.D. Fla. 2024). That decision, penned by District Judge Kathryn Kimball Mizelle, was the first success story for a legal theory that has been gaining steam ever since Justices Thomas, Barrett, and Kavanaugh indicated they would be willing to consider arguments about the constitutionality of the qui tam provisions in U.S. ex rel. Polansky v. Exec. Health Res., 599 U.S. 419 (2023). In her opinion, Judge Mizelle held (1) qui tam relators are officers of the U.S. who must be appointed under the Appointments Clause; and (2) historical practice treating qui tam and similar relators as less than “officers” for constitutional purposes was not enough to save the qui tam provisions from the fundamental Article II infirmity the court identified. That ruling was appealed and, after full briefing, including by the government and a bevy of amici, the litigants stepped up to the plate this morning for oral argument.
