German Bundesgerichtshof (Federal Supreme Court) Provides Guidance on the Definition of the De Minimis Clause in Determining Whether a Merger Is Subject to German Merger Control

Client Alert | 2 min read | 12.17.07

Last Friday, in a controversial and long-awaited decision, the German Bundesgerichtshof clarified the de minimis merger filing exception in Germany. In Germany, merger filings are required if the thresholds are met and the concentration has an impact on the market unless the market affected by the merger is a de minimis market. What constitutes a de minimis market has been the subject of considerable debate. In its judgment the Bundesgerichtshof clarifies the so-called “minor market clause” (section 35 (2), no. 2 Act against Restraints of Competition (“ARC”)).

In order to be considered de minimis, two factors must be met. First, the affected market must be one in which goods or commercial services have been offered for at least five years. By requiring the market to be in existence for at least five years, newly developed and still expanding markets are subject to German merger control. Second, in order for a merger to be exempt from German merger control under the de minimis exception, the annual sales volume for the relevant market must have been less than € 15 million in the previous calendar year. Since July 1, 2005, the German Federal Cartel Office (Bundeskartellamt) has interpreted this second requirement rather broadly, taking the position that the relevant market, for purposes of determining sales volume, may -  as the case may be - extend beyond Germany.

Based on this interpretation, the Bundeskartellamt prohibited a concentration between Du Pont and Pedex & Co. GmbH because the total market turnover exceeded the sales volume threshold. The first instance court (Higher Regional Court of Düsseldorf), however, overturned this decision and held that, for the purpose of the de minimis or “minor market clause,” the geographical scope of the market can only extend to Germany. The Bundeskartellamt subsequently appealed this decision.

The Bundesgerichtshof upheld the decision of the Higher Regional Court of Düsseldorf. As in previous decisions, the Bundesgerichtshof upheld the practice of bundling groups of minor product markets together provided that the products are close neighbours (supply side substitutable), the market players are largely the same and the products are sold through the same distribution channel.

The Bundesgerichtschof decision has not yet been published.

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....
