Google Found Guilty of Antitrust Violations : After years of scrutiny and legal maneuvering, the U.S. District Court for the District of Columbia ruled in favor of the Department of Justice (DOJ) and state attorneys general in a major antitrust case against Google. The court found that Google maintained illegal monopoly power in the general search and search advertising markets by striking exclusive deals with major distributors—such as Apple, Mozilla, and Android device manufacturers—that gave it default search engine status. The ruling is considered one of the most significant victories for antitrust enforcement under Section 2 of the Sherman Act in recent decades.

In a landmark antitrust action against Google, the U.S. District Court for the District of Columbia sided with the DOJ and state attorneys general after years of litigation. Google’s exclusive relationships with Apple, Mozilla, and Android device manufacturers give it default search engine status, giving it illegal monopoly power in the general search and search advertising marketplaces, the court said. The verdict is one of the most significant Section 2 Sherman Act antitrust triumphs in recent decades.
What Happened
Many credit innovation and user experience for Google’s dominance in internet search since the early 2000s. After a year-long investigation, the DOJ and eleven state attorneys general sued Google on October 20, 2020, saying that it violated federal antitrust laws by creating exclusionary agreements to stifle competition. In a second lawsuit, 38 states accused Google of monopolizing more internet markets and excluding specialized vertical providers. After consolidation, both cases were tried in September–November 2023.
According to the claims, Google’s arrangements with device manufacturers made its search engine the default on a wide range of consumer gadgets. The contracts didn’t directly forbid users from switching search engines, but they drastically limited user exposure to Bing and DuckDuckGo, preventing genuine competition.
Google has held a dominant position in the online search market since the early 2000s, with much of its success initially credited to innovation and a superior user experience. However, after a year-long investigation, the U.S. Department of Justice (DOJ) and attorneys general from eleven states filed a lawsuit on October 20, 2020, accusing the company of violating federal antitrust laws through exclusionary agreements designed to suppress competition. Soon after, 38 additional states filed a separate lawsuit that expanded the claims to include monopolization of other online markets and exclusionary conduct aimed at specialized vertical providers (SVPs). These lawsuits were eventually consolidated, and the trial was held between September and November 2023. Central to the legal challenge were Google’s contracts with device manufacturers, which ensured that its search engine was set as the default option across a wide array of consumer devices. While these agreements did not outright prohibit users from switching to competing search engines, they effectively stifled competition by significantly limiting user exposure to alternatives like Bing and DuckDuckGo.
Court Finds Google’s Agreements Anticompetitive
Judge Amit Mehta concluded that Google’s business practices constituted exclusive dealing, a violation of Section 2 of the Sherman Act, by using contractual agreements to unfairly limit competition. According to the court, these agreements resulted in the foreclosure of 50% of the general search services market and 45% of the general search text advertising market, effectively blocking rival companies from gaining meaningful market access. This level of foreclosure, the court found, allowed Google to artificially preserve its monopoly, raise advertising prices, and stifle innovation, harming both competitors and consumers. In reaching this decision, the court relied on Brown Shoe Co. v. United States to define the relevant product markets and applied the framework from United States v. Microsoft Corp. to assess the exclusionary nature of Google’s conduct and its anticompetitive effects.
According to Judge Amit Mehta, Google’s contracts unfairly reduced competition, which is against Section 2 of the Sherman Act. The court said that these deals shut out other companies from 50% of the general search services market and 45% of the general search text advertising market. The court said that Google hurt rivals and customers by using foreclosure to protect its monopoly, raise advertising rates, and stop new ideas from coming up. The court used Brown Shoe Co. v. United States to describe the relevant product markets and United States v. Microsoft Corp. to look at Google’s actions that kept some businesses from competing with Google.
The Causation Debate: Lenient Standard Applies
A key part of the ruling was how the court addressed causation. Rather than requiring the strict “but-for” standard—proof that harm wouldn’t have occurred without Google’s conduct—Judge Mehta applied a more lenient test from the Microsoft case, allowing causation to be inferred if the conduct was “reasonably capable” of maintaining monopoly power. He rejected Google’s push for a stricter standard, arguing it would place unfair burdens on plaintiffs in complex digital markets. The judge even declined to rely on the DOJ’s detailed but-for analysis, reinforcing that such precision isn’t required under current antitrust law.
The court’s discussion of cause was an important part of the decision. As opposed to the strict “but-for” standard, which requires proof that harm wouldn’t have happened without Google’s actions, Judge Mehta used a less strict test from the Microsoft case, which said that action could be assumed to have caused harm if it was “reasonably capable” of keeping monopoly power. And he said no to Google’s request for a stricter standard, saying it would unfairly burden claimants in complicated digital markets. The judge didn’t even use the DOJ’s incredibly thorough but-for analysis, showing that such accuracy isn’t needed under current antitrust law.
Google to Appeal the Antitrust Ruling
Google has officially announced its intention to appeal the antitrust ruling, signaling that the legal battle is far from over. Although the company prevailed on a few minor points—such as avoiding court-imposed sanctions and not being compelled to open its platforms to competitors—the overall judgment dealt a substantial blow to Google’s market practices. The case now moves into a remedies phase, where the court will determine whether structural or behavioral changes are necessary to address the anticompetitive conduct. These changes could significantly impact how Google manages its search engine and advertising operations. In response to the ruling, Google stated, “We respectfully disagree with the court’s decision and intend to appeal. Our partnerships are entirely legal and improve the online experience for users.”
