"This is a significant victory for Google, knocking out several claims and narrowing the range of activities at issue for trial," David Olson, a law professor at Boston College, told The Washington Post.

The ruling comes in one of two federal antitrust cases filed against Google (both civil,  not criminal, cases). The first was filed in 2020 and concerns the company's search business. The second was filed early this year and concerns Google's advertising business.

Both were filed in conjunction with multiple state attorneys general. "While the DOJ and states originally filed [the 2020 cases] separately, the suit has since become mostly consolidated," notes The Verge.

DOJ and the states accused Google of numerous forms of anti-competitive behavior. Mehta dismissed four of the lawsuit's claims and allowed three to move forward.

One of the claims dismissed relates to Google's treatment of "Specialized Vertical Providers," or SVPs, which the judge describes as "companies focused on niche markets—like Expedia or Tripadvisor for travel, OpenTable for restaurant reservations, and Amazon or eBay for shopping." The states say Google unlawfully limits the visibility of SVPs on Google's search results page, and that this and Google's data terms for SVPs weaken their position and harm search and search-advertising competition. But "plaintiffs' theory of anticompetitive harm rests on a multi-linked causal sequence that relies not on evidence but almost entirely on the opinion and speculation of its expert, Professor Jonathan Baker," noted the judge. "Remarkably, not one of Professor Baker's opinions, on which these fact assertions are based, cites to any record evidence."

One of the claims that can go forward relates to the company making Google the default search engine on Android phones. This claim seems especially silly, given that many people enjoy having some presets (like a default browser, search engine, etc.) come on their phones and Android users can easily change their default search engine if they wish to do so.

The government is literally making a federal case out of the fact that consumers might have to take less than five minutes to switch their default search engine settings if they don't want Google as their default search.

But this wouldn't be the first time the federal government has gotten weirdly in a tizzy over default tech settings. Part of the government's big antitrust case against Microsoft in the '90s and early 2000s was over the company bundling its Internet Explorer browser with its Windows desktop software.

Mehta's ruling that some of the government's claims against Google must go to trial "sets the stage for the first major tech monopoly trial since the federal government took Microsoft to court in the 1990s," notes The New York Times.

The trial is scheduled to begin on September 12.
