Dozens of US state attorneys general filed an antitrust lawsuit in federal court against Google on Wednesday, according to an entry in the court docket.
The lawsuit was filed in the US District Court for the Northern District of California. The complaint was not immediately available.
The states have been expected to file a lawsuit saying that the search and advertising giant violates antitrust law in running Google Play Store, its app store for Android phones, according to sources familiar with the matter.
The lawsuit, one of a series that has been filed against Google in the United States, follows complaints about the Alphabet Inc. unit’s management of its app store, known as Play Store, even though the company was originally seen as more open than Apple.
Google bans apps with objectionable content from its store, and further requires that some apps use the company’s payment tools and pay Google as much as 30 percent of their revenue.
Those and related policies prompted criticism from app developers, particularly when Google said in September it would ramp up enforcement. Google Play Store is far more widely used than similar products from Amazon, Samsung, Huawei and others.
