WASHINGTON, AP – A US federal judge has dismissed antitrust lawsuits brought against Facebook by the Federal Trade Commission and a coalition of state attorneys-general, dealing a significant blow to attempts by regulators to rein in tech giants.

US District Judge James Boasberg ruled on Monday that the lawsuits were “legally insufficient” and didn’t provide enough evidence to prove that Facebook was a monopoly.

The ruling dismisses the complaint but not the case, meaning the FTC could refile another complaint.

“These allegations – which do not even provide an estimated actual figure or range for Facebook’s market share at any point over the past 10 years – ultimately fall short of plausibly establishing that Facebook holds market power,” he said.

The US government and 48 states and districts sued Facebook in December 2020, accusing the tech giant of abusing its market power in social networking to crush smaller competitors and seeking remedies that could include a forced spin-off of the social network’s Instagram and WhatsApp messaging services.

The FTC had alleged Facebook engaged in a “a systematic strategy” to eliminate its competition, including by purchasing smaller up-and-coming rivals like Instagram in 2012 and WhatsApp in 2014.

New York Attorney General Letitia James said when filing the suit that Facebook “used its monopoly power to crush smaller rivals and snuff out competition, all at the expense of everyday users.”

Boasberg dismissed the separate complaint made by the state-attorneys general as well.

The FTC didn’t immediately have a comment on the ruling and it wasn’t known whether the agency planned to try again.

Facebook, in an emailed statement, said: “We are pleased that today’s decisions recognise the defects in the government complaints filed against Facebook. We compete fairly every day to earn people’s time and attention and will continue to deliver great products for the people and businesses that use our services.”

Alex Harman, competition policy advocate for Public Citizen, a consumer advocacy group, said the ruling wasn’t surprising in that other courts had grappled with and thrown out cases in which consumers weren’t charged directly for the services in question.

“Courts really have a hard time with that market definition for some reason,” Harman said. “It’s Exhibit A for why we need the laws changed.”

An ambitious package of legislation to overhaul the antitrust laws, which could point toward breaking up Facebook as well as Google, Amazon and Apple, was approved by the House Judiciary Committee last week and sent to the full US House.
