More than 40 state attorney generals said Wednesday they plan to appeal the dismissal of their no-confidence lawsuit against Facebook by waging a lengthy legal battle to rein in Silicon Valley giants.

States will push for a decision by a federal judge last month that clarified their arguments that Facebook acquired a monopoly through the acquisition of Instagram and WhatsApp in 2014 and damaged competition. The judge said regulators’ attempts to break up the social media company came several years after the merger was approved.

Judge, James E. The “judge” of Bossberg, the court, has no knowledge of the case, and the plaintiffs provide nothing where there is such a long delay in finding such a result-oriented remedy, said Judge James E. Bossberg, a U.S. District Court judge for the District of Columbia. .

The state’s attorney general has 90 days from the date of notice to file an appeal, including his arguments.

Mr. Boasberg also rejected a similar complaint brought by the Federal Trade Commission, which criticized the agency’s monopoly claim, but directed the agency to rewrite its claim. The FTC is expected to file its case in court by August. 19. The states’ notice of the plan to appeal does not include new antitrust arguments and the United States Appeal was filed for the Columbia Circuit District.

Facebook has voiced lawsuits from state and federal regulators, saying most of the evidence used against the company was now presented to the FTC when the agency approved the merger years ago. The company argues that it does not have a monopoly, it will draw attention to the competition of Snap, Twitter and messaging applications.
