(CNN) A federal judge on Thursday upheld a federal indictment against the Russian troll farm accused of meddling in the 2016 election, handing a victory to special counsel Robert Mueller.

In a 32-page opinion, Judge Dabney Friedrich rejected efforts by Concord Management and Consulting to dismiss the indictment, which accused the Russian company of conspiring to defraud the US government. Mueller's team says the company was involved in a well-funded "troll farm" that pumped out political propaganda to millions of Americans throughout the 2016 presidential campaign.

It was the second time that Friedrich, a Trump appointee, sided with Mueller and let the case proceed. Earlier this year , she rebuffed Concord's arguments that there were constitutional problems with Mueller's appointment and authority. Thursday's ruling centered more on the merits of the indictment.

Concord was charged with conspiring to defraud the US government by hiding its election-related activities and failing to register as a foreign agent trying to influence the US political process. The company wasn't charged with violating these laws, a point Concord made in its arguments.

But in upholding the indictment, Friedrich wrote that "the key question" was not whether Concord violated the underlying US laws that regulate foreign agents and political spending. Instead, she said the threshold to indict Concord on the conspiracy charge was whether the company's actions were "deceptive and intended to frustrate the lawful government functions" of the relevant agencies.
