A Manhattan-based federal appeals court has revived a suit against Fox News Network by the parents of Seth Rich, a Democratic National Committee staffer whose murder touched off a conspiracy theory that eventually amounted to a “campaign of emotional torture” against the family, according to their complaint.

A three-judge panel of the appeals court ruled Friday that Joel and Mary Rich could proceed with intentional infliction of emotional distress claims against the network, a reporter and a frequent guest and political operative, who were responsible for publishing a retracted story that linked their son to DNC data published by WikiLeaks.
