Michael Hausfeld hasn’t wasted any time responding to a juicy wrongful termination suit filed by one of his former law partners, Jon King, who says he was canned after speaking out about a raft of alleged ethics violations at Hausfeld’s eponymous Washington, D.C., antitrust class action firm, Hausfeld LLP.

On Jan. 18—one day after the case was filed—Hausfeld filed a motion to seal the complaint on the grounds that it “alleges irrelevant, sensitive information about the firm for the apparent purpose of diminishing the firm’s reputation within the legal community in hopes of leveraging a settlement, or otherwise exacting revenge.” And on Tuesday Hausfeld moved to dismiss the suit entirely, arguing that King agreed to arbitrate any employment-related grievances. Daniel Hoffer of Venable filed both motions for Hausfeld.
