The Hertz Corp. former general counsel Jeffrey Zimmerman has asked a New Jersey federal court to dismiss a lawsuit accusing him and two other ex-top executives of owing the rental car giant more than $200 million in legal fees and other costs related to misstating company income.

Zimmerman argued in a motion to dismiss filed in the U.S. District Court for the District of New Jersey on Thursday that his former employer failed to adequately allege its ex-top lawyer engaged in gross negligence and misconduct that forced the company to restate its financial statements in 2011, 2012 and 2013.
