A Manhattan Supreme Court decision denying certain defense arguments by Cadwalader, Wickersham & Taft has helped pave the way for a legal malpractice trial that could feature testimony from the owner of the Washington Redskins and M&A dealmaker Dennis Block.

The legal malpractice case against Cadwalader is in its seventh year. It was brought by Red Zone, a now-inactive investment vehicle run by Washington Redskins owner Daniel Snyder, alleging negligent legal advice.
