A malpractice case against 450-lawyer Drinker Biddle & Reath has a chance to refine a New Jersey Supreme Court doctrine that disallows legal malpractice claims after the underlying case settles.

The justices held last year in Puder v. Buchel, 183 N.J. 428, that a matrimonial client who settled a botched case and told the judge she was satisfied couldn’t pursue a malpractice claim for additional relief from the allegedly errant lawyer.
