Less than a week after a group of retired Dewey & LeBoeuf partners appeared to pave the way for the swift approval of the defunct firm’s proposed Chapter 11 liquidation plan by settling a dispute with the Dewey estate, fresh resistance to a key component of that plan has emerged in the form of objections raised by six former Dewey partners.

In a series of filings made ahead of a Wednesday deadline, the former partners in question—two individuals and a pair of two-person teams—argue that U.S. Bankruptcy Judge Martin Glenn should not approve the Chapter 11 plan, which serves as a blueprint for how the Dewey estate expects to dispose of its assets in order to pay off creditors who say they are owed a combined total of some $600 million.
