New York lawyers representing plaintiffs in breast implant litigation gave no more than a lukewarm endorsement to a $3.2 billion settlement plan currently under review by a bankruptcy judge in Bay City, Mich.

U.S. Bankruptcy Judge Arthur J. Spector began a hearing Monday to weigh the fairness of a plan formulated by Dow Corning Corporation, the dominant maker of silicone breast implants. The hearing is expected to proceed, with interruptions, until the end of July.
