Frankfort, Ky. ? The state’s highest court suspended three lawyers Thursday over questions about how they divided a $200 million settlement over the fen-phen diet drug.

The ruling by the Kentucky Supreme Court came after a lower court judge found that the Lexington lawyers breached their duty to about 440 clients they represented against drugmaker Wyeth.

The plaintiffs were among tens of thousands who sued Wyeth, which pulled the fenfluramine half of fen-phen off the market in 1997 amid reports that some users had heart valve damage and a few had a deadly lung condition. Fen-phen was never an FDA-approved combination.

The clients of William Gallion, Shirley Cunningham Jr. and Melbourne Mills received about $45 million in a 2001 settlement. The rest was split among attorneys and consultants, according to Linda Gosnell, chief counsel for the Kentucky Bar Assn.
