Obtained class certification status and successfully settled suit for a class of 60 retirees that had previously been employed by Celanese and who were improperly denied retiree medical benefits because they decided to defer retirement until after Celanese was purchased by KoSa Corporation, as successor in interest. The suit alleged that both corporations had made representations to the plaintiff class that they would be eligible for retiree health benefits if they remained employed during a transition period following the sale of Celanese to KoSa and asserted that defendants had breached their fiduciary duty under ERISA when these retirees were denied retiree health benefits.
