The Delaware Supreme Court has rejected a former Rite Aid Corp. executive’s bid to use a collateral attack on a final ruling to extend the period in which he could recover attorney fees from his former employer.

On Wednesday, an attorney for Franklin Brown, Rite Aid general counsel and executive vice president of the drugstore chain, pushed the court to view the challenge as a “further step” in his criminal fraud case, rather than a procedural exercise, separate from his core direct appeal to the nation’s high court.
