The U.S. Court of Appeals in March upheld a judge's decision last summer to dismiss three sexual abuse cases against Kevin Clash, the Dundalk native who served as the voice of Sesame Street's "Elmo" puppet.

In affirming the lower court's ruling, the appeals court said it "considered all the plaintiff's arguments relevant to the accrual of their claims under the discovery rule and find them to be without merit," according to court documents filed last week by Clash's lawyer, Michael G. Berger.

The initial ruling was made by a U.S. district judge in July 2013, at which time Berger, said his client was "pleased" with what he deemed "an important step" toward rehabilitating his image. Berger could not be reached for comment Wednesday. Clash resigned in November 2012.
