Eighth Circuit Deems Legal Threats a “Claim;” Regulation Requiring Prejudice Inapplicable [Global Insurance Alert]

February 02, 2015

On January 9, 2015, the U.S. Court of Appeals for the 8th Circuit handed down Philadelphia Consolidated Holdings Corp. v. LSI-Lowery Systems, Inc., which decided whether a technology company’s claim was covered under its professional liability policy. In LSI-Lowery, the court decided three issues of current importance for “claims made” policies. First, emails showing an expectation the insured would be sued meant that a “claim” had been made even though damages were not expressly demanded. Second, when it was made, the claim involved a “wrongful act,” even though it related to breach of a contract (an excluded circumstance). Third, a regulation mandating a finding of prejudice in order to prevail on “late notice” did not apply because there was no coverage under the policy in the first instance.

Service of Subpoenas on Syracuse University Seeking Evidence of Sexual Molestation is a “Claim” Giving Rise to Covered Defense Costs According to New York State Court [Professional Liability Alert]

March 20, 2013

In Syracuse University v. National Union Fire Insurance of Pittsburgh, PA, No. 2012EF 63 (Sup. Ct., Onondaga County, January 29, 2013), the New York Supreme Court, County of Onondaga, held that an insured’s costs incurred in responding to subpoenas issued by state and federal agencies, were covered (as defense costs) as “Claims” made under a not-for-profit individual and organization insurance policy issued by National Union. The case arose out of allegations that a Syracuse assistant basketball coach, Bernie Fine, had sexually abused two former participants in Syracuse University’s basketball program over a period of years while serving in his capacity as the University’s assistant basketball coach.1 The court held that issuance of the subpoenas constituted a “Claim” as defined in the policy.
