MONTGOMERY, Ala. - The majority of the Alabama Supreme Court on Dec. 28 determined that a potentially responsible party (PRP) letter from the U.S. Environmental Protection Agency constitutes a suit under an insured's insurance policies because the PRP letter is the functional equivalent of a suit filed in a traditional court of law (Travelers Casualty and Surety Co., et al. v. Alabama Gas Corp., No. 1110346, Ala. Sup.; 2012 Ala. LEXIS 174).
