SIOUX FALLS, S.D. - Although an insured's complaint states a bad faith claim that is plausible on its face, the bad faith allegations are vague enough to make a response by the defendant insurer difficult, a South Dakota federal judge ruled Aug. 5 (Henry Carlson Co. v. Arch Insurance Company, et al., No. 13-4133, D. S.D., Southern Div.; 2014 U.S. Dist. LEXIS 106993).
