An insurer remains on the hook for more than $1.7 million stolen from a company in a sophisticated phishing scam that involved a scammer posing as a London attorney, a split federal appeals court panel ruled Monday.

But only Judge William Pryor of the U.S. Court of Appeals for the Eleventh Circuit and visiting jurist Ronald Gilman agreed with the lower court that the commercial crime policy issued to the policyholder, Atlanta IT staffing and consulting firm Principle Solutions Group, “unambiguously” covered the loss.
