A new lawsuit in the Jay Peak saga uses a legal theory that plaintiffs counsel says is untested in Florida state court: If a financial institution touches money, even for a second, it must try to make sure it isn’t being used for fraud.

Jonathan Feldman of Perlman, Bajandas, Yevoli and Albright in Miami filed the case June 3 against Raymond James Financial Inc. on behalf of several immigrant investors in the Jay Peak projects in Vermont, which included ski resort improvements and a biotech plant.
