Suit Against Quattrone to Be Tried in Calif.

Former Credit Suisse First Boston Corp. banker Frank Quattrone, who had a mistrial declared in a U.S. criminal trial, couldn’t keep a California investor suit accusing him of unfair business practices out of state court.

A federal judge transferred the case to state court, where it will be tried under California law. Lawyers for Quattrone and CSFB had moved the case to federal court, where investors must show they were intentionally misled to win.
