SAN FRANCISCO — The discipline originally proposed for one of California’s top plaintiff lawyers just wasn’t tough enough for the Ninth Circuit U.S. Court of Appeals.

Walter Lack received a six-month suspension from practicing before the Ninth Circuit due to fraudulent appellate briefs his firm filed in litigation against Dole Food Co. The penalty handed down today is greater than the one recommended by the court’s own independent prosecutor, and it puts the Engstrom, Lipscomb & Lack partner in a tricky posture vis-a-vis the State Bar.
