As Governor Roy Romer's insurance commissioner in the mid-'90s, Jack Ehnes was a local consumers' hero, always fighting for the little guy. Although most of his innovative reforms have since been undone, he's still in there pitching for Colorado consumers -- albeit indirectly. As chief executive officer of the California State Teachers Retirement System, the third-largest public pension fund in the nation, Ehnes is part of the group's lawsuit against Qwest Communications, its founder Phil Anschutz, former chief executive Joseph Nacchio and several investment-banking companies. The suit, filed in December, accuses them of engaging in fraudulent schemes that cost California teachers $150 million from investments in Qwest stocks and bonds. The defendants deny the claims. Welcome back, Jack.
