The criminal charges against Sen. Ted Stevens, R-Alaska, accused of filing false financial reports to obscure hundreds of thousands of dollars in gifts and home renovations, do not violate constitutionally protected legislative activity, a federal judge ruled Tuesday in dismissing an attack on the indictment.

Williams & Connolly lawyers, representing Stevens, argued in briefs and in court this month to Judge Emmet Sullivan of the U.S. District Court for the District of Columbia that government prosecutors improperly pitched protected legislative activity to grand jurors. Stevens, indicted on seven felony counts in July, has requested a speedy trial in the hope to clear his name before the November general election.
