Bay Guardian editor Tim Redmond reports that his newspaper has sued the New Times chain and its local papers, the SF Weekly and East Bay Express, for violating U.S. antitrust laws and California’s Business and Professions Code. Specifically, the Guardian claims New Times is selling ads at below cost, forcing the Bay Guardian to do the same. Eventually the Guardian’s pockets will run out of money faster than New Times, and that’s unfair, or at least that’s how the legal theory goes.
