MediaNews Group and Hearst are arguing in court papers that San Francisco businessman Clint Reilly (left) doesn’t have the right to sue them in order to stop their plans to consolidate newspaper operations in the Bay Area. The Bay Guardian ran an editorial this week that explains this tactic and argues against it. Reilly’s case goes to trial April 30, unless U.S. District Judge Susan Illston agrees with this new argument advanced by the two newspaper companies.
