It looks like Dean Singleton has won the first round in his battle with Tony Ridder’s son, Par (pictured), who quit as publisher of Singleton’s St. Paul (Minn.) Pioneer Press to lead the Minneapolis Star Tribune. Singleton, CEO of MediaNews, claims Ridder took confidential data with him, and a judge yesterday (April 20) ordered the Star Tribune to allow Singleton’s people to examine its computers to see if they contained any of the disputed data. Singleton’s lawyers also convinced the judge to grant a temporary restraining order to stop one of the employees who followed Ridder from working for the competition. That employee was under a non-compete agreement. The next round is set for June 18. Coverage: AP, Business Journal, Pioneer Press and Star Tribune.
