Major League Baseball cannot hide behind its antitrust exemption to fend off a lawsuit from fans who say the league unjustly dictates television markets for its ballclubs, a judge says.

U.S. District Judge Shira A. Scheindlin's ruling came after two lawsuits were brought by fans against MLB and the National Hockey League to stop their strict control over television broadcast rights.

The judge wrote that exceptions to antitrust laws are to be construed narrowly and noted that the U.S. Supreme Court has "expressly questioned the validity and logic of the baseball exemption and declined to extend it to other sports."
