SALT LAKE CITY — Utah's attorney general is investigating the Bowl Championship Series for a possible violation of federal antitrust laws after an undefeated Utes team was left out of the national title game for the second time in five years.

Attorney General Mark Shurtleff contends the BCS unfairly puts schools like Utah, which is a member of a conference without an automatic bid to the lucrative bowl games, at a competitive and financial disadvantage.

The BCS is designed to pit the top two teams against each other in a national championship game each year. It uses a complicated formula based on human polls and computer rankings to determine who plays in that game, which Shurtleff contends is biased.
