The Colorado Supreme Court has decided not to hear a lawsuit from state Treasurer Walker Stapleton seeking information about employee benefits in the state's pension system.

The court issued its decision Monday. Stapleton had appealed to the state's highest court after two lower courts ruled against him.

Stapleton, a Republican, has sought non-identifying information about the top 20 percent of the pension's beneficiaries and their annual retirement benefit. He says the information would help him to assess the health of the state pension's program and how to keep it solvent.

The pension board that manages the Public Employees Retirement Association has maintained that the information is confidential.
