NASHVILLE (AP) - Sara Kyle has resigned from the board of the Tennessee Regulatory Authority, citing the panel's diminished role under a restructuring of the agency by Republican Gov. Bill Haslam.

Kyle was elected to the Public Service Commission in 1994. She was appointed as one three members of the agency when it was converted into the TRA two years later.

Haslam last year expanded the board to five members but made the panel part-time. Kyle said in a statement that the reduced time and staff has limited the agency's ability to "render fair and just decisions."

Kyle, who previously served as a Memphis judge, is married to Democratic Senate Minority Leader Jim Kyle.
