(Francisco Kjolseth | The Salt Lake Tribune) House speaker Greg Hughes calls to order a special session to override Gov. Gary Herbert's vetoes of two bills. The issues at hand are both balance-of-power matters. One would allow the legislature to use its own attorneys to intervene in any court challenge of state law instead of relying on the attorney general. The second would establish legal methods to force the attorney general to provide the Legislature with legal opinions when requested.
