MONTGOMERY, Ala. (AP) - State officials are working with a law firm to try and determine the median household income in Alabama, which could determine the salaries of state lawmakers in the coming year. A constitutional amendment approved by state voters in 2012 ties lawmakers' pay to the state's median household income starting next year. The Montgomery Advertiser reports that the amendment did not specify exactly how that should be measured, but tasks the Alabama's Personnel Department with determining it. The Personnel Department has entered into a $72,000 contract with Birmingham-based Baker Donelson Bearman to handle legal services and determine the median household income in the state. The contract is for one year. The Montgomery newspaper reports that its messages left with Baker Donelson and Campbell were not returned.
