An appeals court has ruled that a state law that gives a $250 fee to the Tennessee Bureau of Investigation for each DUI conviction obtained using a blood or breath test is unconstitutional.
State lawmakers passed a TBI-backed proposal in 2010 to raise the fee from $100 to $250.
The ruling says the fees total about $3 million annually.
It's unclear if prosecutors will appeal to the state Supreme Court.
The case involves more than 20 defendants who provided blood or breath samples.
