A Tennessee death row inmate is challenging the newly expanded authority of the appointed state attorney general to argue certain capital cases, a power that lawmakers shifted away from locally elected prosecutors under a new law after some expressed reluctance to pursue the death penalty.

The law passed in April by the GOP-led Tennessee Legislature and signed by Republican Gov. Bill Lee has generated opposition from attorneys and Democratic lawmakers. They say the change violates the state Constitution, bypasses the will of voters and targets progressive-minded district attorneys who have defied lawmakers in the past.
