They pulled this here in Nebraska. It stalled several executions for two more years. Two more years these parasites fed on our society. The pretext was racial discrimination (isn't it always?) in the application of the death penalty. Even now, after a study found no evidence of racial bias, the quibbling continues over the method (Nebraska is the only state to still use "Ole Sparky" -- the electric chair).
We've got four clowns on The Row for multiple murders during a failed bank robbery in Norfolk a year and a half ago. But there are doubts they'll ever see the hangman (or the electrician, to be precise).
The race card is exactly some of the basis for their argument now. From what I've read the last few weeks on this, they want to bring diversity to the justice system.
