(2) (A) Prior to trial, the court shall determine if the defendant has mental retardation.

(ii) At the time the jury retires to decide mitigating and aggravating circumstances, the jury shall be given a special verdict form on mental retardation.
(iii) If the jury unanimously determines that the defendant had mental retardation at the time of the commission of capital murder, then the defendant will automatically be sentenced to life imprisonment without possibility of parole.
(C) If the court determines that the defendant has mental retardation, then:
(i) The jury is not "death qualified"; and
