22-6-5.1. Double sentence for crime by prisoner-Exception.
A court may sentence any person convicted of a crime committed while that person was a prisoner as defined by §22-11A-1, to a term of not more than twice the maximum term allowed by the statute for the commission of the same crime by a person not so confined. However, the provisions of this section do not apply if, for the same offense, the prisoner is subject to an enhanced penalty as an habitual offender.
