Section 2. A claimant shall not be entitled to compensation from the commonwealth for any incarceration or portion thereof, which was or will be credited toward a sentence for, or during which the claimant was also serving a concurrent sentence for the conviction of another crime. In those cases in which only a pardon from the governor is used to support a pending action against the commonwealth brought under this chapter, the subsequent exercise of the governor’s authority to revoke such pardon pursuant to section 152 of chapter 127 shall immediately negate the validity of any such pending action and the superior court shall immediately issue a summary judgment in favor of the commonwealth on such grounds.
