SECTION 1. Section 10G of chapter 269, as appearing in the 2018 Official Edition, is hereby amended by striking out, in lines 36 and 37, the words “have the meaning set forth in section 121 of chapter 140” and inserting in place thereof the following words:- shall mean any crime punishable by imprisonment for a term exceeding 1 year that: (i) has an element the use, attempted use or threatened use of physical force or a deadly weapon against the person of another; (ii) is burglary, extortion, arson or kidnapping; or (iii) involves the use of explosives.

SECTION 2. Said section 10G of said chapter 269, as so appearing, is hereby amended by adding the following sentence to the end thereof:- (f) For purposes of this section, any type of juvenile adjudication shall not be considered a prior conviction and shall not be used as a prior predicate conviction that triggers, when an adult, an enhanced sentence. For purposes of this subsection, a juvenile adjudication shall include, but not be limited to, a delinquent child or youthful offender adjudication, a juvenile adjudication in another jurisdiction, or an adult conviction in another jurisdiction that would be a juvenile adjudication in the commonwealth.

SECTION 3. Notwithstanding any general or special law to the contrary, any person currently serving a sentence pursuant to section 10G of chapter 269, including being on probation or parole, where a juvenile adjudication, including but not be limited to, a delinquent child or youthful offender adjudication, a juvenile adjudication in another jurisdiction, or an adult conviction in another jurisdiction that would be a juvenile adjudication in the commonwealth, has been used as a prior predicate prior conviction, then such person shall be resentenced without that juvenile adjudication being used as a prior predicate conviction. If a defendant is resentenced under this section, the sentence shall not be increased in length of committed time, probation, or parole.
