The bill aims to modify how juveniles who are tried as adults (extended jurisdiction juveniles) are handled in Minnesota. Key points include:

1. Juveniles 19 years and older can be subject to adult punishments and held in adult facilities without the requirement to be separated from adults by sight and sound, which is typically required for younger individuals.

2. If these juveniles require mental health or substance abuse treatment, they can be placed in facilities primarily serving adults.

3. For violations of conditions or new offenses, the court can revoke their suspended adult sentences without notice, and conduct a hearing where the offender may refute the allegations. If found guilty, adult sentences apply directly.

4. In cases of specific serious allegations, the court can extend the judgement period beyond 180 days (the maximum limit), but with judicial and prosecutorial discretion necessary for further extensions.

5. The bill also allows for these offenders who may need sex offender treatment to have continuances extended up to 24 months to facilitate treatment, again, contingent on prosecutorial consent and judicial review.

Overall, the bill broadens the authority to treat certain juveniles as adults based on age and the nature of their offenses, and allows more flexibility in handling their cases through the adult judicial and correctional systems.
