That latter provision could lead to the release of a convicted murderer in San Jose.
Randy Thompson was just 15 years old at the time when he and 16-year-old Jae Williams stabbed 15-year-old Michael Russell to death at his San Jose home in 2009.
At the time of the murder, Thompson said he worshiped the devil and took a life just because he wanted to. It was called a "thrill kill."
Thompson and Williams were both tried as adults in separate trials and sentenced to 26 years to life in prison.
But with the passage of Proposition 57 in 2016, these cases could be put back into juvenile court.

The measure gives judges the authority, not prosecutors, to decide if juveniles would be tried in adult court.
Since Thompson has not exhausted his appeals, he is allowed a "transfer hearing" in juvenile court.
If a judge decides to transfer the case to juvenile court, the now 24-year-old Thompson could be released.
Russell's family has endured three trials over nine years and promises to continue going to all of Thompson's hearings.
David Ball, associate professor at the Santa Clara University School of Law, says it's unlikely Thompson will be released any time in the near future. However, he says these types of cases have to make their way through the courts on a circumstantial basis.
"The appeals are going to run their course, and from here on out, Proposition 57 has a very clear, procedural mechanism, for dealing with these cases into the future," said Ball.

"The thought of him getting out is really scary. Because for society, I wouldn't want him living next door to me. I mean he's not a safe person. He can't exist in society. He's an animal," said Cathy Russell, the aunt of Michael Russell.
Thursday was just a detention hearing, a formality on the way to an eventual transfer hearing.
Russell's family believes the other defendant, Jae Williams, will also apply for a transfer hearing.
Thompson is scheduled to be back in court on June 5.

Thompson has not exhausted all of his appeals to his conviction so he is being allowed the opportunity for a “transfer hearing” in juvenile court.— Matt Keller (@MattKellerABC7) May 3, 2018
If a judge ruled his case should be transferred to juvenile court his sentencing would then revert to the juvenile sentencing (disposition). He would be held until 23.— Matt Keller (@MattKellerABC7) May 3, 2018
