Split California Supreme Court ruling on parole consideration

As detailed in this Los Angeles Times article, the "California Supreme Court made it easier today for prison inmates to win parole over a governor's objections. In a 4-3 vote, the state high court said the brutality of a convict's crime may not be enough to justify a determination that a prisoner would be a danger to the public."  The full ruling is available at this link, and here is a key paragraph from the majority's analysis (emphasis in original):

In sum, the Board or the Governor may base a denial-of-parole decision upon the circumstances of the offense, or upon other immutable facts such as an inmate’s criminal history, but some evidence will support such reliance only if those facts support the ultimate conclusion that an inmate continues to pose an unreasonable risk to public safety. (Regs., § 2281, subd. (a).) Accordingly, the relevant inquiry for a reviewing court is not merely whether an inmate’s crime was especially callous, or shockingly vicious or lethal, but whether the identified facts are probative to the central issue of current dangerousness when considered in light of the full record before the Board or the Governor.
