The Court of Appeal concluded that the defendant’s habeas order, which reduced his 51-year aggregate sentence to 45 years and 8 months, but contained an unlawful sentence, was not void because (1) the defendant was entitled to petition the superior court for a writ of habeas corpus without first obtaining a certificate of probable cause; (2) the superior court could change an unlawful sentence at any time and (3) the court could reconsider the sentence upon notice from the CDCR of its possible illegality.
