California Legal Brief

The Rule of People v. Nelson is that a trial court may properly deny mental health diversion when it finds as trier of fact that the defendant's mental health disorders were not a significant factor in the commission of the charged offenses, under circumstances where the court expressly rejects expert testimony linking mental illness to criminal conduct and finds the defendant poses a public safety risk based on extensive criminal history.

The Rule of People v. Superior Court (Taylor) is that mental health diversion may not be granted when no evidence supports that the defendant will comply with treatment in the community, even where experts opine the defendant would not pose an unreasonable risk to public safety if treated, under circumstances where the defendant has a documented history of abandoning treatment facilities and refusing prescribed medication.

The Rule of Flareau is that a trial court abuses its residual discretion when denying mental health diversion based on finding that other factors were "more" motivating than the defendant's mental disorder, under circumstances where the defendant is eligible for diversion and the mental disorder was at least a contributing factor to the offense.

The Rule of Joel Praneet Siam is that when determining whether a defendant's symptoms would respond to treatment under Penal Code section 1001.36(c)(1), a trial court may not override a qualified mental health expert's opinion with its own lay opinion about treatment responsiveness, under circumstances where a licensed psychologist provides an uncontroverted expert opinion that the defendant's mental disorder symptoms would respond to treatment.
