3453.Extension of Commitment (Pen. Code, § 1026.5(b)(1))
<insert name of respondent> has been committed to a
mental health facility. You must decide whether (he/she) currently poses
a substantial danger of physical harm to others as a result of a mental
disease, defect, or disorder. That is the only purpose of this proceeding.
You are not being asked to decide <insert name of
respondent>’s mental condition at any other time or whether (he/she) is
guilty of any crime.
To prove that <insert name of respondent> currently poses a
substantial danger of physical harm to others as a result of a mental
disease, defect, or disorder, the People must prove beyond a reasonable

Proof by a preponderance of the evidence is a different burden of proof

not that the fact is true.]

The court has a sua sponte duty to instruct on the standard for extending
commitment, including the constitutional requirement that the person be found to
have a disorder that seriously impairs the ability to control his or her dangerous
behavior. (People v. Sudar (2007) 158 Cal.App.4th 655, 663 [70 Cal.Rptr.3d 190].).
Give CALCRIM No. 219, Reasonable Doubt in Civil Commitment Proceedings and
CALCRIM No. 3550, Pre-Deliberation Instructions, as well as any other relevant
post-trial instructions, such as CALCRIM No. 222, Evidence, or CALCRIM No.
The constitutional requirement for an involuntary civil commitment is that the
person be found to have a disorder that seriously impairs the ability to control his or
her dangerous behavior. (Kansas v. Crane (2002) 534 U.S. 407, 412-413 [122 S.Ct.
867, 151 L.Ed.2d 856]; In re Howard N. (2005) 35 Cal.4th 117, 128 [24 Cal.Rptr.3d
866, 106 P.3d 305].) This requirement applies to an extension of a commitment after
a finding of not guilty by reason of insanity. (People v. Zapisek (2007) 147
Cal.App.4th 1151, 1159-1165 [54 Cal.Rptr.3d 873]; People v. Bowers (2006) 145
Cal.App.4th 870, 878 [52 Cal.Rptr.3d 74]; People v. Galindo (2006) 142
Cal.App.4th 531 [48 Cal.Rptr.3d 241].)
• Instructional Requirements. Pen. Code, § 1026.5(b)(1).
• Unanimous Verdict, Burden of Proof. Conservatorship of Roulet (1979) 23
Cal.3d 219, 235 [152 Cal.Rptr. 425, 590 P.2d 1] [discussing conservatorship
proceedings under the Lanterman-Petris-Short Act and civil commitment
proceedings in general].
• Affirmative Defense of Medication. People v. Bolden (1990) 217 Cal.App.3d
1591, 1600-1602 [266 Cal.Rptr. 724].
• Serious Difficulty Controlling Behavior. People v. Sudar (2007) 158
Cal.App.4th 655, 662-663 [70 Cal.Rptr.3d 190] [applying the principles of
Kansas v. Crane and In re Howard N.].
Extension of Commitment
The test for extending a person’s commitment is not the same as the test for
insanity. (People v. Superior Court (Williams) (1991) 233 Cal.App.3d 477, 490 [284
Cal.Rptr. 601].) The test for insanity is whether the accused “was incapable of
knowing or understanding the nature and quality of his or her act or of
distinguishing right from wrong at the time of the commission of the offense.” (Pen.
Code, § 25(b); People v. Skinner (1985) 39 Cal.3d 765 [217 Cal.Rptr. 685, 704 P.2d
752.) In contrast, the standard for recommitment under Penal Code section
1026.5(b) is whether a defendant, “by reason of a mental disease, defect, or disorder
[,] represents a substantial danger of physical harm to others.” (People v. Superior
