California Legal Brief

The Rule of People v. Dunn is that a trial court must give CALCRIM No. 224 sua sponte when the prosecution substantially relies on circumstantial evidence to prove guilt, under circumstances where the prosecution's case depends primarily on inferences rather than direct evidence of the defendant's possession or control.

Appeal from judgment after jury trial in Humboldt County Superior Court.

Defendant Appellant was Morgan James Dunn — the felon found guilty of unlawful firearm and ammunition possession based on weapons found in a cabin.

Plaintiff Respondent was The People — the prosecution seeking conviction for multiple firearm and ammunition possession charges.

The suit sounded in criminal law violations of unlawful firearm and ammunition possession under Penal Code sections 29800(a)(1) and 30305(a)(1).

The key substantive facts leading to the suit were that in 2022, sheriff's deputies searched a cabin at Hideaway Hills where Dunn allegedly lived as caretaker, finding four loaded firearms and ammunition in a bedroom closet along with Dunn's personal documents, wallet, and other belongings, despite Dunn's felony conviction prohibiting firearm possession.

The procedural result leading to the Appeal: The trial court convicted Dunn on all nine counts after jury trial, ruling that the circumstantial evidence sufficiently established Dunn's possession and control of the firearms and ammunition found in the cabin.

The key question(s) on Appeal: 1. Whether the trial court erred by failing to give CALCRIM No. 224 sua sponte regarding evaluation of circumstantial evidence. 2. Whether the trial court erred by giving a unanimity instruction on firearm counts when each count charged possession of only one specific firearm.

The Appellate Court held that while the trial court erred on both instructional issues, the errors were harmless because the circumstantial evidence strongly supported the verdicts and the jury received separate verdict forms for each firearm count with instructions to consider each count separately.

The case is inapplicable when the prosecution's case relies substantially on direct evidence of possession rather than circumstantial evidence, or when instructional errors actually confuse the jury about the specific elements they must find for each separate count.

The case leaves open whether CALCRIM No. 224 must be given in cases where circumstantial evidence is strong but not the primary basis for conviction, and the precise standard for determining when circumstantial evidence is "substantially relied upon" by the prosecution.
