California Criminal Jury Instructions (CALCRIM 2017)
CA 3475. Right to Eject Trespasser From Real Property
The (owner/lawful occupant) of a (home/property) may request that a trespasser leave the (home/property). If the trespasser does not leave within a reasonable time and it would appear to a reasonable person that the trespasser poses a threat to (the (home/property)/ [or] the (owner/ [or] occupants), the (owner/ lawful occupant) may use reasonable force to make the trespasser leave.
Reasonable force means the amount of force that a reasonable person in the same situation would believe is necessary to make the trespasser leave.
[If the trespasser resists, the (owner/lawful occupant) may increase the amount of force he or she uses in proportion to the force used by the trespasser and the threat the trespasser poses to the property.]
When deciding whether the defendant used reasonable force, consider all the circumstances as they were known to and appeared to the defendant and consider what a reasonable person in a similar situation with similar knowledge would have believed. If the defendant’s beliefs were reasonable, the danger does not need to have actually existed.
The People have the burden of proving beyond a reasonable doubt that the defendant used more force than was reasonable. If the People have not met this burden, you must find the defendant not guilty of <insert crime>.
