Whether the necessity instruction was legally deficient because it did not expressly tell the jury to assess necessity from the perspective of a reasonable person acting on the facts as they appeared at the time.
Holding
Assuming the instruction did not adequately convey that perspective, any error was harmless because Nelson did not present facts sufficient to support a necessity defense.
Reasoning
Necessity is a justification defense, not a claim that the defendant lacked criminal intent. Its premise is public policy: violating a lesser legal interest may be justified when doing so avoids a greater harm. The usual elements are that the defendant acted to prevent a significant evil, had no adequate lawful alternative, and caused harm that was not disproportionate to the harm avoided.
The court agreed with Nelson’s basic legal premise. A defendant may invoke necessity when he reasonably, though mistakenly, believes an emergency exists and that no adequate lawful alternative is available. The comparison of harms likewise should rest on harms reasonably foreseeable when the defendant acted, rather than solely on harm later shown to have occurred.
But Nelson’s own proposed instruction did not expressly state this reasonable-belief standard either. More importantly, the evidence could not satisfy the elements of necessity under either formulation, so a more precise instruction could not have changed the verdict.
Nelson’s supposed emergency was the possibility that his truck, already stuck in mud for several hours, might tip over and damage its roof. The danger was neither immediate nor dire: after roughly twelve additional hours of unsuccessful efforts, one companion slept in the truck and it still had not tipped over.
Nelson also had lawful alternatives. People stopped on several occasions and offered physical assistance, rides, or help contacting the state troopers or a tow truck. Those alternatives defeated the claim that commandeering state equipment was necessary.
Finally, the threatened damage to Nelson’s truck was disproportionate to the unauthorized taking and risky operation of sophisticated, expensive state equipment. The no-trespassing signs, the seriousness with which the legislature treated joyriding and reckless property destruction, and the substantial potential for damage all confirmed that Nelson chose a greater harm to avert a comparatively minor one.
