TPC §9.22 wrote:NECESSITY. Conduct is justified if:
(1) the actor reasonably believes the conduct is immediately necessary to avoid imminent harm;
(2) the desirability and urgency of avoiding the harm clearly outweigh, according to ordinary standards of reasonableness, the harm sought to be prevented by the law proscribing the conduct; and
(3) a legislative purpose to exclude the justification claimed for the conduct does not otherwise plainly appear.
