In Arizona, the Arizona Constitution has an “anti-abrogation” clause (Art. 18, Sec 6) that might be kept in mind during discussions of limitations on liability:
Recovery of damages for injuries
The right of action to recover damages for injuries shall never be abrogated, and the amount recovered shall not be subject to any statutory limitation, except that a crime victim is not subject to a claim for damages by a person who is harmed while the person is attempting to engage in, engaging in or fleeing after having engaged in or attempted to engage in conduct that is classified as a felony offense.
