Ariz. high court declines to narrow evidence rule

Posted: Updated:

PHOENIX -- The Arizona Supreme Court is refusing to narrow an evidence rule relating to safety improvements and other changes made after accidents.

A decision issued Thursday concerns a rule that generally doesn't allow a party in a lawsuit to use as evidence any changes that would have made an accident or other event less likely to occur.

The rule is intended to encourage defendants to not worry that changes they make would be used against them in court.

The Supreme Court said the rule applies even in cases in which post-accident changes were made for reasons unrelated to an accident or without knowledge of it.

The court ruled in a case stemming from a fatal automobile collision involving a truck that had pulled onto a highway. The state later posted warning signs.
