Pauline Cosper, Petitioner v. the Honorable John Christian Rea, Judge of the Superior Court of the State Of…

Summary

The Arizona Supreme Court held that a party appealing a mandatory arbitration award must file its witness and exhibit list with the appeal and may supplement that list only upon a showing of good cause and court permission. The court rejected the view that the eighty-day discovery period creates an automatic right to disclose additional witnesses and exhibits, vacated the appellate decision, and affirmed the order striking Cosper's supplemental disclosures.
