Arizona Medical Malpractice Laws

Arizona has no caps on medical malpractice damages — the Arizona Supreme Court struck down damage caps as unconstitutional in Eastin v. Broomfield (1987), holding they violate the right to jury trial and the anti-abrogation clause. This makes Arizona one of the most plaintiff-friendly states for med mal damages. The statute of limitations is 2 years with no general statute of repose. A preliminary expert opinion affidavit must be served with initial disclosures.
