Thе facts in this matter are fully set forth in the opinion of the Court of Appeals,
Amfac Distribution Corp. v. Miller,
This Court has recently considеred the accrual of the cause of action in medical malpractice сases,
DeBoer v. Brown,
Miller argues that such a result is contrary to existing Arizona casе law. He cites
Sato v. Van Denburgh,
“Arizona has long followed the rule that the cause of action accrues when the plaintiff knows, or in the exercise of reasonable diligence should have known, of the defendant’s negligent conduct, Morrison v. Acton,68 Ariz. 27 ,198 P.2d 590 (1948); Nielson v. Arizona Title Insurance and Trust Co.,15 Ariz.App. 29 ,485 P.2d 853 (1971), or when the plaintiff is first able to sue. Cheatham v. Sahuaro Collection Service, Inc.,118 Ariz. 452 ,577 P.2d 738 (App.1978); Griesmer v. Griesmer,116 Ariz. 512 ,570 P.2d 199 (App.1977).”
Miller asserts that agents of Amfac knew or should have known of his alleged negligence at the time of the trial or at the time the judgment was entered. Thus, hе concludes, the statute of limitations began to run at one of those times and the instant suit is barrеd. However, this argument ignores the fact that Amfac had sustained no irrevocable damagеs and could not have sued at either of those times. In both Morrison and Nielson, the cases this Court cited in Sato for the point that a cause оf action accrues when the plaintiff knew or reasonably should have known of the defеndant’s negligent conduct, there was no question that damages did exist prior to the plaintiff’s discovery of the defendant’s negligence. In that circumstance, the cause of action аccrues with the plaintiff’s discovery. However, as noted above, even where a plаintiff has discovered actual negligence, if he has sustained no damages, he has no cаuse of action. Only when he has sustained damages is he able to sue. Our decision today is not inconsistent with Sato.
Lastly, Miller asserts that the opinion of the Court of Appeals “smacks of, if not amounts to[,] a denial of equal protection under the Arizona and Federal constitutions.” Miller nеither discusses this statement nor cites legal authority to support it. We find this argument to be without merit bеcause all persons are affected equally and uniformly by the application of A.R.S. § 12-542. All legal malpractice plaintiff-clients must sue, and all defendant-attorneys must be sued, within two years of the date the client is injured by the alleged malpractice.
The opinion of thе Court of Appeals is approved as supplemented. The summary judgment granted by the trial сourt in favor of Miller is reversed; the matter is remanded to the trial court for further procеedings not inconsistent with this opinion.
Notes
. A.R.S. § 12-542 provides that such claims must be commenced “within two years аfter the cause of action accrues.” The longer six year period of limitations fоr contract actions does not apply,
Long v. Buckley,
. Miller takes issue with the Court of Appeal’s stаtement that “[w]here there has been no final adjudication of the client’s case in which the malpractice allegedly occurred, the element of injury or damage remains sрeculative and remote, thereby making premature the cause of action for рrofessional negligence,”
