However, the doctrine is limited to cases in which the issue in controversy has been raised and decided in a prior appeal. Boillot v. Conyer, 861 S.W.2d 152, 154 (Mo. App. 1993); Davis v. J.C. Nichols Co., 761 S.W.2d 735, 741 (Mo. App. 1988). The mere denial of a petition for writ of prohibition where the appellate court issues no opinion is not a conclusive decision on the merits of the issue presented.
Dep't of Natural Res.Parks Recreation v. Lossos , 960 S.W.2d 537, 542 (Mo.App.S.D. 1998) (citing Laclede Gas Co. v. Labor Indus. Relations Comm'n , 657 S.W.2d 644, 649 (Mo.App.E.D. 1983)). Appellate review of questions of law is de novo. Baris v. Layton , 43 S.W.3d 390, 397 (Mo.App.E.D. 2001) (citing Boillot v. Conyer , 861 S.W.2d 152, 155 (Mo.App. 1993)). A reviewing court gives no deference to the trial court's judgment "where resolution of the controversy involves a question of law."
A decision by this court is the law of the case on all points raised and decided and the decision continues to govern throughout all subsequent proceedings both in the trial and appellate courts. Boillot v. Conyer, 861 S.W.2d 152, 154 (Mo.App.E.D. 1993). No issue decided in the first appeal will be readdressed on the second.
