A consent judgment is where all parties to a lawsuit agree to a judgment that the Court signs and executes. It is not a determination of rights. It is, instead, a recital of an agreement, and thus not ordinarily appealable. Rosemann v. Roto-Die Co., Inc., 947 S.W.2d 507, 510 (Mo. Ct. App. 1997).
The only basis to attack a consent judgment, on appeal or otherwise, is by arguing that the court lacked subject matter jurisdiction. “Subject matter jurisdiction refers to a court’s authority to render judgment in a particular category of cases.” J.C.W. ex rel. Webb v. Wyciskalla, 275 S.W.3d 249, 253 (Mo. 2009).
