The failure of a plaintiff to allege facts sufficient to maintain a claim.
In reviewing the dismissal of this petition for failure to state a claim, courts grant the petition its broadest intendment and liberally construe its averments. Paddock Forest Residents Ass'n v. Ladue Service Corp., 613 S.W.2d 474, 476 (Mo.App. 1981). They accept as true all factual allegations and their favorable inferences. Nelson v. Wheeler Enterprises, Inc., 593 S.W.2d 646, 647 (Mo.App. 1980). If the averments thus viewed invoke principles of substantive law upon which relief can be granted to plaintiff, the petition is not subject to dismissal. Paddock Forest Residents Ass'n, 613 S.W.2d at 476. Any reasonable doubt with regard to the petition's sufficiency is resolved in favor of plaintiff. Nelson, 593 S.W.2d at 647.
