Integrated Health Services, Inc. and Gra-vois Health Care Center, Inc., (“Appellants”) appeal from the trial court's order dismissing their Petition for Certiorari, Declaratory Judgment, Injunction and Administrative Review, which sought judicial review of a decision by the Missouri Health Facilities Review Committee. The petition alleged Respondent Missouri Health Facilities Review Committee (“Review Committee”) denied Appellants their rights under § 197.300, et. seq., RSMo.1986 and pertinent sections of the Missouri Certificate of Need Law as amended, RSMo.Supp.1990, when reviewing Respondent Vencor, Inc.’s (“Vencor”) application for a Certificate of Need. Judgment affirmed.
In reviewing the trial court’s dismissal of a petition based solely on the pleadings, this court must determine if the averments of the petition entitle plaintiff to relief as a matter of law, when accepting all facts alleged as true and construing all allegations in favor of the plaintiff. Lowrey v. Horvath, 689 S.W.2d 625, 626 (Mo. banc 1985); Martee v. City of Kennett, 784 S.W.2d 621, 622-23 (Mo.App.1990).
Vencor made application to the Review Committee for a Certificate of Need for a health care facility that provides long term care for ventilator patients. Such application is required before a new health service institution may be developed. The purpose of the Certificate of Need is to reduce unnecessary duplication of health care facilities and to reduce the cost of health care. Comm. Care Ctrs. v. Health Fac. Rev. Com., 735 S.W.2d 13, 14 (Mo.App.1987).
Appellants provide, among other services, long term care for ventilator dependent patients. Although noting that the petition does not allege any facts establishing that Appellants are within the relevant “health service area”, the Review Committee and Vencor acquiesce that Appellants are “affected persons” with respect to Vencor’s application for a Certificate of Need as defined in § 197.305(1) RSMo.1986. Appellants were notified of the date, time and location of an August 29, 1990, meeting of the Review Committee at which Vencor’s application for a Certificate of Need was reviewed. At the August 29, 1990 meeting, Appellants appeared and made a presentation in opposition to Vencor’s application. The Review Committee then denied the application because of a 4-4 tie vote.
Thereafter, the representatives of Appellants and Vencor were dismissed by the Review Committee. After finishing other Review Committee business, the Review Committee voted to reconsider Vencor’s application, at which time the Review Committee voted in favor of a motion to approve Vencor’s application.
In their Petition, Appellants argue that the actions of the Review Committee in taking the second vote on August 29, 1990 denied them their right to notice, right to request a hearing, right to be heard and right to receive the Review Committee’s written findings and conclusions, which is in contravention of § 197.330.1(2), (3), (6), RSMo.Supp.1990.1
*679Appellant’s Petition was filed in the circuit court on September 28, 1990. Vencor filed a motion to dismiss all counts of the petition contending that Appellants lacked standing to proceed with the action because Appellants are not an aggrieved party pursuant to § 536.100, RSMo.1986.2 The Review Committee also filed a motion to dismiss, asserting that the circuit court lacked subject matter jurisdiction. The circuit court granted both motions and this timely appeal followed.
Section 197.335 RSMo.Supp.1990 limits judicial review of the Review Committee’s actions to an appeal by an unsuccessful applicant, first to the Administrative Hearing Commission, and then to the circuit court. See Mo. Health Fac. v. Administrative Hearing Comm’n, 700 S.W.2d 445, 449 (Mo. banc 1985) (Review Committee as well as the unsuccessful applicant may seek judicial review of the Administrative Hearing Commission’s decision.). The appellate courts have consistently held that competitor “affected persons” do not possess standing to seek judicial review of the Review Committee’s decision to approve or disallow a Certificate of Need. Health Serv. Mgt. v. Health Fac. Review, 791 S.W.2d 732, 735 (Mo.App.1990); West Cty. Care Ctr. v. Review Committee, 773 S.W.2d 474, 476 (Mo.App.1989).
“Affected persons” have an interest in a Review Committee decision only during the information gathering phase of the proceedings. Health Serv. Mgt., 791 S.W.2d at 735; West Cty. Care Ctr., 773 S.W.2d at 475-76; Mo. Health Care v. Health Fac. Rev. Com., 777 S.W.2d 241, 243 (Mo.App.1989) (Association of competitors lacked standing to seek judicial review of exemption from Certificate of Need requirement.). Specifically, an “affected person” must be given notice of a review for a Certificate of Need by a proposed new facility in the service area, § 197.330.1(2), RSMo.Supp.1990; the right to present their views at a public hearing, § 197.330.1(3), RSMo.Supp.1990; and the right to receive the decision entered upon the application if a prior written request has been made, § 197.330.1(6), RSMo.Supp.1990.
Here, Appellants do not claim there was a lack of notice of the application for a Certificate of Need, nor that they were denied the opportunity to present their views on August 29, 1990. Rather, appellants claim, that since there was a second vote on the occasion reversing the Review Committee’s initial decision, they should be *680entitled to either reinstatement of the initial decision of the Review Committee or a remand of the matter back to the Review Committee with an order requiring it to give Appellants notice plus the right to be heard again. Appellants have already availed themselves as “affected persons” to any and all interest they have in these proceedings; that is, full participation in the information gathering phase of the Certificate of Need application process. Neither the applicable statutory provisions nor the decisions interpreting them indicate that an “affected person” has any standing to seek judicial review of alleged procedural irregularities in the decision making phase of the proceedings. Further, the petition does not allege that Appellants, pursuant to § 197.330.1(6), RSMo.Supp. 1990, filed prior requests in writing to be informed of the decision of the Review Committee and therefore, they cannot now be heard to complain.
Appellants were given every opportunity afforded to them by statute to participate in the information gathering phase of the Certificate of Need application proceeding. Appellants have no standing to seek judicial review in regards to the manner in which the Review Committee acts upon the application once the information gathering phase of the proceeding is closed.
The judgment is affirmed.
All concur.
