By Chapter 538, RSMo Supp. 1976, (§ 538.010 thru 538.080) effective January 1, 1977, the General Assembly provided for the establishment of a Professional Liability Review Board (Board) to examine, inter alia, malpractice claims against “health care providers” including hospitals as well as physicians. Before such claims could be *39filed in any court, plaintiffs were required to first travel through a detailed Board “review” process. In our decision of State ex rel. Cardinal Glennon Memorial Hospital v. Gaertner, 583 S.W.2d 107 (Mo. banc 1979), Chapter 538 was declared invalid because it imposed a procedure as a precondition to access to the courts, violative of Art. I § 14 of the Missouri Constitution. Describing the reach of the decision, the final paragraph of the supplemental opinion at page 118, stated:
“We, therefore, order that the statutes of limitations shall be tolled pursuant to § 538.020 as to those claims submitted to the Professional Liability Review Board between the effective date of Chapter 538 and February 28, 1979.”
It was our purpose to make clear by the referenced portion of the opinion that litigants whose claims arose before or during the period of the Act’s “apparent” validity, i. e., January 1, 1977, to the effective date of the declaration of invalidity, February 28, 1979, and who had submitted claims to the Board for review during that period would not be penalized by the passage of that time. That during such period, pertinent statutes of limitations were tolled as to such claims, this because such claimants were pursuing a required legislative course, presumably constitutional until otherwise declared by this Court. The cases at bar, consolidated in this appeal, require application and some exposition of the referenced portion of the “Cardinal Glennon” opinion.

Gary Johnson asserts a claim against Bedford Knipschild, M.D., alleging malpractice during treatment received November 8, 1976, about one and two-thirds months before January 1, 1977, the effective date of Chapter 538. Johnson filed his notice of claim with the Board September 28,1978, but final action on that notice had not been forthcoming prior to invalidation of that Chapter. Suit was filed in the circuit court on September 20, 1979, and defendant, realtor herein, here moved to dismiss, raising as a bar the two year statute of limitation, § 516.105, RSMo Supp. 1976. On denial of this motion, relator sought prohibition against respondent in the Court of Appeals, Western District, where the preliminary writ issued. Thereafter, the cause was transferred prior to opinion and, bearing our number 62539, is considered here as though on original appeal. The statute was tolled for the period January 1, 1977, to February 28, 1979, and ran only during the periods November 8, 1976, to January 1, 1977, and February 28, 1979, to September 20, 1979. Accordingly, the action is not barred by proffered statute of limitations and the preliminary writ previously entered is quashed.

Debbie Dawson commenced her claim against Michael A. Figura, D.P.M., charging malpractice in treatment rendered March 23, 1977, by filing notice with the Board on February 4, 1979. Here too, final Board action was not reached before invalidation of Chapter 538 and suit was filed in the circuit court September 20, 1979. Defendant, relator here, moved for summary judgment or to dismiss the action as barred by the two year limitation period of § 516.105, RSMo Supp. 1976, and on denial, sought prohibition in the Court of Appeals, Eastern District. The preliminary writ issued, only to be quashed after opinion in that court. The cause is transferred and, bearing our number 62513, is also considered as though on original appeal. Because the statute was tolled from the date the cause of action arose until February 28, 1979, the claim is not barred by the two year statute of limitations and the preliminary writ previously entered is quashed.

Raymond Ashcraft allegedly died as a result of the medical malpractice of Barnes Hospital (Barnes), Alvin S. Wenneker, M.D. and Alvin S. Wenneker, Inc., P.C., on January 27, 1978. His surviving spouse filed notice of claim with the Board on January 21, 1979. As in the cases previously discussed, prior to final action by the Board, *40this Court invalidated Chapter 538. On August 22, 1979, plaintiff, Lucille Ashcraft, brought her action as surviving spouse in the Circuit Court of the City of St. Louis, for her husband’s wrongful death alleging malpractice. Defendants moved to dismiss contending the cause was barred by the provisions of § 537.080, RSMo 1978, the statute limiting appropriation of the action by the surviving widow to one year where the decedent is survived by one or both parents. Crane v. Riehn, 568 S.W.2d 525 (Mo. banc 1978); Kausch v. Bishop, 568 S.W.2d 532 (Mo. banc 1978). Following denial of this motion, Barnes, relator here, sought prohibition in the Court of Appeals, Eastern District, to prevent respondent’s further action in the cause. After issuance of a preliminary writ, the cause, now number 62594, was transferred here on recommendation of the Court of Appeals prior to opinion. For the reasons assigned above concerning the tolling of § 516.105, the one year limitation of § 537.080 was tolled until the invalidation of Chapter 538 by this Court effective February 28, 1979. Thus, suit was filed within one year after commencement of the running of the statute, and the preliminary writ previously entered is quashed.
