This is an appeal from an order of the Workmen’s Compensation Board disallowing compensation to claimant widow. The chronology of the case is quite lengthy. The record shows that on November 8,1950, Frank Shrum, claimant’s deceased husband, filed a claim petition with the workmen’s compensation authorities on the ground *208that he was suffering from silicosis. A hearing was held June 1, 1951, and on June 4, 1951, an order was filed by the referee allowing compensation. From this award, an appeal was taken to the Workmen’s Compensation Board, which, on November 16, 1951, referred the claim to the medical board. The records being returned from the medical board on December 27,1951, without any decision as to cause of disability, the board, on April 8, 1952, remanded the record to the referee for the appointment of an impartial medical expert.
A hearing was held on May 28, 1952, and an order of disallowance was filed on December 15, 1952, from which an appeal was taken by claimant, plaintiff’s deceased husband, on December 19, 1952.
This appeal was heard by the board, and on July 29, 1953, the order of disallowance was affirmed. No further action was taken by Frank Shrum, claimant’s deceased husband. On September 9, 1953, original claimant, Frank Shrum, died, and on October 27,1953, his widow, Marion E. Shrum, claimant herein, filed a claim petition alleging silicosis contracted while in the employ of defendant as the cause of death.
A hearing before the referee was again held on December 15, 1953, at this time, however, on the petition of the widow, present claimant, and on January 7, 1954, an order disallowing an award was filed by the referee. On January 21,1954, an appeal was taken by claimant widow to the Workmen’s Compensation Board and a hearing was held before that board on February 10, 1954, at which time the order of dis-allowance by the referee was affirmed. On May 13, 1954, claimant widow appealed to this court, which appeal we now have under consideration.
It is contended by widow claimant in this case that her husband’s claim for disability was disallowed by the referee and by the board on a mistake of fact. *209She contends that as a result of an autopsy performed, she can definitely establish that her husband died as a result of silicosis, a compensable disease. It is contended by defendant in this case that, the husband not having pursued his claim, the widow is barred from action because of the statute of limitations. With this contention we cannot agree. •
“The limiting section of the act (Section 315) provides for the institution of the proceeding by the one injured within a year, and, by a separate clause, for a presentation of claims by dependents within a like period after death. Appellant contends that since Smith presented no petition for an award during his lifetime, which continued for more than one year after the accident, any cause of action on his part would have been barred had he survived and made claim, so also the right of the dependents to recover is precluded by the lapse of time, the widow not having proceeded until March 8, 1924, whereas the injury was inflicted on December 9, 1921, resulting in death on October 30, 1923. There are not, however, any words used in the act which justify the construction contended for”: Smith v. Primrose Tapestry Co., 285 Pa. 145, 150.
“They merely indicate the separate and independent character of the right of action of a widow for compensation so that nothing that her employee husband does with respect to his own right can affect her right . . . and the statutory limitation upon the assertion of her claim cannot be affected by neglect or refusal of the husband to pursue his claim”: Polk v. Western Bedding Co. et al., 145 Pa. Superior Ct. 142, 148.
We are of the opinion that decedent’s claim petition having been disallowed on a mistake of fact should not bind the widow in her claim, which is a separate and distinct claim from that of the husband’s and that an adjudication made upon a mistake ought not to be perpetuated.
*210“The rights arise under different provisions of the statute. They involve two separate and distinct parties and actions. Each action has its own subject matter and is to be treated as a separate action between different parties. The adjudication in the proceeding for disability was, when unappealed from within the time prescribed by statute, conclusive upon the employer in that action, but that is'the extent to which estoppel is effective. When a new matter was the subject to be determined and new parties were involved certainly an error of law should not be perpetuated. It clearly appearing that the original determination of liability for compensation was founded on a mistake of law, the judgment must be affirmed”: Jankaitis v. Harleigh Brookwood Coal Co., 134 Pa. Superior Ct. 125, 131. See also Lambing v. Consolidation Coal Company, 161 Pa. Superior Ct. 346.
Our attention has also been called to an identical case, Paul, etc., v. Johnstown Coal & Coke Company, et al., 74 D. &. C. 577, in a well-reasoned opinion written by McCann, P. J., in which it was held that:
“While the rights of an employe to disability payments and those of a widow to death benefits under the provisions of the Occupational Disease Act of June 21, 1939, P. L. 566, arise out of the same accident, they are separate and distinct causes of action, and an adverse decision against the employe is not therefore res adjudicata upon the widow’s claim.”
Decree
And now, to wit, February 28, 1955, after due and careful consideration, the opinion and the decree of the Workmen’s Compensation Board filed February 10, 1954, disallowing the claim petition of Marion E. Shrum, widow of Frank Shrum, be, and the same hereby is, reversed. The claim petition is returned to the Workmen’s Compensation Board and said board *211is hereby directed to conduct a hearing to establish the facts of the case.
February 28, 1955.
