delivered the Opinion of the Court.
This is an appeal from an order of the district court of the fourth judicial district, in and for the County of Missoula, reversing an order of the Workmen’s Compensation Division which had awarded compensаtion to claimant Clara Bag-ley from her employer Hotel Florence company.
On June 27, 1968, Clara Bagley (hereinafter referred to as claimant) fell while working in the basement of the Flоrence Hotel Motor Inn. Shortly thereafter, claimant went to the office and reported to Dorothy Adamson, a secretary of the Hotel, that she had fallen. As an employee of the hotel, Mrs. Adam-son was the person who had the responsibility for filing of workmen’s compensation claims. Since the conversations which took place between claimant and Mrs. Adamson are crucial to a proper determination of this matter, and particularly the issue ■of equitable estoppel, they are set forth in some detail. The *147 transcript of the proсeedings before the hearings examiner for the Workmen’s Compensation Division shows the fellowing:
“Q. After you told her you had fallen, did you tell her whether or not you were going to consult with a doctor for any injury you received? A. No.
“Q. Did you in any way indicate to her you had been injured as a result of the fall? A. No, I said I was shook up, but that’s all.
“Q. You said nothing to alert her to the fact you were going to require medical attention as a result of this fall at that particular time? A. No.
“ * * ®
“Q. Did Mrs. Anderson in any way that you can recall attempt to dissuade you or prevent you from filing a claim for compensation? A. No. she thanked me for reporting it # * * > >
The testimony of Mrs. Adamson during cross-examination by Mr. Sheridan was in accord:
“Q. On June 27, 1968, which was the day Mrs. Bagley fell at the hotel, you had a conversation with her, did you not. A. Yes.
‘ ‘ Q. She advised you she had slipped and fallen in the basement? A. Yes.
“Q. Did you inquire of her at that time as to whether or not she had been injured, or whether or not she was going to seek medical attеntion? A. I asked her if she was hurt and she said she was not hurt, just shook up.
‘ ‘ Q. Did she advise you whether she was going to seek medical attention at that time? A. I don’t think so.
“Q. Were you aware that she sought medical attention at that time? A. No.”
Claimant admitted on direct examination that she did not seek medical help at that time.
In February 1969, claimant experienced difficulties with her back. She consulted with Dr. W. B. Swartz of Missoula and *148 was hospitalized from February 11 to February 14, 1969. Even though claimant went to see Dr. Swartz abut her back in February 1969, she never advised Mrs. Adamson of this fact. When she was hospitalized by Dr. Swartz she advised Mrs. Adamson she was off work because of hospitalization without relating it in any way to the fall. Claimant continued to work for the Florence Hotel until December, 1970.
Claimant did not talk to Mrs. Adamson about the fаll again until May, 1971, when Mrs. Adamson and the hotel were notified that claimant was alleging injury as a result of the fall on June 27, 1968. Claimant filed a claim with the Workmen’s Compensation Division on September 27, 1971.
Despite the foregoing testimony, the hearings examiner for the Workmen’s Compensation Division made the following finding of fact:
“6. That the claimant did report this incident to Mrs. Dorothy M. Adamson in person on the datе of the accident but Mrs. Adamson failed to fill out a form 37, Employer’s First Report of Injury or to inform the claimant that she must file a claim form 54 within a year from that date. This constitutes the type of equitablе estoppel contemplated by the cases to breach the ■defense of failure to file a claim within a year under 92-601.”
It was this finding of conduct amounting to an equitable ■estoppel which was subsequently reversed by the district court. In accordance with the district court reversal, the administrator of the Workmen’s Compensation Division issued an order dated July 20, 1973, denying compensatiоn benefits to claimant.
On appeal to the district court, it was stipulated “That the issue is whether the record supports the findings of the Industrial Accident Board of an equitable estoppel, inasmuch as the Claimant did not file the claim for the benefits within one (1) years.” We hold, as the district court did, that the record does not support a finding of equitable estoppel and that claimant’s сlaim is barred for failure to file it within one year as required by section 92-601, R.C.M. 1947.
*149
The findings of fact submitted by the hearings officer for the Workmen’s Compensation Division determined that the hotel was estoppеd to assert section 92-601, R.C.M. 1947, as a bar to the claim because of the conduct of Mrs. Adamson. It is of critical importance in this case to note that Mrs, Adamson did not know on the date of the аccident, or at any time during the next three years, that claimant was alleging any injury as a result of her fall. On the contrary, claimant advised her that she was not injured and would not be seeking medical attention. In light of these facts it is inconceivable that Mrs. Adamson, as a representative of the employer, should be required to solicit a claim for compensation from the claimаnt. Ricks v. Teslow Consolidated,
The leading case in Montana on the issue of equitable estoppel in compensation claims is Lindblom v. Employers’ etc., Assur. Corp.,
“Generally speaking, the following are the essential elements which must enter into and form a part of an equitable estoppel in all of its applications: ‘1. There must be conduct — acts, language, or silence — amounting to a representation or a concealment of material facts. 2. These facts must be known to the party estopped at the time of his said conduct, or at least the circumstances must be such that knowledge of them is necessarily imputed to him. * * ’ ”
The alleged conduct constituting the estoppel was that Mrs. Adamson failed to fill out a form 37, Employer’s First Report оf Injury or to inform the claimant that she must file a claim form 54 within a year from that date. It must be remembtred that there was no indication given to Mrs. Adamson or the Florence Hotel that claimant had suffered any injury. The “material fact” in this case was that claimant, not some hypothetical injured person, had to file a claim. Although Mrs. Adamson and the Hotel Company knew, in the abstract, that forms 37 and 54 had tо be filed in the event *150 of an injury, that fact could not become a “material fact”, subject to misrepresentation or concealment, until the Hotel Company or Mrs. Adamson had noticе that claimant had in fact suffered an injury.
In order to estop the employer from claiming the benefit of section 92-601, R.C.M.1947, there must be evidence that the employer or his agent had done something either to lead the employee reasonably to believe he need not file a claim or has engaged in conduct which discouraged or prevented the employee frоm filing a claim within the statutory time limit. Levo v. Gen.-Shea-Morrison,
Counsel for claimant also attempts to argue that the injuriеs to claimant were latent in nature and justify the failure to file a written claim for more than three years following the accident. However, this issue was never raised at the hearing before thе Workmen’s Compensation Division and was not ruled upon by either the Workmen’s Compensation Division or the district court. The “latent injury” theory as an exception to the one year time limit for filing of сlaims is only now brought before this Court following the district court reversal of a finding of equitable estoppel. This Court has stated before in Spencer v. Robertson,
«* # * Upon appeal, this Court will consider for review only those questions raised in the trial court.”
Claimant attempts to argue that the “latent injury” issue was raised at the hearing before the Workmen’s Compensation' *151 Division when claimant’s counsel stated: “* * * Our testimony will go to the invocation of the doctrine of estoppel.” Claimant argues “Latent injury is another form of estoppel or equitable estoppel” and “* * * by its very nature, a finding of a latent injury acts as an estoppel against the employer.”
Whether or not claimant had аny latent injury is entirely irrelevant to a finding of estoppel. An estoppel arises when a party by his acts, conduct, or acquiescence has caused another in good faith to chаnge his position for the worse. Mundt v. Mallon,
Neither did the hearings examiner’s ■ finding of fact No. 5 establish any latent injury.
Accordingly, finding no error, the decision of the district court is affirmed.
