    Allstate Insurance Company, Appellant, v. Rule et al., Appellees.
    (No. 80-160
    Decided December 10, 1980.)
    
      
      Dooley, Heath & Schneider Co., L.P.A., and Mr. James V. Heath, for appellant.
    
      Messrs. Musgrave, Musgrave & Casey, Mr. Raymond G. Musgrave, Mr. James M. Casey and Mr. Joseph L. Cain, for appellee Judy Branham.
   Per Curiam.

Three fundamental errors, arising from the informal hearing conducted by the trial court on the merits of Allstate’s claim, dictate that the judgment entered against Allstate on its complaint for a declaratory judgment be set aside and the cause remanded for further proceedings. Therefore, it is unnecessary for this court to consider the claim that the trial court abused its discretion in refusing to grant Allstate’s request for a continuance due to the inclement weather conditions.

First, the provisions of Civ. R. 41(B)(1) provide for a dismissal upon the failure of the plaintiff to prosecute a claim, and such a dismissal operates as an adjudication on the merits. Civ. R. 41(B)(3). Hence, where a plaintiff fails to appear on the date set for a hearing, the court may either order a Civ. R. 41(B)(1) dismissal or grant a continuance. There is no authority in the Civil Rules for proceeding to a trial on the merits of the plaintiff’s claim in his absence.

Secondly, Section 7 of Article I of the Constitution of Ohio requires an oath or affirmation as a prerequisite to the testimony of a witness. See Clinton v. State (1877), 33 Ohio St. 27, paragraph two of the syllabus; State v. Ballou (1969), 21 Ohio App. 2d 59, 60. Here, the trial court relied erroneously upon the unsworn testimony of Rose Weser and Stanley Weser in reaching its decision.

Thirdly, Civ. R. 33(A) mandates that answers to interrogatories be signed, sworn to and served upon the party submitting them. A document which purports to contain the answers of the defendant Rule to interrogatories submitted by the defendant and cross-claimant Branham was filed with the clerk of courts and apparently considered by the court with respect to Allstate’s claim, notwithstanding the fact that the document did not contain the signature of Rule, bore no jurat and was not served. The use of such a document in determining the merits of a claim is erroneous.

For the foregoing reasons, the judgment of the Court of Appeals is reversed and the cause remanded to the trial court for further proceedings.

Judgment reversed.
