vs.
BOARD OF CONCILIATION AND ARBITRATION.
Supreme Judicial Court of Massachusetts, Essex.
May 5, 1959.
May 29, 1959.
Present: WILKINS, C.J., SPALDING, COUNIHAN, WHITTEMORE, & CUTTER, JJ.
Dean E. Nicholson, for the petitioner.
Leo Sontag, Assistant Attorney General, (Raymond F. O'Connell with him,) for the respondent.
*302 WILKINS, C.J.
The first question is whether the appeal is timely. A demurrer to this petition for a writ of certiorari was sustained on July 21, 1958. On July 31, a motion to amend the petition was filed. This motion was denied on October 6. On October 15 the petitioner appealed from the order sustaining the demurrer and the denial of the motion to amend. On December 17 that appeal was waived. On December 22 judgment was entered for the respondents. On December 26 the petitioner appealed from the judgment. This was within the twenty days permitted by G.L.c. 213, § 1D,[1] and G.L. (Ter. Ed.) c. 214, § 19. Hence the appeal is rightly here.
The board of conciliation and arbitration in the performance and exercise of its duties is a quasi judicial tribunal. Certiorari is a proper remedy to review the lawfulness of its action in hearing a labor arbitration under G.L.c. 150, § 5 (as amended through St. 1938, c. 364, § 2). Thus a failure to decide all the material questions submitted has been held on certiorari to invalidate an award of the board.[2]Boott Mills v. Board of Conciliation & Arbitration, 311 Mass. 223. In similar proceedings an award of the board has been held invalid because a report of experts was irregularly received in evidence without affording the parties an opportunity to be heard. Burns v. Thomas Cook & Sons, Inc. 317 Mass. 398. In the case last cited, it was said that an award of the board is to be treated as would an award at common law (page 401). This means that in the absence of fraud the decision of the arbitrators is binding even though they may have committed an error of law or fact in reaching their conclusion. Phaneuf v. Corey, 190 Mass. 237, 246-247. J.F. Fitzgerald Constr. Co. v. Southbridge Water Supply Co. 304 Mass. 130, 134, and cases cited. Baldwin v. Moses, 319 Mass. 401, 402. While it is error of law, and not merely error of fact, to make a finding which is not warranted by *303 the evidence (A.B. & C. Motor Transp. Co. Inc. v. Department of Pub. Util. 329 Mass. 719, 722), this is not an error which will invalidate the decision of arbitrators, or will lead to quashing the proceedings on certiorari.
In the case at bar the allegations of the petition do not state a case for granting the writ. The petition alleges that the award "wrongly concluded as a matter of law on the evidence introduced at the hearing that the petitioner's employees were entitled to their full vacation pay and holiday pay for May 30, 1957, and your petitioner is aggrieved by incorrect conclusions of law ... and by the erroneous award made ... on the evidence introduced at the hearing." These allegations do no more than to assert that there are unspecified errors of law as well as the error of making an erroneous finding on the evidence.
Judgment affirmed.
