intendent of main drainage of that department, occupied by Bliss W. Robinson, each of whom was entitled to such protection as the civil service laws of the Commonwealth afforded.
Thereupon Durkee, Mclnnes and Robinson, acting under St. 1911, c. 624, § 1, as amended by St. 1915, c. 251, petitioned the Municipal Court of Dorchester District, being a “police, district or municipal court within the judicial district” where they resided, asking that the action of the commissioner be reviewed. Due notice was given and after hearing the witnesses and arguments of counsel, the respondent court reviewed the action of the commissioner and decided in each case that the order be reversed and the petitioner reinstated in his office. The commissioner then brought these petitions asking that a writ of certiorari issue quashing the order of reinstatement, that the judgment be reversed and the petitions dismissed. To the refusal of the single justice to rule that as matter of law a writ should issue, the commissioner, who is the petitioner for this writ, excepted.
It is contended by the respondents that a writ of certiorari will not lie to review the decision of a judge of the police, district or municipal court in a case arising under St. 1915, c. 251, in the ab.sence of fraud or jurisdictional defect, this statute providing that “The decision of the justice of said police, district or municipal court shall be final and conclusive upon the parties.”
The fact that the decision of the judge is final and conclusive does not deprive the parties of the right to have errors of law corrected by writ of certiorari. In Swan v. Justices of the Superior Court, 222 Mass. 542, it was decided that, notwithstanding the language of the statute then under consideration, “there shall be no appeal from his [the Superior Court judge’s] decision,” certiorari would lie to correct material errors of law, and it was there stated that “the word 'appeal’ is used in a broad general sense, so as to cover all the ordinary proceedings for a revision by this court” p. 544. By declaring that the decision of the judge of the police, district or municipal court should be final and conclusive, the Legislature meant, in effect the same, as it did when it declared that the decision of a judge of the Superior Court should not be appealed from, for, where there is no appeal, ordinarily the finding stands and is final and
