Rugg, C. J.
This is a petition for a writ of mandamus. At the hearing before the single justice, the petition was dismissed. From this decree the petitioner has appealed. The statute does not allow an appeal from a decision of a justice of this court in. a proceeding at law, that procedure being confined to decisions of the Superior Court. R. L. c. 173, § 96 as amended by St. 1906, c. 342, § 2, and St. 1910, c. 555, § 4. Cowley v. Train, 124 Mass. 226. Attorney General v. Oliver, 175 Mass. 163. Brockton v. County Commissioners, 183 Mass. 42. Norton v. Lilley, 210 Mass. 214, 218. The only way to bring before the full court for review any decision of a single justice of this court in an action at law is by exceptions, unless he reports the questions raised.
If the matter be treated as properly before us, no error of law appears upon the face of the papers. The function of a writ of mandamus directed to a lower court is to compel it to exercise its judicial functions, not to direct what action shall be taken. Crocker v. Justices of the Superior Court, 208 Mass. 162. The *79averments of the answers in substance are that there have been two hearings within a period of less than three months by the judge of the district court upon the petitioner’s complaint against her husband for non-support, and a decision had thereon, and a refusal to receive another complaint from the petitioner unless some additional fact is presented by her.
M. Channéll, pro se.
No counsel appeared for the respondents.
If the single justice found these averments to be true, no writ of mandamus could issue.
Appeal dismissed without costs.
