This is a petition for a writ of mandamus, brought to compel the respondents to reinstate the petitioner as a patrolman in the police department of the city of Cambridge, from which he was removed March 27, 1924, by the respondent McBride as chief of police of that city. Hereinafter McBride will be referred to as the respondent. The question, whether the petitioner received seasonable notice of his suspension is immaterial, as this proceeding is *196not brought to reinstate him because of such suspension, but on account of his removal from office.
The parties have agreed upon certain facts, from which it appears that the petitioner on January 20, 1924, was a patrolman on the Cambridge police force; that the respondent, previous to that date, had been appointed chief of the police department of that city, which appointment was confirmed by the city council, and by virtue thereof he has since acted in that capacity; that the respondent Quinn was and still is mayor of the city; that on January 23, 1924, the respondent received a written report from one Ginty, a lieutenant in the police department, to the effect that the petitioner, on the night of January 20, 1924, was intoxicated; that on January 23 the respondent suspended him from duty, and notice in writing of such suspension was delivered to him on the same date; that on January 24, the respondent received formal charges of intoxication and arrest therefor against the petitioner, made by one Leahy, captain of the petitioner’s district; that on February 1, 1924, the respondent appointed three police officers of the department as a trial board, and also notified the petitioner of the charges and that a hearing would be held thereon February 6, 1924; that thereafter on account of illness of the petitioner the hearing was adjourned from time to time until March 17, 1924, on which date he filed with the board written objections to the jurisdiction of the board to hear charges against him; that no further action was taken by it. On March 19, 1924, the respondent notified the petitioner that he contemplated removing him as a police officer for reasons specifically given to him in writing, and appointed March 26, 1924, for a hearing. At the time and place fixed for the hearing the petitioner appeared by counsel and objected in writing to the jurisdiction of the respondent to hear charges against him, but the latter proceeded with the hearing. On March 27, 1924, the respondent made his decision, finding the petitioner guilty upon the charges, and removed him from his position as police officer, and on the same day notice in writing, as required by law, was given to him of such decision. It is also agreed that since January 3, 1916, the *197city of Cambridge has been governed by the provisions of Plan B, St. 1915, c. 267, Part III, now G. L. c. 43. A copy (in part) of an ordinance of the city, entitled “An ordinance abolishing the department of public safety and establishing a fire department and a police department,” adopted June 4, 1917, as amended, is annexed to the agreed statement of facts.
By St. 1912, c. 611, the police and fire departments of the city of Cambridge were consolidated into what was called the department of public safety. That statute provided for the appointment by the mayor of a commissioner of public safety, and prescribed his duties relative to these two departments of the municipality. Under St. 1915, c. 267, entitled “An Act to simplify the revision of city charters,” the city of Cambridge since January 3, 1916, has been governed by the provisions of Plan B of that act, which is now embodied in G. L. c. 43. Under Part I, § 5, of the original act, now § 5 of G. L. c. 43, it is provided that the powers and duties of the officers and employees of any city adopting any of the plans provided for in the act shall remain as constituted at the time of the adoption of such plan, but the city council or other legislative body may at any time by ordinance, consistent with general laws, reorganize, consolidate or abolish departments, in whole or in part, and establish new departments. Acting under the authority conferred by this section, the city council by the ordinance hereinbefore referred to abolished the department of public safety and created police and fire departments. Section 4 of the ordinance is as follows: ‘ ‘ The Police Department shall be under the charge of a Chief of Police who shall.be the head of said department.”
The effect of the adoption of the ordinance was to abolish the office of commissioner of public safety provided for in St. 1912, c. 611, and create in its place police and fire departments with a chief of police as the head of the former. G. L. c. 43, § 5. St. 1891, c. 364, § 8, as amended by St. 1907, c. 565, § 2. Ellis v. Civil Service Commissioners, 229 Mass. 147, 151. Gordon v. Chief of Police of Cambridge, 244 Mass. 491, 493.
St. 1923, c. 242, changed the civil service laws relative to *198certain police officers in all cities except Boston, by inserting after § 42, of G. L. c. 31, two new sections, the first being § 42A, which provides in part that except as provided in section twenty-six, every police officer holding an office and classified under the civil service rules in any city except Boston shall hold such office during good behaviour and shall not be removed except after a full hearing, of which he shall have at least seventy-two hours written notice with a statement of the reasons for the contemplated removal; arid except upon a written order stating fully and specifically the causes therefor, made after a hearing as above provided for, and signed by the board or officer before whom the hearing is held. Any hearing under this section shall, if the police officer so requests in writing, be public and shall be held before the officer or board having power of appointment and removal. It is further recited in the statute that at any such hearing charges shall be made by the officer in command of the department or of the district where the police officer is on duty or by any person designated by the official in command of the department, and the police officer shall be allowed to answer such charges either personally or by counsel. He shall be notified in writing within three days after the hearing of the decision at such hearing. The statute contains other provisions which need not be referred to as they are not material to the questions involved in the case at bar.
The contention of the petitioner that he cannot lawfully be removed without a hearing before a trial board and a decision by it, in accordance with Rule 55 of the general regulations relative to the police force of the city, cannot be sustained. Rule 55 is subject to the provisions of the civil service laws. If adopted under St. 1912, c. 611, § 5, that statute expressly provides in § 7 that the authority therein conferred is subject to the laws relating to the civil service. It is apparent that the charges against the petitioner could not lawfully have been heard by the trial board; although notice was given to him that such hearing would be held, it was afterwards abandoned. See Gordon v. Chief of Police of Cambridge, supra.
*199St. 1923, c. 242, provides that the hearing of charges shall be held “before the officer or board having power of appointment and removal.” Rule 55, so far as it provides for hearing by a trial board appointed by the chief of police, is no longer in force because inconsistent with St. 1918, c. 247, now G. L. c. 31, §§ 43, 44 and 45, as amended by St. 1923, c. 242. Gordon v. Chief of Police of Cambridge, supra.
Under Rule 55 the trial board never had any power to remove but only to determine the question of guilt or innocence".
Ordinarily where adequate relief may be had by resorting to some other remedy, mandamus will not lie. If, as in the case at bar, a person contends that he has been wrongfully removed from an office classified under the civil service rules of the Commonwealth and is entitled to bring a petition for reinstatement in a police, district, or municipal court in conformity with the provisions of St. 1911, c. 624, as amended, now G. L. c. 31, § 45, he cannot maintain a petition for mandamus unless it appears that the remedy so given is not adequate. Butler v. Directors of the Port of Boston, 222 Mass. 5. Thomas v. Municipal Council of Lowell, 227 Mass. 116, 120. The statute above referred to provides that a person so removed may, within thirty days after the hearing upon which his removal is based, bring a petition in the district court praying that the action of the officer or board may be reversed by the court; and after notice it shall review such action, hear witnesses and affirm the decision of the officer or board, unless it shall appear that it was made without proper cause or in bad faith; in ' which case the decision shall be reversed, and the petitioner reinstated in his office without loss of compensation. Although the statute provides that “The decision of the court shall be final and conclusive upon the parties,” and as such decision, so far as it relates to questions of fact, will not be reversed, yet the parties are not deprived of the right.to have manifest errors of law corrected by a writ of certiorari. The Legislature did not intend by the words “final and conclusive” to leave the partiés without remedy if there were substantial errors of law apparent on the record of *200proceedings, depriving them of substantial rights. Swan v. Justices of the Superior Court, 222 Mass. 542. Commissioner of Public Works of Boston v. Justices of the Municipal Court of the Dorchester District, 228 Mass. 12.
As the remedy provided by G. L. c. 31, § 45, was adequate to protect the rights of the petitioner, the entry must be
Petition dismissed.
