This is a petition for a writ of error. Writ of error and scire facias have issued. The case is here upon the record of the district court of Chelsea duly returned and certified. It appears therefrom that the plaintiff in error was duly arrested and brought before that court on March 5, 1923, on a complaint charging him with having committed the crime of larceny, when he was arraigned and pleaded guilty; that by agreement the case was continued, first until March 12, 1923, and then until March 17, 1923, when he was adjudged guilty and ordered committed to the house of correction for the term of one year and “ sentence was suspended and said Finer was placed in the care of the probation officer. On December 8, 1923, a default warrant for violation of probation was issued and said Finer was brought before said court April 2, 1924, and said sentence *496was revoked and Finer was committed.” Both sides assume that he was committed on a new sentence. The plaintiff in error in his petition and in his brief states that the new sentence was for a period of one year from April 2, 1924. The case is considered on that footing.
The question to be decided is whether the district court had power to make an indefinite suspension of sentence and to place the plaintiff in error on probation without fixing a definite time for the period of probation, and then at .a later time to reimpose the same sentence.
District courts, since St. 1916, c. 174, § 2, and now, are “ courts of superior and general jurisdiction with reference to all cases and matters in which they have jurisdiction . . . and the like presumption shall be made in favor of proceedings of such courts as would be made in favor of proceedings of other courts of superior and general jurisdiction.” G. L. c. 218, § 4. Therefore, the statement in Commonwealth v. Maloney, 145 Mass. 205, at page 211, is now applicable to the case at bar: “When a case is pending in a permanent court of general jurisdiction, with stated terms, in which continuances are from term to term, a defendant may waive the formal entries of continuance, and consent that the case may remain in court without such entries until asked for by either party.” The abolition of stated terms of court, St. 1897, c. 490, G. L. c. 213, § 4, St. 1897, c. 431, G. L. c. 218, § 38, does not affect the pertinency to the case at bar of the general principle here declared.
The establishment of the probation system and the limitations upon its exercise are.set forth in the statutes. The bounds imposed by the statute must be observed when the machinery provided by the probation system is invoked. It is provided by G. L. c. 279, § 1, that after suspension of sentence a district court may order that the person convicted “ be placed on probation for such time and on such terms and conditions as it shall fix.” These words are in substance the same as those empowering the Superior Court to place upon probation a person convicted before it. G. L. c. 276, § 87. These words import definiteness and specification as to the time of the probationary period. There is *497reason for such definiteness and specification when a person has been convicted and sentenced. The general safety of society may require more stringent supervision of such a person than of one merely charged with crime but not convicted. These words are different from the words of said § 87 authorizing the probation before conviction of those charged with crime. This difference of phraseology cannot be regarded as immaterial or wanting in signification.
Failure to conform to the statute with respect to stating the period of probation does not affect the substantial rights of the plaintiff in error in his present plight. He is not entitled to be discharged from custody. It does not affect the validity of his sentence or his commitment in execution thereof. His original sentence was valid. If he was dissatisfied with it, he had opportunity for appeal before the suspension of his sentence. After accepting the advantage extended to bim by the law solely for his benefit, he could no longer ask for revision of it or complain of its terms. Mariano v. Judge of District Court of Central Berkshire, 243 Mass. 90. The plaintiff in error has never served his sentence. It was suspended indefinitely. There was no infraction of the statute in such extension. Gabis, petitioner, 240 Mass. 465. He accepted without objection the benefit thus afforded. He took advantage of the probation. Simply because there was an informality with respect to an incidental aspect of the probation following that suspension, the convict is not enabled to escape punishment. Commonwealth v. McGovern, 183 Mass. 238. Whatever may be said about the probation, the conviction and sentence stood unaffected. It was lawful for the plaintiff in error to be brought before the court for execution of that sentence pursuant to that conviction. The case stands no differently in these circumstances with respect to execution of sentence than a complaint or indictment placed on file. At any appropriate time it may be brought forward for execution of sentence. Commonwealth v. Dowdican’s Bail, 115 Mass. 133, 136. King v. Commonwealth, 246 Mass. 57. Marks v. Wentworth, 199 Mass. 44.
No error of law of which the plaintiff in error can complain is disclosed on this record.
Judgment affirmed.
