In May, 1978, Robert T. Vickey (defendant) successfully sought, pro se, to have a Superior Court judge order the sealing of his record of conviction. The office of the Commissioner of Probation (Commissioner) refused to comply. On July 19,1979, Vickey filed a motion seeking an order to compel the Commissioner to seal his record. On September 24, 1979, the same judge vacated his order of May, 1978, and denied Vickey’s motion. Vickey appealed. We transferred the appeal from the Appeals Court on our own motion and now affirm.
The facts may be summarized as follows. On December 1,1972, Vickey pleaded guilty to a charge of making a false bomb report, in violation of G. L. c. 269, § 14. At the time of this plea Vickey was twenty-three years old and without any prior criminal record. He received a suspended two-year sentence to a house of correction. On May 16, 1974, some seven months short of the two-year probation term, a Superior Court judge terminated and dismissed Vickey’s probation. On May 10, 1978, the Governor, with the advice and consent of the Council, granted Vickey a full pardon. G.L.c. 127, § 152.
The motion judge ruled that Vickey’s record could not be sealed pursuant to the provisions of G. L. c. 276, §§ 100A, 100C. 1 The judge ruled further that a pardon is not anal *764 ogous to a dismissal and that the case did not require the exercise of ancillary or inherent jurisdiction. We agree.
The defendant concedes that his request does not come within the provisions of G. L. c. 276, §§ 100A and 100C, but argues that G. L. c. 6, § 171,
2
recognizes a judicial power to order sealing or purging without preemption by the provisions for sealing in G. L. c. 276, §§ 100A and 100C. He contends further that this case presents the same policy considerations which underlay our balancing of the competing interests in
Police Comm’r of Boston
v.
Municipal Court of the Dorchester Dist.,
To the extent that the defendant relies on G. L. c. 6, § 171, we note it refers only to the “purging” of certain records. We treat the term “purging” as synonymous with “expungement.” As noted in Police Comm’r, expungement is the total removal of a record “so that no trace of the information remains.” Id. at 648. Sealing, the relief sought here, “refers to those steps taken to segregate certain records from the generality of records and to ensure their confidentiality to the extent specified in the controlling stat *765 ute.” Id. Despite considerable confusion in applying this terminology, 3 the Massachusetts Legislature made clear its knowledge of the distinctions involved by changing the language of G. L. c. 94C, § 44, from “expungement” to “sealing.” St. 1973, c. 533, § 1. The principal benefit which accrues to an ex-offender whose record is sealed is that he may state on employment applications that he has no record of arrest or conviction, and the Commissioner must corroborate this statement. G. L. c. 276, § 100A. Sealed records may nevertheless be made available to “any law enforcement agency, any court, or any appointing authority.” G. L. c. 276, § 100A, as amended through St. 1975, c. 278. We noted also in Police Commr that specific legislative authorization for sealing extends only to court and probation records, but that G. L. c. 6, §§ 167-178, extends the confidentiality protection to all criminal records. See 374 Mass, at 650, 653.
We consider first the defendant’s argument that the modification of G. L. c. 6, § 171, subsequent to the enactment of G. L. c. 276, §§ 100A and 100C, impliedly repealed those sections. In 1977 the Legislature added a third paragraph to G. L. c. 6, § 171. St. 1977, c. 691, § 3. Its failure at that time to modify the already existing statutory provision in § 171
(b)
regarding purging “by the order of any court of competent jurisdiction,” cannot be interpreted, as Vickey suggests, to repeal or affect the application of the sealing statutes. We cannot read such an intent from the mere fact of legislative silence. More importantly, our perusal of the language of G. L. c. 276, §§ 100A and 100C, in juxtaposition with G. L. c. 6, § 171, shows no contradiction or repugnance. The three sections are easily harmonized as serving the legislative purpose to protect individuals from unnecessary and overbroad dissemination of criminal record information. See
Commonwealth
v.
Hayes,

*766
Mass. 505, 510-512 (1977);
Board of Educ.
v.
Assessors of Worcester,
We turn now to the defendant’s claim that the judge had the power to compel the sealing of the defendant’s records under the court’s inherent or ancillary powers, as described in
Police Comm’r of Boston
v.
Municipal Court of the Dor-chester Dist.,
By contrast, Vickey seeks the sealing of his conviction record despite an applicable and statutorily prescribed waiting period. The defendant acknowledges that he is ineligible for sealing under any statutory provision but urges this court to read into G. L. c. 6, § 171, a judicial power to bypass the plain language of G. L. c. 276, § 100A. The defendant errs in his intimation that the court in Police Comm’r found judicial power under § 171. We stated that § 171 does not grant the power to issue orders to purge, or to seal. General Laws c. 6, § 171, is “not to be read as a grant of power to issue such [purging] orders, but as recognition of the authority of courts to act to the full extent of their previously existing jurisdiction.” 374 Mass, at 650-651. This general language does not undercut the specific language of the sealing statutes.
*767
Here the meaning of G. L. c. 276, §§ 100A and 100C, is plain on its face. The types of dispositions for subsequent offenses which do not abridge the right to sealing of a prior record are set forth with particularity in § 100A: not guilty, dismissed for want of prosecution, dismissed at request of complainant, nol-prossed, no bill. Section 100C specifies the types of dispositions for which a court may direct immediate sealing of records: nolle prosequi, dismissal. The defendant apparently contends that the omission of the term “pardon” from these sections creates a statutory gap similar to the one we saw in
Police Comm’r.
This suggestion would require our stretching the statutory words beyond their fair meaning. See
Holbrook
v.
Randolph,
Because there was a conviction in his case, Vickey seems to suggest a quid pro quo: dismissal in Police Comm’r yielded expungement; therefore, the pardon in his case should result in immediate sealing. In making this argument Vickey overlooks the significant distinction between a finding of not guilty or a dismissal of charges, or other similar disposition, and a pardon. We turn now to an examination of the various meanings which may attach to an executive grant of a pardon.
*768 a. The history of pardons. The law of pardons has been somewhat obfuscated by the failure to differentiate a pardon for innocence from a pardon for other reasons. See Weihofen, Pardon: An Extraordinary Remedy, 12 Rocky Mtn. L. Rev. 112 (1940). Professor Weihofen points out that pardons have issued for such highminded purposes as correcting erroneous convictions or maintaining political harmony, and for the merely practical purposes of relieving overcrowded prison conditions, rewarding a prisoner’s reform or his turning State’s evidence, celebrating a holiday, or doing a political favor. Id. at 113. Among these various possibilities, the pardon invoked to correct the wrongful conviction of innocent persons is an anomaly which has occurred only rarely. See id. at 112; Belli, The Story of Pardons, 80 Case & Com. 26, 26-30 (May-June, 1975); Wil-liston, Does a Pardon Blot out Guilt?, 28 Harv. L. Rev. 647, 648-650 (1915); S. Stafford, Clemency: Legal Authority, Procedure, and Structure xiv, xvi (1977).
From its roots as mitigation for the rigid and harsh early English criminal law, the pardon has today become primarily a tool for rehabilitation of convicts and has been inextricably interwoven with the parole system. See Wei-hofen, supra at 114-115. In Massachusetts the pardoning power is defined in Part II, c. 2, § 1, art. 8, of the Massachusetts Constitution, as amended by art. 73 of the Amendments, and the Legislature has set forth the terms and conditions under which a prisoner or convict may apply for a pardon in G. L. c. 127, §§ 152-157.
Vickey’s pardon was one of eighty-four similar pardons issued in 1978 by the Governor upon the recommendation of the Advisory Board of Pardons. 1979 Senate Doc. No. 2030, at 70. Not in any sense an extraordinary remedy arising out of unusual circumstances, Vickey’s pardon resulted from the regular functioning of the penal and rehabilitative process.
The pardoning power has belonged throughout history to the executive branch. It functions in total independence of the judiciary. See

Glisson,
The truism that a pardon does not wipe out guilt has consequences for law enforcement and other public informational needs, which this court discussed at length in
Commissioner of the Metropolitan Dist. Comm’n
v.
Director of Civil Serv.,
In light of these authorities illustrating the meaning of a pardon, we cannot conclude, as the defendant argues, that a pardon is the equivalent of the dispositions described in G. L. c. 276, §§ 100A, 100C, or the dismissal with prejudice involved in Police Comm’r. The pardoning statute itself confirms our view. It extends clemency on the one hand, G. L. c. 127, § 154, but provides for re-arrest if necessary, G. L. c. 127, § 155. Reading G. L. c. 276, § 100A, in conjunction with G. L. c. 127, §§ 154 and 155, we find that in issuing a pardon the executive branch may make a public statement of confidence in the pardonee’s prospects for reform, but the sealing statute requires an actual time-proven demonstration of that reform.
The recordkeeping provisions of G. L. c. 6, the pardoning statutes, and the sealing statutes bespeak a uniform legisla *772 tive and executive policy — to protect the privacy interests of the ex-felon and to maximize his restoration to normal citizenship. Unlike the situation of the juvenile in Police Comm’r, this appeal does not present an instance of legislative silence. Rather, the statutory scheme of parole and pardon, as well as the legislative definition of rehabilitation which entitles a convicted person to have his record sealed, are spelled out by the Legislature in terms which require no judicial enlargement.
We affirm the denial of the defendant’s motion to compel the Commissioner to seal his record.
So ordered.
Notes
General Laws c. 276, § 100C, inserted by St. 1973, c. 322, § 1, states in relevant part: “In any criminal case wherein the defendant has been found not guilty . . . or a no bill has been returned by the grand jury, or a finding of no probable cause has been made by the court, the defendant may . . . request that the commissioner seal said court appearance and *764 disposition recorded in his files. . . .
“In any criminal case wherein a nolle prosequi has been entered, or a dismissal has been entered by the court, except in cases in which an order of probation has been terminated, and it appears to the court that substantial justice would best be served, the court shall direct the clerk to seal the records of the proceedings in his files. The clerk shall forthwith notify the commissioner . . . who shall likewise seal the records of the proceedings in their files.”
General Laws c. 6, § 171, as amended by St. 1977, c. 691, § 3, reads in pertinent part: “The board shall promulgate regulations (a) creating a continuing program of data auditing and verification to assure the accuracy and completeness of criminal offender record information; (b) assuring the prompt and complete purging of criminal record information, insofar as such purging is required by any statute or administrative regulation, by the order of any court of competent jurisdiction, or to correct any errors shown to exist in such information; and (c) assuring the security of criminal offender record information from unauthorized disclosures at all levels of operation” (emphasis supplied).
See Gough, The Expungement of Adjudication Records of Juvenile and Adult Offenders: A Problem of Status, 1966 Wash. U.L.Q. 147,149 (legislation treating access to criminal record suffers “extreme lack of uniform terminology”).
For discussion of the contemporary relevance of this aspect of the pardoning power, see Belli, The Story of Pardons, 80 Case & Com. 26, 26-27 (May-June, 1975) (technical application of law may produce unjust or unpopular results in courts); S. Stafford, Clemency: Legal Authority, Procedure, and Structure xv, xvi (1977) (clemency may mitigate harshness of determinate sentencing statutes or of death penalty).
