Rugg, C.J.
This is a petition for a writ of mandamus to require the respondent to submit a certificate for the approval of the Attorney General for the abatement of an illegal income tax under G. L. c. 58, § 27, as amended by St. 1926, c. 287, § 1. By this section it is provided: *213“ If it shall appear that an income tax, a legacy and succession tax, or a tax or excise upon a corporation, foreign or domestic, was in whole or in part illegally assessed or levied, or was excessive or unwarranted, the commissioner may, with the approval of the attorney general, issue a certificate that the party aggrieved by such tax or excise is entitled to an abatement, stating the amount thereof. ... No certificate for the abatement of any tax or excise shall be issued under this section unless application therefor is made to the commissioner within two years after the date of the bill for said tax or excise, or for an amount exceeding the sum which in equity and good conscience ought to be abated under all the circumstances of the case. . . . The decision of the commissioner and attorney general shall be final. . . . This section shall be in addition to and not in modification of any other remedies.” The remainder of the section relates to the effect and means of enforcement of such certificate and has no bearing upon the issues here raised. The petitioner did not file any claim for abatement of the tax within six months after the date of the tax bill fixed by G. L. c. 62, § 43. After the expiration of that period but less than two years after the payment of the tax and the date of the bill therefor, the petitioner made application to the respondent for an abatement, which was refused.
Challenge is made of the right of the petitioner to maintain this form of relief on the facts here disclosed. It becomes necessary to examine somewhat critically governing statutes. The words “ If it shall appear ” in their context naturally mean “ if it shall appear to the tax commissioner.” This interpretation is confirmed by the further provision that the decision of the commissioner and the Attorney General shall be final. The ground upon which certificate may be issued is not illegality alone, but includes also an excessive or unwarranted levy. This remedy is not in modification of other remedies, such as those afforded by G. L. c. 62, §§ 43-47, but is in addition to them. That the tax commissioner is the one to whom reason for abatement must appear is confirmed by the re*214quirement of approval by the chief law officer of the Commonwealth before the certificate of abatement can be issued. No appeal is provided in said § 27 as amended from an adverse decision by the commissioner and Attorney General. There is careful provision for appeal in G. L. c. 62, §§ 43, 45, 47. Apparently the mischief intended to be remedied was the inability of the taxpayer to recover taxes paid by mistake, or to get relief against an illegal assessment after the expiration of the six months period, even though the commissioner and the Attorney General should be of opinion that there ought to be repayment or other relief. It is hardly a permissible construction to hold that the Legislature by this indirect method intended to extend to two years the time limited by G. L. c. 62, §§ 43-47, to six months after the date of the tax bill for contesting the validity of the tax. The history of said § 27 as amended makes this clear. The provisions of that section first were enacted by St. 1919, c. 146. The Attorney General had pointed out in his report for the year ending January 15, 1919, the lack of simple and inexpensive means for abatement and refund of certain taxes collected by the Commonwealth in cases where error or illegality was conceded. That part of his report was referred to the committee on taxation, which reported the bill subsequently enacted as said c. 146. Again, in his report for the year ending January 18, 1922, the Attorney General directed attention to the need of extending the provisions of G. L. c. 58, § 27, and including in the relief to be afforded legacy and succession, corporation and income taxes. That part of his report was referred to the committee on taxation, which reported a bill •embodied in substance in St. 1922, c. 382, whereby income as well as legacy and succession and corporation taxes were included within the scope of said § 27, and the period within which such relief could be granted was fixed at two years after the date of the tax bill. It is permissible to look to the history of a statute for light upon its purpose and meaning. Old South Association in Boston v. *215Boston, 212 Mass. 299, 304, 305. Loring v. Young, 239 Mass. 349, 368. The amendment made by St. 1926, c. 287, § 1, is not pertinent to the point here in issue.
The conclusion follows that, where the commissioner was of opinion at all times that there was no illegality in whole or in part in- the tax as levied, and that it was not excessive or unwarranted, and has considered the request for abatement on its merits, there is no ground for the issuance of a writ of mandamus.
The decision in Attleboro Trust Co. v. Commissioner of Corporations & Taxation, 257 Mass. 43, is readily distinguishable from the case at bar. That decision proceeded upon the finding (page 50) that the commissioner believed that “ the taxes assessed were in part at least illegal, and that his sole ground for denying the applications for abatement was that they were not filed within six months after the date of payment of the tax bills rendered as provided by G. L. c. 63, § 77.” This ground was held to be untenable in view of the express provision that such applications might be filed within two years. The effect of the decision was that the respondent ought to consider the applications on their merits and- not arbitrarily to refuse even to consider them unless filed within six months. That decision has no relevancy to the- facts here disclosed. The respondent in the case at bar did not decline to consider the application. He simply denied it. There is nothing in the record to indicate that the respondent did not honestly believe that the tax was legally assessed and warranted in every particular. Every presumption is to be indulged in favor of his good faith. Duffy v. Treasurer & Receiver General, 234 Mass. 42, 50. The circumstance that, to the knowledge of the respondent, a judge of the Superior Court upon a similar question had decided that the tax was illegal, does not entitle the petitioner to prevail. Notwithstanding that decision, it may still have appeared to the respondent, acting under a heavy sense of public duty, that the tax was legal.
The case at bar on its merits appears to be similar to *216Boston Safe Deposit & Trust Co. v. Commissioner of Corporations & Taxation, ante, 208, this day decided. That, however, does not entitle this plaintiff to the relief here sought.
Order dismissing petition affirmed.
