delivered the opinion of the Court.
This action was brought by respondent under the Declaratory Judgment Act, Judicial Code, § 274 (d), 28 U. S. C. § 400, to have declared null and void certain assessments on intangible personal property entered for the years 1940 and 1941 by the Collector of Hillsborough Township, Somerset County, New Jersey.

The jurisdiction of the federal court in New Jersey was invoked by
*622
reason of diversity of citizenship and the allegation that the taxing authorities had consistently, systematically and intentionally singled out respondent for discriminatory treatment in the assessment of taxes for which she was without remedy under the laws and decisions of New Jersey. It was prayed that the assessments be declared invalid as in contravention of the due process and equal protection clauses of the Fourteenth Amendment and of the provisions of applicable New Jersey statutes to which we will later refer. The District Court denied a motion to dismiss and gave judgment for respondent.
Sec. 267 of the Judicial Code, 28 U. S. C. § 384, provides that suits in equity shall not be sustained in the federal courts “in any case where a plain, adequate, and complete remedy may be had at law.” That principle has long been recognized as having “peculiar force” in cases where the federal courts were asked to enjoin the collection of a state tax.
Matthews
v.
Rodgers,
The Circuit Court of Appeals fully recognized the principle of the Huffman case, but concluded that the state procedure was not “speedy, efficient or adequate” to protect the federal right against discriminatory state taxation. It is around that conclusion that the first phase of this controversy turns.
The equal protection clause of the Fourteenth Amendment protects the individual from state action which selects him out for discriminatory treatment by subjecting him to taxes not imposed on others of the same class. The right is the right to equal treatment. He may not complain if equality is achieved by increasing the same taxes of other members of the class to the level of his own. The constitutional requirement, however, is not satisfied if a State does not itself remove the discrimination, but imposes on him against whom the discrimination has been directed the burden of seeking an upward revision of the taxes of other members of the class.
Sioux City Bridge Co.
v.
Dakota County,
It is argued, however, that in 1933 the New Jersey courts adopted a different rule when
Central R. Co.
v.
State Tax Dept.
(Thayer-Martin), 112 N. J. L. 5,
In the first place, the same judge who wrote the opinion for the Court of Errors and Appeals in the
Thayer-Martin
case wrote the opinion for the Supreme Court of New Jersey a year later in
Lehigh Valley R. Co.
v.
State Board,
12 N. J. Misc. 673,
This brings us to the second phase of the controversy. Neither the District Court nor the Circuit Court of Appeals decided the case on federal grounds. They held in reliance on
Duke Power Co.
v.
State Board,
129 N. J. L. 449,
Petitioner argues that it is clear from
Duke Power Co.
v.
State Board, supra,
that respondent had a remedy in the state tribunals for failure of petitioner to follow the procedure required by the New Jersey statutes and that the federal court should have required her to pursue it.
*628
We have held that where a federal constitutional question turns on the interpretation of local law and the local law is in doubt, the proper procedure is for the federal court to hold the case until a definite determination of the local law can be made by the state courts.
Railroad Commission
v.
Pullman Co.,
It follows
a fortiori
that the bill should not have been dismissed. As stated in
Greene
v.
Louisville & I. R. Co.,
Petitioner makes an extended argument to the effect that
Duke Power Co.
v.
State Board, supra,
is not a con
*630
trolling precedent on the local law question on which the decision below turned. On such questions we pay great deference to the views of the judges of those courts “who are familiar with the intricacies and trends of local law and practice.”
Huddleston
v.
Dwyer,
Affirmed.
Notes
The assessments call for tax payments of nearly $7,000,000 for each year as compared with the Township's budget of something like $97,000 annually. Prior to these assessments the net assessed valuation for taxation of all property assessed, both real and personal, in the Township amounted to $3,117,863 for 1940 and $3,139,020 for 1941. The resulting tax rate was 3.12 per cent for 1940 and 3.10 per cent for 1941. The additional assessments against respondent apparently would have increased the valuation of the township tax ratables by $221,940,438 for each of the two tax years, though it would not have affected the tax rates for those years.

Post
v.
Anderson,
111 N. J. L. 303,
N. J. Rev. Stat. § 54 : 3-20 provides in part, “On the written complaint of the collector, or any taxpayer of the taxing district or of the governing body thereof, that property specified has been omitted in the assessment, the county board, on five days’ notice in writing to the owner by the party complaining, and after due examination and hearing, may enter the omitted property on the duplicate by judgment rendered within ten days after the hearing, a transcript whereof shall be furnished by the board to the collector, who shall amend his duplicate accordingly.”
A different procedure is provided by § 54 : 3-20 for inclusion of property “omitted by the assessor.” For a discussion of the difference between the two types of assessments see Duke Power Co. v. State Board, supra, 129 N. J. L. pp. 452-455. At p. 455, the court said:
“If property in a taxing district is omitted by the assessor it must be added to the assessment before April 1st. Its addition decreases *627 the amount of taxes to be raised since the ratables are thereby increased. The taxpayer is not embarrassed. He knows he will have a tax to pay and is liable anyway even if the property was not included in the assessment. However, if property is added to the assessment after the rate has been fixed it gives rise to a municipal windfall. There is no harm in this if there were due notice and a fair hearing by the County Board and a judicial determination by it.”
Sec. 54 : 4r-58 provides:
“No tax, assessment or water rate imposed or levied in this state shall be set aside or reversed in any action, suit or proceeding for any irregularity or defect in form, or illegality in assessing, laying or levying any such tax, assessment or water rate, or in the proceeding for its collection if the person against whom or the property upon which it is assessed or laid is, in fact, liable to taxation, assessment or imposition of the water rate, in respect to the purposes for which the tax, assessment or rate is levied, assessed or laid.”
Sec. 54 : 4-59 provides:
“The court in which any action, suit or proceeding is or shall be pending to review any such tax, assessment or water rate shall amend all irregularities, errors or defects, and may if necessary ascertain and determine the sum for which the person or property was legally liable and by order or decree fix the amount thereof. The sum so fixed shall be the amount of tax, assessment or water rate for which the person or property shall be liable.”
The court in Duke Power Co. v. State Board, supra, 129 N. J. L. p. 457, stated that “the remedial statutes we do not find to have been a substitute for proper assessment. Their application has been only in instances where property has been omitted by the assessor, or has been assessed in the name of one other than the true owner.”
Ninety days are allowed. State Board of Tax Appeals, Rule V (c), CCH. Corp. Tax Serv. par. 89-505. The resolutions of the County Board attempting to make the assessments were entered June 26,1941.
The present bill was filed in July, 1941, the answer in September, 1941, and the motion to dismiss in November, 1941. The order denying the motion to dismiss was made in August, 1942.
It seems that under certain circumstances certiorari to the Supreme Court may be had in lieu of an appeal to the State Board of Tax Appeals. It was held in Schwartz v. Essex County Board, supra note 3, that lack of jurisdiction of the county board or irregularity in its proceedings may be tested by certiorari. 130 N. J. L. p. 178. And see State v. Clothier, 30 N. J. L. 351. But as we have seen, note 4 supra, it is a 'discretionary writ.
That case was decided by the Court of Errors and Appeals on March 9, 1944. The present case was decided by the District Court on July 14,1944.
