The County of Brown and city of New Ulm appeal from a decision of the trial court determining that the assessment procedures by which the real estate taxes payable in 1971 in the city of Nеw Ulm were determined were null and void and of no effect. Respondents, by notice of review, appeal the determination of the trial court that the holding in this case was not apрlicable to the real estate taxes payable in 1972. We affirm.
*382 This matter arose on petitions of 134 taxpayers in the city of New Ulm seeking to set aside the assessment of taxable vаluation of their property made in the year 1970, which was the basis for real estate taxes payable in 1971. The issues relating to assessment procedures were severed and consоlidated for trial. Only these proceedings are now before us.
On October 14, 1969, after making a study of property valuations within the city limits, the city council of New Ulm decided to reassess the city’s rеsidential property. Four methods of assessment were considered by the council, namely, (1) an across-the-board-percentage increase; (2) contracting with a private firm to make the reassessment; (3) contracting with the state to make the reassessment; and (4) having the city assessor perform the reassessment.
The city assessor reported at this meeting that thеre were approximately 6,000 parcels of taxable properties within the city limits and that his office could complete the reassessment over a 4-year period by hiring two tо four additional persons. The city council decided to have the local assessor proceed with the assessment and adopted his proposal of dividing the geographiсal areas of the city into various segments which would be completed one at a time and placed upon the tax rolls as completed. The council was aware that such a method would result in temporary discrimination during the period of the reassessment.
The reassessment began on October 24, 1969, in the “Hilltop” area of the city. This area consisted of 600 homes and 300 vacant lots which the assessor considered to be the most inequitably assessed area in the city based on previous assessments. Originally it was contemplated that only this area wоuld be completed in time for the 1971 tax assessment, but an additional 400 parcels were reassessed in another segment and the results were given to the board of equalization on July 15, 1970.
The city аssessor had hired two people to assist in doing the measuring of homes involved. He testified that as their input was all that he could keep up with, he did not hire additional per *383 sons to assist in meаsuring the homes. The entire assessment procedure was completed prior to January 1, 1972.
It is unchallenged that the properties reassessed paid an increased percentage of the real estate taxes for the tax year 1971. The 134 petitioners paid a composite 55.66-percent increase in taxes over the previous years. Since the mill rate varies inversely with the assessment value, other property in the city paid the same or less tax than in' previous years.
The trial court found that the revaluation of residential real estate for assessment purposes for the year 1971 constituted a systematic, arbitrary, and intentional overvaluation of the properties of the petitioners in comparison to the other properties of the same class in' the city and resulted in an unfair and discriminatory tax against the real estate of the petitioners contrary to the Federal and Statе Constitutions. In subsequent proceedings, the court further found that under Minn. St. 278.01 1 the assessment for each assessment period constitutes a proper basis for appeal and that the petitiоn for determination of the propriety of the assessment must be filed on or before June 1 of each year in which the tax becomes payable.
The initial issue presented on this aрpeal is whether portions of property located in a taxing district may be revalued and reassessed upon the tax rolls prior to completion of the revalua

tion and reassessment of all property located within the taxing district. We have previously held that, while counties do not constitute taxing districts, other units of government do. In re Petition of Dulton Realty, Inc. v. State,
“* * * it is noticeable that while cities, villages, and towns are referred to as taxing or assessment districts in various statutes, nowhere is there any reference to the county as such a district.”
In In re Petition of Hamm v. State,
“It follows that discrimination in the imposition of the tax burden, resulting from systematic, arbitrary, or intentional undervaluation of some property as compared to the valuation of other prоperty in the same class, violates the uniformity clause of Minn. Const, art. 9, § 1, and the equal-protection clause of U. S. Const. Amend. XIV, even though the property so discriminated against be not assеssed higher than its fair market value adopted as a uniform basis in the making of assessments.”
More recently, we have again considered.this matter in Johnson v. County of Ramsey,
We hold that all property which is to be revalued in a separate taxing district must be placed upon the tax rolls at the new valuations at the same time.

It is constitutionally invalid to divide the taxing district into geographical segments and replace portions of the taxable parcels of property upon the tax rolls even though the scheme of revaluation is to be accomplished within a reasonable time. Such a result is consistent with the dictum of our decision in Johnson where we said (
“From a strictly technical standpoint, if we were to consider Ramsey County as a single taxing district, there might be some difficulty in justifying disparity, even temporarily, under our constitutionаl requirement that property of similar nature be taxed equally, * *
2. Since the same assessment period is involved, petitioners seek review of the trial court’s holding that the ruling as to the validity оf the 1971 taxes would not be extended to the 1972 taxes. The trial court correctly found that the statutory proceedings under Minn. St. 278.01 are the exclusive remedy of the taxpayer. Evanson v. Commissioner of Taxation,
Affirmed.
Notes
Minn. St. 278.01 provides: “Any person having any estate, right, title, or interest in or lien upon any parcel of land, who claims that such property has been partially, unfairly, or unequally assessed, or that such parcel has been assessed at a valuation greater than its real or actual value, or that the tax levied against the.same is illegal, in whole or in part, or has bеen paid, or that the property is exempt from the tax so levied, may have the validity of his claim, defense, or objection determined by the district court of the county in which the tax is leviеd by serving copies of a petition for such determination upon the county auditor, county treasurer, and the county attorney and filing the same, with proof of such service, in the officе of the clerk of the district court on or before the first day of June of the year in which such tax becomes payable.”
Our holding neither interferes with nor limits the duties and responsibilities of boards of review under Minn. St. 274.01.
