Leto and others seek declaratory relief concerning the methods used in assessing property in Wilmington for 1964 taxes. In the companion case, the plaintiffs seek to restrain further action with respect to the 1964 tax assessment. A demurrer to each bill, addressed to the bill as a whole, was sustained. Each case has been reported by the trial judge for the decision of this court. See Gr. L. c. 214, § 30.
The bill in the Leto case alleges the following facts. In 1955 and 1956, the town established a “consistent scheme ... for ascertaining the fair cash value of all taxable real estate on a uniform, consistent, and equitable basis.” In 1962, the assessors doubled the valuations theretofore determined on each parcel “to approximate 100% of fair cash value for each such parcel.” The assessors voted for “a general revaluation to be conducted in 1965.” For the taxes of the year 1964, however, the chairman of the assessors “submitted revaluations made solely by him on only that land . . . zoned for commercial and industrial use. 2 These revaluations increased assessments “from 300% to 1,900%” on “20% of all taxable land in the town,” in-eluding land of the plaintiffs and were accepted by a major *146 ity of the assessors. 3 No similar revaluations were made of other land with minor exceptions. The most significant allegations are “ that the chairman of the [b]oard [of assessors] admitted that most residential land was assessed at a ratio of 79% to 82% of fair cash value and . . . was not generally revalued ’ ’ in 1964 while ‘ ‘ commercial and industrial land was purportedly assessed at full cash value” and actually at “substantially in excess of fair cash value.”
Upon the basis of earlier allegations the bill states as conclusions (a) that the valuations “cast a disproportionate tax burden” on the plaintiffs; and (b) that the assessors “deliberately and intentionally” have established and are pursuing a policy of assessing real estate “on a non-proportional basis . . . discriminatory against many taxpayers, including the” plaintiffs. The bill also states that the chairman of the assessors conducted this revaluation of land in industrial and commercial zones by himself without participation by other assessors who acted thereon without understanding the chairman’s methods, and in a manner different from that employed in prior years.
The bill in the Evans case (fn. 1) contains essentially the same allegations in substantially the same somewhat general and vague language. The allegations in both cases are diffuse and confusing and not made with the precision found in the careful statement of agreed facts described in
Bet-tigole
v.
Assessors of Springfield,
In the
Bettigole
case, and in
Opinion of the Justices,
The difficulties of allegation, proof, timeliness, or appropriate remedy, frequently encountered by those who bring proceedings to test the constitutional and statutory validity of all one year’s assessments and the whole tax levy for that year in a particular town, are illustrated by decisions discussed and cited in the
Bettigole
case. See e.g.
Dowling
v.
Assessors of Boston,
Other remedies, even if not wholly satisfactory,
4
afford some measure of relief from disproportionate assessments. See e.g. Gr. L. c. 59, § 59 (as amended through St. 1963, c. 125), § 64 (as amended through St. 1956, c. 544), § 65 (as amended through St. 1945, c. 621, § 6); Gr. L. c. 60, § 98. The existence of such remedies sometimes has been taken into account in determining whether a court should grant
*148
relief in equity or by extraordinary writ. Even in the
Bet-tigole
case,
The
Bettigole
case establishes that a court of equity may prevent the enforcement of the whole of an illegal city or town tax assessment for a given year. The authorities just cited, however, make it plain that such somewhat extraordinary relief will not be granted (1) unless basic facts exist showing essentially a deliberate and substantial violation
5
of the constitutional and statutory requirements that property tax valuations shall be proportional; (2) unless the plaintiffs show themselves to be directly, significantly
*149
and adversely affected; (3) unless relief by ordinary abatement procedures or by an action at law will be seriously inadequate; and (4) unless equitable relief is shown to be practicable
6
and appropriate in the sense that the assessors’ constitutional and statutory violations are so great as to warrant seasonable equitable interference with normal tax assessment and collection processes. There must be clear and precise allegation of facts which if proved will satisfy each of the foregoing prerequisites, if a bill in equity seeking such drastic relief is to be good against demurrer. No intendment will be made in favor of the allegations of such a bill in the face of a demurrer. See
Mairs
v.
Madden,
Viewed in the light of these requisites, the diffuse and confusing allegations of these bills, although they may suggest that the assessors’ procedures were improper or likely to result in some degree of nonproportional assessment, do not state a case for equitable relief. The allegation that land of the plaintiffs was revalued in 1964, perhaps, may be sufficient (taken with other allegations) to state discrimination against them as owners of commercial or industrial land, but even this allegation is largely by implication. We think, however, that the allegations concerning what the assessors have done are fatally indefinite and incomplete when they should have been full and incisive. Even if the allegations concerning the adoption of the 1955-1956 valuation scheme imply that thereafter the assessments were for a time proportional, it does not necessarily follow that they remained so as late as the 1962 doubling of the assessments. Indeed, it is alleged that the board in 1964 decided that a *150 new revaluation in 1965 was necessary and that the hoard chairman started in 1964 such a revaluation 11 on only that land ... in the areas zoned for commercial and industrial use.” It does not appear that these revaluations were not necessary to bring the assessments of the revalued land to the level of fair cash value, or that the proposed 1964 assessments are not more nearly proportional than those in effect in 1963. The allegation that some land assessments were increased as much as 300% to 1900% suggests that the preexisting valuations had become very much out of line. It is not clearly alleged whether any structures (as distinguished from land, see fn. 3) were revalued in 1964 and it is not explicitly alleged that the aggregate assessments of land and structures will not be proportional, although, perhaps, that may be stated by implication.
The allegations most nearly setting out a violation of the principles stated in the
Bettigole
case are the general conclusions quoted above that “most residential land was assessed at . . . 79% to 82% of fair cash value” and that “commercial and industrial land was purportedly assessed at full cash value,” or more. Obviously no deliberate policy of assessing residential land and structures at 80% of fair cash value and commercial and industrial land and structures at 100% (or more) of fair cash value will comply with constitutional and statutory requirements. If alleged clearly and proved seasonably, equitable relief against such an assessment scheme should be granted on the principles declared in the
Bettigole
case. The basic specific facts alleged (see
James Constr. Co. Inc.
v.
Commissioner of Pub. Health,
In the light of these considerations we think that the demurrers were properly sustained. The allegations of basic facts in these bills do not show sufficiently that there is present occasion for substituting declaratory or injunctive equitable relief for the usual statutory remedies. 9
Interlocutory decree sustaining demurrer affirmed in each case.
Notes
The bill says, ‘ ‘ The revaluations distinguished . . . [such] land from . . . all other taxable classes of real estate by not subjecting such other land to similar revaluations and . . . did not include revaluations of land used commereially and industrially . . . located in other zoned areas . . .
It is also alleged that one or more of the assessors have admitted that a revaluation only of land zoned for industrial and commercial use was adopted, that changes in other valuations were mainly based upon a limited number of sales and upon specific improvements of particular parcels, and that no similar revaluation was made of nonindustrial and noncommercial land. By implication at least the plaintiffs seem to have alleged that there has been “ failure or refusal ... to revalue [at all] commercial and industrial structures and improvements,” presumably as distinguished from commercial and industrial land. After reciting these and other allegations, mentioned in the body of this opinion, the plaintiffs '1 allege [all of them] as facts.”
The Carr ease, at pp. 92-93, the Stone ease, at pp. 250-251, and the Bettigole ease, at p. 237, suggest respects in which the usual statutory remedies may prove to be inadequate. As we said in the Stone ease (at p. 251), “an assessment may be excessive in a constitutional sense, not because land is assessed at a figure in excess of its fair cash value, but because it is assessed a.t [fair cash value or] less than fair cash value while the land of other taxpayers is intentionally assessed at . . . lower percentages of the full, fair cash value of such land.” At p. 250, we pointed out that applications for abatement of real estate taxes have often been “dealt with in relation to whether the taxpayer's land is assessed for more than its fair cash value and without regard to whether other property is assessed at its full, fair cash value. ’ ’
In essence it must be shown that the assessors are taking action intended to circumvent the constitutional and statutory requirements, or that such circumvention is the natural and probable consequence of this action.
This does not mean that questions of discretion whether to grant relief axe open upon demurrer. See
Massachusetts Chiropractic Laymen’s Assn. Inc. v. Attorney Gen.
Indefiniteness and lack of clarity also characterize the allegations concerning the conduct of the chairman of the assessors in his relation to his colleagues. These do little more than to suggest, in very general terms, that the *151 full time chairman’s revaluation activities (see St. 1950, c. 592, § 13) were approved by the chairman and one other assessor, without as much understanding by that assessor of the chairman’s methods or as much exercise of intelligent independent judgment by him, as would have been desirable.
We assume that a general revaluation of a whole town normally will require a period of time and that most communities endeavor to maintain some stability in assessments, from year to year, subject to a continuing process of readjustment to reflect not only changes in properties but also clearly discernible long term trends in market conditions as distinguished from sporadic or short term fluctuations of a few prices.
Although the trial judge in sustaining the demurrers denied leave to amend the bills, this is a case where it would be appropriate for the Superior Court to exercise discretion to allow further prompt amendments of the bills, if the obscurity of the bills here discussed can be promptly and adequately corrected.
