Appellants complain of variances (exceptions) granted by defendant board of zoning appeals without rhyme or reason. They say that the ordinance permitting the grant of variances is vaguely phrased and without specific standards (for ex*214ample, “unnecessary hardship” is a ground). In addition they complain that the board’s action here was “wholly unwarranted under the facts.” What, in truth, was the warrant for the board’s action? We are not told. The board says we do not have to be told.
Thus, under the board’s argument, the citizen gets it going and coming. Were the legislative standards followed by the board? There are no specific standards to be followed. What, then, are the reasons for the board’s finding the broad standard of “unnecessary hardship” to b'e satisfied? No one knows. No reasons are given. In other words it boils down to this: There is.unnecessary hardship because there is' unnecessary hardship, and, because there is unnecessary hardship, the standard (of unnecessary hardship) is satisfied.
Thus by mumbling an incantation the bureaucrat forecloses effective judicial review. What is there, for example, in the case before us, to review? After all, unnecessary hardship obviously is unnecessary hardship. Such was the factual determination. The legal determination is equally simple: The statute requires merely a case of unnecessary hardship. We found it, says the board. Q.E.D.
There are many things that this is, but we will fore-go elaboration at length, much as we would relish the task. But one thing it is not: due process. And if there is lack of due process it is utterly immaterial whether the complainant charges, as well, fraud, bad faith, mendacity, deceit, or any of the other of the lengthy litany of bad words.
Appellees Michael and Belle Chernick, defendants below, are the owners and contract purchasers of certain parcels of land located on the east side of' Wyoming between Joy road and McKenzie street in the city of Detroit. This area is classified as R-2 under the Detroit zoning ordinance. It is limited *215to the uses and structures falling within that classification, among which are multiple dwellings occupied by not more thab 8 families, approved by the city plan commission. On October 22,1958, Chernick. and his wife made application to the department of buildings and safety engineering for building permits which would allow them to • erect 2 multiple dwellings on this property. One of 'the proposed structures was to he an 18-unit structure on lots 127 through 133 of Robert Oaknian Land Company’s Bonaparte Boulevard subdivision; the other, a 20-Tinit structure on lots 136 through 143 of the same subdivision. This application was denied. Upon appeal to the board of zoning appeals, a variance was granted, on November 5, 1958, permitting the erection of the desired dwellings. On January 29, 1959, the appellant Improvement Association and others, plaintiffs below, filed a bill of complaint.in the Wayne county circuit court, in equity, to review the orders of the hoard of zoning appeals granting the variance. After argument, plaintiffs’ amended hill of complaint was dismissed by the lower court in separate motions filed by defendants Michael and Belle Chernick, and by defendants board of zoning appeals and department of building and safety engineering, and its commissioner. This appeal is taken from said order granting the defendants’ motions to dismiss.
The framework for zoning in the city of Detroit is provided by the Detroit zoning ordinance, passed pursuant to, and in compliance with, the enabling-act.1 If an individual wishes to use his property in a manner not permitted by the ordinance, a procedure is provided whereby he may obtain a “variance,” i.e., relief from compliance with the literal terms of the ordinance. Thus if the corner lot on a street has an irregular shape, because of confluence of streets, *216rather than the normal rectangular shape of the rest of the lots, a variation might conceivably be justified if the ordinance prohibits attached garages. But in such case, it will he noted, there is a hardship unique to this particular lot, not shared by all others. The power to grant the variance, as has been said, acts as a safety valve in such situations. But it is perfectly obvious that unless the power to grant variances is circumscribed with care we have not a safety valve in the boiler, but, as some writers put it, a leak.' Each owner’s desire to put his property to his own desired uses, gasoline filling station, apartment houses, or what not, if indulged, would simply mean no effective zoning whatever. It was well put in a recent study of the variance problem2 that:
“This ‘hidden zoning’ is unfair and will eventually undermine confidence in the protection that zoning is supposed to bring * * * Finally, the use of zoning as a positive and thus necessarily strict measure to aid in comprehensive city planning is impossible if the board of appeals constantly creates new problems of land use.”
A modification, or variance, then, may be granted, according to the terms both of the enabling act and of the ordinance, only when a literal enforcement of the provision in question would result in “unnecessary hardship or involves practical difficulties.” Here the board so found. Why? What is there in the situation or location of lots 127 through 133, and lots 136 through 143 that makes out a case of “unnecessary hardship” if defendants Chernick may not construct large multiple dwellings thereon? The board does not tell us. All we have is its conclusion, framed in the precise words of the ordinance, that there was “practical difficulty and unnecessary hard*217ship.” And at this juncture appellants make their attack, namely, that such finding was “a whimsical conclnsion, and wholly unwarranted under the facts,” that “the substance and effect of the decisions of the board of zoning appeals is to create ‘spot zones’ for the benefit of the defendants Chernick,” and that such alleged abuses have resulted since: “The power to grant exceptions [variances?] from literal enforcement of the ordinance by the board of zoning appeals is coupled with no guides or standards by which it shall exercise such authority.”
The delegation of authority to the board of zoning appeals to grant variances is found in section 20.7 of the zoning ordinance, City of Detroit, Official Zoning Ordinance (1957), § 20.7, p 24, which provides as follows:
“Where owing to special conditions a literal enforcement of the provisions of this ordinance will result in unnecessary hardship or involve practical difficulties, the board shall have power upon appeal in specific cases to authorize such variation or modification of the terms of this ordinance as will not be contrary to the public interest and so that the spirit of this ordinance shall be observed, public safety secured and substantial justice done.”
The above language respecting “unnecessary hardship” and “practical difficulties” is common to legislation in many States.3 Whether the twin concepts of hardship and impracticality must be defined more precisely, or are capable of more precise definition, is debatable. Most courts have approved delegation in such terms,4 although it has occasionally *218been rejected.5 Actually, however, the courts áre not far apart, for many of-them,' while upholding delegation framed in broad language, require not merely conclusions, but-a statement of the basis for the board’s findings of “unnecessary hardship” and “practical difficulty,” set forth in factual detail, thus preventing arbitrary, unguided action. In other words, the latter courts have distinguished an invalid delegation from an arbitrary exercise of authority validly delegated by requiring the board to set forth the reasons and facts upon which it bases its findings of “unnecessary hardship” or “practical difficulty.” In Stolz v. Ellenstein, 7 NJ 291 (81 A2d 476), the board of adjustment granted a variance after making a personal inspection but without disclosing on the record the facts and circumstances that impelled their action. The supreme court of New Jersey held that full disclosure on the record of the facts relied upon for the board’s findings was requisite, citing (p 297) an earlier opinion in Giordano v. City Commission of the City of Newark, 2 NJ 585, 589 (67 A2d 454, 455):
“No determination can be permitted to rest upon undisclosed findings or information dehors the record. If such could be the parties would be denied the essence of a hearing, they would be kept in ignorance of the things controlling the action of the board, and due process would be flouted. The rights of the parties can only be protected, both in the trial tribunal and on review, by a full disclosure on the record of the facts relied upon for the board’s findings.”
This requirement of full disclosure is particularly meaningful where, as here, the ordinance states6 that:
*219“The decision of the board in these and all other matters heard by it shall be final insofar as it involves discretion or the finding of facts.”
The courts are thus precluded from a reversal of the ruling of the board save upon the traditional grounds of showing of arbitrary action or a clear abuse of discretion. Such judicial function cannot, however, be discharged without a knowledge of the facts justifying the board’s statutory conclusion. The combination of the delegation of broad powers plus restricted review cannot be employed to prevent all recourse to the courts. It may be well to emphasize again, as in the past,- that it is neither the function nor desire of this Court to act as a fact-finding commission or a superzoning commission. Brae Burn, Inc., v. City of Bloomfield Hills, 350 Mich 425. Nevertheless we remain acutely sensitive to the capricious exercise of power, particularly when broadly granted.
It is our holding, on this branch of the case, that the board of zoning appeals must state the grounds upon which it justifies the granting of a variance. So far as Beardsley v. Evangelical Lutheran Bethlehem Church, 261 Mich 458, may be interpreted as inconsistent herewith it must be regarded as overruled. The extent and detail of such disclosure are obviously not capable of precise delineation.
The court of appeals of New York has required that, before a variance may be granted upon the ground of unnecessary hardship, the record must show: (1) that the land cannot yield a reasonable return if used only for a purpose allowed in that zone, (2) that the plight of the owner is due to unique circumstances and not to the general conditions of the neighborhood, and (3) that the use sought will not alter the essential character of the neighborhood. Matter of Taxpayers’ Association v. Board of Zoning *220Appeals of Town of Hempstead, 301 NY 215 (93 NE2d 645); Matter of Otto v. Steinhilber, 282 NY 71 (24 NE2d 851).7
Defendants next urge that plaintiffs’ court action was not “taken timely.” We are not specifically told what “timely” action would be. The trial court relied upon the 30-day limitation for court review of orders concerning nonconforming uses,8 obviously not here involved. It is a fair interpretation, however, of appellees’ briefs, that they rely upon the 5-day provision respecting “finality” of decision. The enabling act provides as follows :9
“The decision of such board shall not become final until the expiration of 5 days from the date of entry of such order unless the board shall find the immediate effect of such order is necessary .for the preservation of property or personal rights and shall so certify on the record.”
The meaning of the above is made clear upon examination of the history of the act. The original provision was simply that the decision of the zoning board of appeals should be final insofar as it involved discretion in the finding of facts.10 Clearly, this meant no more than that the decision of the board of appeals was final as to their proper findings ■of fact. It cannot reasonably be construed to state that the judiciary is to be foreclosed thereby from its hearing of the charge here made, of abuse of discretion. As one author phrases it :11
“There is always a minimum inherent judicial power of review of administrative action, and this is *221true with respect to zoning. * * * Accordingly, neither a State legislature nor a municipal council has authority to divest courts of their inherent power to review the action of a board of zoning appeals or other zoning administrative board, in order to determine whether the administrative action unlawfully impairs personal or property rights.”
The generally accepted meaning of such a proviso as that involved here is simply that the appellate court cannot act as a fact-finding commission. It cannot substitute its judgment for that of the board. The zoning ordinance, it will be noted, reads as follows :12
“The decision of the board in these and all other matters heard by it shall be final insofar as it involves discretion or the finding of facts.” (Emphasis added.)
Such provision undoubtedly reflects the correct interpretation of the words in the enabling statute. It cannot be held that the purpose of the 5-day provision was to create a period of limitation of such short duration, particularly in view of the complexity of pleadings and exhibits required for the proper presentation of involved zoning cases. As a practical matter, so interpreted it might well include all recourse to the courts. Moreover, if the 5-day provision creates a 5-day statute of limitation, by parity of reasoning, no court action whatever would be available if the order were given immediate effect, a procedure permitted by the enabling act under some circumstances.13 It is our conclusion that the 5-day provision does not limit the time for bringing an action.
There is nothing to the contrary in Jones v. DeVries, 326 Mich 126, Mitchell v. Grewal, 338 Mich *22281, or McVeigh v. City of Battle Creek, 350 Mich 214. None of them decided that there was only 5 days allowed for appeal to the courts when the order becomes “final” in 5 days, or (which would logically follow) that there is no access to the courts whatever if the order becomes final immediately. Such remains for this Court. Our opportunity, in fact, is unique.. We can first approve a legislative standard so vague as to require factual disclosures to justify action under it, nest deny the necessity for making any factual disclosure whatever, and, finally, having given the citizen nothing to review, tell him that he has 5 days to do it in, unless, of course, the order becomes “final” immediately, in which case he cannot get into court at all. We return to our opening thesis: Many things this is, all of them offensive. But one thing it is hot: due process.
Reversed and remanded to the circuit court for proceedings not inconsistent herewith. No costs, a public question.
