In the leading state decision, Thornburg v. Port of Portland, 233 Or. 178, 376 P.2d 100 (1962), the Oregon constitutional provision was similar to that of the United States Constitution. The Oregon Supreme Court took note of the line of Federal cases requiring direct overflight, but explained that their rationale was circular because '(t)he majority (in Batten v. United States, Supra) said in effect that there is no taking because the damages are consequential, and the damages are consequential because there is no taking.' 233 Or. 187, 376 P.2d 104. The Oregon court in rejecting the majority opinion of the Batten court and following the dissent of
Chief Judge Murrah, stated:
'When this action is analyzed in this manner, the term 'substantial' is of dubious relevancy or utility. It connotes a balancing of the interests of the public in general against those of the individual. Inherent is the idea that the individual must bear a certain amount of inconvenience and loss of peace and quiet as the cost of living in a modern, progressing society. In eminent domain, and in inverse condemnation, such a balancing does not have to be accomplished as a distinct process, simply because the individual seeks no recovery for his individual suffering, damage, loss of quiet, or other disturbance. These elements of damage are cognizable in a tort action, and such a balancing would thus be necessary. But in inverse condemnation the measure of recovery is injury to market value, and that alone. 'Therefore, the balance of interest inherently struck in this type of action comes about in the following manner. If the individual is unusually sensitive, and sustains a greater injury than might be suffered by the general public from such interference, the public interest in maintaining the flights leaves him to one remedy -- to sell his property and move. This is no different than it would be had his land been condemned for forced sale to the state. But whichever way the state exacts such a 'sale,' it must pay the individual the amount he suffers in the diminishment of the value of his land, as reflected by the decrease in the amount he can receive in a sale to a willing buyer. Such lowering of market value reflects not the personal injury to the individual, but the lesser desirability of the land to the general public; I.e., to a ready, able, and willing buyer. When the land of an individual is diminished in value for the public benefit, then justice, and the constitution, require that the public pay.
'In the above manner, the interests which would otherwise be protected by the requirement of a 'substantial' injury are vindicated in two distinct ways. First, where there is only an injury of the extent such that it should be called or labeled 'incidental,' no measurable or provable decline in market value could be expected traceable to the flights. Recovery would not be forthcoming, but not because of some arbitrary rule set for convenience in administration of justice, but because of an inability to prove damages according to the common and well understood rules of suit. Second, and even more significant to the balancing problem, the smaller the provable decline in market value, the slighter the burden cast upon the public in paying for it. Surely the protection of the public interest does not entail the refusal of Small claims on the ground that the burden to the public is not great enough to pay for!' Martin v. Port of Seattle, 64 Wash.2d 309, 318, 391 P.2d 540, 546 (1964).
[FN 2] Compare the procedure used by the Supreme Court of California in the case of Nestle v. City of Santa Monica, 6 Cal.3d 920, 101 Cal.Rptr. 568, 496 P.2d 480 (1972).
What, then, are the guidelines to be followed by the trial court, on remand, in reaching its initial determination as mandated by Thomsen? It should be pointed out initially that the Minnesota Constitution requires compensation where private property is taken, destroyed, or damaged. Any statement of what constitutes 'property' can only be nebulous at best. Not every economic, social, or other interest or advantage is a property right, the taking of which must be compensated. As the United States Supreme Court pointed out in United States v. Willow River Power Co., 324 U.S. 499, 502, 65 S.Ct. 761, 764, 89 L.Ed. 1101, 1107 (1945), only those economic advantages which have the law back of them are property rights. Thus, to begin by arguing that compensation must be paid because a property right has been taken really merely raises the question that must be ultimately answered. Property is more than the physical thing -- it involves the group of rights inhering in a citizen's relation to the physical thing. Traditionally, that group of rights has included the rights to possess, use, and dispose of property. [FN 3] See, United States v. General Motors Corp., 323 U.S. 373, 378, 65 S.Ct. 357, 359, 89 L.Ed. 311, 318 (1945). Petitioners in this case do not allege that they have been dispossessed by MAC's operations. They allege that their right to use the property without undue interference has been infringed and the decrease in market value due to defendant's operations has deprived them of their right to dispose of their property for a fair price. The right to use one's property in relative freedom from irritating noise and interference can hardly be disputed in view of present-day living conditions where a great deal of governmental and private effort is spent on planning and zoning our cities in an effort to improve the quality of life. These societal efforts to protect certain land uses from irritating interferences, then, indicate that the use and enjoyment of one's property without unduly irritating noise, vibrations, and gaseous fumes have arisen to the status of a property right for which a property owner may demand compensation when it is denied to him by governmental activity.
We recognize the most property in a metropolitan area would have a higher value if it were completely free of any noise, smog, or other undesirable features, provided the same conveniences were available. We are sure that if the metropolitan area had no airports, freeways, buses, trucks, trains, ambulances, and many other conveniences that are sources of noise, fumes, and whatnot, that property values would be substantially reduced. Property owners cannot -- and we are sure they do not expect to -- have the advantages created by conveniences and yet be paid for the undesirable effects created by the same conveniences unless those effects adversely affect their property so directly and so substantially that it is manifestly unfair to require them to sustain a measurable loss in market value which the property-owning public in general does not suffer. Thus, not every inconvenience, annoyance, or loss of peace and quiet caused by air flights will give rise to a cause of action in inverse condemnation against an airport operator.
The test, then, that we prescribe will give relief to any property owner who can show a direct and substantial invasion of his property rights of such a magnitude he is deprived of the practical enjoyment of the property and that such invasion results in a definite and measurable diminution of the market value of the property. [FN 4]
'The actor is liable in an action for damages for a non-trespassory invasion of another's interest in the private use and enenjoyment of land if,
'(a) the other has property rights and privileges in respect to the use or enjoyment interfered with; and
'(b) the invasion is substantial; and
'(c) the actor's conduct is a legal cause of the invasion; and
'(d) the invasion is either
(i) intentional and unreasonable; or
(ii) unintentional and otherwise actionable under the rules governing liability for negligent, reckless or ultrahazardous conduct.'
We recognize that with the test we have prescribed there may well be a dispute as to the property, if any, that is to be included in the inverse condemnation proceedings. Nonetheless, the court should make that determination initially based upon our interpretation of Thomsen and the market-value test here prescribed. [FN 5]
(1) The highest and best use to which the land may be put, as well as its present use, recognizing differences in the impact of sound and air pollution on areas suitable or zoned for residential, commercial, industrial, or recreational purposes.
(2) The topography of the land, including natural or artificial sound
barriers.
(3) The proximity to runways.
(4) The lateral and vertical distances from regular flight paths.
(5) The frequency of takeoffs and landings.
(6) The types of airplanes using the facilities.
(7) The flight patterns, holding patterns, and glide angles regularly followed.
(8) The location of the land relative to prevailing winds.
(9) Whether the duration of the easement contemplated is temporary or permanent.
The trial court also dismissed this action on the ground that MAC was not the proper defendant in that the airport was built largely with Federal funds in conformance with Federal specifications, and aircraft operations are largely controlled by Federal agencies. The United States Supreme Court dealt a similar argument a decisively fatal blow when it said:
Since this case was tried in the lower court and after it was first argued here, the United States Supreme Court decided Burbank v. Lockheed Air Terminal, Inc., 411 U.S. 624, 93 S.Ct. 1854, 36 L.Ed.2d 547 (1973). Based on that court's holding that congress has preempted state and local control over aircraft noise, a city ordinance prohibiting jet aircraft from taking off between 11 p.m. and 7 a.m. was held invalid. This decision does not reach the main issue before us. There is nothing in that decision indicating that Causby and Griggs were overruled. Mr. Justice Douglas wrote the majority opinion in Burbank and did not mention Causby or Griggs. Dissenting to the denial of certiorari in Chongris v. Corrigan, 409 U.S. 919, 93 S.Ct. 218, 34 L.Ed.2d 181 (1972), Mr. Justice Douglas, who authored Causby and Griggs, cited both cases with approval in these words:
'Appellants and the Solicitor General submit that this indicates that a municipality with jurisdiction over an airport has the power to impose a curfew on the airport, notwithstanding federal responsibility in the area. But, we are concerned here not with an ordinance imposed by the City of Burbank as 'proprietor' of the airport, but with the exercise of police power. While the Hollywood-Burbank Airport may be the only major airport which is privately owned, many airports are owned by one municipality yet physically located in another. For example, the principal airport serving Cincinnati is located in Kentucky. Thus, authority that a municipality may have as a landlord is not necessarily congruent with its police power. We do not consider here what limits if any apply to a municipality as a proprietor.' 411 U.S. 624, 635 note 14, 93 S.Ct. 1854, 1861, 36 L.Ed.2d 547, 555.
MAC denies that mandamus is a proper remedy in this action because the statute governing MAC gives it no clear legal duty to institute such proceedings, equitable considerations favor MAC, and no prior demand was made on MAC. The trial court, based on its interpretation of the governing statutes, agreed with this contention.
MAC is a public corporation under Minn.St. 360.101 to 360.144 and as such is invested with limited powers and responsibilities. As such, it has no inherent powers, but rather it only has 'such powers as are expressly conferred by statute or are implied as necessary in aid of those powers which are expressly conferred.' Village of Brooklyn Center v. Rippen, 255 Minn. 334, 336, 96 N.W.2d 585, 587 (1959). See, also, Kronschnabel v. City of St. Paul, 272 Minn. 256, 259, 137 N.W.2d 200, 202 (1965); and Mangold Midwest Co. v. Village of Richfield, 274 Minn. 347, 357, 143 N.W.2d 813, 820 (1966). Since a writ of mandamus may be issued only 'to compel the performance of an act which the law specially enjoins as a duty resulting from an office, trust, or station' (Minn.St. 586.01), we must look at the statutory and constitutional provisions governing MAC's actions.
MAC is given specific authority to acquire all necessary right, title, or interest in real or personal property for the development and maintenance of airports by Minn.St. 360.107, subd. 2. This power of acquisition is limited by the following language of that subdivision: 'Title to any such property acquired by condemnation or purchase shall be in fee simple, absolute, unqualified in any way * * *.' Petitioners in this case seek to compel MAC to acquire easements over their properties by condemnation, but this statutory language standing alone appears to deny MAC the authority to acquire such rights.
Petitioners, however, contend that the language of Minn.St. 360.074 is an exception to the limitation pointed out above because it gives 'municipalities,' including MAC (Minn.St. 360.061), the power 'to acquire such easements through or other interest in air spaces over land * * * as are necessary to effectuate the purposes of Laws 1945, Chapter 303.' This argument is not convincing in view of the fact that s 360.062 clearly states that the purpose of L.1945, c. 303, is to provide protection to the public from dangers and hazards of airport operation. It mentions nothing about discomfort and loss of property value due to noise and air pollution, as petitioners here allege they have suffered. The only other authority given to MAC to acquire less than fee simple interest is found in s 360.107, subds. 9 and 10, but those subdivisions clearly limit such acquisitions to situations where 'necessary to insure safe approaches to the landing areas' and 'to place, operate, and maintain suitable markings * * * for the safe operation of aircraft * * *.' Thus, it seems quite clear that MAC lacks specific statutory authority to acquire the easements involved in this case. This position is given further credence by the fact that the legislature recently provided MAC with precisely the powers found lacking here, but only in connection with a new major airport. L.1969, c. 1111, s 3, coded as Minn.St. 360.76.
Petitioners nonetheless argue with considerable persuasion that MAC was granted general powers that are broad enough to accord just compensation to property owners burdened by its activity. They point to the following language in Minn.St. 360.107, subd. 1, granting to MAC --
