The United States instituted thirteen actions, now consolidated, to condemn land in Hawaii. Honolulu Plantation Company had several claims for compensation, part of which have been paid. But Plantation claims “severance damages” because of loss of value of its properties as an operating concern by condemnation of property held in fee by third parties, resulting in an overcapacity of the sugar mill and refinery,, since it was claimed there was failure to obtain the customary supply of cane from such fields.

All the relevant evidence as to the claim of “severance damage,” which was heard by the learned Trial Judge, was produced by Plantation. The United States contended the claim was unsupported. The bulk of the testimony consisted of the opinions of experts as to valuation of the properties as a whole, including leases on other lands not taken, before and after condemnation. These values were ultimately based, generally speaking, on the invested capital necessary to produce refined sugar from certain areas, upon earnings of Plantation and its value as a going concern.

The record shows Plantation actually owned a comparatively small amount of land in fee upon which the structures enumerated above were in part placed. As the Trial Court says, this property consists of “scattered parcels which by good-fortune from time to time it has been able to buy in fee.” Long-term leases of lands owned by others made up the bulk of the holdings. Four hundred forty acres, so controlled for cane production, were condemned in these consolidated proceedings. The owners of these parcels had attempted by express clauses of the leases tq reserve to themselves all compensation in case of condemnation. Plantation claimed to have an understanding amounting to an engagement to lease covering five hundred ninety-five acres in addition, which were owned by the Damon Estate in fee and had been also condemned, but there was no formal written document covering this transaction.

The Trial Court awarded $440,175.00 damages inflicted upon the remaining properties by the condemnation of the four hundred forty acres. From this award, the United States appeals. The Court denied damages as to the five hundred ninety-five acres of Damon Estate, on the ground that Plantation had no legal interest therein. From this determination, Plantation appeals. This appeal will be first considered.

The proposition that Plantation, as a landowner, has a right to “severance damages ” where the United States condemns fee simple title to other lands vested in third persons, even though Plantation had no legally recognizable interest in the lands condemned, if true, is demonstrably paradoxical. Yet this must be the basis of Plantation’s appeal. There was no finding that the United States was taking the business. In fact, it was not. The Trial Judge found that the Damon Estate was the owner in fee simple of the five hundred ninety-five acres. The lease which Plantation held on this area expired in 1943. A renewal had never been executed. There had been understandings and negotiations, which indicated that Plantation could have cane from these fields for its mill so long as the positions remained constant. But the last correspondence in 1940, three years before the existing lease expired, looked toward the execution of a formal document. This gives Plantation no legal or equitable right in 1944. The inference is that the Damon Estate sensed the, creeping shadow of condemnation and desired to retain all the just compensation for itself, and deliberately did not give Plantation a property interest. The Trial Court found and, upon consideration, we hold that Plantation had no interest in these lands recognized by local law. The question is: Where the United States takes land owned by third parties in fee simple and in which Plantation has no legal interest, can “severance damages” be awarded because, owing to previous business arrangements, Plantation had expected to receive a supply of cane for its mill and refinery therefrom for a long period in the future?

The Fifth Amendment requires that, if property be taken, just compensation be paid. If then Plantation had no property in the Damon lands, it had no compensable interest. If compensation were not limited to owners of interests in property condemned, the sovereign, in taking property for public use, would be subjected to limitless claims of inconvenience, business loss and damage to prospects yet unborn.

By adulteration, the experts for Plantation evolved a clever amalgam of two proper doctrines as a basis for compensation. It is a rule that, in condemnation of part of a tract owned in fee simple, just compensation is the market value of the tract as a whole, before condemnation, less the market value of the portion which remains after the taking of the part. The rule applies exclusively to condemnation of fee simple title of a tract in one ownership. It is a rule that, if market value cannot be established by sales of comparable -property, consideration of other factors may be necessary to establish just compensation. But it must not be forgotten that the market value of real property is the criterion, and losses to a business are not for consideration.

The value of real and personal property and even movables is lumped by the experts before and after the taking. In this aggregation are included even the leases of Plantation upon lands not taken and in other ownership. By these and other devices, the experts succeeded in deducing a value to Plantation of $1,000.00 per acre for each acre held by lease or otherwise. By a fantastic process, involving a non sequitur, this figure per acre was testified to be the loss in value of the property of Plantation. It is, of course, clear that the real property held by Plantation was never appraised, either before or after the taking. Frankly, the witnesses say that the putative loss of $1,000.00 is arrived at by a capitalization of the earnings of Plantation, including its refinery, during years of most abnormal conditions in the island empire, while the price of sugar was supported by the Government. The formula thus applied produces its bizarre results because of the use of a factor comparable to infinity in mathematical calculations, of which the action is .unknown.

It can be thus demonstrated that these witnesses summoned by Plantation were stating loss to the business of growing cane, milling raw sugar and manufacturing refined -sugar. A minor chord vibrates through all the score: If it were able to ■buy “raws” of the competing monopoly, as it was able to do in war time, Plantation might have been able to make its ..accustomed profit, notwithstanding the takings.

The Trial Court says: “* * * usable land in Hawaii is scarce and tightly held by a comparatively few large corporation, trust, and estate owners who buy but rarely sell.”

In view of this statement, the only inference is that the fee properties of Plantation suffered no loss of value by the taking of surrounding lands, but were enhanced because of the increasing scarcity of such lands. These considerations constitute a conclusive refutation of the speculations of the “owners ” and experts, and land’s end!

The finding of the learned Trial Judge that there was no damage to the remaining properties of Plantation by condemnation of lands of the Damon Estate is then approved on two grounds: first, there was no less value proved as to the lands owned by Plantation in fee simple, and, second, as above noted, Plantation owned no interest whatsoever in realty of the Damon Estate. This holding is affirmed, and Plantation’s appeal is dismissed.

By an inconsistent line of reasoning, the Trial Judge allowed “severance damages” because of the condemnation of the four hundred forty acres. The same question stated above is primarily involved here also. Plantation had no more legal •interest in these tracts than in the Damon Estate. As to these individual parcels of land, fee title was vested respectively in other estates and individuals. Plantation had long leases on each parcel, and a clause of each lease divested any interest or estate of Plantation, upon condemnation. This condition subsequent destroyed any property interest of Plantation therein. The landowner reserved all compensation for the property. Therefore, this situation falls squarely under the principle followed by the Trial Court as to the Oahu Sugar Company lease, and upon this ground alone this award must be reversed.

The clause in the Oahu lease contains substantially the language emphasized in Note 6. If under the property law of Plawaii these words destroyed any compensable interest of Plantation in the realty condemned, as the Trial Court holds with regard to the Oahu lease, then the words have the same effect in the other leases. If Plantation owned no property in the realty taken, it was not entitled to just compensation by definition. Fifth Amendment. Since, by voluntary agreement upon condemnation, Plantation divested itself of any interest in property taken, the severance complained of was by its own act. To those consenting, there is no injury. The meaning of the contracting parties was made clear by emphatic words reserving all compensation in condemnation to the fee owner.

“Condemnation proceedings are in rem * * * and compensation is made for the value of the rights which are taken.” The lessee “had contracted away any rights that it might otherwise have had.” United States v. Petty Motor Co., 327 U.S. 372, 376 , 66 S.Ct. 596, 599 , 90 L.Ed. 729 .

The whole contention of Plantation as to these lands must be anchored to the reservation in the leases of claims for damage to its other lands. Since Plantation had no property interest in the lands condemned, this claim is for business losses. Since the right to recover such losses does not exist by law, certainly in the absence of the property right voluntarily destroyed by the clauses of the lease, as above pointed out, these contracting parties could not create by agreement between themselves such a right valid against the United States, as Judge Chesnut aptly shows in United States v. 8286 Sq. Ft. of Space in PacaPratt Bldg., D.C., 61 F.Supp. 737, 742 . The confusion of thought involved in the concept, “severance damages,” should not lead us to make any award where there is no property interest in the land condemned even if Plantation, with superficial cleverness, has attempted to distort the true meaning by the weasel wording of this proviso, agreed-upon between lessor and lessee, with the definite purpose of forcing the United States to pay each for the full value of the fee. Honolulu Plantation Company has heretofore attempted to collect money from the United States by the use of the same theory in another of its protean forms. This Court refused to be misled then as now. United States v. Honolulu Plantation Co., 9 Cir., 1903, 122 F. 581, 582, 583 . The prosecution of the claim must be referred to political bodies and not to courts, which should follow the law.

Although disposition has thus been made of the erroneous claims and theories of the experts, it behooves us to consider whether Plantation is entitled to compensation, without regard to the clauses of the respective leases. The representatives of the United States did not assist the learned Trial Judge by production of any relevant evidence, factual or opinion, as to this particular claim. Their attitude was simply one of negation.

It is advisable to establish our meridian before we proceed to survey the particular problems involved here. Plantation contends that the findings of value are conclusive. Findings of fact are conclusive on appellate courts, including values placed on real property in condemnation. Nowhere did the experts set a value on the realty owned in fee by Plantation. There .was no finding that the remainder of Plantation’s property suffered a loss in market value by virtue of the taking of the leaseholds. Nor could there be any. Opinion evidence is not evidence of fact. The trier of fact is not bound to follow the expert. Based upon unwarranted theorems of the experts, the Judge found “severance damage” to the properties as a whole. Where unwarranted theories of law or assumptions of fact guide the expert and are used as a basis for value by the Court, the evaluation will be set aside and the cause remanded for new findings.

The rule requiring" compensation for loss in market value of the remainder of the tract is applied strictly only where there is but a single parcel owned by one party in fee simple. An extension of the doctrine permitted the inclusion of another parcel in the same ownership if it lay contiguous to the principal tract. It is likewise perfectly true that the land cannot be valued alone without buildings or other structures which have been added thereto and which are a part of the real property. According to common law, these are as much a part of the soil as are the rocks, sand and other natural features. With some reluctance, the courts have held that the owner of one parcel in fee may be compensated for loss in market value thereof as a result of the taking of another parcel owned in fee by him, even if the latter is not contiguous, provided that, by actual and permanent use, a unitary purpose is served by both parcels. But strict proof of the loss in market value to the remaining parcel is obligatory. Where part of a tract in fee ownership is condemned, the loss in market value of the remainder cannot be augmented by consideration of the damage caused thereto by the taking or prospective use of lands held by third parties in fee simple as part of the same project. Nor can the fact that an enterprise upon one parcel depends upon other lands in fee ownership of third parties for supply of an essential material be used to connect the two for purposes of compensation. It is the estates in the separate parcels which must be connected. If, therefore, the fee owner of one tract holds a lesser tenure in the tract tafeen, there can be no additional compensation for this reason. The explanation is that the fee is the integer. The condemnor takes the particular ground. The whole structure of rights imposed upon this ground are destroyed. Compensation is paid by the parcel. Of course, a lease upon one parcel of land cannot be a part of the fee simple estate of another parcel.

A lease is a chattel, a contract right which carries with it the right of possession which goes back to the fee owner upon end of the term. The ownership of a fee of one parcel and a lease, upon another do not connect the estates in the two. From earliest times in federal condemnation, additional compensation has been refused where the owner of the fee of one tract had a lease upon another parcel held in fee by a third party, where the leasehold alone was taken.

The mirage conjured up by the experts and attorneys from the Baetjer case, supra, which gave fallacious promise of damages, is evanescent. It disappears and the familiar and long standing landmarks of condemnation law appear undistorted upon closer contemplation. There all the land involved was owned in fee by one individual. If all had been in one contiguous tract, the rule of deducting the market value of the residuary tract, after taking, from that of the entire tract, before taking, would have been applied. The trial judge there excluded evidence which tended to show integration of the scattered tracts in a unified whole by business use. The Appellate Court applied hornbook law and reversed. In sending the case back, it was clearly stated compensation could not be paid for losses of a business. The trial court then retried the case and found no loss beyond the value of the part taken was sustained by the part which remained. These principles applied are not only correct; these are classic. The decisions do not lay down a principle that abstraction of leasehold interest in other land constitutes a damage to a fee vested in another party. Again, no case has been cited which holds as Plantation contends. Since fixation of just compensation by evaluation before and after taking applies only to fee simple tracts, if applied in this case, the United States would pay Plantation the amount it would have paid if Plantation, had owned these tracts, covered by the leaseholds, in fee. But the United States has already paid for the fee to the owner, who reserved all compensation to himself. Therefore, the United States owes Plantation nothing on this theory.

The cause must then be remanded. The Trial Judge is acquainted with local conditions, and his finding as to loss of value of any property owned by Plantation will be accurate. We have found there is no such property interest involved in these leaseholds. The record is not sufficient for us to determine whether there are other property rights involved. We cannot tell whether consideration was given to loss in market value to the main fee properties by the cutting off of other fee parcels for which actual value has already been allowed. Nor can it be discovered whether any consideration has been given to a possible compensation for an interlocking network of easements for railroads, roads and irrigation systems. See United States v. Aho, D.C., 68 F.Supp. 358 ; United States v. Florea, D.C., 68 F.Supp. 367 . Of course, it may be that the municipal law of Hawaii does not establish such factors as interests in property. But these matters have not been presented. The learned Trial Judge is better acquainted with the customs of the community and can apply the doctrines of land law with precision. And it may be that such matters are already foreclosed by judgments which have heretofore become finalities. In any event, the cause will be remanded for further proceedings in accordance herewith.
