Appellant was and is the owner of a tract of land in Arizona, a portion of which it leased to the respondent in May of 1943. The lease remained in effect until October of 1952. The instrument ag originally proposed by the government was on a form provided by it, which form as printed contained a provision f0 the effect that the lessee “if required by the lessor, shall * * * restore the premises to the same conditions as that existing at the time of entering on the game. * * * ” in the lease as signed, however, this provision was deleted by tbe parties and a provision designated «par. 12>” reading as follows, was inserted •

„A survey and inSpection 0f the conditiong of the within„de. scribed premises has been made and reveals the property to be unimproved desert land, on which there are no physical improvements, and the lessor agrees to the foregoing statement and hereby relieves the Government of any and all restoration responsibility resulting from the use of the subject lands by the Armed Forces.”

During itg possession the government uged ^ ¡and ag a miljtary ^ con. gtructing thereon buMings and other structureg having eoncrete foundations. Qn ^ expiration of the leage it re_ moved ^ buildingg but did not remove or disturb the foundations. It is agreed ^ lhe cogt of removal of the latter would amount to gome ?17 5001 This suit is for the recovery of damages for failure to remove the obstructions.

The suit as originally filed failed to allege a ground of federal jurisdiction, and the trial court dismissed the com*882plaint with leave to amend. As amended some three years after the termination of the lease it imported nothing new except as regards an allegation that the respondent “wrongfully and tortiously” refused to remove the foundations.

The trial court on hearing the matter made findings on the basis of which it concluded that the contract \ of lease specifically relieved the_ government of any duty to remove buildings or other structures from the premises, and that the plaintiff take nothing by its amended complaint. Judgment was accordingly entered for the government.

The court’s disposition of the case was clearly correct, and its judgment is affirmed.

(concurring)

_ in addition to paragraph 12 of the lease, quoted in the opinion of the court, the lease contained a paragraph 8 which reads as

"The GOvernment shall have the right, during the existence of this * ’ * , lease, to make a-terations, attach fixtures, and erect additions, structures, or signs, in or upon the premises hereby leased (provided such alterations, additions, structures, or , , ’ . , . , signs shall not be detrimental to or . ... , , inconsistent with the rights granted , ,, , , , to other tenants on the property or in the building in which said premises are located); which fixtures, additions, or structures so placed in or upon or attached to the said premises shall be and remain the property of the Government and may be removed therefrom by the Government prior to the termination of this lease. * * * ”

The nub of appellant’s contention is that, under paragraph 8, the Government was authorized to remove all of a particular fixture, addition, or structure, including the concrete foundations thereof, but that it could not remove a part of any such fixture, addition, or structure, leaving portions which were unusable and expensive to remove. Appellant poses the question: “If the Ap-pellee had removed the roof from each of the buildings, wouldn’t the Court be justified in saying that it must pay for the removal of the remaining part?” Acknowledging that there was no express covenant to complete the removal of any structures, • appellant argues that such a covenant is to be implied,

The leage in question gave the Gov_ ernment the right to remove improvements at the expiration of the lease, but not the duty to do g0_ There ig no express covenant requiring the Government to restore the premises to the same condition as that existing at the beginning of the term. Under these circumstances, there is no implied covenant of the kind suggested by appellant. n.w. Z age occasioned by reason of partial removal of improvements, unless there was negligence in accomplishing such removal.

The Iefal principle just stated finds support m a great many cases. See, „ , ^ i • for example, Duvanel v. Sinclair Refining Co., 170 Kan. 483, 227 P.2d 88, 23 A.L.R.2d 649; Fox v. Cities Service Oil Co., 201 Okl. 17, 200 P.2d 398; Arkansas Fuel Oil Co., v. Connellee, Tex.Civ.App., 39 S.W.2d 99. In each of the cited , , . . , cases, the tenant removed improvements, . . . . , ,. , ,, , leaving concrete foundations and blocks,

No negligence incident to the removal of the structures and the leaving of the concrete foundations was charged by appellant, or found by the court, The Government had good reason for removing the one and leaving the other, The structures could be used elsewhere and the foundations could not. The lack of reasonableness and the indications of wantonness, which are suggested by apPellant’s “horrible example” of removius^ roo^s’ *s absent here,

Under the rule referred to above, the Government would be free of liability even in the absence of a covenant expressly relieving it of responsibility for restoring the premises. But here there is such a covenant — paragraph 12 *883of the lease. A covenant to restore could not possibly be implied in the face of this express covenant to the contrary, As stated in Brimmer v. Union Oil Co. of California, 10 Cir., 81 F.2d 437, 440, 105 A.L.R. 454, “an express covenant upon a given subject deliberately entered into without fraud or mutual mistake, excludes the possibility of an implied covenant of a different or contradictory nature.”
