In this inverse condemnation action, Western Fertilizer and Cordage Company, Inc. (Western), brought suit against the City of Alliance (City), seeking-damages resulting from utility easements and water, sewer, and street improvements made by the City on property purchased by Western at a foreclosure sale. The trial court sustained the City’s motion for summary judgment, and the Nebraska Court of Appeals affirmed. Western petitioned for further review pursuant to Neb. Rev. Stat. § 24-1107 (Cum. Supp. 1992). We reverse the judgment of the Court of Appeals.
FACTUAL BACKGROUND
Western was the mortgagee of 79.8 acres of land sold to BRG, Inc., in 1976 for $239,400. BRG, which planned to develop the land for residential use, authorized the City to improve the property. After BRG defaulted on the mortgage, Western filed suit against BRG and the City to foreclose on the mortgage and to determine the validity and priority of certain liens and assessments claimed by the City. The City cross-petitioned, claiming lien assessments totaling over $274,000. In an appeal from that action, this court determined that “Western did not sign or consent to the dedications, and, consequently, the assessments for improvements upon the land mortgaged to Western are not valid as against Western’s mortgage, and are inferior thereto.”
Western Fertilizer
v.
BRG,
The following is a chronology of events in the present action:
May 19, 1976 — BRG purchased the property from Western for development purposes, with the final payment due October 1,1977.
April 1977 — The City passed two ordinances approving the plat of Homestead First Addition which contained a dedication of the streets, alleys, and public grounds therein to the use and *97 benefit of the public.
August 31, 1977 — Western’s president, Gordon Keeley, on behalf of Western, signed one dedication for part of the property.
September 29, 1977 — Restrictive covenants, including certain utility easements, were established by Western and BRG and signed by Keeley.
October 1977 — BRG gave Western a promissory note secured by a mortgage on the property in question. On the same day the mortgage was executed (October 26), the parties entered into an amended sales agreement which reflected changes (partial platting) with respect to development of the real estate.
November 1978 to October 1981 — BRG signed several more dedications during this time period; Western’s secretary-treasurer, Max Garwood, without authority to do so, signed the same dedications on behalf of Western. In addition, the City passed several ordinances approving plats and establishing sewer, water, and street improvement districts in the property.
Early 1983 — After Garwood left Western, Keeley learned that Garwood had signed the additional dedications.
August 1983 — Keeley complained to the City about the unauthorized dedications and informed the City that Western did not join in or consent to those dedications signed by Garwood. He also advised the City that BRG was in default on its debt to Western and that Western might be forced to foreclose its mortgage on BRG’s land.
May 1985 — Western initiated foreclosure proceedings. See Western I.
June 17,1988 — Issuance of decision and opinion in Western I.
October 1988 — Western acquired the property at a foreclosure sale and received a sheriff’s deed for the land.
August 23, 1990 — Western filed its inverse condemnation action against the City.
In its petition in the inverse condemnation action, Western alleged that the City “had taken and damaged for public use all or parts of the lands” in question without just compensation and that in the event the court found that the City had not taken *98 all of the property in question, Western had nonetheless suffered incidental and consequential damages to the land not taken.
Both parties moved for summary judgment. In its motion, the City asserted that (1) the statute of limitations barred Western’s action; (2) Western was estopped from claiming that the City had taken Western’s property because Western had taken title to the property by lot and block numbers; (3) this court, in Western I, had held that the easements acquired by the City were valid but subordinate to Western’s mortgage; (4) Western did not acquire a cause of action for condemnation damages when it purchased the property at the foreclosure sale; and (5) Western was estopped from denying the easements it did not specifically approve because it became bound to the plan of development when it accepted Homestead Addition and Homestead First Addition.
The district court granted summary judgment to the City, ruling that “[t]he fact that the defendant’s assessment and lien are void against the priority of the plaintiff’s lien does not mean they have ‘taken’ private property of the plaintiff without just compensation.” The court found that Western had purchased the property in question with “actual notice of the defendant’s interest in the land” and, thus, its interest could be no greater than that of BRG, which had authorized the City’s claims to the property. Furthermore, the court found that “the defendant’s easements and appropriations are open, visible, recorded of public record and make plaintiff’s claimed ownership a servient estate to the defendant government’s exercise of dominion over, appropriation, and interest in the real estate.
Kimco Addition v. Lower Platte South N.R.D.,
Western appealed to the Nebraska Court of Appeals, which affirmed the trial court’s decision in
Western Fertilizer
v.
City of Alliance,
On the question of inverse condemnation, the Court of Appeals stated:
The record shows that BRG gave permission for the City to make improvements on the property in question. BRG would not have had an action against the City for inverse condemnation because it gave the City permission to perform the improvements. Similarly, Western, as owner in lieu of BRG, does not have an action against the City for inverse condemnation.
The judgment of the Nebraska Supreme Court in [Western I\ established the priority of the interests as between Western and the City. Western, as mortgagee, had a security interest in the property and a right to protect that interest, which it did in the foreclosure action. The City’s failure to acquire permission from Western, as mortgagee, for the improvements was not a “taking” of Western’s interest in the property because Western did not have title or possession of the property at the time the improvements were consented to and made. Therefore, Western, as mortgagee, did not have rights against the City for inverse condemnation.
Western petitioned this court for further review pursuant to § 24-1107, asserting that (1) the Court of Appeals had significantly changed Nebraska law that a purchaser at a foreclosure sale acquires every right and interest in the property of all the parties to the action and (2) the Court of Appeals’ holding that the purchaser at a foreclosure sale acquires title subject to the rights of a junior lienholder who was a party to the foreclosure proceeding is contrary to both Neb. Rev. Stat. § 25-1533 (Reissue 1989) and prevailing case law.
Article I, § 21, of the Nebraska Constitution states, “The property of no person shall be taken or damaged for public use without just compensation therefor.” Article I, § 21, of the Nebraska Constitution is self-executing, and therefore, a cause of action may be brought directly under that section. A litigant must simply “ ‘allege and prove facts constituting a cause of action’ under the constitutional language.”
Dishman
v.
*100
Nebraska Pub. Power Dist.,
WESTERNI
In its answer to Western’s petition, the City set forth a counterclaim in which it asked the court to set aside the judgment in the foreclosure action which is the subject of Western I. The City alleged that although Keeley, Western’s president, testified that he was never asked to sign, nor did he sign, any plat or dedication on behalf of Western other than the plat signed on August 31, 1977, he did, in fact, sign on September 29, 1977, a document entitled “Restrictive Covenants,” which was a dedication of street and utility easements upon which the City relied. The City argues that this nondisclosure was material to the decision in Western I and that, therefore, that judgment should be set aside.
The document to which the City refers provides that anyone taking title or possession of property within Homestead First Addition waives any claim against Western or BRG arising out of construction, maintenance, repair, renewal, replacement, or operation of utility easements. It was signed by Keeley before the mortgage was executed, was offered into evidence in the foreclosure action, and presumably was considered by the court. Thus, according to Western, the issue of its lack of approval of the dedications is res judicata.
The doctrine of res judicata
is based on the principle that a final judgment on the merits by a court of competent jurisdiction is conclusive upon the parties in any later litigation involving the same cause of action____
*101 Res judicata is founded on a policy favoring termination of an action by preclusion or prevention of subsequent litigation on the same cause.

Of course, a court may modify or vacate a judgment pursuant to Neb. Rev. Stat. § 25-2001 (Reissue 1989) or its equitable powers. Although a court’s authority to vacate or modify a judgment under § 25-2001 is not exclusive,
Joyce
v.
Joyce, 229
Neb. 831,
The question of whether Keeley approved the dedications to the City was central to our decision in Western I. Therefore, under the doctrine of res judicata, we are bound by the factual findings in Western I, as discussed below.
*102 THE FORECLOSURE SALE FOR WESTERN’S MORTGAGE
In Western I, we affirmed the district court’s order foreclosing Western’s mortgage and ordering the sale of the real estate. The City claimed its lien for unpaid assessments was superior to Western’s mortgage. We disagreed, noting that
“ ‘[fundamental to the law of real property is the rule that one may not convey or alienate a greater interest in land than he owns, and, consistently with this axiomatic principle, it is firmly established that a mortgagor cannot, without the consent of the mortgagee, make a dedication of the mortgaged premises so as to adversely affect the interest of the mortgagee.’ [Citations omitted.]”
Western argues that because the City was a party to the foreclosure action, Western acquired all the rights and interests of the City when Western purchased the property at the foreclosure sale.
The purpose of a foreclosure action is to satisfy, out of the proceeds of a sale of the estate in the mortgaged property as it stood at the time the mortgage was executed, the claim of the holder of the obligation when there is a default in the performance of the act it is given to secure.
4 American Law of Property § 16.186 at 446-47 (A. James Casner ed. 1952). As the result of a foreclosure sale of real estate given as security by the mortgagor, the rights of redemption of the mortgagor and junior lienholders who are joined in the action are extinguished, and upon confirmation of the sale, the purchaser obtains title to the “ ‘entire interest and estate of mortgagor and mortgagee as it existed at the date of the mortgage.’ ”
Id.
at § 16.195 at 469 (quoting
Rector, etc., of Christ P. E. Church v. Mack et al.,
Furthermore, in
Metropolitan Life Ins. Co.
v.
SID No. 222, supra,
we held that “in the absence of an estoppel, or the consent of the mortgagee to a dedication, a foreclosure sale revokes and nullifies an attempted dedication by a mortgagor.”
However, the City points out that this court has also held that the purchaser of real property at a judicial sale buys at his peril,
Hitchcock County v. Cole,
Moreover, the City argues that according to § 25-1533, a deed obtained at a judicial sale
shall be sufficient evidence of the legality of such sale and the proceedings therein until the contrary be proved, and shall vest in the purchaser as good and as perfect an estate in the premises therein mentioned as was vested in the party at or after the time when such lands and tenements became liable to the satisfaction of the judgment.
According to the City’s interpretation of § 25-1533, Western, as purchaser at a judicial sale, could obtain only that estate which was vested in BRG at or after the time of the foreclosure action. Although the language of § 25-1533 (the purchaser at a judicial sale takes only the interest that the owner had in the land) might appear to conflict with Nebraska case law (the purchaser at a foreclosure sale takes every right and interest of all parties to the foreclosure action), the language of § 25-1533 contemplates that only one party is “liable to the satisfaction of the judgment.” In a foreclosure action in which junior lienholders are joined in the action against the mortgagor, they, in a sense, share in liability for the satisfaction of the judgment by being stripped of their interest in the property foreclosed upon. Thus, the rule providing that when a senior mortgagee purchases the mortgaged real estate at a foreclosure sale, the confirmed purchase and sheriff’s deed extinguish the rights of junior lienholders who were parties to the action, does not conflict with § 25-1533. See
Valentine
v.
Portland Timber,
Thus, in this case, the City’s junior lien was extinguished when Western purchased the property at the foreclosure sale for less than the amount owed on its mortgage, see,
Northwestern Mut. Life Ins. Co. v. Nebraska Land Corp.,
TAKING WESTERN’S PROPERTY
Because we have concluded that Western should have received the entire estate as described in the mortgage documents, we must determine whether, in the absence of that occurring, Western’s property has been taken. The district court held that “[t]he fact that the defendant’s assessment and lien are void against the priority of the plaintiff’s lien does not mean they have ‘taken’ private property of the plaintiff without just compensation,” because any failure to secure Western’s consent to the dedications was paid for by the City’s loss of its claimed lien in the foreclosure action. The court also found that Western had purchased the property in question with “actual notice of the defendant’s interest in the land,” and thus, Western’s interest could be no greater than that of BRG, which
*106
had authorized the City’s claims to the property. The court held that Western’s claimed ownership was servient to the City’s easements and appropriations. However,
Kimco Addition v. Lower Platte South N.R.D.,
Relying in large part on
Peterborough Savings Bank
v.
Pierce,
The Court of Appeals clearly erred in concluding that no taking could have occurred when Western was mortgagee “because Western did not have title or possession of the property at the time the improvements were consented to and made.”
Thus, it does not matter that Western had neither title nor possession of the property at the time the alleged taking occurred if its interest in the property was adversely affected by the City’s actions. Whether Western’s interest in the property was affected depends upon whether the property described by the sheriff’s deed received by Western at the foreclosure sale differs from the property described in the mortgage which Western obtained from BRG. If the property as described by the sheriff’s deed differs from the property described in the mortgage, then the property was taken prior to Western’s purchase of the land at the foreclosure sale, and the City must pay compensation, unless, as the City asserts, the statute of limitations bars this action.
STATUTE OF LIMITATIONS
Neither the district court nor the Court of Appeals addressed the City’s assertion that the statute of limitations barred Western’s action. The City acquired its interest in the property as a result of BRG’s dedications, which granted the City easements for a variety of purposes. The City then passed ordinances levying assessments on the property. Those ordinances were matters of public record, and notices thereof were published in The Alliance Daily Times-Herald on various dates between November 1978 and October 1981. The City argues that Western’s cause of action accrued when those dedications were made and the ordinances passed and that, therefore, this action is barred by the statute of limitations. Furthermore, the City asserts that because extensive development had already occurred in 1979-80, Western had *108 notice of any infringement of its interest in the property by 1980. Western argues that the statute of limitations did not begin to run until it received the sheriff’s deed in October 1988. Western asserts that until that time, the City’s use of the property was permissive.
The statute of limitations in an inverse condemnation proceeding is 10 years. Neb. Rev. Stat. § 25-202 (Reissue 1989). See, also,
Krambeck
v.
City of Gretna,
Inverse condemnation is analogous to an action by a private landowner against another private individual or entity to recover the title to or possession of property. While the property owner cannot compel the return of the property taken, because of the eminent domain power of the condemner, he has a constitutional right, as a substitute, to just compensation for what was taken.
Krambeck v. City of Gretna,
In
Simacek v. York County Rural P.P. Dist.,
Similarly, in the present case, at the time BRG made the dedications and the City passed the ordinances, BRG was the record owner of the property and was in possession of the land., Thus, Western contends that as in
Simacek,
the City’s use of the property was permissive until Western acquired the property at the sheriff’s sale. However, our decision in
Simacek
was based on the premise that the power district’s use of the land was “ ‘in complete subservience to the exclusive right of the “Railway Company” prior to the abandonment of the railroad____’ ”
The Iowa Supreme Court addressed a similar situation in
Scott
v.
City of Sioux City,
Similarly, BRG’s dedications and passage of the city ordinances had an immediate impact on Western’s interest in the property. Western seems to have recognized this, because in August 1983, after Western’s president, Keeley, learned that unauthorized dedications had been made, he complained to the City about those dedications and informed the City that Western did not join in or consent to those dedications. Therefore, although the City’s interest in the property was obtained with BRG’s approval, it was never permissive with respect to Western.
Furthermore, Western had notice of the City’s claim to the land well before it obtained the land at the sheriff’s sale. In
Polanski
v.
Eagle Point,
Neb. Rev. Stat. § 17-416 (Reissue 1991) provides, in pertinent part, that when a plat is properly “executed and acknowledged, the plat shall be filed for record and recorded in the office of the register of deeds and county assessor of the proper county.” Neb. Rev. Stat. § 17-417 (Reissue 1991) provides in part that “[t]he acknowledgment and recording of such plat is equivalent to a deed in fee simple of such portion of the premises platted as is on such plat set apart for streets or other public use.” Because Nebraska law provides that a properly executed and recorded plat is equivalent to a deed, under the reasoning in Polanski v. Eagle Point, Western received notice of the City’s claim when the plats were recorded, and not when construction of the improvements began. The record in this case is silent, however, as to if and when the plats were recorded. Furthermore, the City’s ordinances, if validly passed, were matters of public record with notice thereof published in The Alliance Daily Times-Herald and provided Western with constructive, if not actual, knowledge of the City’s interest in the property by 1981.
However, the fact that the City claimed an interest in the property may not be sufficient to start the statutory period running if the City did not put the property to public use. Neb. Rev. Stat. § 76-714 (Reissue 1990) provides:
The interest in the property acquired by the condemner shall be such title, easement, right-of-way, or use as is expressly specified in or necessarily contemplated by the law granting to the condemner the right to exercise the power of eminent domain. The condemner shall not dispossess the condemnee until the condemner is ready to devote the property to a public use, and such title or interest as the condemner seeks to acquire shall not be complete until the property is put to the public use for which taken.
(Emphasis supplied.) Thus, under § 76-714, the City could not complete its interest until the property was put to the public use for which it was taken. This occurred when the City exercised
*112
dominion over or appropriated an interest in the property. See
Rose
v.
City of Lincoln,
In
Village of Maxwell
v.
Booth,
In the present case, the City passed ordinances regarding the dedications, apparently published those ordinances, and began construction of the improvements pursuant to the ordinances. However, the record is silent as to when actual construction began or was completed. Thus, we are unable to determine when the City exercised physical control over the property. Moreover, the various dedications and ordinances apply to different parts of the property in question and provide the City with easements for a variety of purposes. Because some of the dedications and ordinances occurred more than 10 years before this action was filed, even if passage of the ordinances established the City’s dominion over the land, the statute of limitations has run on some portions of this action. However, some of the later dedications and ordinances may also have *113 effected a taking and may not be time-barred. Thus, the date of any taking is a factual question which should have been determined by the trial court.
CONCLUSION
The Court of Appeals erroneously held that no taking can occur if the mortgagee has neither title nor possession of the property at the time the mortgaged property is put to public use. In addition, because the question of when the appropriations actually occurred is a genuine issue of material fact not determined by the trial court, summary judgment was inappropriate. Therefore, we reverse the decision of the Nebraska Court of Appeals and remand this cause to the Court of Appeals with directions to reverse the district court’s summary judgment for the City and to remand this cause to the district court for further proceedings.
Reversed and remanded with directions.
