Smith, Justice.
These cases arise from actions taken by the State Department of [125]*125Transportation (DOT) and the City of Atlanta (the city) pursuant to our decision voiding a land transfer from the city to the DOT in Dept. of Transp. v. Brooks, 254 Ga. 303 (328 SE2d 705) (1985). In case no. 42499, the DOT seeks to overturn the DeKalb County Superior Court’s dismissal of a condemnation petition involving interests retained by the city in four parks in Atlanta, DeKalb County. In case nos. 42673, 42674, and 42675, the DOT, the city, and Arapaho Construction, Inc., seek to overturn the same court’s permanent injunction barring any further construction on any portion of the Presidential Parkway. We affirm case no. 42499. We affirm in part and reverse in part case nos. 42673, 42674, and 42675.
The Presidential Parkway is a proposed limited access highway designed to carry traffic between the downtown connector near its intersection with International Boulevard, and Ponce de Leon Avenue east of Moreland Avenue. Some of the recent, tangled history of the Parkway may be found in Brooks, supra. The Parkway, as planned, is meant to traverse portions of four parks owned by the city and located in DeKalb County: Candler Park, Shadyside Park, Goldsboro Park, and Dellwood Park.
Construction of the Parkway began in December 1984. In February 1985, after a hearing in Brooks, the Fulton County Superior Court issued an injunction barring some construction on the Parkway. Brooks was decided on April 23, 1985. In Brooks, we held that a deed transferring portions of these four parks from the city to the DOT was void because of “the very existence of the conflict of interest.” 254 Ga. at 317.
On May 20, 1985, the Atlanta City Council passed an ordinance, which was signed into law on June 3, 1985, authorizing a second transfer of portions of the four parks in controversy to the DOT. This ordinance, unlike the ordinance involved in Brooks, imposed a number of restrictions on the transfer. The text of the new deed conditioned the transfer upon the maintenance of a thirty-five mile per hour speed limit on the Parkway, a ban on “trucks and heavy vehicles” on the Parkway, and a bar against the widening of Ponce de Leon Avenue east of Moreland Avenue. The deed also contained a possibility of reverter to be triggered by any violation of these conditions.
On June 6, the DOT accepted the deed after objecting to the conditions and the possibility of reverter. That same day, Mayor Young and Commissioner Moreland of the DOT executed an agreement which stated that the DOT reserved the right to condemn certain property interests, primarily the possibility of reverter, which were reserved in the deed. On June 7, the DOT filed a petition in the DeKalb County Superior Court seeking to condemn the possibility of reverter and any other interest that the city might have retained in [126]*126the portions of the parks deeded to the DOT. The DOT paid $1.00 into the court as just and adequate compensation for the property interests condemned.
On June 10, appellees Davis, Schulman, Brady, and Ratel (the intervenors) moved to intervene. On July 1, the trial judge granted the motion to intervene and dismissed the condemnation petition. The trial court ruled that the description of the property interests to be condemned was insufficient, and that the DOT, in any event, could not condemn municipal property under the procedure it sought to use.
On July 2, Davis and Schulman, appellees in both cases here, filed suit to void the land transfer from the city to the DOT and to enjoin any further construction on the Parkway. The trial court granted a temporary restraining order against any further construction in the parks on July 12. On September 4, the trial court issued an order voiding the land transfer and a permanent injunction against any further construction on any portion of the Parkway.
1. Appellants contend that some issues raised by the intervenors should be barred by res judicata, and that the intervenors should be prohibited from pursuing this suit under the doctrine of laches.
a. Brooks, supra, involved the validity of the Atlanta City Council’s procedure in attempting to transfer land that it owned to the DOT, and the propriety of allowing a certain contractor to continue to work on the Parkway. We held that the contractor should be allowed to continue working on the Parkway, but that a conflict of interest on the part of the City Council President in presiding over council proceedings involving the transfer rendered the council’s actions in transferring the land void. Here, the intervenors claim that a second, separate transfer of the same property violates state law and municipal ordinances, and that the state may not condemn any interest reserved by the city in the subject property.
The DOT, thus, does not contend that questions relating to the condemnation issue and the procedure followed by the city in this transfer are barred by res judicata. The DOT primarily asserts that the appellees’ claims that the city does not have the authority to transfer the parklands, and that the dedication of the parks prevents their transfer, should be barred by res judicata. The question is thus reduced to whether the taxpayers’ previous successful attempt to prevent the earlier land transfer will act as a bar to their subsequent attempt to prevent a later land transfer of the same land on grounds that could have been, but were not in fact, used to justify the earlier bar on the first transfer.
An issue involving the same piece of land will not be barred when it arises out of a second transaction. The intervenors will not receive, under this holding, a “second shot” at the transaction involved in [127]*127Brooks. A finding of res judicata would not prevent multiple lawsuits here. The city and the DOT may have violated the same “right” of the intervenors in this case that they did in Brooks, but they did so in a different transaction. See Spence v. Erwin, 200 Ga. 672 (38 SE2d 394) (1946). The trial court correctly found that res judicata does not bar any of this action.
b. As the intervenors filed a timely motion to intervene in case no. 42499, and filed the second suit almost immediately after the condemnation petition was denied, we find no laches here.
2. The land in the four parks in question was expressly dedicated to the city for use as parklands. The city accepted the dedication. There were no reversionary clauses in the deeds of dedication. As the record in this action shows, the parks have not been abandoned by the city or the public.
a. “Where a municipality dedicates property to a public use, it inures to the benefit of all who are at the time, or may afterwards become, citizens of the municipality, such dedication being in the nature of an estoppel in pais; and where an attempt is made by the proprietor to revoke it by a sale of the land, the municipality may be enjoined by any person interested. Mayor &c. of Macon v. Franklin, 12 Ga. 239 (5, 6). Where a municipality dedicates property to a public use, it may be put to all customary uses within the definition of the use. Any use which is inconsistent, or which substantially and materially interferes, with the use of the property for the particular purpose for which it was dedicated, will constitute a misuser or diversion. Brown v. City of East Point, 148 Ga. 85 (3) (95 SE 962).” Norton v. City of Gainesville, 211 Ga. 387, 389 (86 SE2d 234) (1955).
Norton involved an attempted lease of parklands to a private interest. The court enjoined the lease. This court clearly indicated, in the passage quoted above, that the justification for the injunction of the lease rested in the fact that the lease would constitute a change in the nature of the use of the property, not in the fact that the lease involved a private party. In fact, no sale or conveyance was involved in Norton. The change in use of dedicated parklands was the central factor mitigating in favor of the injunction.
City Council of Augusta v. Newsome, 211 Ga. 899 (89 SE2d 485) (1955), and Harper v. City Council of Augusta, 212 Ga. 605 (94 SE2d 690) (1956), show the process mandated by this court in cases where a city wishes to alienate land which has been dedicated to it as a park, and which has not been abandoned. In Newsome, this court barred the City Council from selling a park to Sears and Roebuck on the grounds that the city did not have the power “ ‘to convey or sell land dedicated as a public park square, or common.’ ” 211 Ga. 899. The council, in turn, sought and received authorization to hold a referendum on the issue from the legislature. The citizens approved the sale [128]*128in the referendum, and this court approved the process in Harper. Harper and Newsome reify the theory that in this matter, which so closely affects the citizens of a municipality, and upon which they possess sufficient expertise to make a decision, representative democracy should be reduced to its most elemental form — the undiluted voice of the people.
b. In promulgating OCGA § 36-37-6.1 (Ga. Laws 1982, p. 2107, § 40), the legislature recognized the state law exemplified by Newsome. OCGA § 36-37-6.1 grants municipalities having a population greater than 300,000 the authority to “sell, exchange, or otherwise dispose of any real or personal property” including parks and property used for other recreational purposes except where “authorizing alienation . . . would be in derogation of rights, duties, and obligations imposed by prior deed ... or where such alienation would cause divesting of title to a park, playground, ... or other like property that has been dedicated to public use and not subsequently abandoned.” This statute gives large cities greater flexibility than OCGA § 36-37-6 does in dealing with their large holdings of municipal property, while preserving the interest of the public in recreational facilities so needed in urban areas. While this statute does not serve as an affirmative bar to the alienation of the parklands in question, it does incorporate the bar established in the conditions included in the deeds granting the parks to the city and the bar established by the dedication and the public’s acceptance of the parks in question.1
c. OCGA § 32-3-3 (b) states, “Any state agency, county, or municipality is authorized, for public road purposes, to enter into agreements with other state agencies, counties, or municipalities, with the federal government, and with private persons for the exchange of real property or interests therein for public road purposes.” The DOT, in its brief, “agrees [with the intervenors] that OCGA § 32-3-3 (b) could not authorize the City to transfer property which the City was otherwise prohibited by law from alienating.” As shown above, at this point in time, the city may not legally alienate the parklands in question. If, through legislation or referendum, the city acquires the right to alienate the land in question, OCGA § 32-3-3 (b) will, as the DOT contends, provide specific statutory authorization for a property exchange rather than an auction or a sealed bid procedure. See generally Beazley v. DeKalb County, 210 Ga. 41 (1) (77 SE2d 740) (1953); Kirkland v. Johnson, 209 Ga. 824 (76 SE2d 396) (1953).
d. The DOT contends that the trial court erred in finding the [129]*129land transfer here an ultra vires act by the City Council, and in ruling that certain municipal ordinances purportedly barring the transfer did not conflict with state law.
(i) “For [an] action to be considered ultra vires, it must appear that the action taken was beyond the scope of the powers that have been expressly or impliedly conferred on the municipality.” Newsome v. City of Union Point, 249 Ga. 434, 437 (291 SE2d 712) (1982). Here, the city did not have the power to alienate the parklands in question for the reasons stated above. For this reason, the City Council’s act in transferring the land was ultra vires and was properly enjoined as such.
We do not find, however, as the trial court did, that the transfer was an ultra vires act by reason of its conflict with certain city ordinances passed pursuant to a city charter provision. Atlanta City Charter § 6-403 requires the City Council to pass ordinances or resolutions providing for procedures to follow in “all sales and other dispositions of real and personal property by the City.” Failure to follow procedures adopted pursuant to this charter provision constitutes an “ ‘irregularity in the exercise of the granted powers,’ Georgia Granite R. Co. v. Miller, 144 Ga. 665 (2a) (87 SE 897) (1915),” Newsome, supra at 437, and thus does not constitute an ultra vires act. In addition, failure to provide procedures for an unauthorized action, such as the transfer of the land in question, could hardly be considered a violation of the city charter and an ultra vires act. The transfer was ultra vires due to the conflict with state law, rather than with the city charter or the city ordinances as the trial court ruled.
(ii) Atlanta Code of Ordinances § 5-5213 provides that the city may exchange “surplus real property” for other real property on a “ ‘square foot for square foot’ or ‘dollar value for value’ ” basis. Atlanta Code of Ordinances § 5-5224 states that the city must obtain “at least one (1) appraisal” to determine that in an exchange of property, the city receives equal value for value.
Code § 5-5213 does not, as the DOT contends, conflict with OCGA § 32-3-3 (b) which authorizes property exchanges between municipalities and state agencies. Code § 5-5213 simply does not provide a procedure for land transfers such as the one in question. We find no conflict.
As the failure of the City Council to comply with Code § 5-5224 would not result in an ultra vires action, see Newsome, supra, and a court of equity will not “restrain or control the discretionary powers of municipal officials” unless the officials act in a manner that is fraudulent, corrupt or ultra vires, Brooks, supra at 314, we find that .the trial court should not have based the voiding of the transfer on the city council’s failure to comply with Code § 5-5224. We thus need not reach the question of whether § 5-5224 conflicts with state law.
[130]*1303. Appellants contend that the trial court erred in ruling that an agency of the state, here the DOT, does not possess the power or the authority to condemn land in current public use owned by a municipal corporation.
a. Initially, we note that the trial court correctly ruled that the Constitutional provision regarding the power of eminent domain, Art. I, Sec. Ill, Par. I, only relates by its own terms to private property. That clause serves to ratify the limitation placed upon the state’s inherent right of eminent domain by the individual citizens’ right to own property. See Nichols on Eminent Domain, § 1.11 (3d ed.) No need for such a clause relating to municipal property exists, however, because municipal corporations, as creatures of the state do not possess any Constitutional right to own property, which creates the tension with the state’s right to eminent domain which, in turn, creates the need for Art. I, Sec. Ill, Par. I.
Cities exist by the grace of the state through special acts of the General Assembly. As a municipal corporation’s right even to own property may be limited in the special act creating that city, see Kirkland v. Johnson, 209 Ga., supra, the state certainly possesses the inherent power to limit those property rights through condemnation. A city is not, however, in total thrall to the General Assembly, much less a state agency such as the DOT, by nature of its creation. When the General Assembly creates a city, it limits the state’s power within the sphere of that municipality. It carves out an area in which the state may not, by fiat, operate in any manner in which it pleases.
The General Assembly may not, for example, pass laws that affect a municipal corporation in a manner “inconsistent with [the Georgia] Constitution, [or] repugnant to the Constitution of the United States.” Georgia Constitution, Art. Ill, Sec. VI, Par. I. This constitutional provision also states that the General Assembly “shall have the power to make all laws ... which it shall deem necessary and proper for the welfare of the state.” Just as the General Assembly is limited in its conduct relative to municipal corporations by Art. Ill, Sec. VI, Par. I, so is the DOT limited in its conduct relating to municipal corporations by laws passed by the General Assembly pursuant to Art. Ill, Sec. VI, Par. I.
Among the laws that the General Assembly has passed pursuant to Art. Ill, Sec. VI, Par. I, are the laws authorizing the DOT to condemn land. A reading of those statutes authorizing the DOT to condemn land will reveal the extent to which, and the manner in which, the legislature has allowed the DOT to manifest its power of eminent domain relative to a municipal corporation.
b. First, we look to Title 32 of the Georgia Code to examine the procedure that the legislature has set out exclusively for land acquisition for transportation purposes. OCGA § 32-2-2 (a) (8) grants the [131]*131DOT “the authority to exercise the right and power of eminent domain and to purchase, exchange, sell, lease, or otherwise acquire or dispose of any property or any rights or interests therein for public road purposes. . . subject to such express limitations as are provided by law.” This simply restates the proposition that the DOT’s power and authority to condemn property is subject to statutory limitations.2
Reading further in Title 32, OCGA § 32-3-1 (a) states, “Any property may be acquired in fee simple or in any lesser interests, including scenic easements, air space, and rights of access, by a state agency or a county or municipality through gift; devise, exchange, purchase, prescription, dedication, eminent domain, or any other manner provided by law for present or future public road or other transportation purposes.” OCGA § 32-3-2 then states, “All acquisition of property or interests for public road purposes shall proceed under the methods set out in this article and in Title 22.” OCGA § 32-3-3 authorizes the DOT, counties, and municipalities to acquire “any property” by “devise, exchange, prescription, or dedication.” In these statutes, the legislature declares that the DOT may acquire “any property” for road purposes only through the lawfully established procedures set out in Title 32 and in Title 22.3
The procedure that the DOT wishes to use in this case is introduced in OCGA § 32-3-4, which is entitled “Authority to bring condemnation proceedings.” (Emphasis supplied.) OCGA § 32-3-4 states, “Whenever any state agency, county, or municipality desires to take or damage private property ... for public road purposes . . . such state agency, county, or municipality . . . may file [a condemnation petition] in the [appropriate] superior court.” This represents the first time that the term “private property” appears in Title 32 regarding matters relating to condemnation.
OCGA § 22-1-3 states, “It is the province of the General Assembly to determine when the right of eminent domain may be exercised.” In Chestatee Pyrites Co. v. Cavenders Creek Gold Mining Co., 119 Ga. 354, 355 (46 SE 422) (1903), this court held, “[t]he right of eminent domain . . . lies dormant until the legislature sets it in motion. As the legislature can not in every case supervise the condemnation, it may confer the power upon agencies . . . [t]he power thus conferred is always to be strictly construed, and will not be permitted to be exercised except where it is affirmatively granted.” (Emphasis [132]*132supplied.) This court later, in State Hwy. Dept. v. Hatcher, 218 Ga. 299, 302 (127 SE2d 803) (1962), noted “the general rule in this country that statutes conferring the power of eminent domain must be strictly construed, and clear legislative authority must be shown to authorize the taking.” (Emphasis supplied.) Delegations of the authority to exercise the right of eminent domain, thus, must be strictly construed in Georgia.
In addition, we held in Dorsey v. Dept. of Transp., 248 Ga. 34, 37 (279 SE2d 707) (1981), that while the procedure for condemnation under OCGA § 32-3-2 et seq. does not violate due process, “the statute must be strictly conformed to by the condemning body.” In Frank v. City of Atlanta, 72 Ga. 428, 432 (2) (1884), we held, “[t]he taking or injuring of private property for the public benefit is the exercise of a high power, and all the conditions and limitations provided by law, under which it may be done, should be closely followed. Too much caution in this respect cannot be observed to prevent abuse and oppression.” Condemnation procedures thus must be strictly construed as well.
OCGA § 32-3-4 constitutes a delegation of authority to follow a specific condemnation procedure. As such, under the authority quoted above, we must construe the statute strictly against the condemning authority. We thus find that the term “private property” found in OCGA § 32-3-4 does not include property owned by a government or a governmental entity.
A number of other factors support this construction. First, Black’s Law Dictionary (5th ed.) defines “private” as “affecting or belonging to private individuals, as distinct from the public generally.” Our construction follows the plain meaning of “private property.”4 Next, OCGA § 32-3-4 marks the first appearance of the term “private property” in Title 32. After repeated references to “property,” or “any property,” we cannot ignore the legislature’s specific use of the adjective “private” for the first time. Finally, “private property” under this statute is subject to condemnation by “any state agency, county, or municipality.” We find no sense in a construction that finds a specific piece of property “private” when “any state agency” attempts to condemn it, and “public” when a “county or municipality” attempts to condemn it, as would be necessary under the DOT’s proposed construction.
The DOT cites United States v. 50 Acres of Land, 53 USLW 4001 (decided December 4, 1984), for the proposition that “private property” includes land owned by a municipal government for the [133]*133purposes of eminent domain. While that proposition seems plausible at first blush, we find that such a reading exalts the rule of the case above the reasoning behind the rule. As we are construing the same phrase in an entirely different context,5
6 we find the reasoning behind the ruling much more valuable than the black-letter law.
The United States Supreme Court, in 50 Acres, supra at 4003, held, “When the United States condemns a local public facility the loss to the public entity, to the persons served by it, and to local taxpayers may be no less acute than the loss in a taking of private property.” The court then held that “private property” for the purposes of the Takings Clause of the Fifth Amendment, included state and municipal property. The court, in effect, reasoned that the public interest in public property is as important as a private individual’s interest in private property for the purpose of construing language involved in eminent domain proceedings. Pursuant to this reasoning, the court construed the language in question against the condemning authority in a case where public interests were subject to condemnation proceedings. The substance, if not the form, of 50 Acres thus supports the use of strict construction against a condemning authority where public interests are the subject of eminent domain proceedings.
Following this construction, and the plain meaning of OCGA § 32-3-4, we find no specific authorization for the DOT to use the condemnation procedure set out in OCGA § 32-3-5 et seq. in an action against public, municipal property.6
c. The appellants cite Elberton Southern R. Co. v. State Hwy. Dept., 211 Ga. 838 (89 SE2d 645) (1955), and Southern R. Co. v. State Hwy. Dept., 219 Ga. 435 (134 SE2d 12) (1963) for the proposition that the DOT may condemn the land in question because the land in question is devoted to a public use. As the nature of the ownership of the land in question, not its use, controls this case, these cases are inapplicable here.
OCGA § 32-3-4 authorizes the taking of “private property.” Railroad property is generally owned by stockholders, not taxpayers. Such property may be devoted to public use but nevertheless remain private property. A railroad right of way is simply private property to which the public has a right of use. Even when put to a public use, [134]*134railroad property is primarily purchased and owned for the fundamental purpose of generating profit for the railroad.
Municipal land, on the other hand, is in all respects public property. While OCGA § 32-3-4 might authorize the taking of private property put to a public use, public property, as seen above, is an entirely different species. Since railroad property is private property, not public property, we find Elberton Southern, supra, and Southern Railway, supra, to be inapplicable.
These two cases, in addition, were based upon 1933 Code of Ga. § 95-1724, which stated, “The State Highway Board, acting for and in behalf of the State, is hereby authorized and empowered to exercise the right of eminent domain in the condemnation of rights of way and property thereon for the use of the system of State highways . . . .” We need not attempt to interpret this statute because: a) The language of the statute differs considerably from the language of the statutes involved in this case; b) The cases arising from this statute, as stated above, do not relate to the fact situation in the present case, and, most importantly; c) Code § 95-1724 was repealed along with all of former Ga. Code Ann. Title 95 by Ga. L. 1973, p. 947. Elberton Southern Railway, supra, Southern Railway, supra, and Code § 95-1724 do not relate to, much less control, this case.
d. OCGA § 22-2-102, which provides for condemnation proceedings before a special master, and OCGA § 22-2-130, which provides authority for condemnation proceedings before the superior court also state that they are available “for the taking or damaging of private property” (OCGA § 22-2-102), or where the condemnor “desires to take or damage private property.” (OCGA § 22-2-130.) We find our construction of OCGA § 32-3-4 applicable to these statutes, and thus find that the DOT may not condemn municipal property under OCGA § 22-2-102 or OCGA § 22-2-130.
e. In Young v. McKenzie, 3 Ga. 31 (1847), this court addressed an act of the legislature which incorporated a company for bridge building, and which provided the company with the authority to condemn property and with a procedure by which it might condemn property if necessary. The court held that the act was an expression by the state of the power of eminent domain, and that the right to delegate such power rested in the legislature. The court held the act constitutional.
The 1863 Code of Georgia contained three general statutes dealing with eminent domain. Code § 2201 (now OCGA § 22-1-2) defined the power of eminent domain, and also stated that “in time of peace the General Assembly may authorize the appropriation [any part of the territory of the state] to public purposes.” Code § 2202 (now OCGA § 22-1-2) codified the ruling in Young, supra, that the power to delegate the authority to condemn property rested in the General Assembly. Code § 2203 (now OCGA § 22-1-4) stated that the General [135]*135Assembly could “exercise the right of eminent domain” through state officers, corporations, or through “means of individual enterprise.” Code § 2204 (now OCGA § 22-1-5) stated that compensation was to be paid the condemnee before the property was taken except in extreme emergencies. The legislature did not set out any specific procedure for condemnors to follow in the 1863 Code.
In 1894, the legislature enacted a law entitled “Condemnation of Private Property” (Ga. L. 1894, p. 94) and which subsequently appeared in the 1895 Code of Georgia § 4657 et seq. Code § 4657, the initial section in the law, stated, “All corporations or persons authorized to take or damage private property for public purposes shall proceed as herein set forth.” This statute now appears as OCGA § 22-1-8, except that “corporations” has been deleted, and “as herein set forth” now reads “as set forth in this title.” Code § 4660 stated, “The corporation or person seeking to condemn property for public purposes shall serve a notice upon the owner of the property . . .” This statute, with “All corporations or persons” changed to “Any person,” now appears at OCGA § 22-2-20.
“Property” in OCGA § 22-2-20, thus, was originally limited to “private property” by the title of the law which included the original statute, and by original code § 4657. (OCGA § 22-1-8.) As the inter-venors point out, these statutes — the general statutes and the procedural ones — remained separately grouped until the latest revision of the code in 1982. Now, former code § 4657 (OCGA § 22-1-8) has been removed from the chapter authorizing the procedure before assessors to the general chapter, Title 22, Chapter 1. Former code § 4660 (OCGA § 22-2-20) remained in the chapter authorizing the procedure.
This change in position of these two code sections did not change their relationship. First, the plain meaning of OCGA § 22-1-8 authorizes only condemnation of private property pursuant to Title 22. Next, “[e]xcept as otherwise provided by [the 1983 code], the enactment of [the 1983 code] is not intended to alter the substantive law in existence on the effective date of this code.” OCGA § 1-1-2. “Property” is still limited to “private property” for the purposes of OCGA § 22-2-20.
f. While the DOT, as an agency of the state, may upon authorization serve as a conduit for the state’s inherent power to exercise eminent domain over municipal property, the legislature has not clearly given the DOT the authority or the procedure by which the DOT might condemn municipal land. If our interpretation of the original legislative intent or our construction of the statutes in question differ from the intent of the present legislature, that body, as the law-making branch of the government, may enact such laws as it sees fit to effectuate that intent.
4. The DOT contends that the city may not withdraw its consent [136]*136for construction of the Parkway.
OCGA § 32-6-111 (a) states that limited access roads may be planned, built, and maintained in municipalities, “provided, further, that within such municipalities such authorization shall be subject to such municipal consent as may be provided by law.” The statute authorizes “the department [of transportation] or a county or a municipality in this state [to act] alone or in, cooperation with each other. . .” to follow through with such a road. Here, the “Campbell Resolution” and the ordinance authorizing the land transfer constitute “municipal consent” as well as “cooperation” between the city and the DOT. The DOT’s reliance upon such consent, in moving forward with construction on the Parkway, estops the city from revoking its consent to the construction of the Parkway. As for regulation and maintenance of the Parkway, the DOT and the city may “cooperate” and otherwise act as they see fit pursuant to this opinion and any other relevant state law.
5. The DOT contends that the conditions upon which the city based its possibility of reverter are void, since they purport to restrict the state’s power of eminent domain. They argue that the conditions are thus contrary to public policy, and as a result are void under OCGA § 44-6-43.
As seen above, the state possesses the power of eminent domain over the city’s property. We do not, however, read the conditions as attempts to limit the state’s power of eminent domain. Upon authorization, in fact, the DOT may condemn municipal property interests, as was discussed above. Since the possibility of reverter gives meaning to the conditions, we find no conflict between the conditions and the DOT’s power of eminent domain. In any event, our vacation of the land transfer renders the question moot.
6. The trial court granted a permanent injunction against any further construction on the Parkway largely on the basis of its conclusion that, as a constitutional matter, the DOT could never condemn any of the city’s interest in the parklands.
We find no such constitutional barrier. The General Assembly may certainly provide the DOT with the authority and the procedure to condemn any municipal property, or this municipal property alone. The General Assembly may also grant the city the authority to hold a referendum or follow any other procedure the General Assembly finds proper, to effectuate the land swap. Keeping these guidelines in mind, we lift the trial court’s injunction of construction on land not included in the parklands in controversy. The DOT, thus, may proceed as it desires at its peril, as the equities will be balanced in the future as of the date of the trial court’s initial injunction in this case.
7. Under OCGA § 32-3-17, taxpayers possess the right to intervene in condemnation actions against land owned by the entity to [137]*137which they pay their taxes. In other words, the public possesses “an interest” in public property.
8. We do not reach the issue of the DOT’s description of the possibility of reverter in its condemnation petition, since our holding relative to the DOT’s authority under OCGA § 32-3-4 will support the trial court’s dismissal of the condemnation petition.
9. We need not reach the DOT’s complaint that it was denied the right to full discovery by the trial court, as our holding on the res judicata effect of previous suits involving the Parkway did not rest upon lack of identity of the parties.
10. In addition, we need not determine the sufficiency or insufficiency of the description of the property interest condemned by the DOT, as we have decided that the condemnation procedure that the DOT operated under was not available to the DOT.

All the Justices concur, except Hill, C. J., Marshall, P. J., and Weltner, J., who dissent.
