1. Code §§ 36-504 and 36-505 plainly provide that the appraisers in proceedings to condemn private property for public purposes shall assess actual damages for the property taken and consequential damages to the property not taken. Therefore, the award of damages and judgment of condemnation bar recovery of consequential damages except such as result from negligent and improper construction.

2. But where, due to a mistake of fact unmixed with negligence, the condemnation proceeding for a public road was conducted throughout upon the theory that the road would be paved at approximately grade level, thus improving rather than damaging the remaining abutting property, and there was nothing in the pleadings or evidence to indicate that a fill of from 25 to 40 feet would be made in front of the remaining property which would damage it in the amount of approximately $20,000, a petition in equity, alleging these facts and alleging that the mistake prevented the owners from proving this consequential damage, alleges a cause of action to set aside the award and the judgment of condemnation and to recover the full damages.

3. Since the petition alleges grounds to set aside the condemnation proceeding, which would, when done, reinvest the petitioners with title, the further prayer for cancellation of the deed from Houston County to the Rural Roads Authority, purporting to convey this same land, upon the ground that the county had no title, alleges grounds for the relief prayed, and the court erred in sustaining the demurrer of the defendant Houston County to the petition.

ARGUED SEPTEMBER 9, 1958 — DECIDED NOVEMBER 7, 1958.

This entire matter had its origin in a resolution by the County Commissioners of Houston County, adopted on March 10, 1956, in which it is recited that the Georgia Rural Roads Authority desires to construct a road on the land in question; that the county has authority under the law to provide and pay for the right-of-way; that it is not a part of the State-aid system of highways; and that the county shall furnish the right-of-way and will be responsible for all direct and consequential damages resulting from the appropriation and construction. Next, the county commissioners executed a deed conveying the land in question to the Georgia Rural Roads Authority, and the county attorney, J. W. Bloodworth, certified that the deed conveyed good title. Then the county attorney addressed a letter to one of the owners, Mr. Whipple, advising that he was enclosing therewith an offer for his acceptance or rejection before condemnation of property owned by Whipple and Dr. Barksdale, the offer describing the land here involved and in the amount of $1,000. The county attorney's letter stated in part: "The county will build a road that will materially enhance your property. You will have considerable paved road frontage which you will not have if the project is abandoned." It concluded by saying: "I am instructed that in the event of a failure to agree, for me to proceed to condemn the property in the name of the State Highway Department." This letter was signed by Bloodworth and dated April 6, 1956. A petition in the superior court seeking to condemn the same land and describing it as Project No. 2423 (1) and as a part of the system of State Highways as provided by the 1919 and 1921 acts was signed by Eugene Cook, Attorney-General, and J. W. Bloodworth, attorneys for the petitioner, and the judge entered an order thereon for service, dated April 14, 1956. Appraisers were appointed, qualified, and made an award of $1,000 actual and $125 consequential damages. This was paid and accepted, and the court entered a judgment decreeing title in the State Highway Department to be used as a Georgia post road.

The present petition by the owners against the State Highway Department, the Georgia Rural Roads Authority, and Houston County seeks to cancel the deed executed by Houston County to the Rural Roads Authority, the award of the appraisers, and the judgment of the court entered thereon; and petitioners pay into court the amount of the award as a refund. The petition alleges that the county commissioners represented to the owners in the presence of the State Highway engineer who drew the specifications for the road that it would be constructed at ground level, and the engineer did not dissent; that the appraisal of value by the appraisers was made upon the assumption and mistake of fact that the construction of the road would be done on a grade with abutting property; but the Highway Department and the Rural Roads Authority have constructed the road making a fill from 25 to 40 feet above the level of the land and thus virtually destroyed the value of the abutting land. The petition also contains allegations that the defendants are encroaching upon other lands of petitioners not embraced in the condemnation proceedings. A judgment for $20,000 in damages is prayed. The petition thus alleges that the condemnation award and judgment resulted from a mutual mistake of fact on the part of the petitioners, the representatives of Houston County, and the assessors in the condemnation proceedings. The actions leading to and consummated in the judgment of the superior court condemning the road right-of-way ties in Houston County as one of the condemnors to the extent that the owners were justified in relying upon the actions and representations of the county, and the State Highway Department is bound by the actions of the county. The petition as amended was in four counts. To the judgment sustaining demurrers and dismissing the petition the petitioners except.

DUCKWORTH, Chief Justice.

1. This four-count petition, together with the exhibits attached thereto and made a part thereof, is voluminous and consequently difficult to evaluate without a simultaneous consideration of the statutory law embodied in Code (Ann.) Ch. 95-26 (Ga. L. 1955, pp. 124, 131). The real complaint of the petition is the construction of the road by making a fill of a height of from 25 to 40 feet above the petitioners' abutting land and the damages resulting therefrom, together with an encroachment upon the petitioners' land not embraced in the right-of-way. The petition does not charge that the construction causing the damages complained of is either improperly or negligently done. Consequently, the petitioners' right to complain thereof is precluded by the condemnation proceedings unless and until they are set aside. The statute plainly provides that the assessors shall assess consequential damages to the property not taken. Code §§ 36-504, 36-505. The decisions in McArthur v. State Highway Department, 85 Ga. App. 500 ( 69 S.E.2d 781), Central Georgia Power Co. v. Mays, 137 Ga. 120 ( 72 S.E. 900), do no more than allow a recovery for damages resulting from negligent and improper construction. Construction that is done with due care and is proper is not grounds for recovery for damages to the remainder of the property of the condemnee. The assessment of compensation for land taken covers all damages whether foreseen or not which results from a proper construction. Gilbert v. Savannah, Griffin c. R., 69 Ga. 396. See, on facts similar to the complaint here, State Highway Board v. Shierling, 51 Ga. App. 935 ( 181 S.E. 885), holding that the judgments on condemnation do preclude any future claim by the owner of consequential damages to the remaining property resulting from a careful and proper construction.

2. Therefore, it is imperative that the prayer for cancellation and setting aside of the award and judgment of condemnation be sustained if the petitioners are to be allowed to recover for alleged damages resulting from the manner of construction, which is making a fill in heights from 25 to 40 feet in front of the owners' remaining lands.

This relief is sought upon the basis of mistake as described and contemplated in Code §§ 110-710, 37-202, 37-203, 37-206, 37-219, and 37-220. Counsel cite Callan Court Co. v. C. S. Nat. Bank, 184 Ga. 87, 129 ( 190 S.E. 831), for a definition of a mistake relievable against in equity. The mistake thus relievable is described in that decision as "an erroneous mental condition, conception, or conviction induced by ignorance, misapprehension, or misunderstanding of the truth, but without negligence and resulting in some act or omission done or suffered erroneously by one or both the parties to a transaction, but without its erroneous character being intended or known at the time." Agreeing in substance with the foregoing definition and ruling are 30A Am. Jur. 713, § 769, and 49 C. J. S. 723, § 365. See also Pearce Co. v. Chastain, 3 Ga. 226 (46 Am. D. 423); Pollock v. Gilbert, 16 Ga. 398 (60 Am. D. 732); Brewer v. Jones, 44 Ga. 71; Simmons v. Martin, 53 Ga. 620; and 30A Am. Jur. 710, § 765, "Judgments." These authorities require a ruling that, if these petitioners were, due to mistake unmixed with negligence, prevented in the condemnation proceeding from proving as consequential damages the construction of the fill here complained of and its resulting injury to the abutting property, and that the assessors who fixed the damage and the court which approved the valuation were kept ignorant of an intention to construct the fill, good grounds are shown for setting the award and judgment of condemnation aside.

To construe correctly the acts and conduct of the Houston County Commissioners and their attorney in connection with this matter, it is essential to have in mind portions of Code (Ann.) Ch. 95-26 (Ga. L. 1955, pp. 124, 148). This act provides that the State Highway Department shall initiate all rural road projects and the Authority may accept and agree to finance them or reject them. The act also provides that the Highway Department shall draw all plans and specifications and supervise construction. The Highway Department has power to acquire the right-of-way by condemnation. Code (Ann.) § 95-2606 (c). The governing authorities of any county are authorized and empowered to convey to the Authority any real property or any right-of-way now or hereafter owned by the county to be used as a rural road. Code (Ann.) § 95-2606 (b).

With the foregoing relevant rules of law in mind, we consider the alleged facts relating thereto. First, the Commissioners of Houston County, although having no title, executed a deed purporting to convey the right-of-way here involved to the Rural Roads Authority. Then their county attorney executed his certificate that the deed conveyed good title. This same county attorney, J. W. Bloodworth, on April 6, 1956, wrote the owners, who are the petitioners in this case, enclosing the county's offer to buy the right-of-way for $1,000, and requesting an acceptance or rejection, stating that the proposed road would enhance the lands of petitioners abutting on that road, and advising further that he had been instructed by the county authorities to institute condemnation proceedings in the name of the State Highway Department if the offer was rejected. On April 14, a petition in the name of the State Highway Department, signed by Eugene Cook, Attorney-General, and the county attorney, J. W. Bloodworth, as attorneys for the petitioner, was filed, praying for condemnation of the right-of-way.

The instant petition alleges that the appraisers, duly appointed, determined the damages, both actual and consequential, which would result if the road would be constructed at grade level; that both the petitioners and the assessors believed and acted upon the assumption that the road would be constructed at the existing elevation of petitioners' property; and that the petitioners had been repeatedly advised by the county commissioners and the county attorney that the road would be at grade level. This apparent careless use of the power of eminent domain was undeniably done in conjunction with the county, and with the knowledge of or chargeable with knowledge of the representations of the county attorney, who represented both the county and the Highway Department, that the road would be at grade level and hence beneficial to the remaining lands abutting thereon. The petition treats these representations as not having been made with fraudulent intent but rather in good faith because of ignorance of the true plans and facts held by the Highway Department. We pose this question: Would even an experienced lawyer have known exactly who was the true condemnor, and if the attorney Bloodworth was not attorney for both the county and the Highway Department? It is clear that he represented both and spoke for both. These owners were thus confronted with an unbroken chain of acts and steps to obtain this right-of-way and an attorney representing both the county and the Highway Department at every stage, representing that a paved road at grade level would be constructed on the right-of-way, enhancing the value of their property. It could not reasonably be required of these owners that in order to show diligence they should have disbelieved the condemnor in its representations through its attorney as to the character of the construction intended. The petition shows that, if the Highway Department had on file specifications that called for a fill of from 25 to 40 feet, it did not disclose this fact to the appraisers or to the owners, or even to Mr. Bloodworth, its attorney of record in the case. Therefore, a case of either mutual mistake, or mistake due to the fault of the opposite party, is clearly shown, and very great injury has resulted therefrom to the owners. This court can not hold that the owners, in order to show diligence, should have proven a manner of construction which was disclaimed by the attorney for the condemnor.

The petition shows great damages suffered by the owners, damages that they were prevented from proving before the appraisers solely by an honest mutual mistake, unmixed with negligence, or a mistake due to the fraudulent concealment of the condemnor unmixed with negligence or fault of the owners. Only equity can relieve against this unjust injury. Equity has that power. Courts of equity are courts of conscience. Equity considers that done which ought to be done and decrees accordingly. Another trial will do no more than require the State Highway Department to pay for what it takes from these private citizens. The Constitution, art. 1, sec. 1, par. 2, solemnly declares that "Protection to person and property is the paramount duty of government, and shall be impartial and complete." Code (Ann.) § 2-102. Here the State Highway Department and its attorneys are acting for the State and exercising the sovereign power of eminent domain, to take private property for a public use. When the State, through any of its agents, takes or damages private property for public purposes, the Constitution lays upon it the imperative duty to first pay just and adequate compensation therefor. Constitution, art. 1, sec. 3, par. 1 (Code, Ann., § 2-301). These are plain duties explicitly laid upon the State and all of its agents. Their sole purpose and object is the protection of the most humble person against tyrannical use or abuse of the powers of the State. A fair observance of these requirements would prevent the State and its agents, who are bound by the State's constitutional obligations, from desiring, intending to violate or actually violating the rights of the citizen. If by mistake the constitutional protection is denied the citizen, and it is not voluntarily rectified, courts of equity will command its rectification. It should never be a burden but rather a welcomed privilege for the State to accord fully these protections to the individual.

The plaintiffs have paid into court the amount awarded, which they accepted before they learned that the high fill now complained of would be constructed. They have done equity and now seek equity. The allegations are sufficient to warrant the relief of cancellation of the award and the judgment of condemnation, and to entitle the petitioners to a judgment awarding them compensation for direct and consequential damages. With this cancellation they are reinvested with title and consequently are entitled to have the deed from Houston County to the Rural Roads Authority canceled. The judgment sustaining the demurrers and dismissing the petition is erroneous.

Judgment reversed. All the Justices concur.
