It is stipulated that the lands involved were taken on May 4, 1965. The record shows that the trial ended December 1, 1965, and the 1966 Act defining just and adequate compensation (Ga. L. 1966, p. 320) was approved March 10, 1966. This court ruled in
Hard v. Housing Authority of the City of Atlanta,
The decisive question here is: Does the Constitution, Art. I, Sec. Ill, Par. I, supra, vest in every landowner in Georgia a right to employ evidence, held by this court in the
Hard
case, supra, to be admissible in proof of “just and adequate compensation” for same when taken for public use? It commands that he be paid just and adequate compensation. What is just and adequate is a justiciable question, and under the constitutional clause
(Code Ann.
§ 2-123; Const, of 1945) requiring separation of powers, only the judiciary can lawfully determine that question. Can it be seriously doubted that the bill of rights vests interests in the individual? None of the three separate departments of the state — legislative, executive or judicial, has the power to reduce or abolish the constitutional right of the owner to receive just and adequate compensation for his private property taken for a public use. Only the judiciary can adjudicate the amount of such compensation and what evidence is relevant and admissible for that purpose. This court performed its duty in that respect in the
Hard
case. The purported exercise of judicial powers by the 1966 Act, purportedly overruling a judgment of this court, is void on its face; and the vested right of the owners can not be destroyed by applying the 1966 Act to a case that has already been tried. We are aware of the well-known rule that until time for review has passed a party to a judgment has no vested interest in it. See
Franklin v.
Harper,
It is beyond the power of the General Assembly to specify what evidence can or can not be introduced to prove just and adequate compensation. If they have such power they could exclude all evidence and thus destroy the Constitution and private property also. If they can by the 1966 Act exclude evidence held judicially to be relevant and admissible as was done in the
Hard
case, they can render the judiciary impotent. See
McCutcheon v. Smith,
It is firmly established by the decisions of this court that challenges to the constitutionality of statutes must be made at the first opportunity, and must have been ruled upon by a lower court before this court will rule upon them. But the factual situation in this case raises a serious question as to whether, in the light of the provisions of the Constitution (Code Ann. § 2-4021; Const, of 1945) that legislative acts which violate the Constitution are void, and it is the duty of the judiciary to so declare them, this court can avoid that duty because of the above rules, which it was impossible to follow here. The trial was finished on December 1, 1965, and the 1966 Act was approved March 10, 1966. The appeal was by the Constitution required to be made to the Court of Appeals which has no jurisdiction to decide constitutional questions. The Act first entered the case in the Court of Appeals, being injected into the case by that court. Code § 3-105. Could the Act, clearly void on its face, be employed to the injury of a party because he had not obtained a ruling in the trial court which was impossible when he here urges its unconstitutionality at his first opportunity in a court with jurisdiction to decide it? In the circumstances should landowners and trial courts be left in the dark as to whether or not the 1966 Act is void? Here is demonstrated the everlasting truth that there are exceptions to all rules. All cases factually identical with this one will be *69 •unjustly decided if this court applies the above rules. But by making such cases exceptions to the general rule and deciding them, justice will be done, and no one will be denied justice. We therefore hold that for the reason that the 1966 Act is an attempt to invade the exclusive jurisdiction of the judicial department, it offends the constitutional separation of powers and is therefore void.
Judgment reversed.
