(After stating the foregoing facts.) Section 1 of Ga. L. 1910, p. 131, provides: “Be it enacted, that in all counties in this State having a population of one hundred and twenty-five thousand (125,000), or more, the Board of County Commissioners, or if there be no such Board, the Ordinary of said county, shall have the power to grant or refuse permission to establish outside of the limits of incorporated towns, cemeteries, hospitals, sanatoriums, or similar institutions.” Ga. L. 1911, p. 200, sec. 1, provides that, “in all cases where it is
now
provided by the operation of existing laws that cemeteries . . . can not be established in the rural territory of any county without the permission of the Board of County Commissioners ... it shall be likewise unlawful to establish any such cemetery ... in any adjoining county without the permission” of the person or persons in charge of the county business.

While the defendants in that case and the defendants here are the same, and while the land in both cases is the same, the plaintiffs in the two cases are entirely different, and the petition in the

Neither does the rule of stare decisis — which is that a principle of law that has become settled by a series of decisions generally is binding on the courts and should be followed in similar cases — require that we follow the previous decision of this court in the
Herrod
case, supra. That is the first case, so far as we have been able to find, which holds that the rule announced by previous decisions of this court that reasonable classification by population renders an act general rather than special should be so extended as to make classification by population of one county the basis of applying the act to an adjoining county that does not have the required population. .We are convinced that this extension of the rule is unsound, and the doctrine of stare decisis should not be followed to the extent that error may be perpetuated. See, in this connection, 21 C. J. S. 302, § 187, and p. 322, § 193;
It is insisted by the defendants that, even if the act of ,1911 should be declared invalid, they would still have the right to establish a cemetery on the property involved, because, as they contend, there has been no valid zoning of the property exclusively for residential and agricultural purposes. It is insisted by the defendants that every statute enacted which purports to confer upon Cobb County the right to zone property is unconstitutional. We do not deem it necessary to deal with the various attacks made upon the act of 1943 (Ga. L. 1943, p. 902), as amended by the act of 1949 (Ga. L. 1949, p. 1499),
*217
purporting to confer upon the Planning Commission of Cobb County the power to zone property therein outside the incorporated cities, and creating a Board of Zoning Appeals, because, prior to either of those acts, and in 1937 (Ga. L. 1937-38, Ex. Sess., p. 790), the General Assembly passed an act conferring upon the County Commissioner of Cobb County the power to zone property outside the incorporated cities of the county. It appears from the record that, pursuant to that act, the County Commissioner did in 1939, by an ordinance adopted in conformity therewith, zone the property here involved exclusively for residential and agricultural purposes, and prohibited its use for any other purpose. Thus, conceding for the sake of argument, but not deciding, that the acts of 1943 and 1949 are unconstitutional to authorize zoning, they would likewise be ineffective to repeal the act of 1937, supra, and if that act and the zoning of the property involved thereunder be valid, the trial court should have enjoined its use for the establishment of a cemetery thereon.

v. Croft, 207

115 (3) (
From an examination of the act of 1937 (Ga. L. 1937-38, Ex. Sess., p. 790), it is perfectly clear that it was the intention of the General Assembly to confer upon the Commissioner of Roads and Revenues of Cobb County the power to enact zoning ordinances as had been authorized by the amendment to the Constitution of 1877 ratified June 8, 1937 (Ga. L. 1937, p. 1135, Code, Ann., § 2-1826), which conferred upon the General Assembly authority to grant to the governing authorities of any city or county in this State having a population of 1,000 or more, according to the Federal census of 1930, or any future census, the authority to pass zoning and planning laws whereby such cities or counties may be zoned or districted for various uses and other or different uses prohibited therein, etc. The governing authority referred to in the act of 1937 was the Commissioner of Roads and Revenues of Cobb County. If the 1937 act had simply declared a purpose to confer upon the Commissioner of Roads and Revenues of Cobb County authority to pass zoning and planning laws, it would have been sufficient without any reference to the act of the General Assembly creating that office, and without the necessity for an amendment to any particular statute. The fact that the author of the bill mistakenly referred to the act of 1921 will not destroy the act, for the reason that
*219
the legislative intent is plain and clear — to confer the power to enact zoning laws upon the county commissioner therein named. In

It is further contended by the defendants that the act of 1937 (Ga. L. 1937-38, Ex. Sess., p. 790) contravenes and is violative of article I, section IV, paragraph I of the Constitution of 1945 (Code, Ann., § 2-401), which provides: “Laws of a general nature shall have uniform operation throughout the State, and no special law shall be enacted in any case for which provision has been made by an existing general law,” and of the Constitution of 1945, article XI, section I, paragraph VI (Code, Ann., §,2-7806), which provides in part: “Whatever tribunal, or officers, may be created by the General Assembly for the transaction of county matters, shall be uniform throughout the State, and of the same name, jurisdiction, and remedies, except that the General Assembly may provide for Commissioners of Roads and Revenues in any county,” and similar provisions of the Constitution of 1877, in that said act constitutes a special law enacted in a case for which provision has been made by an existing general law, viz., the act approved August 10, 1910 (Ga. L. 1910, p. 130), and the act approved August 21, 1911 (Ga. L. 1911, p. 200); because there is a general law on zoning, viz., Code (Ann. Supp.) Ch. 69-8, and because there is an existing general law with respect to zoning, viz., the Airport Zoning Act, Code (Ann. Supp.) Ch. 11-4 (Ga. L. 1946, p. 121), and because
*221
said act does not have uniform operation throughout the State, but purports to permit Cobb County to have a particular system which is different from other systems of zoning throughout the State. None of these attacks upon the act is meritorious. We have here held that the act approved August 21, 1911 (Ga. L. 1911, p. 200), is invalid. In

It is further contended that the act of 1937 (Ga. L. 1937-38, Ex. Sess., p. 790) and all zoning thereunder is unconstitutional and void because violative of article I, section I, paragraph III of the Constitution of Georgia of 1945 (Code, Ann., § 2-103), and the similar provisions of the Constitution of 1877, that no person shall be deprived of life, liberty, or property, except by due process of law, and of the due-process clauses of the 5th and 14th amendments to the Constitution of the United States (Code §§ 1-805 and 1-815); and that the zoning of the property of the defendants exclusively for residential and agricultural purposes is arbitrary, unreasonable, capricious, and unenforceable.

It is further contended by the defendants that the act of 1937 (Ga. L. 1937-38, Ex. Sess., p. 790), is unconstitutional and void because it is violative of article V, section I, paragraph XII of the Constitution of 1945 (Code, Ann., § 2-3012), and similar *222 provisions of the Constitution of 1877, that no law shall be enacted at called sessions of the General Assembly except as shall relate to the object stated in the proclamation convening them, in that the act of 1937 does not relate to the object stated in the Governor’s proclamation convening the 1937-38 extra session of the General Assembly. This contention is also without merit. As already pointed out, the amendment to the Constitution of11877 (Code, Ann., § 2-1826), which conferred upon the General Assembly the power to grant to governing authorities of Cobb County the authority to pass zoning and planning laws, was ratified at the general election held on June 8, 1937. The act here under attack was enacted at the 1937-38 extra session of the General Assembly and was approved on December 27, 1937. Reference to the proclamation of the Governor convening that session of the General Assembly (Georgia House Journal, Extraordinary Session 1937-38, pp. 7 and 8) shows that it contained the following: “Whereas, the people of Georgia have ratified in a popular election a number of amendments to the Constitution of this State, in the General Election of June 8, 1937, which election was held since the last regular session of the General Assembly; and Whereas, it is necessary to have certain enabling acts and legislation to put into effect the objects and purposes included in said amendments to the Constitution; and, . . . Now, therefore, under and by virtue of the provisions of law contained in Article Y, Section I, Paragraph XIII of the Constitution of Georgia, I, E. D. Rivers, Governor of Georgia, do hereby convoke and call a meeting of the General Assembly of this State in Extraordinary Session at 10:00 o’clock A. M., on Monday, November 22, 1937, for the purpose of considering and enacting laws and resolutions, by revision, repeal, amendment, or otherwise, relating to all of the following objects, which are considered by the Executive of sufficient importance to make the necessity for such Extraordinary Session, to wit: . . . Enabling acts for all constitutional amendments ratified at the General Election held on June 8, 1937, and laws relating to such amendments.”
The foregoing rulings being controlling in the instant case, it becomes unnecessary to pass upon other constitutional attacks made by the defendants upon other statutes and chapters of the *223 Code. For the reasons herein pointed out, the judgment of the trial court must be
Reversed.
