G.S. 18A-33(b) reads in pertinent part:

“In addition to the restrictions on the sale of malt beverages and/or wines (fortified or unfortified) set out in this section, the governing bodies of all municipalities and counties in North Carolina shall have, and they are hereby vested with, full power and authority to regulate and prohibit the sale of malt beverages and/or wine (fortified or unfortified) from 1:00 p.m. on each Sunday until 7:00 a.m. on the following Monday. Provided, however, that municipalities and counties shall have no authority under *584this subsection to regulate or prohibit sales after 1:00 p.m. on Sundays by establishments having a permit issued under Article 3 of this Chapter.”

Plaintiffs assert that the statute is unconstitutional as it violates the equal protection clause of the Constitution of North Carolina, Article 1, Section 19, and the Fourteenth Amendment of the Constitution of the United States, and that the ordinance of the town of Gibsonville based thereon which prohibits sale of beer and wine on Sunday after 1:00 p.m. is void.

The State maintains that the enactment of G.S. 18A-33 (b) is within the constitutional power of the General Assembly and the holding of the court below limiting the effect of the proviso contained in G.S. 18A-33 (b) is error.

We hold that G.S. 18A-33(b) without the proviso limiting its application is a valid exercise of the police power of this State and grants to the town of Gibsonville the authority to place and enforce a total ban on the sale of beer and wine on Sundays after 1:00 p.m. There is a total ban imposed upon Sunday sales until 1:00 p.m. by G.S. 18A-33 (a).

The proviso in G.S. 18A-33(b) confers a special privilege upon holders of Article 3 or “brown bagging” permits who also hold beer and/or wine permits to sell beer and/or wine on Sundays after 1:00 p.m. when other competing businesses, such as plaintiffs, are not so allowed.

Conceding that the General Assembly has the authority to establish different permit categories for types of establishments which sell beer and wine and establishments which permit the consumption of other alcoholic beverages on their premises, the classification of the types of permit holders must be based on reasonable distinctions and affect all persons in like situations or engaged in the same business without discrimination. This principle was succinctly stated in Cheek v. City of Charlotte, 273 N.C. 293, 298, 160 S.E. 2d 18, 23, as follows: “Statutes and ordinances ‘are void as class legislation . . . whenever persons engaged in the same business are subject to different restrictions or are given different privileges under the same conditions.’ ”

The General Assembly likewise has the unquestioned authority to grant to municipalities the authority to pass ordinances relating to the sale of beer and wine as long as they are not *585discriminatory. Here the town of Gibsonville has exercised this authority granted by the General Assembly and has passed an ordinance which places a ban on Sunday sales of beer and wine. The effect of the proviso in G.S. 18A-33 (b), however, is to exclude a class of citizens from the application of the ordinance without any logical basis for such exclusion. As the statute now reads with the proviso holders of Article 3 or “brown bagging” permits who also hold permits to sell beer and/or wine are not to be governed by the same regulations which are applicable to other competing establishments which hold only permits to sell beer and/or wine and who may desire to engage in the sale of beer and/or wine after 1:00 p.m. on Sundays. This cannot be sustained.

It is difficult to see how permitting one group to sell beer and wine after 1:00 p.m. on Sundays and forbidding another competing group to do so, particularly in the sale of beer for consumption off premises, can be other than discriminatory. This is all the proviso does, and it cannot be rationally justified upon any basis in keeping with the regulation and control of the sale of beer and wine. As to the sale for off-premises consumption, which is the area in which plaintiffs are in competition with holders of “brown bagging” permits, it makes little difference where beer or wine may be purchased if it is to be consumed elsewhere. Indeed it would seem logical that an establishment which is authorized to permit consumption of alcoholic beverages on its premises (holders of “brown bagging” permits) may be less desirable as a place to purchase beer and/or wine on Sunday after 1:00 p.m. than a grocery store which could only sell beer for off-premises consumption. Suffice it to say the proviso excluding “brown bagging” permit holders from the ban on Sunday sales of beer and/or wine after 1:00 p.m. is an impermissible discrimination arbitrarily established between competing businesses in similar situations which has no reasonable relation to the purpose of the law. State v. Greenwood, 280 N.C. 651, 187 S.E. 2d 8; Cheek v. City of Charlotte, supra; State v. Smith, 265 N.C. 173, 143 S.E. 2d 293; State v. Glidden Co., 228 N.C. 664, 46 S.E. 2d 860.

The ordinance of the town of Gibsonville as authorized by G.S. 18A-33(b) is valid and enforceable against all its citizens without discrimination. G.S. 18A-33(b) is a constitutional exercise of the power of the General Assembly except for the proviso which excludes businesses with Article 3 or “brown *586bagging” permits from the remainder of G.S. 18A-33(b). The proviso is unconstitutional and void. The judgment below is modified to permit the town of Gibsonville to enforce its ordinance against the sale of beer and wine on Sundays after 1:00 p.m. without restriction.

Modified and affirmed.
