8100 NORTH FREEWAY LTD., Appellant,
v.
CITY OF HOUSTON, Appellee.
No. 14-09-00220-CV.
Court of Appeals of Texas, Houston (14th Dist.).
December 2, 2010.
*860 Richard B. Kuniansky, Houston, for appellant.
Lisa A. Brown, Nirja S. Aiyer, Patrick Zummo, Houston, Bradley J. Reich, Aurora, for appellee.
Panel consists of Chief Justice HEDGES and Justices YATES and SULLIVAN.

OPINION
LESLIE B. YATES, Justice.
Appellant 8100 North Freeway Ltd. appeals the trial court's order granting the temporary injunction request of appellee the City of Houston. Because we find that the trial court did not abuse its discretion in issuing the temporary injunction, we affirm.

BACKGROUND
The City regulates sexually oriented businesses (SOBs) and requires them to meet certain criteria to obtain permits, which are necessary for legal operation. 8100 operates a business, originally called Adult Video Megaplexxx, consisting of an adult bookstore and adult arcade that features small booths with doors where adults may privately view sexually explicit videos. A portion of the City's SOB ordinance specifically regulates adult arcades and requires, among other things, minimal lighting levels inside the booths and a direct line of sight between the manager and the booth patron. These requirements were enacted to discourage sexual activity in arcade booths. See Rosenblatt v. City of Hous., 31 S.W.3d 399, 404 (Tex.App.-Corpus Christi 2000, pet. denied). Megaplexxx attempted to comply with the ordinance by installing video cameras in the booths. See id. at 402. The City denied Megaplexxx a permit because it did not comply with the direct line of sight provision, and the City's action was upheld in the trial court and on appeal. See id. at 401.
Megaplexxx then changed its business model in an attempt to avoid being subject to the ordinance. It changed its name to Tryst, A Lover's Boutique, and began offering several new types of inventory, including condoms, oils, lingerie, costumes, and adult novelties. 8100 expanded the video arcade from nine to twenty-eight viewing rooms and added more viewing channels, for a total of sixty-three channels showing various types of adult videos and sixty-four channels offering mainstream movies. By making these changes, 8100 attempted to cast itself as a "fifty/fifty" business rather than an adult arcade requiring a permit.
*861 A Houston Police Department officer inspected the premises. He observed a sign on the front door prohibiting minors. Inside, signage directed patrons to the arcade area, touting "hardcore" channels. The arcade area spanned three hallways, and all arcade booths had closable doors. A television hanging from the ceiling above the entrance to the arcade area continuously displayed videos depicting explicit sexual activity. Inside a booth, the officer observed a money-operated arcade device that displayed videos depicting explicit sexual activity, along with a chair, paper towels, and a trashcan.
The City brought suit against 8100 for operating an adult arcade without a permit and sought injunctive relief. The trial court granted the City's request for a temporary injunction on March 5, 2009, and ordered that the arcade area be locked and that 8100 cease from operating its arcade devices. 8100 filed its appeal the same day, but to date, no permanent injunction hearing has been held.

ANALYSIS

A. Legal Standards
The purpose of a temporary injunction is to preserve the status quo pending a trial on the merits. Butnaru v. Ford Motor Co., 84 S.W.3d 198, 204 (Tex. 2002); EMS USA, Inc. v. Shary, 309 S.W.3d 653, 657 (Tex.App.-Houston [14th Dist.] 2010, no pet.). Generally, to obtain a temporary injunction, the applicant must prove a valid cause of action against the defendant, a probable right to relief, and imminent, irreparable injury in the interim. See Butnaru, 84 S.W.3d at 204; EMS, 309 S.W.3d at 657. However, when the applicant has shown a violation of a statute that authorizes injunctive relief, it need not prove imminent, irreparable injury. See Butnaru, 84 S.W.3d at 210; West v. State, 212 S.W.3d 513, 518-19 (Tex.App.-Austin 2006, no pet.); Ralph Williams Gulfgate Chrysler Plymouth, Inc. v. State, 466 S.W.2d 639, 642 (Tex.Civ.App.-Houston [14th Dist.] 1971, writ ref'd n.r.e.). Further, the applicant need not prove that it will prevail, and the merits of the suit are not issues for appellate review. See EMS, 309 S.W.3d at 658. Rather, we review the trial court's decision on a temporary injunction request for an abuse of discretion. Butnaru, 84 S.W.3d at 204; EMS, 309 S.W.3d at 658. We must not substitute our judgment for the trial court's judgment and may not reverse unless the trial court's action was so arbitrary that it exceeded the bounds of reasonableness. See Butnaru, 84 S.W.3d at 204.

B. The Primary Business Standard Does Not Apply
In its first issue, 8100 argues that the trial court erred in granting a temporary injunction because the SOB ordinance regarding adult arcades applies only to entities whose primary business is to provide sexual stimulation or gratification and, because its inventory of movies is over fifty percent non-adult, its primary arcade business is not sexual.
Local Government Code chapter 243, entitled "Municipal and County Authority to Regulate Sexually Oriented Business," defines a sexually oriented business as follows:
[A] sex parlor, nude studio, modeling studio, love parlor, adult bookstore, adult movie theater, adult video arcade, adult movie arcade, adult video store, adult motel, or other commercial enterprise the primary business of which is the offering of a service or the selling, renting, or exhibiting of devices or any other items intended to provide sexual stimulation or sexual gratification to the customer.
*862 TEX. LOC. GOV'T CODE ANN. § 243.002 (West 2005). The City has regulations regarding SOBs in two portions of chapter 28 of the City of Houston Code of Ordinances: article II, which governs adult arcades and adult mini-theaters, and article III, which governs SOBs generally. HOUSTON, TEX., REV. ORDINANCES ch. 28, arts. II, III (1997). Article II defines an adult arcade as "any premises that is subject to regulation under Chapter 243 of the Local Government Code, as amended, to which members of the public . . . are permitted to use one or more arcade devices." Id. art. II, § 28-81. An "arcade device" is "any coin- or slug-operated or electronically or mechanically controlled machine or device that dispenses or effectuates the dispensing of entertainment, that is intended for the viewing of five or fewer persons in exchange for any payment of consideration," and "entertainment" includes "[a]ny still picture(s) or movie picture(s)." Id.
8100 contends that because article II's definition of adult arcade refers back to chapter 243 and chapter 243's definition of SOB includes the notion of primary business, it is subject to article II's regulation only if its primary business is to provide sexual stimulation or gratification. We disagree. Chapter 243's definition contains a list of establishments that are categorically considered SOBs and then contains a catch-all for other businesses not listed but whose primary business is providing sexual stimulation or gratification. See Meijas v. State, No. 04-01-00048-CR, 2002 WL 112534, at *1 (Tex. App.-San Antonio Jan. 30, 2002, pet. ref'd) (not designated for publication); see also N.W. Enters. Inc. v. City of Hous., 352 F.3d 162, 184 (5th Cir.2003); Laredo Road Co. v. Maverick Cnty., 389 F.Supp.2d 729, 734-35 (W.D.Tex.2005). An adult video arcade is in the list of categorical SOBs, and thus the primary business analysis is irrelevant. See Meijas, 2002 WL 112534, at *1. 8100 insists that the primary business language in chapter 243 modifies not just the catch-all "other commercial enterprise" but also the entire list of enumerated businesses. However, such an interpretation is grammatically incorrect.[1] Under the last antecedent rule, a limiting clause or phrase should ordinarily be read as modifying only the noun or phrase that it immediately follows. See Barhnart v. Thomas, 540 U.S. 20, 26, 124 S.Ct. 376, 157 L.Ed.2d 333 (2003); Laredo Road, 389 F.Supp.2d at 735; Rowan Cos. v. Wilmington Trust Co., 305 S.W.3d 698, 710-11 (Tex.App.-Houston [14th Dist.] 2009, pet. filed). Had the legislature intended the primary business phrase to modify the entire list rather than only the last item, it would likely have included a comma between "other commercial enterprise" and "the primary business of which." See Elliot Coal Mining Co. v. Office of Workers' Comp. Programs, 17 F.3d 616, 629-30 (3d Cir.1994); Bingham, Ltd. v. United States, 724 F.2d 921, 925 n. 3 (11th Cir. 1984); Meijas, 2002 WL 112534, at *1.
*863 The trial court found in its temporary injunction order that 8100 is operating an adult arcade without a permit as required by article II. 8100 does not dispute that Tryst has arcade devices that are open to the public for a fee, that they display both pornographic and non-pornographic movies, and that Tryst does not have an article II permit. We conclude the trial court did not abuse it discretion in granting a temporary injunction on this basis. Tryst's primary business is not relevant to this inquiry, and we overrule 8100's first issue.[2]

C. Injunctive Relief Was Proper
8100 raises several issues regarding the propriety of injunctive relief in this case. In its fifth issue, 8100 asserts that the trial court abused its discretion in issuing the injunction because the ordinance does not authorize injunctive relief for a violation of article II. Article III of the SOB ordinance specifically states that "[t]he city attorney is hereby authorized to file suit to enjoin the violation of this article." HOUSTON, TEX., REV. ORDINANCES ch. 28, art. III, § 28-134. Article II, however, is silent on the issue of authority to pursue an injunction. Based on this, 8100 argues that the City is not authorized to seek an injunction for violation of article II. This argument overlooks the significance of chapter 243 of the Local Government Code. Chapter 243 authorizes municipalities to regulate SOBs and then specifically states that a municipality "may sue in the district court for an injunction to prohibit the violation of a regulation adopted under this chapter." TEX. LOC. GOV'T CODE ANN. § 243.010(a) (West 2005); see also Smartt v. City of Laredo, 239 S.W.3d 869, 873 (Tex.App.-Amarillo 2007, pet. denied) (stating that chapter 243 authorizes cities to seek injunctions to stop violations of SOB ordinances); Schleuter v. City of Fort Worth, 947 S.W.2d 920, 932 (Tex.App.-Fort Worth 1997, writ denied) (same). The City's silence regarding injunctions in article II does not evidence any intent to relinquish the authority specifically provided by the legislature in chapter 243.[3] Indeed, article II states that its provisions "are supplemental and shall be cumulative with all other laws and ordinances applicable in any manner to an adult arcade." HOUSTON, TEX., REV. ORDINANCES ch. 28, art. II, § 28-83. We conclude that the City was authorized to pursue injunctive relief for a violation of article II, and we accordingly overrule 8100's fifth issue.
In its sixth issue, 8100 contends that the trial court abused its discretion in ordering injunctive relief because the relief goes beyond preserving the status quo. The goal of a temporary injunction is to preserve the status quo, and the status quo in this context is the last actual, peaceable, uncontested state of affairs that preceded the pending controversy. See Law v. William Marsh Rice Univ., 123 S.W.3d 786, 791 (Tex.App.-Houston [14th Dist.] 2003, pet. denied). It follows that the status quo can never be a state that allows a party to continue violating the law. See San Miguel v. City of Windcrest, 40 S.W.3d 104, 109 (Tex.App.-San Antonio 2000, no pet.); Hous. Compressed Steel Corp. v. State, 456 *864 S.W.2d 768, 773 (Tex.Civ.App.-Houston [1st Dist.] 1970, no writ). In this case, the trial court determined that 8100 was violating the law by operating an adult arcade without a permit, and we have already determined the trial court did not abuse its discretion in so determining. Thus, the temporary injunction preserved a status in which 8100 was not violating the ordinance, and we overrule 8100's sixth issue.
In its eighth issue, 8100 claims that the trial court abused its discretion in issuing the temporary injunction because the injunction constitutes an unlawful prior restraint on protected First Amendment activities. The United States Supreme Court has rejected this argument, holding that the closure of an adult bookstore for failure to comply with a local ordinance was not an unlawful prior restraint because the order did not prohibit the defendants from disseminating particular materials and because the order was not based on an advance-determination that the distribution of certain materials is prohibited. See Arcara v. Cloud Books, Inc., 478 U.S. 697, 706 n. 2, 106 S.Ct. 3172, 92 L.Ed.2d 568 (1986). Similarly, 8100 is free to continue showing its videos as long as it complies with the City's ordinance, and the injunction is not based on the content of the movies shown but rather the environment in which they are shown. Based on Arcara, we conclude the temporary injunction order does not constitute an unlawful prior restraint, and we overrule 8100's eighth issue.
In its ninth issue, 8100 argues that the trial court erred in denying its request to impose a stay on the enforcement of the temporary injunction pending appeal. 8100 states in its brief that "[t]his issue may be moot," and we agree. 8100 filed a motion to stay in this court and then withdrew that motion before our ruling based on the City's agreement not to enforce the injunction pending appeal. Further, appellate review of the appeal is now complete. Thus, any issue of a stay pending appeal is moot. See Maloy v. City of Lewisville, 848 S.W.2d 380, 383 (Tex.App.-Fort Worth 1993, no writ). We overrule 8100's ninth issue.
Finally, in its reply brief, 8100 asserts that the trial court's injunction order is overbroad because it requires the entire arcade section to be locked, rendering it unusable for other purposes such as a lingerie area. By failing to raise this issue in its opening brief, 8100 has waived it. See Zamarron v. Shinko Wire Co., 125 S.W.3d 132, 139 (Tex.App.-Houston [14th Dist.] 2003, pet. denied).

D. No Advance Ruling on the Merits
In its second and third issues, 8100 makes various arguments as to why the SOB ordinance is unenforceable and unconstitutional, including that it is vague and overbroad and provides for unfettered police discretion. We conclude that we cannot address these issues because they are beyond the scope of our review.
A temporary injunction hearing and a trial on the merits have different functions:
[O]ur system of procedure is such that legal rights cannot be finally determined upon a hearing relating to the wisdom or expediency of issuing a status quo order. Deliberate action is essential for the accurate determination of legal rights and upon occasion this can be secured only by issuing a temporary decree protecting a status quo. Ordinarily, the hearing upon the temporary injunction is not a substitute for, nor does it serve the same purpose as the hearing on the merits.
Tom James of Dall., Inc. v. Cobb, 109 S.W.3d 877, 884 (Tex.App.-Dallas 2003, no pet.) (quotation marks omitted). Simply put, a temporary injunction is not a ruling *865 on the merits. See EMS, 309 S.W.3d at 658; Tom James, 109 S.W.3d at 884. Accordingly, we may not review the merits of the underlying litigation on appeal. See Sharma v. Vinmar, Int'l, Ltd., 231 S.W.3d 405, 419 (Tex.App.-Houston [14th Dist.] 2007, no pet.); Law, 123 S.W.3d at 792. Our review is solely limited to whether the trial court abused its discretion in issuing the temporary injunction. Law, 123 S.W.3d at 792; San Miguel, 40 S.W.3d at 107.
The issue before the trial court was whether the City was entitled to a temporary injunction, not whether the ordinance was enforceable or constitutional. Indeed, the trial court found that 8100 was operating a business in violation of article II, but it did not issue any rulings regarding the constitutionality or enforceability of the ordinance. In its second and third issues, 8100 does not argue that the trial court abused its discretion in issuing the temporary injunction; rather, it argues that the ordinance upon which it is based is unenforceable and unconstitutional. These issues are dispositive of 8100's defenses in the underlying litigation and therefore are not appropriate subjects for appellate review in this interlocutory appeal.[4] We will not issue an advance ruling on the merits by addressing these issues before the trial court has done so. See Brar v. Sedey, 307 S.W.3d 916, 920 (Tex.App.-Dallas 2010, no pet.).

CONCLUSION
The trial court did not abuse its discretion in issuing a temporary injunction against 8100. We affirm the trial court's order.

NOTES
[1]  8100 points to other cases in which courts have discussed the primary business standard. See 4330 Richmond Ave. v. City of Hous., No. Civ.A. 91-0665, 1997 WL 1403893 (S.D.Tex. July 17, 1997), aff'd, 166 F.3d 338 (5th Cir.1998) (table); Griswold v. State, No. 07-00-0203-CR, 2001 WL 830348 (Tex.App.-Amarillo July 24, 2001, pet. ref'd) (not designated for publication); Collins v. State, No. 14-00-00482-CR, 2001 WL 421258 (Tex. App.-Houston [14th Dist.] Apr. 26, 2001, pet. ref'd) (not designated for publication); Hernandez v. State, No. 14-99-00671-CR, 2000 WL 991806 (Tex. App.-Houston [14th Dist.] July 20, 2000, no pet.) (not designated for publication). These cases are distinguishable because they involve adult bookstores, and article III defines adult bookstore with specific reference to the primary business of the store. See HOUSTON, TEX., REV. ORDINANCES ch. 28, art. III, § 28-121.
[2]  Because we have concluded that the primary business standard does not apply in this context, we need not address 8100's fourth and seventh issues, both of which involve defining the primary business standard.
[3]  8100 argues that perhaps the City intentionally omitted any reference to injunctive relief in article II based on concerns over suppression of speech protected by the First Amendment, but that argument fails because article III, which specifically covers adult bookstores and materials therein protected by the First Amendment, provides for injunctive relief.
[4]  See San Miguel, 40 S.W.3d at 109 (stating that temporary injunction did not resolve issues regarding vagueness and constitutionality of ordinance); T & R Assocs. v. City of Amarillo, 601 S.W.2d 178, 180 (Tex.Civ.App.-Amarillo 1980, no writ) (noting that grounds to escape enforcement of ordinance may not be entertained on appeal of temporary injunction because they relate to the merits); Hous. Compressed, 456 S.W.2d at 774 (stating that arguments that statute is vague and indefinite are not before the court on appeal of temporary injunction); see also EMS, 309 S.W.3d at 658 ("[A]ny appeal of an order granting or denying a temporary injunction based on a non-compete covenant does not present for appellate review the ultimate question of whether the covenant is enforceable. . . .").
