ROCKDALE COUNTY. v. U. S. ENTERPRISES, INC.; And Vice Versa

William Corey and U.S. Enterprises wanted to build a QuikTrip gas station and convenience store near Interstate 20 in Rockdale County. The County denied their building permit, saying the facility was really a 'truck stop,' a use banned everywhere in the county under its zoning rules, the Unified Development Ordinance. After the County's Board of Adjustment upheld that denial, the Owners went to superior court, arguing the case was already settled in their favor by a much earlier lawsuit and that the ordinance's definition of 'truck stop' was so unclear it violated their right to due process. The superior court agreed the definition was unconstitutionally vague and reversed the permit denial. The Supreme Court of Georgia disagreed on the vagueness point. It found the definition, once its dictionary-defined terms and grammar were carefully parsed, gave clear enough notice of what counted as a truck stop, and the Owners never showed the definition was unclear as applied to their own specific QuikTrip plan. The Court agreed the earlier 1999 lawsuit did not bar the new case. It sent the case back to the superior court to decide whether the Board's decision was backed by enough evidence.

The Supreme Court of Georgia held that the UDO's 'truck stop' definition, properly construed using dictionary definitions and ordinary grammar rules, gave fair notice of what it prohibited and was not unconstitutionally vague, either as applied to the Owners' QuikTrip proposal or on its face.

The ruling means Rockdale County can keep enforcing its truck-stop ban while the permit fight continues, and it signals to Georgia local governments that zoning definitions survive vagueness challenges if courts can interpret them using dictionaries and grammar rules, even if imperfectly drafted.

Affirmed in part, reversed in part, and remanded; cross-appeal dismissed as moot

1. The court first addressed res judicata, a doctrine barring re-litigation of claims already decided between the same parties, and found the Owners' 1999 lawsuit over a different 'travel plaza' proposal under an earlier ordinance involved different facts and a different alleged wrong than this case, so it did not bar the new lawsuit.
2. The court explained that outside of free-speech cases, a vagueness challenge must first be tested against the specific facts of the case (an as-applied challenge) before a broader facial challenge can succeed, and the Owners' claim did not involve speech protected by the First Amendment.
3. Applying that framework, the court read the undefined terms in the 'truck stop' definition, such as 'maintenance' and 'servicing,' using their dictionary meanings and concluded ordinary readers could understand what conduct triggered the ban.
4. The court parsed the definition's use of 'and,' 'or,' and 'as well as' according to normal English grammar rules, concluding the ordinance required a business to meet multiple listed conditions rather than being hopelessly ambiguous about how many requirements applied.
5. Because the Owners never showed the definition was unclear as applied to their specific QuikTrip plan, and only raised hypothetical scenarios involving other property owners, their facial challenge to the ordinance also failed under Georgia's vagueness standard.
6. Having rejected both the res judicata argument and the vagueness challenge, the court sent the case back to the superior court to decide the remaining question of whether substantial evidence supported the Board of Adjustment's finding that the QuikTrip was in fact a truck stop.
