A group of Athens bars and onetime bar employees dropped a suit challenging the constitutionality of a law forbidding anyone under the age of 21 from entering or working in a bar.

The suit was dismissed with prejudice in the wake of a June opinion by the Georgia Supreme Court that effectively barred any lawsuits challenging the enforcement of purportedly unconstitutional laws. The Athens Association for Constitutional Rights, a coalition of five bars, joined three individual plaintiffs who worked as bartenders, doormen and barbacks before they were fired last year after Gov. Nathan Deal signed “Michael’s Law” into effect.
