Four Cobb County students with disabilities challenged the school district’s COVID-era policy prohibiting schools from requiring masks. The Eleventh Circuit held that two students who had later left the district still had standing because they had shown a sufficient threat of concrete future injury at the start of the litigation. But the court affirmed the denial of a preliminary injunction for the two students who remained enrolled, concluding that the district’s individualized accommodations were largely effective and that the students had not shown a substantial likelihood of success on their failure-to-accommodate claims under Title II of the Americans with Disabilities Act and Section 504 of the Rehabilitation Act.
