A Dallas, Texas, city ordinance restricted admission to so-called Class E dance halls to persons between the ages of 14 and 18. The ordinance did not impose similar age limitations on most other establishments where teenagers might congregate for ex, skating rinks. Charles Stanglin, who in one building operated both a Class E dance hall and a roller-skating rink, filed suit in a Texas trial court in an effort to obtain an injunction against enforcement of the ordinance. He argued that the ordinance violated the U.S. Constitutions Equal Protection Clause. The trial court rejected Stanglins argument, but a Texas appellate court struck down the age restriction. The U.S. Supreme Court agreed to decide the case.

Did the age restriction in the Dallas ordinance violate the Equal Protection Clause?
