Stevenson challenged the result on the grounds of ballot stuffing alleged to have occurred in a single precinct, which involved 203 disputed votes from Jim Wells County. The Democratic State Central Committee sustained Johnson's apparent victory by a 29–28 vote. Stevenson was granted an injunction by the federal district court, which barred Johnson from the general election ballot. However, Supreme Court Associate Justice Hugo Black, sitting as a circuit justice, ruled that the federal district court lacked jurisdiction, and that the question was for the Central Committee to decide. He ordered the injunction stayed, and his ruling was upheld by the Supreme Court.
