 Although Afroyim had later acquired Israeli citizenship and voted in at least two other elections in his new country, his lawyers were able to avoid discussing this matter and instead focus entirely on whether foreign voting was a sufficient cause for loss of one's U.S. citizenship.The Supreme Court ruled in Afroyim's favor in a 5–4 decision issued on May 29, 1967.The opinion of the Court—written by Associate Justice Hugo Black, and joined by Chief Justice Warren and Associate Justices William O. Douglas and Abe Fortas—as well as Associate Justice Brennan, who had been part of the majority in "Perez"—was grounded in the reasoning Warren had used nine years earlier in his "Perez" dissent.
