Why did the US supreme court agree to hear gideons case?

The U.S. Supreme Court agreed to hear Gideon's case because it raised significant questions about the right to counsel under the Sixth Amendment. Gideon argued that he was denied a fair trial when he could not afford an attorney, which challenged the existing interpretation that the right to counsel only applied in federal cases. The Court recognized the importance of ensuring that all defendants, regardless of their financial situation, have access to legal representation to ensure fair trials. Ultimately, this case led to the landmark decision in Gideon v. Wainwright, which extended the right to free legal counsel to state courts.
