In the case of Dixon v. Duffy, Warden in 1951, the petitioner, Dixon was convicted for first-degree murder and sentenced to death by a California court. The Supreme Court granted certiorari to review whether or not his constitutional rights were violated during his trial. Specifically, it was argued that he did not have effective counsel as guaranteed by the Sixth Amendment because his attorney had been appointed only two days before trial and had little time to prepare a defense strategy. Furthermore, there were allegations that evidence used against him at trial was obtained through an illegal search and seizure which would violate Fourth Amendment protections if true. The Supreme Court ruled in favor of Dixon stating that due process requires adequate time for preparation of defense irrespective of state laws or practices; thus remanding the case back to lower courts for further proceedings consistent with this opinion.

In the dissenting opinion for Dixon v. Duffy, it was argued that the majority's decision to deny habeas corpus relief to a state prisoner who had been denied counsel during his trial violated basic principles of fairness and justice. The dissenting justices believed that every defendant, regardless of their ability to pay, should have access to legal representation in order to ensure a fair trial. They contended that denying this right could lead to wrongful convictions and undermine public confidence in the judicial system. Furthermore, they expressed concern about potential abuses of power by prosecutors and judges if defendants were not adequately represented in court proceedings.
