In the case of Cox v. Cook, 1974, the United States Supreme Court addressed a dispute involving prison disciplinary procedures. The petitioner was an inmate in Virginia who had been disciplined for violating prison rules without being given a hearing or any other form of due process. He filed suit against officials from the Virginia Division of Corrections, arguing that his constitutional rights were violated by this lack of procedural safeguards. The Supreme Court held that while prisoners do have certain basic rights under the Constitution, these are subject to limitations and restrictions necessary for maintaining order and security within correctional institutions. Therefore, it ruled in favor of corrections officials stating they did not violate prisoner's constitutional rights when disciplining him without providing a formal hearing or similar procedural protections.

In the dissenting opinion for Cox v. Cook, Justice William O. Douglas argued that the majority's decision to uphold a Virginia law prohibiting prisoners from assisting each other with legal matters was unconstitutional and violated their First Amendment rights. He contended that such assistance is vital in ensuring inmates have access to justice, particularly those who cannot afford an attorney or are illiterate. Furthermore, he believed this prohibition could potentially lead to more instances of injustice within prisons as it would limit inmates' ability to challenge unlawful practices or conditions effectively. In his view, allowing prisoner-to-prisoner legal assistance could help alleviate some of these issues by providing a means for less privileged inmates to navigate complex legal processes and advocate for their rights.
