If someone was denied bail what amendment could they site to make an argument for bail?

If someone was denied bail, they could cite the Eighth Amendment to the U.S. Constitution, which prohibits excessive bail and cruel and unusual punishment. They might argue that the denial of bail constitutes an excessive punishment that is disproportionate to the charges against them. Additionally, they could reference the Due Process Clause of the Fourteenth Amendment to argue that their right to a fair trial is being compromised by the inability to secure release before trial.
