Under what circumstances can legal representation be requested according to the Sixth Amendment?

The Sixth Amendment to the United States Constitution guarantees the right to counsel for defendants in criminal prosecutions. This right is not limited to a particular stage of the criminal process; rather, it extends to any point during criminal proceedings. This means that individuals are entitled to legal representation throughout the entire process, starting from the initial custodial interrogation, during pre-trial stages, throughout the trial, and including sentencing and any appeals that may follow.

The flexibility of the right to counsel ensures that defendants have access to legal advice and representation at crucial points where their rights could be affected, ensuring a fair trial and upholding the integrity of the judicial process.
