The length of time that someone can be held in jail can vary depending on the jurisdiction and the case circumstances. In general, the length of time that someone can be held in prison is governed by legal rules and procedures designed to protect the rights of the accused and ensure that justice is served.

In the United States, the Fifth Amendment to the Constitution provides that no person shall be deprived of liberty without due process of law. This means that anyone arrested and detained must be afforded certain legal protections, including the right to a speedy trial and the right to be free from unreasonable searches and seizures.

In practice, the length of time that someone can be held in jail before trial or sentencing can vary widely depending on the jurisdiction and the case’s specifics. In some cases, a person may be held for only a few hours or days before being released or formally charged with a crime. In other cases, a person may be held for several months or even years while awaiting trial or sentencing.

The length of time that someone can be held in jail may be influenced by various factors, such as the severity of the alleged crime, the defendant’s criminal history, and the availability of evidence and witnesses.
