What significant legal standard was addressed in Maryland v Shatzer?

In the case of Maryland v. Shatzer, the Supreme Court established that a suspect's right to counsel under Miranda can be revisited after a break in custody. This principle stems from the idea that if a suspect has been released from custody and is not subjected to continuous interrogation, they may have a set period during which they can reset their Miranda rights upon being taken into custody again.

The Court held that a suspect's prior invocation of the right to counsel does not persist indefinitely, particularly if there is a significant break in time and circumstances between the two custodial interrogations. In Shatzer's case, the substantial time lapse and the fact that the suspect was out of custody for over two years allowed the Court to rule that he could be questioned again without having the previous waiver carry over.

This ruling clarifies the limits of how long a suspect's rights under Miranda can endure and establishes that a change in circumstances can effectively "reset" these rights. Such an understanding is vital for law enforcement officers to know, as it impacts the procedures they must follow when resuming questioning after a prior invocation of rights.
