In the case of Michigan v. Mosley, the U.S. Supreme Court ruled in favor of police officers who had interrogated a suspect multiple times after he initially invoked his right to remain silent during an interrogation about a robbery. The court held that there was no violation of Miranda rights as long as they "scrupulously honored" the defendant's decision to cut off questioning for some time and only resumed it on a different crime subject matter later on with fresh Miranda warnings given again. This ruling clarified that law enforcement could re-approach and question suspects even after they have asserted their right to silence, provided certain conditions are met such as honoring initial invocation, providing adequate interval before resuming questioning and giving new set of warnings.

In the dissenting opinion for Michigan v. Mosley, Justice Marshall argued that the majority's decision undermined the protections provided by Miranda rights. He contended that once a suspect has invoked their right to remain silent, police should not be allowed to resume questioning unless an attorney is present or there is clear evidence of new circumstances justifying further interrogation. According to him, allowing re-interrogation after a significant time gap and on different crimes still violated suspects' Fifth Amendment rights against self-incrimination as it could lead to coercion and involuntary confessions. This approach would also create confusion among law enforcement officers about when they can resume questioning without violating constitutional rights.
