The Michigan Supreme Court ruled on July 30, 2026, that statements made by a suspect while detained in violation of the Fourth Amendment must be excluded from evidence unless the prosecution can prove that the statements were sufficiently attenuated from the unlawful conduct. This decision came from the case People v. Sanders, Docket No. 167899, and it has significant implications for how evidence is handled in criminal cases involving unlawful detentions.
The ruling affects defendants in criminal cases, particularly those who have been detained without a proper judicial determination of probable cause. The court's decision emphasizes the importance of protecting individuals' rights against unreasonable searches and seizures, a fundamental principle enshrined in the Fourth Amendment of the U.S. Constitution.
In this case, John H. Sanders was convicted in 2013 of felony murder and first-degree child abuse after his three-month-old daughter died from a traumatic brain injury. Sanders took his daughter to the hospital after she stopped breathing, and while she was in critical condition, he was interrogated by police. After initially denying responsibility, Sanders made several incriminating statements, including that he shook his daughter when she would not stop crying. However, he was detained for over 64 hours without a judicial determination of probable cause before making those statements.
The case reached the Michigan Supreme Court after Sanders filed a motion for relief from judgment in 2019. The trial court had granted a new trial based on ineffective assistance of counsel, but the prosecution sought to admit Sanders's statements made during the unlawful detention. The trial court initially allowed the statements, concluding they were voluntary, despite the Fourth Amendment violation. Sanders appealed, leading to the Supreme Court's review.
In its ruling, the Michigan Supreme Court, led by Justice Kyra H. Bolden, stated, "Statements made by a detained arrestee while seized in violation of the Fourth Amendment’s requirement of a prompt judicial determination of probable cause must be excluded from evidence unless the prosecution establishes that the statements were sufficiently attenuated from the taint of the unconstitutional conduct." The court emphasized the need for a thorough analysis of whether the statements were made under coercive circumstances and whether the police misconduct was flagrant.
The court's opinion also clarified that the voluntariness of the statements is a separate inquiry that must be considered alongside the Fourth Amendment violation. The ruling vacated the trial court's order allowing the prosecution to use Sanders's statements and remanded the case for further proceedings to apply the appropriate standards.
This ruling has significant implications for future cases involving unlawful detentions and the admissibility of evidence obtained during such detentions. It reinforces the necessity for law enforcement to adhere to constitutional protections when detaining suspects and interrogating them. The ruling aims to deter police misconduct by ensuring that evidence obtained through unconstitutional means is not used in court.
Going forward, this decision may affect how courts handle similar cases where defendants claim their Fourth Amendment rights have been violated. It sets a precedent that could lead to the exclusion of critical evidence in cases where suspects have been unlawfully detained, thereby impacting the outcomes of trials and the overall justice process.
The case may also be subject to further legal challenges or appeals, as the implications of the ruling could prompt additional scrutiny of police practices and the handling of evidence in criminal cases. Legal experts and advocates for criminal justice reform will likely monitor the fallout from this decision closely.
