A Michigan search warrant may be subject to challenge if it lacks probable cause, contains false information or fails to identify the place or items to be searched with sufficient particularity. Police must also follow the required procedures when obtaining and executing the warrant. These defects may give rise to a motion to suppress the evidence, which could significantly weaken the prosecution’s case.
When can the information supporting a search warrant be challenged?
The warrant must be based on facts that establish probable cause. The search warrant affidavit should explain why police believe a crime occurred or why evidence may be found at the listed location. Insufficient facts may leave the warrant open to challenge. Missing or false details can also affect its validity. If an officer knowingly or recklessly includes false information in the affidavit, that information could support a motion to suppress the evidence obtained. Police must gather supporting evidence through lawful means.
Evidence from an illegal entry, trespass or eavesdropping may not support probable cause. Old information can also weaken a warrant. A long delay between the suspected crime and the search may make it less likely that evidence remains at the location. Confidential and anonymous sources also need support. The affidavit should show why the source is reliable and explain how the source learned the information, such as through something the source saw, heard or did.
Warrant defects and execution problems that can make a search unlawful
A valid warrant should clearly identify the place police may search and the property they may seize. A vague or overly broad warrant may face a legal challenge.
Police generally must have a signed warrant before starting a search. Michigan law also allows electronic warrants in some cases. Officers must follow the warrant’s terms and stay within its limits. A search that goes beyond those limits may give the defense grounds to seek suppression of the evidence.
Key points to review include:
- Particularity: The warrant should describe the place to be searched and the persons or things to be seized with sufficient specificity.
- Signed warrant: Police should have the signed warrant before the search begins.
- Scope: Officers should stay within the limits set by the warrant.
These concerns differ from problems with obtaining the warrant. Issues with probable cause or the affidavit may affect how the warrant was issued. Improper execution may involve police failing to follow the terms of an otherwise valid warrant.
Defend against invalid searches
Evidence uncovered during an illegal search can directly threaten a person’s freedom. If police violate Michigan’s warrant rules, the exclusionary rule may bar that evidence at trial and weaken the prosecution’s case. Early review can uncover flaws while the details of the search are still fresh and well-documented. A Michigan criminal defense attorney can assess the warrant, affidavit and search to determine whether a challenge may succeed.
