What happens if magistrate refuses to issue arrest warrant for person in custody due to lack of probable cause?

• A. Officer may be sued for false arrest
• B. Officer can request commonwealth attorney to request a warrant from judge
• C. Officer must release suspect
• D. The suspect is detained without charges

Answer: (C)

When there is no probable cause for an arrest, the person cannot be lawfully detained. The magistrate reviews the officer’s evidence and, if it fails to show probable cause, will not issue an arrest warrant. In that situation, the officer must release the suspect because there is no legal basis to hold them. Context helps: the Fourth Amendment protection against unreasonable seizures hinges on probable cause. If the magistrate denies the warrant, any continued detention would lack a lawful justification, so release is required. The officer could later reconvene or re-present stronger evidence to obtain a warrant from a judge, but that would happen only if probable cause is shown. Why the other ideas don’t fit: a claim of false arrest isn’t triggered by a denied warrant if no arrest actually occurred; the inability to obtain a warrant isn’t itself a basis to sue for false arrest. Reaching out to the commonwealth attorney to pursue a warrant from a judge would only make sense if there’s probable cause to present; without it, the judge is unlikely to issue one, and the immediate outcome remains release. Detention without charges would be improper once probable cause is lacking.
