Consent to search must be based on which concept?

• A. Probable cause
• B. Actual control or apparent authority
• C. Custody and interrogation
• D. Warrant or subpoena

Answer: (B)

Consent to search works only when the person giving permission has real control or authority over the area or item being searched. That means either they actually own or manage the space, or they have legitimate shared authority that would lead a reasonable person to believe they can permit access. If someone lacks that control or authority, their consent cannot authorize a search of the space or items beyond what they’re allowed to permit.

This is why the idea hinges on actual control or apparent authority: it protects the integrity of the Fourth Amendment by ensuring that only someone who legitimately has the power to grant access can authorize a search. Probable cause, custody and interrogation, or a warrant/subpoena operate in different contexts—probable cause is about justification when consent isn’t given, custody/interrogation relates to Miranda rights, and warrants or subpoenas are alternative routes to search when consent isn’t used.
