What does a 'double lock' mean in English law?

• A. Warrant valid for 24 hours
• B. Warrant applies only to digital search
• C. Warrant requires two signatories
• D. Warrant to search the house can be given by two people

Answer: (C)

Double lock means two independent signatories are required to issue a warrant to search. This is a safeguard in English law: no single officer can authorize a search of a home or private premises—the warrant must be approved by two magistrates, providing a check against abuse of power. It isn’t about a 24-hour limit or about digital versus physical searches, and it isn’t simply about two people giving the warrant—the crucial point is that two separate, independent approvals are required.
