In the 3S mnemonic for Fourth Amendment applicability, what does the second 'S' represent?

• A. State Action
• B. Standing
• C. Search
• D. Seizure

Answer: (B)

The second S stands for Standing. After you establish that government action is involved (state action), the next question is whether the person bringing the claim has a legitimate privacy interest to challenge the search or seizure. Standing means you have a reasonable expectation of privacy in the place searched or the item seized. If you lack that privacy interest, you can’t invoke Fourth Amendment protections, even if the police did something unlawful to someone else’s property. For example, a homeowner has standing to challenge a search of their home; a mere visitor typically does not unless they share a privacy interest. The other pieces of the analysis (state action and what was searched or seized) come after determining standing.
