United States v. Ryan
731 F.3d 66
1st Cir.2013Background
- Ryan was stopped for crossing center line in Charlestown Navy Yard, within a federal enclave; arrest occurred after stop but outside officer's territorial authority; Ryan showed signs of intoxication and admitted drinking; he took field sobriety tests; he refused a breath test at the Park processing area; government charged federal offenses under 36 C.F.R. § 4.23 and related provisions; motion to suppress argued lack of statutory authority to arrest outside Park; magistrate and district court denied suppression; Ryan appeals the suppression ruling.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Fourth Amendment requires exclusion for evidence after extraterritorial arrest | Ryan (via LaMere) argues extraterritorial arrest violates Fourth Amendment. | LaMere's arrest supported by probable cause; exclusion not required. | No exclusion required; arrest did not violate Fourth Amendment. |
| Whether lack of arrest authority defeats constitutionality of arrest under Fourth Amendment | Lack of statutory authority makes the arrest unconstitutional. | Arrest can be constitutionally reasonable despite lack of authority. | Arrest remains constitutionally reasonable; evidence admissible. |
| Whether Moore controls whether extraterritorial arrests trigger suppression | Moore supports suppression when statutory violation occurred. | Moore applies; extraterritoriality not per se suppression. | Moore guides result but here lacks per se suppression for extraterritorial arrest. |
| Impact of territorial limits on officer's discretion under Fourth Amendment | Territorial limits should trigger suppression of evidence. | Territorial limits do not automatically render the arrest unconstitutional. | Extraterritorial arrest not per se unreasonable; no suppression. |
