This paper examines two significant Fourth Amendment issues: the Supreme Court's controversial ruling in Atwater v. City of Lago Vista (2001) and the doctrine of third-party consent to searches. The Atwater decision, criticized across the political spectrum, granted police authority to arrest individuals for fine-only traffic offenses, effectively removing probable cause requirements for minor vehicle stops and opening the door to potential abuse. The paper also analyzes how courts have defined "common authority" for third-party consent following United States v. Matlock (1974), tracing the judicial trend toward broader police search authority and reduced individual privacy rights.
The Supreme Court's decision in Atwater v. City of Lago Vista (2001) has been highly criticized by conservatives and liberals alike. Even for the most ardent law-and-order advocate, the fact that the Court ratified police authority to jail someone for a fine-only offense is troubling. The potential for abuse is significant: by allowing such arrests, police are now free to arrest and search any person and their vehicle on public streets and highways.
Atwater represented a further expansion of police authority regarding traffic stops and essentially opened the way for officers to arrest individuals for very minor offenses in order to investigate more serious crimes for which they would otherwise lack authority to arrest. The potential for abuse should be obvious — nearly every time a driver takes to the road, some minor traffic law is violated. Given the broad powers the Court afforded police in Atwater, any targeted individual whom police are anxious to apprehend can now be arrested and detained regardless of the minor nature of the alleged offense. In essence, the Atwater decision has removed the element of probable cause from the arrest and detention process, at least as it pertains to vehicle stops.
In light of the profound possibility for abuse following the Supreme Court's decision in Atwater, it is difficult to understand how the Court could have considered such a procedure "reasonable" as required by the Fourth Amendment. As argued in the strong dissent presented by Justice O'Connor, the majority's decision in Atwater was a "pointless indignity" that served no discernible state interest (Atwater, p. 360). In the final analysis, Atwater is bad case law that has expanded police authority beyond the limits of fairness and represents an infringement on the Fourth Amendment rights of every American citizen.
Traditionally, valid consent for a legal search can only be granted by the person being searched. Over the years, however, the right of a third party to consent to a search based on common authority or possession has been expanded. Whether a third party has the authority to grant consent depends on whether that person has sufficient legal authority over the place or thing the investigating authority seeks to search — that is, whether the person has "common authority."
