The ruling upholds a broad right to be free from unreasonable searches. But it also highlights a struggle within the Supreme Court to balance law enforcement objectives with privacy concerns.
Law enforcement officials must obtain a court-authorized warrant before using a GPS device to track the movements of a criminal suspect’s vehicle, the US Supreme Court ruled on Monday, eliciting praise from privacy advocates.
In a unanimous decision, the high court said Fourth Amendment guarantees against unreasonable searches prohibit police or federal agents from affixing a Global-Positioning-System (GPS) tracking device to a private vehicle and then recording the vehicle’s every movement 24 hours a day for weeks or months without prior court approval.
The decision is a setback for the Obama Justice Department, which had argued that the Constitution did not hinder its use of tracking technology to monitor vehicles traveling on public streets.
The opinion in US v. Jones (10-1259) is important because it upholds a broad right to be free from unreasonable searches. But it also highlights an emerging struggle within the high court to establish a consistent method of analysis that properly balances law enforcement objectives with privacy concerns.
As the government deploys an increasingly sophisticated and intrusive repertoire of surveillance technologies, privacy advocates warn that zones of privacy are fast shrinking in America.
“We have entered a new and frightening age when advancing technology is erasing the Fourth Amendment,” said John Whitehead, president of the Virginia-based non-profit Rutherford Institute, in a statement.
