Kudos to Professor Renee Hutchins, whose article, "Tied Up in Knotts? GPS Technology and the Fourth Amendment," 55 UCLA Law Review 409 (2007) was cited by and played in crucial role in the D.C. Circuit Court's recent opinion in
U.S. v. Maynard (2010). Professor Hutchins in that article distinguished Global Positioning System (GPS) devices from the beeper that the Supreme Court of the United States in
United States v. Knotts ruled could be placed in a suspect's car without a search warrant. Her careful doctrinal analysis established a difference between a beeper which monitored a single trip and a GPS device that would tell government authorities where suspects drove their cars for an extended period of time. We may not have a reasonable expectation of privacy when we are on the road, but most people think the police ought not keep a record of every car trip they take. The D.C. Circuit endorsed Professor Hutchin's important scholarly analysis. When ruling that the police violated a suspect's fourth amendment rights by installing a GPS device in his car for four weeks, Justice Douglas Ginsburg's unanimous opinion quoted the central contention of Professor Hutchin's paper. "According to the Supreme Court," the cited passage from that article declared, "its decision [in
Knotts] should not be read to sanction 'twenty-four hour surveillance of any citizen of this country." The
Maynard opinion later cited Professor Hutchins a second time on the precise technology used by GPS devices. Another example of the remarkable influence of one of the most promising young professors at the University of Maryland School of Law.
