129 CARPENTER V. UNITED STATES: STATE SURVEILLANCE AND CITIZEN PRIVACY Nehaa Chaudhari and Smitha Krishna Prasad * ABSTRACT The technological possibility of tracking a mobile phone's location with increasing accuracy coupled with the ubiquity of phones make it possible to track the location of a mobile phone user with considerable accuracy. This increases the potential for intrusive surveillance. This comment analyses the constitutional safeguards against the tracking of such data by the State. First, it reviews the case Timothy Ivory Carpenter v. United States, a United States (“US”) judgment on the power of the State vis-à-vis the citizen's right to privacy. Second, it compares the principles evolved in the US with Indian jurisprudence. Lastly, the comment observes that, despite certain problematic principles from US jurisprudence being eschewed by the Indian Supreme Court, there continues to exist concerns regarding the overreach of State power through Indian statutory provisions and other loopholes that haven't yet been scrutinized from the perspective of the right to privacy. * Nehaa Chaudhari is Public Policy Lead at Ikigai Law, an award winning policy and law firm focused on emerging technologies.
