Available accounts on jurisdiction, effective control, and the reach of human rights protections fail to provide a coherent construction that is principled and applicable across the board, within and beyond territorial borders. The “functional jurisdiction” model posited herein resolves these incongruities by looking at the normative foundation of sovereign authority overall, predicated on an exercise of “public powers” through which State functions are discharged, taking the form of policy delivery and/or operational action, whether inland or offshore, and which translates into “situational” control. Using the pending case of S.S. and Others v. Italy as an illustration, the article focuses on the sovereign-authority nexus that unites a specific state with a specific individual in a specific situation, triggering human rights obligations even through mechanisms of “contactless control” exercised via remote management techniques and/or through a proxy third actor. The role of extraterritorial operations, qua complex mechanisms of governance that implement broader policies with a planning, rollout and post-implementation phase, is central to this re-conceptualization, as is also the understanding that what makes control “effective” is its capacity to determine the material course of events and the resulting position in which those affected find themselves upon execution of the measure(s) concerned
