Overview

In a paper by the Harvard Law School Program on International Law and Armed Conflict (HLS PILAC) titled “Quantum of Silence: Inaction and Jus ad Bellum” (2019), Dustin A. Lewis, Naz K. Modirzadeh, and Gabriella Blum examine the actual and potential roles of silence in the identification and the development of international law, with a focus on the legal regime governing the threat or use of force in international relations.

The analysis in the paper is complemented with an annex — to which a team of HLS PILAC research assistants contributed — that contains the most comprehensive catalogue to date of apparent self-defense reports to the Security Council under article 51 of the U.N. Charter. Those contributors were Lindsay Anne Bailey, Emma Broches, Laura Clark, Sonia Chakrabarty, Thejasa Jayachandran, Daniel Levine-Spound, Sarah Libowsky, Samantha Lint, Yang Liu, Carolina Silva-Portero, Shira Shamir, William Ossoff, Tamsin Parzen, and Shanelle Van.

The paper and catalogue arose out of the HLS PILAC research project titled “Self-defense, States’ Silence, and the Security Council.”
