This chapter undertakes a detailed examination of how R2P manifested in the Libyan case, engaging with some of the widely debated issues that permeate discussions on the conflict (most notably, on military intervention and regime change), as well as the more ‘under-researched’ aspects pertaining to R2P’s application within it. The specific angles examined within this chapter include Libya’s suspension from the UN Human Rights Council as well as the League of Arab States; the imposition of sanctions and an arms embargo by the UN Security Council; the referral of the Libyan situation to the International Criminal Court; the authorisation of the use of force by the UN Security Council; the limits, if any, that constrained military operations pursuant to this authorisation, with particular focus on regime change; and the role of rebuilding in the implementation of the Libyan R2P mandate.
