On the Right to Diplomacy: Historicizing and Theorizing Delegation and Exclusion at the United Nations

COSTAS M. CONSTANTINOU and FIONA MCCONNELL analyse the disregarded notion of the ius legationis (right of legation), revisiting historical debates in diplomatic theory and law over who possesses or ought to have this right. 
“By examining how the ius legationis manifested into a volitional or subjectional or natural right, we argue that this renders it not merely a legal issue, but a highly political and ethical question that is of direct relevance to contemporary international relations,” the authors write in ‘On the right to diplomacy: historicizing and theorizing delegation and exclusion at the United Nations’, published in the journal International Theory.
In an era where inclusivity is rhetorically promoted at the United Nations, the authors suggest that a rekindled right to diplomacy (R2D) – conceiving diplomacy as a right that is claimed but also contested – can shed light onto inequalities of representation and the role international law can play in remedying asymmetries and ethicizing the practice of diplomacy. 
Beyond its primary normative contribution, CONSTANTINOU and MCCONNELL argue that the R2D can also provide an analytical framework to understand UN’s efforts at institutionalizing diplomatic pluralism, its logics of inclusion and exclusion, as well as the struggles of diverse groups to obtain accreditation, consultative status, and negotiation ability within multilateral diplomacy.
