This case study aims to introduce and investigate Protocol as a Functional Area at International Sports Events. It explores the definition of the word ‘protocol’, breaking down the meaning in both sporting and non-sporting, event and non-event contexts. It focuses particularly on the multiple layers of protocol that exist at Major International Sports Events, from Diplomatic Protocol to Rights-Holders of the Event prescribed Protocol, and on how stakeholders specific to each event can also influence procedures. In the case of conflict it examines which protocol and customs take priority.
