In the ongoing discussion regarding the governance model for the Arctic, references to commonality are a salient feature. Made both by Arctic and non-Arctic States, these references are meant to support demands for either a more exclusive, i.e. Arctic, or a more inclusive, i.e. international model of cooperation. The purpose of this paper is to outline the various forms of these references to commonality, investigate their intended meaning and assess their legal implications (or lack thereof) for both Arctic and non-Arctic States. This analysis allows for the drawing of some tentative conclusions regarding the underlying motivations that drive these references as well as the hidden politico-legal preferences at play. It also provides the opportunity to reflect on the broader issue of the legal parameters that need to be respected in devising a new governance model for the Arctic.
