WilmerHale Senior Associate Daniel Costelloe, a London-based member of the International Arbitration Group, has been awarded the 2016 International and Comparative Law Quarterly (ICLQ) Young Scholar Prize for his article "Treaty Succession in Annexed Territory."

The prize is awarded annually to the best article by a scholar aged 35 or under. It is supported by Cambridge University Press, which publishes ICLQ.

Costelloe's article explores the question of whether the territorial application of a treaty extends to unlawfully annexed territory. The article concludes that, while in some cases there is scope to find that a treaty applies extraterritorially in annexed territory, notably as a result of its object and purpose or its provisions, there may also be room, subject to the provisions of the treaty, for a limited form of treaty succession in such territory.
