A trip to Lomonosov Ridge: the Arctic, UNCLOS and ‘off the shelf’ sovereignty claims 
CHRISTOPHER MARK MACNEILL
University of Ottawa

This Article explores the substantive merit of Russia’s sovereignty claims over the extension of its 200 nautical mile continental shelf limit via the Lomonosov Ridge to include an additional 150 nautical miles reaching almost to the North Pole. In particular, the issue is whether Russia’s claims are justified and what legal premises support its position. In view of counter claims by Canada, Denmark (Greenland), and the littoral states in the region, this Article also attempts to identify the inherent conflict within the competing sovereignty claims and potential alternatives for amicably resolving an appropriate international legal framework for the region.

Land use planning in Britain: a problem of law and economics 
JOHN CORKINDALE
Kingston University 
British planning law and practice has been remarkably resistant to economic evaluation. Official guidance in the UK on how to do economic evaluation generally indicates that the essential first steps are to define the rationale and objectives of the policy or project under consideration. Yet it is precisely these first steps that the attempts that have been made to conduct an economic evaluation of British land use planning have found difficult to take. This article uses a inter disciplinary perspective to considers the history and limitations of evaluating planning law and practice in the UK.
