Space law is an area of International Law that has developed massively in the last fifty years. Francis Lyall, Emeritus Professor of Public Law at the University of Aberdeen, Scotland, and Paul B. Larsen, Adjunct Professor at Georgetown Law Centre, Washington DC, and formerly lawyer for the Office of the US Secretary of Transportation, have been involved with it since their days at the Institute of Air and Space Law, McGill University, Montreal, in 1963-4 and both teach Space Law at their respective Universities. This book gathers together their experience in readable form, and, with an extensive citation of the literature of space law, its discussion provides an excellent source for both student and practitioners.
