F.A. Mann is considered to be one of the finest British lawyers of the twentieth century, esteemed as an international jurist and as a practising solicitor. He combined a thriving and prestigious practice with a prolific output of writing and teaching, with much of his work centering on the inter-relationship of international and national law. This collection, first published in 1990, brings together seventeen of his essays and continues where the author's previous volume, Studies in International Law (OUP), left off in 1963. Topics covered include investment, arbitration, jurisdiction, and recognition of States.
