The workshop aims at integrating a number of topics linking legal and ethical questions raised by the practice of humanitarian aid increasingly at the forefront of recent academic debates as a result of late 20th century historical incidents worldwide that have made humanitarian aid a controversial issue both in theory and in practice. Humanitarian aid can assume a variety of forms and means, including military intervention, and may take on a multifarious array of, both wide and narrow, purposes legitimizing it as ‘humanitarian’. One of the central characteristics of this topic making it important is that its peculiar and multiple aspects bring together a multitude of questions in the legal philosophical field that need to be clearly delineated and possible wrong relationships cleared out. In this sense, it is a topic that brings forth at its most poignant the relation between Law and Ethics.
