"Multicultural interlegality": This neologism is used primarily to refer to the process whereby local law yields to the superior force of a dominant national system and adopts many features of the majority law. It includes also a "reverse interlegality" where local legal sensibilities and practices in some respects affect the dominant law. This book includes contributions that analyze the legal position of the Roma/Gypsies/Travellers under state law in the UK and contextualizes this in terms of a general discussion of how Gypsy law interacts with state law among different groups of Gypsies in various parts of the world; examine measures for strengthening the autonomy of the Sámi in Norway; and give a Canadian example of reverse interlegality by showing how local Aboriginal justice affects non-Aboriginal national justice in the formal Canadian justice system through the channels of new institutions.
