Today, legal transplants are often mentioned in the broader process of
diffusion of law or
legal acculturation. J.W. Powell is credited with coining the word “acculturation”, first using it in an 1880 report by the US Bureau of American
Ethnography. He explained that this term refers to the
psychological changes induced by
cross-cultural imitation. In a broader context, such notion is by many contemporary scholars applied to legal thought. The diffusion of law is a process of legal change in today’s age of
globalization. Studies on diffusion of law are notably a new area of research in the 21st century. In 1998,
Gunther Teubner expanded the notion of legal transplantation, introducing the concept of
legal irritation: Rather than smoothly integrating into domestic legal systems, a foreign rule disrupts established norms and societal arrangements. This disruption sparks an evolution where the external rule's meaning is redefined and where significant transformations within the internal context are triggered. Lasse Schuldt added that irritation is not spontaneous, but requires institutional drivers. As an example, Schuldt points to the introduction of
corporate criminal liability in Thailand (a concept originally stemming from
English law), which was driven by pivotal decisions of the
Supreme Court of Thailand. ==References==
