ICT is important for legal work. Digitalization, legal databases and the Internet are essential requisites. We have only seen the beginning – the evolution of the information society is a self-sustained process and potentialities for rationalisation in the legal domain are substantial. Practically this entails research in the forefront of artificial intelligence, embedded legislation and automated decision making. Preservation of basic legal principles, standardisation and quality assurance are crucial. Advancements in this direction often challenge established legal theory, traditional legal culture and mind-sets. In order to develop a theoretical framework for advanced methods and legitimate tools, it is thus also important to analyse the underlying functions of the law, its objectives and limitations.
