It is today evident that the European Convention on Human Rights (ECHR) has had a fundamental impact on the Swedish legal order as a whole, including constitutional and administrative law. Perhaps the most important change is the understanding of individual rights in the Swedish legal order. Swedish courts are today more frequently and with greater self-esteem upholding fundamental rights based in the Swedish constitution, the ECHR and EU law. This development has, however, been neither linear nor without friction. With regard to general administrative law the impact can be described as patchy. Some areas have undergone radical changes, where longstanding traditions of Swedish administrative law have been abandoned, whereas other areas have remained more or less intact. The main conclusion of this chapter is thus that the impact of the ECHR and other Council of Europe (CoE) instruments has been undeniable but partial, and to a certain extent hidden.
