The research project aims to investigate whether and how the role of the Supreme Court (SC) in the Swedish legal system has changed over the last fifty years. In the past, the Supreme Court was seen primarily as a second court, deciding cases as a third instance. More recently, however, the Court's function has shifted to focus more on guiding the application of the law and acting as a precedent setter. Constitutional provisions and issues are also now more common and important in the Supreme Court, which for some may be perceived as a shift of power from political to judicial institutions. The research team behind the project wants to systematically examine these changes by analyzing the jurisprudence of the Supreme Court, the role of the justices (judges) within the Supreme Court, and the relationship of the Supreme Court to the political institutions and to the other courts. Among other things, the project will explore the relationship between the Supreme Court and political institutions, as well as analyze how individual judges have influenced and influence the development of the law. They have created a unique database of over 2000 cases from the period 1981-2022, allowing a deeper understanding of how the Supreme Court and its function in the legal system have evolved. Through its results, the project will contribute to a deeper understanding of how the Supreme Court functions and changes, but by extension also of the legal system in general. This knowledge is crucial for understanding the balance between legal and political power in society and is of both national and international interest.
