Sweden is a parliamentary democracy. In the Swedish legal system, it is the Riksdag that is the main standard-setter, and it is the Riksdag that controls the actual standard-setting power. However, norms of importance to Sweden are not only found in the internal legal order. Sweden has entered into a large number of international agreements - treaties - which it is obliged to follow under international law. Some treaties must be approved by the Riksdag, but treaty-making power rests with the government. A significant part of treaty-making power has also been transferred to the EU. And in the EU context, it is usually the government that represents Sweden. As Sweden becomes involved in more and more international cooperation, there is thus a risk of a significant shift in power from the Riksdag to the government and the EU. This is a democratic problem, which is important to study and understand. The aim of this project is to increase knowledge about the relationship between the Riksdag and treaty power. The project will study how the legislative power of the Riksdag is affected when the treaty power is exercised, and how mechanisms for the Riksdag's control and influence over the treaty power are constructed.
