Basic Laws of Sweden
The Basic Laws of Sweden (Swedish: Sveriges grundlagar) are the four constitutional laws of the Kingdom of Sweden that regulate the Swedish political system, acting in a similar manner to the constitutions of most countries.
These fours laws are: the Instrument of Government (Swedish: Regeringsformen), the Freedom of the Press Act (Swedish: Tryckfrihetsförordningen), the Fundamental Law on Freedom of Expression (Swedish: Yttrandefrihetsgrundlagen) and the Act of Succession (Swedish: Successionsordningen). Together, they constitute a basic framework that stands above other laws and regulation, and also define which agreements are themselves above normal Swedish law.
The Parliament Act (Swedish: Riksdagsordningen) is usually considered to be halfway between a fundamental law and a normal law, with certain main chapters afforded similar protections as the fundamental laws while other additional chapters require only a simple parliamentary majority.
To amend or to revise a fundamental law, the Riksdag needs to approve the changes twice in two successive terms with qualified majorities, with a general election having been held in between. The first vote can be replaced with a referendum.
