The Riksdag Act contains detailed rules regarding the work procedures of the Riksdag. Until 1974 the Riksdag Act was a fundamental law but since then it has occupied an intermediate position between fundamental law and ordinary law.

The main provisions of the Riksdag Act can be amended by a single Riksdag decision taken by qualified majority - i.e. three-quarters of those voting and over half of the members of the Riksdag. It is more complicated to make amendments to a fundamental law.

The Riksdag Act is very comprehensive compared with corresponding regulations in other countries. For example, its fourteen chapters set how out meetings of the Chamber are to be conducted and what rules apply as regards the duties of the Speaker.

How proposals are submitted, considered and determined is also regulated in the Riksdag Act. One of the central chapters is that on the appointment and work procedures of the fifteen parliamentary committees.
