Procedural and arbitration law deals with the forms of judicial and arbitral proceedings in various types of criminal and civil cases. The regulation of procedures and processes within different judicial bodies is of central importance to a democratic society and a guarantee of people's right to legal certainty and security.

The subject of procedural law deals with the ways in which the courts administer justice in criminal, property and family cases. Important areas of general procedural law include, for example, procedural bars, forum, pleading, cumulation, precautionary measures, coercive measures, res judicata, costs, evidence, and the evaluation of evidence. In addition, there are the various stages of the trial itself, such as the preparation, main hearing and judgment in civil cases and the preliminary investigation, indictment, main hearing and judgment in criminal cases.

Arbitration law deals in particular with the rules of procedure for arbitration panels - i.e. the dispute resolution bodies that can settle disputes in which a settlement can be reached instead of a court. The starting point is the Swedish Arbitration Act, but as the subject is highly topical at the international level, the UNCITRAL Model Law, the New York Convention and various arbitration rules are added. Issues covered include the conclusion and interpretation of the arbitration agreement, the relationship with the court process, the mandate of the arbitrator, the conduct of arbitration proceedings, the rules on challenges and invalidity, institutional procedures and enforcement issues.
