In general, the Nordic legal model is seen as half-way between common law and civil law legal traditions. There has never been a codification of all laws in Sweden (the last code drafted in 1736 was a compilation of existing laws) while at the same time, certain areas of law rely heavily on case law. The Swedish legislative technique has been to enact fairly general laws with little detail. The court then turns to the legislative preparatory works when interpreting the laws to help fill in the lack of detail. This lack of detail in labour and employment law is supplied instead by the collective agreements first, then the legislative preparatory works.
