A modern society is often characterized by a large measure of welfare that all citizens take part of to a greater or lesser extent. Welfare can be defined as the social rights and benefits enjoyed by the habitants of a country. In Sweden, the social safety net is well developed and offers financial compensation in several situations and the individual can safely rely on the social safety net. In addition, legislations and insurances have been developed to offer protection to the habitants in special deserving cases. For example, when a person gets injured at the work-place or in traffic there are insurances that allow compensation regardless of any negligence, so called culpa. The insurance form is called no fault insurances. In addition, there is tort law that is applicable on all non-contractual damages.

Further on the motives to the regulations will be examined, followed by cases illustrating the actual application and specialness of the regulations.
