Under the Constitution of Finland, everyone is entitled to have their case heard by a court or an authority appropriately and without undue delay. This is achieved through the judicial system of Finland.

The Constitution of Finland is the supreme source of national law of Finland. It defines the basis, structures and organisation of government, the relationship between the different constitutional organs, and lays out the fundamental rights of Finnish citizens, and individuals in general. The original Constitution Act was enacted in 1919, soon after Finland declared its independence in 1917. The current draft of the Constitution came into force on 1 March 2000.
