The existing Polish Constitution, enacted in 1997, divides the sources of law into two types: universally and internal binding. This is the first time such a division has been made in the history of the current Republic of Poland. The Constitution formulates the concepts of internal laws, binding only those parties that are intrinsic to the body that issues such laws. These laws function only within the hierarchical framework of the intrinsic parties and cannot serve as a basis for decisions taken in respect to citizens, legal persons and other external parties.
