The Role of Polish Courts in the Development of International Law after Regaining Independence by Poland in 1918

The article explores the question to what extent Polish courts could have contributed to the development of international law between the two World Wars, after Poland regained independence in 1918 and began rebuilding the State. This is also a period when the practice of national courts was particularly important for the elaboration of general standards of conduct in numerous areas of international law. Many of the decisions of Polish courts, especially those that concern the consequences of succession of States, the occupation of enemy territory, nationality and statelessness, diplomatic and State immunities or effects of the treaties were relevant in this process.
