Poland: International Team Project

This guide is designed to accompany the ITP: Poland course for Spring 2020. It is also of general interest to anyone interested in researching Polish law and legal institutions.


In addition to researching the national (domestic) law of Poland you will need to also research Poland's obligations under international law.

Article 38 of the Statute of the International Court of Justice sets out the sources of international law:

The Court, whose function is to decide in accordance with international law such disputes as are submitted to it, shall apply:

a. international conventions, whether general or particular, establishing rules expressly recognized by the contesting states;

b. international custom, as evidence of a general practice accepted as law;

c. the general principles of law recognized by civilized nations;

d. subject to the provisions of Article 59, judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.

The most important source of international law are international conventions, also known as treaties or international agreements. This guide will provide information on finding treaties where Poland is a party. Please see the International Legal Research Guide for more detailed information on how to conduct international legal research, including how to find other sources of international law. 

Treaties and International Agreements

Treaty research requires finding a full-text copy of a treaty or international agreement, then checking the status to see if it has entered into force, whether a party has ratified it, or if there have been any amendments.  

Copies of treaties and status information can generally be found on the depositary's website. A depositary is a government or organization to which the treaty is entrusted. Responsibilities include accepting all notifications and documents relating to the treaty, examining whether formal requirements are met, and notifying the parties of relevant acts. 

The example above indicates that Poland is a party to this convention via accession. Note that this page provides access to the full-text treaty (both the certified true copy as well as the version as published in the United Nations Treaty Series). 

For assistance with understanding treaty terminology (e.g., signatory, reservation, accession) when looking at status information, please see the UN Treaty Glossary
