The justices of the peace were one of the forms of participation of the society in the jurisdiction in the Second Polish Republic. This institution was inherited from the former partitioning states and did not exist throughout the country. Justices of the peace were provided for by the provisions of the Act amending the Law on the System of Ordinary Courts, but its provisions have never been implemented. Justices of the peace ended their activity in 1929, but their formal liquidation took place only in 1938. In the interwar period, courts of the peace were closer to professional courts, where judges were given significantly lower selection criteria than the actual form of social participation in the judiciary. Contrary to the provisions of the Constitution of 1921, justices of the peace were not elected by popular vote. The article deals with the issue of the justice of the peace in the Sejm of the Second Republic of Poland, especially in its first period (1919-1928), when it was a problem of great interest to parliamentarians. This is evidenced by numerous interpellations and parliamentary bills submitted by them, which the author analyses and quotes. On this basis, he draws the conclusion that the institution of justice of the peace was not supported by deputies, especially the agrarian and socialist parties. Often, justices of the peace were (in interpellations) blamed for corruption, nepotism, and incompetence The solution to this problem was seen in more fully admission of society to participate in the judiciary.
