Casimir's Code (Belarusian: Судзебнік Казіміра; Lithuanian: Kazimiero teisynas; Polish: Statut Kazimierza), also known as the Sudebnik of 1468,[1] was a legal code adopted by Grand Duke of Lithuania and King of Poland Casimir IV Jagiellon with the approval of the Lithuanian Council of Lords.

[2] The code prescribed punishment for property crimes and limited court procedures.

The historians conjured that the most probable date is February 1468 when the Seimas of the Grand Duchy of Lithuania met in Vilnius.

Judging from the content, the code was intended for the nobility and landowners, who received Casimir's privilege in 1447 to try veldamai, a class of dependent people that eventually became serfs.

[3] Written in the Ruthenian language,[4] the original document did not survive, but several copies are known from the end of 15th and beginning of the 16th centuries.

The code primarily dealt with common thieves, but also addressed crimes by the Lithuanian nobility (such as cutting forest trees without permission or luring away veldamai from another noble).
