ENThe paper deals with the question of authenticity of the judicial charter that was allegedly issued by Vytautas, the Grand Duke of Lithuania, on the legal case between Švitrigaila and Andrey Vasilo, at the end of the 14th century. Analysis of the pseudo-original found in the Department of Written Sources of the State Historical Museum in Moscow allows to draw the conclusion that it is, indeed, a forgery, copied from a reproduction of an original Vytautas' charter published in the 1820s. The same is true of another recently published Vytautas' charter known from a 19th-century copy. [From the publication]
