As a castellany, Biecz was not only entrusted with defensive responsibilities, but also served as judicial, administrative, and economic center for southern part of Kraków Voivodeship. After a lull in economic and population growth in the latter half of the 14th century, the judiciary and administration of the region were reorganized. The region of Kraków, or Kraków Voivodeship was established, and was further split into six powiats (districts), one of which was the large district of Biecz. Biecz was then designated a judicial center, and was home to two different court systems. Kraków, Nowy Sącz, and Biecz were the locations of the high courts that dealt with the enforcement of the Magdeburg laws as established in 1374 by the Privilege of Košice.
