Dominus Stanisław Kostka (*1487 – †1555), as a leader of the so-called nobles' party active in Royal Prussia since 1536, Kostka stood in opposition to most of the members of the Council of Royal Prussia, who wanted to maintain the autonomy of the province and a "balance of power" in terms of governance. The tension between the Prussian Subtreasurer and the Council had been increasing since the Diet in Graudenz (Grudziądz) in 1533. Kostka, connected with the royal court since his youth, was sent to Graudenz as the King's deputy and, contrary to custom, decided to take part in the proceedings. In response to such a step, the Council members stopped the meeting. Kostka accused them of hostility towards the Poles and intervened on this matter at the court. In the absence of the then Bishop of Ermland (Mauritius Ferber) it was Dantiscus who chaired the Graudenz Diet. The incident badly harmed his future relationships with Kostka; 1531-1555 Treasurer of the Prussian lands and Treasurer of Marienburg (Malbork); 1544-1545 Castellan of Elbing (Elbląg), 1545-1546 Castellan of Kulm (Chełmno); 1546-1549 Vice-Voivode of Kulm; 1546-1551 Voivode of Pomerania; 1551-1555 Voivode of Kulm (PSB 14, p. 356; Urzędnicy 5/2, p. 216; MAŁŁEK 1976, p. 119-123)⌊Stanislaus CosthkaStanisław Kostka (*1487 – †1555), as a leader of the so-called nobles' party active in Royal Prussia since 1536, Kostka stood in opposition to most of the members of the Council of Royal Prussia, who wanted to maintain the autonomy of the province and a "balance of power" in terms of governance.

Certe mirati sumus et ferme obstupuimus litteras de hoc casu legentes, scientes ipsam semper fuisse bonum Polonum et nunc sese alium prae se ferre, si credendum est. Tametsi Prussia iura et consuetudines suas habeat, tamen pars Regni est et omnibus dominis conceditur honor consularis in consilio Regni, verendum itaque est, ne eiuscemodi separationibus invehatur suspicio ad odia promovenda.
