When the See of Freising in Bavaria fell vacant in August 1443, there were two candidates for the succession: Heinrich Schlick, brother of the imperial chancellor, the powerful Kaspar Schlick, and Johann Grünwalder, the illegitimate son of a Bavarian duke, and one of the cardinals of antipope Felix V. The matter was examined at a hearing before Emperor Friedrich III in Wiener Neustadt on 4 April 1444. Johann Grünwalder spoke for himself, and the chancellor for his brother. The chancellor’s speech was largely written by his protégé, Enea Silvio Piccolomini of the Imperial Chancery. In his speech, Schlick put forward a number of political and legal reasons for appointing his brother. He also made a spirited defence of papal supremacy against the Council of Basel, and argued in favour of ending German neutrality between pope and council and of full German recognition of Pope Eugenius.
