How did the university voting system favour German masters before 1409?

Before 1409, the University of Prague utilized a voting system based on four "nations": Bohemian, Bavarian, Saxon, and Polish.12

Although the Polish nation was composed largely of Germans, it functioned as a distinct voting bloc alongside the Bavarian and Saxon nations. Because each of these four nations held one vote on matters of general policy, the three "foreign" nations—all dominated by German masters—collectively controlled three votes, while the Bohemian nation held only one. This structure consistently allowed the more numerous German masters to outvote the Czech members on important university decisions.132

This imbalance was eventually corrected in 1409 when King Wenceslas issued a decree at Kutná Hora that reversed the voting proportions, granting the Bohemian nation three votes and the three foreign nations a single combined vote.3
