Before his resignation and conversion Haugwitz appointed Johannes Leisentritt as diocesan administrator, seated in Bautzen, competent for the Lusatian areas of the diocese outside of Saxony. Leisentritt failed to win the pope for establishing a new diocese comprising only the Lusatian areas of Meißen bishopric. However, in 1567 the Holy See separated the Lusatian areas from the Saxon parts of the diocese and established there the "Apostolic Prefecture of Meißen", seated at St. Peter's in Bautzen, with Leisentritt as its first prefect. In canon law an apostolic prefecture is a diocese on approval.
