Romanis Pontificibus is a papal decree, issued on 6 June 1975 by Pope Paul VI, that concerns the Herzegovina Affair: the Franciscan friars of Herzegovina took control of the local parishes and refused to hand them over to the local bishops and priests, despite the Franciscan vow of obedience. The decree specified the relative jurisdictions of the friars and the diocesan clergy. Historical precedent In July 1881 Pope Leo XIII, by the apostolic constitution Ex hac augusta, established the ecclesiastical province of Vrhbosna, which also contained Herzegovina, and appointed a residential bishop for the diocese of Mostar, to which he joined the ancient title of Duvno. Paul VI references Leo's Romanos Pontifices, an apostolic constitution of May 1881 which defined the relationship between bishops and members of religious institutes.

It is the responsibility of the local Ordinary to provide for the governance of parishes, while moderators of religious institutes are encouraged to offer their assistance to bishops, even by taking up, for a time, the care of parishes. Terms After consultation with Sacred Congregation for the Evangelization of Peoples or Propagation of Faith, the Pope decreed that "in consideration of the merits which the Friars Minor of the Province of Herzegovina have secured for themselves, the Holy See accepts that it be taken as a general rule that half of the faithful of the diocese of Mostar-Duvno remain entrusted to the pastoral care of the same religious, while the other half entrusted to diocesan clergy." Pastoral care of the parishes in Izbično, Klobuk, and Kongora was entrusted to the Friars Minor of the Province of Herzegovina, but they were required to turn over to the diocesan clergy the parishes of Blagaj, Jablanica, Ploče, and Nevesinje. Additional arrangements were made regarding other parishes.
