reached Novi Pazar while the northern border between the Dioceses of Mostar-Duvno and Trebinje-Mrkan remained unclear. Provicar of Trebinje-Mrkan Lazar Lazarević wrote to the Propaganda in Rome on 11 June 1887, again requesting the appointment of a new bishop and protection of Catholics from the new authorities. In mid-1887, Lazarević also wrote to the Austrian-Hungarian government in Sarajevo about Buconjić's encroachment in Trebinje-Mrkan but his petition drew no positive response. Lazarević also warned Vodopić about his duties as Apostolic Administrator but Vodopić showed little interest. Head of the Propaganda Cardinal Giovanni Simeoni asked the State Secretary Cardinal Mariano Rampolla to help with the improvement of the condition of Catholics in Trebinje-Mrkan. Rampolla informed the pope about the situation; the pope requested new negotiations with the Austrian-Hungarian government. Cardinal Luigi Galimberti, the new Nuncio in Vienna, started negotiations with Foreign Minister Count Gustav Kálnoky and showed him Rampolla's letter. Kálnoky informed the Minister of Finances Béni Kállay about the situation and in June 1888, Kállay ordered an investigation into the Buconjić's pretensions to Trebinje-Mrkan. Buconjić's predecessor Apostolic Vicar Barišić also requested subordination of Trebinje-Mrkan to him in 1846. On 5 September 1888, the clergy of Trebinje-Mrkan again asked Nuncio Galimberti for the new bishop and for Buconjić to respects the boundaries of Trebinje-Mrkan as established in the 1881 bull Ex hac augusta. On 17 June 1889, the Austrian-Hungarian government in Sarajevo and the Joint Ministry of Finance presented their proposal to Galimberti, in which they suggested the Bishop of Mostar-Duvno should administer Trebinje-Mrkan. The main motive for the proposal was not to dissatisfy the Eastern Orthodox population. The Austrian-Hungarian government also requested the Bishop of Mostar-Duvno, even though just an apostolic administrator, should have a regular jurisdiction in Trebinje-Mrkan and that he could appoint Franciscans to priestly duties. Cardinals Simeoni and Rampolla agreed with the first proposal but rejected the others. The Austrian-Hungarian government was informed about their decision on 23 September 1889. On 16 June 1890, the Propaganda decreed the bishop of Mostar-Duvno would administer Trebinje-Mrkan and the pope confirmed this decision on 8 July the same year. With the new decree, Buconjić's jurisdiction was extended to the whole of Herzegovina. In 1885, Buconjić proposed a change in the borders of the Bosnian-Herzegovinian dioceses to the Holy See. Buconjić and other two Bosnian-Herzegovinian bishops, Stadler and the apostolic administrator of Banja Luka Marijan Marković proposed the changes to the Holy
