[3] Three years later, he was appointed Voivode of Transylvania and ispán of Szolnok County,[4] when a series of royal concessions to the aristocracy forced Roland Borsa to resign his voivodeship in favour of Apor Péc, even though his estates laid mainly in Transdanubia.
According to Romanian historian Tudor Sălăgean, Apor exerted his office from outside the province and "merely instituted an exploitation regime to the benefit of the Hungarian aristocracy".
Following the death of Matthew II and Peter I Csák by 1284, their baronial group which imposed Apor as voivode broke apart, thus he lost his dignity soon.
[8] In this capacity, he and one of his brothers, Lucas conquered by force the Tátika Castle which owned by the Diocese of Veszprém and built by Zlaudus Ják decades earlier.
In parallel with this, his deputy, vice-judge royal Martin Devecseri was considered the monarch's personally appointed confidential expert, and himself took an effective judicial role.
For instance, Apor Péc nominated a notary to the judicial court, which resided in Buda, to represent his interests, which reflected Devecseri's institutional independence from him.
[11] Maintaining the short-lived dual system in the dignity in order to avoid power struggle, which characterized the late reign of Andrew III, Apor Péc became Palatine of Hungary for the Cisdanubian region (Latin: palatinus citradanubialis) – simultaneously Roland Rátót was responsible for Transdanubia – in 1298 and held that office until the next year.
[13] Andrew's death and the extinction of the Árpád dynasty marked the era of the Interregnum (1301–1310), when civil war between various claimants to the throne —Charles of Anjou, Wenceslaus of Bohemia, and Otto of Bavaria — broke out and lasted for seven years.
Majority of the historians, including Gyula Kristó and Jenő Szűcs, considered, these barons, Matthew III Csák, Amadeus Aba, Ivan Kőszegi, Stephen Ákos, James Borsa, Roland Rátót and Apor himself were arbitrarily took and used the title, which marked its devaluation.
In addition to them, two co-palatines of the previous year, Roland Rátót and Apor Péc also received the title as a counterweight, according to Zsoldos' theory.
One of the basis of Zsoldos' theory is the fact that Roland Rátót and – even more – Apor Péc were considered as much less important persons than, for instance Matthew Csák or Amadeus Aba.
