due to intrigues, it was revealed that his father ivan kőszegi was married, when he was born. consequently, kőszegi requested pope john xxii to exempt him from this requirement in the first half of 1325. the pope granted this exemption on 30 july. in the next year, there were reports of looting and seizures of his diocese's certain lands and estates, as well as the neighboring diocese of passau. upon kőszegi's request, pope john placed the diocese of győr under the protection of the holy see in january 1327. the pope also appointed henry, bishop of veszprém as kőszegi's defender (""conservator"") in june in order to restore benefice of the diocese. according to ádám vajk, nicholas' stepbrother john the wolf was behind the attacks against the diocese of győr. accordingly, he transuded private information to the holy see about the bishop's parentage, in order to turn him out of office, and occupied szombathely and other bishopric estates in vas county. plausibly, he turned against nicholas in connection with another open rebellion of the kőszegis in 1327, to which the bishop refused to join.
