According to the web portal Siol.net, Mramor and Tekavčič failed to refute the accusations of contentious paying out of bonuses during the investigation.
Along with deputy dean and former deputy dean of the faculty, Polona Domadenik and Mojca Indihar Štemberger, respectively, they are facing between three months and five years in prison.
During the investigation, it was determined that the suspects enabled specific employees of the faculty to receive stand-by bonuses contrary to the act on public servants and the public sector pay system act.
The faculty refused to comment on the case for the STA due to the on-going procedure. It said only that the faculty had stopped paying the contentious bonuses in January 2016 and had fully implemented an order of the public sector inspectorate on the returning of the contentious bonuses.
Mramor told the STA that the indictment was not final yet and that he planned to challenge it.
He claims that the bonuses had been paid out based on a "solid legal foundation" of the faculty, which the state prosecution now wrongly interprets.
He called the indictment "misleading" and "inaccurate", noting that it did not take into account a single testimony of over 70 witnesses who were heard during the investigation and who "clearly stated" that the stand-by was necessary for the staff to be able to conduct their work on time for the faculty to achieve its goal of being listed among the best faculties in the world.
The former minister also said that the Public Administration Ministry had launched the proceedings against the faculty through the public sector inspectorate although it was also paying out stand-by bonuses to its staff on the same legal foundation.
Tekavčič upheld Mramor's arguments, adding that the stand-by bonus had been introduced in 2008, five years before she took over. According to Radio Slovenia, she had appealed to the indictment before the court's summer recess.
The scandal over generous bonuses paid out to faculty members by eleven University of Ljubljana faculties erupted in late 2015. Almost EUR 781,000 in gross stand-by bonuses was reportedly paid out between 2012 and 2014.
Subsequently, Mramor resigned as finance minister on 13 July 2016, while incumbent Education Minister Maja Makovec Brenčič was also among those implicated.
The treasury has since recovered the majority of the unlawful payments, with Mramor, Tekavčič and Makovec Brenčič returning their bonuses.
