Secondary school teacher Enoch Burke has told the High Court he intends to contest the application by his employer to have him held in contempt of court for breaching an injunction.
The Mayo native was arrested this morning at Wilson's Hospital School in Multyfarnham in Co Westmeath following an order by the court last Friday.
The school had been granted an injunction preventing him from attending or teaching at the school but Mr Burke had continued to turn up for his timetabled hours.
RTE is reporting that Lawyers for the school told the court he was "sitting in an empty classroom".
Mr Burke had been put on paid administrative leave by the school following a public confrontation with the principal over a pupil who wanted to transition.
Mr Burke told Judge Michael Quinn he would welcome the opportunity to briefly answer to the charge and opposes the application to hold him in contempt.
The case has been adjourned until the judge is finished hearing other unrelated matters.
