Teacher Enoch Burke has been dismissed from his position at Wilson's Hospital School in Co Westmeath.
A statement issued through one of his brothers said that Mr Burke had attended the school today and was informed at 3.30pm in the presence of the Chairperson of the Board of Management John Rogers, and Principal Frank Milling that he had been dismissed.
Mr Burke said the decision had been taken after what he described as the "purported" meeting of the Board of Management in Mullingar Park Hotel from which Mr Rogers was absent.
A disciplinary hearing involving Mr Burke took place yesterday, in relation to alleged gross misconduct at the school.
On Wednesday, the High Court had refused to grant Mr Burke an injunction to prevent the hearing.
Mr Justice Conor Dignam said the applicant's intention to continue to breach court orders against him, meant the balance of justice tipped against allowing the injunction.
Mr Burke was jailed in early September after breaching a High Court injunction directing him to stay away from the school.
He had been suspended on full pay by the school as part of a disciplinary process, following a row over a request from a student to be addressed by a new name and for "they/them" pronouns to be used.
He was released from Mountjoy Prison on 21 December, and has continued to attend at Wilson's Hospital school since it reopened after the Christmas holidays on 5 January.
According to a circular from the Department of Education, a teacher who has been notified that disciplinary action is to be taken against him or her has 10 school days to request a review of the proceedings by a disciplinary review panel.
A teacher may seek such a review on a number of grounds, including claims that the procedures were not adhered to, that all the relevant facts were not ascertained or considered or that the teacher concerned was not afforded a reasonable opportunity to answer the allegation.
