Teacher Enoch Burke has been arrested and brought to the High Court for allegedly breaching an injunction.
On Friday the court issued a warrant directing that he should be brought before it to answer claims that he had breached the order by attending Wilson's Hospital School in Co Westmeath.
The High Court has granted a permanent injunction directing him to stay away from the school.
However Mr Burke began attending at the school again after it reopened following the summer holidays.
The court was told last week Mr Burke’s continued presence at the school was stressful and disruptive for staff and students.
It was also told that the presence of unknown third parties outside the school and on the school grounds in support of Mr Burke posed health and safety issues for staff and students.
Mr Burke was sacked by the school in January last year but is appealing that dismissal. The appeal has not yet been heard.
He has spent more than 400 days in prison since September 2022 in two stints for breaching the High Court’s orders. He was released again in late June.
The situation has been described as being "without precedent" and being in "infinite deadlock".
The High Court had previously imposed a fine of €700 a day on Mr Burke for each day that he refused to comply with the injunction.
Previous hearings of the court have heard that the fine has not been paid and no measures have been taken against Mr Burke to force him to pay.
The court has also previously heard that Mr Burke continues to be paid his full salary pending the outcome of his appeal against his dismissal.
