The High Court has ordered that teacher Enoch Burke should be arrested again and brought before the court for breaching an injunction directing him not to trespass at Wilson's Hospital School.
The court was told his actions were having an unprecedented and significant impact on the Co Westmeath school.
Mr Burke was released from prison two days ago having spent Christmas in jail for previously breaching the court order.
However, the school’s lawyers told the court that he turned up at the school again less than 24 hours after being released and attended at the school again today.
Mr Burke was not in court when the case was called although members of his family were seen in the environs of the building earlier.
Barrister Rosemary Mallon said she had been informed shortly before the case started that Mr Burke was at the school.
She said he had gone beyond the boundary walls of the grounds again today. And she told the court his actions were having an unprecedented and significant impact on the day to day work of the school.
Ms Mallon said Mr Burke was a member of a regulated profession with a code of conduct, but he had continued, no matter what was said to him by any judge, to turn his back on the requirement to obey the rule of law.
She outlined what the school’s principal had to do over the last two days as a result of Mr Burke.
She said he had to rearrange security at the school, liaise with the company and the security guard, address issues with students, teachers and parents trying to get past protesters and provide instructions to lawyers.
None of that, she said, was what a principal should be doing.
She said "with great regret" she was asking that Mr Burke be committed again to Mountjoy Prison.
Enoch Burke criticised Judge Brian Cregan, who delivered today's High Court order for the teacher to be arrested again.
Speaking after breaching an order to stay away from Wilson’s Hospital School for a second day running, he insisted he was not trespassing at the school.
