Wilson's Hospital School in Co Westmeath is bringing new proceedings to have teacher Enoch Burke arrested and jailed for breaching court orders by trespassing at the school.
Mr Burke was released from Mountjoy Prison yesterday afternoon.
He had been jailed in November for contempt of court. He has now spent more than 560 days in prison since September 2022.
Mr Justice Brian Cregan released Mr Burke to allow him to prepare for a legal challenge he is taking against a Disciplinary Appeals Panel hearing his appeal against his dismissal from the school.
Mr Burke said he did not need to be released to prepare for the case, and he said he planned to go straight back to the school, which he described as his workplace, this morning.
Barrister Rosemary Mallon told the court that less than 24 hours after being released from prison, Mr Burke had returned and trespassed on the school grounds.
She said Mr Burke had arrived at the gates at around 9.30am.
He had entered the school grounds and the principal had personally viewed him standing a number of feet past the gate.
There was also a photograph showing him inside the school grounds.
Ms Mallon said there were also a number of protesters with placards and two flags gathered at the gates.
Some of them, she said, had also passed through the gates.
She said the school was concerned at the health and safety risk posed by these protesters.
Ms Mallon said the school found itself in a "really invidious position".
She said the court had made it clear to Mr Burke that he was being released to allow him to prepare for litigation and that he was not to trespass.
Mr Justice Cregan said he had made it "crystal clear" and Mr Burke was fully aware of this.
However, Ms Mallon said Mr Burke had decided this morning to "once again ignore the rule of law".
She said school teachers found it difficult to access the school because of the protesters.
While people had a right to protest outside the gates, she said it was highly doubtful whether there would be protesting to such a degree without Mr Burke's presence.
Mr Justice Cregan gave the school permission to serve notice of the attachment and committal proceedings on Mr Burke by email.
He said he expected to see Ms Mallon and Mr Burke back in court at 2pm tomorrow.
