The Supreme Court has been asked to hear an appeal in the case of a baby who was taken into the care of the Health Service Executive when he was one day old.
The High Court ruled yesterday that the emergency care order, under which the baby was taken into care last Thursday, was valid and the baby was lawfully in the custody of the HSE.
Lawyers for the baby, suing through his mother, are appealing that decision.
The Supreme Court was told it was a matter of great urgency.
The emergency care order runs out on Thursday and it is expected the HSE will ask the district court for an interim care order.
The High Court was told the executive had concerns about the baby's safety because of the behaviour of his father.
The High Court heard that the mother did not have enough opportunity to prepare for the original district court hearing and that gardaí had surrounded the house while she was breast feeding her baby and prevented her from going to court.
Mr Justice Sean Ryan ruled the rights of the mother to fair procedures were outweighed by the State's duty to protect a helpless baby.
Mr Justice John Murray said the appeal was a serious and urgent matter.
It will be mentioned in the Supreme Court again on Friday morning with a view to getting the earliest possible hearing.
