Mr Justice Auld, who heard the five day case ending on Monday, has reserved judgment, which means he could announce his decision at any time. Until then, Kingswood nursery in East Finchley must not close. The council had thought the hearing would last only two days and planned to close Kingswood last Friday, moving the 12 remaining children to other nurseries in the borough.
British Telecom, which had not been told of the injunction, disconnected the phones last Friday morning, leaving just a payphone for emergencies. The lines were reconnected later that morning after the judge was told of the blunder.
Six toddlers are bringing the action under the Children Act 1990. Their parents claim they were not properly consulted about the closure.
