The board voted last year to close Reverend H.J. MacDonald School in Heatherton and the West Richmond Education Centre in Evanston.
However, parents and residents from both communities filed for a judicial review of the decision.
The case was heard in a Port Hawkesbury courtroom in August.

He says his clients have yet to decide whether to appeal the decision.
