The City Council's due to take the final decision on the planned expansion of Gilmour Infants and Junior Schools later this month.
It's already agreed once, but under the law the proposals then have to go through a process to see if there are any objections.
So in effect these decisions have to be taken twice.
A petition about one of the expansions has come in, so the Cabinet will take another decision at its meeting on 16 May.
The relevant paperwork for the 16th May meeting isn't available yet but the brief details are at this link.
