PLANNING chiefs have failed to give enough time for protests to be made against a school expansion plan, say objectors.
One said notices advertising the plan were not on display for long enough at Nortonthorpe Hall School, Scissett.
It was also said that the signs were not in the right position and did not contain much detail.
The allegations have been made as councillors prepare to visit the site before making a decision on planning permission.
A single-storey detached dining and activity hall is proposed.
The Busker Lane school has 69 pupils, aged from seven to 16, who have behavioural difficulties.
Kirklees councillors will go to the site on Thursday before deciding immediately afterwards if the scheme can go ahead.
Planning officers are urging that the project is approved.
Their report said: "The development would normally be considered inappropriate in the Green Belt.
"But there are special circumstances, because it is needed for the operational requirements of the school and would not be detrimental to rural character."
The present hall will be demolished to make way for the new building, which is needed to cope with increased pupil numbers.
One objector said it would be too near a neighbouring house.
