Chalfont St Peter Parish Council has been granted permission to appeal a judicial review.
Persimmon Homes was given permission to build 198 homes and a 75-bedroom care home at the former Holy Cross School site site on appeal to the planning inspectorate. That decision was confirmed in the high court after the parish council challenged the planning permission.
Chalfont St Peter CoE Academy wants to relocate to the Holy Cross site to give the children more space and facilities.
Parish councillor Richard Allen told the Bucks Free Press that in the high court hearing: “The key questions we raised in court at the very beginning were never addressed”.
