Campaigners opposed to a new grammar school in Kent say they've been unable to determine whether the plans are legal because of difficulty obtaining background information.
However the Comprehensive Future group has stopped short of calling for a judicial review into the plans.
The Government approved a proposal in October last year for the first new grammar school for 50 years to be built in Sevenoaks.
But to sidestep the rules on creating new grammars, the Government says it agreed not to a new school but an annex of the Weald of Kent School in Tonbridge.
The group says it intends to keep a close eye on the development of the school and in particular says it will be scrutinising details of the school’s plans when published in the funding agreement.
The school is due to open in September 2017 after a long campaign by parents who say there is a desperate need for more grammar places in West Kent.
