Former Kensal Rise Library Planning Permission

The former Kensal Rise Library building is finally coming up for planning permission on Wednesday, having been deferred from a previous meeting.  The lawyers have come back essentially repeating their previous advice, which I find unsurprising.  However, I am surprised at one aspect, which is the reference to the Council being given "first refusal".  I thought that even if this condition is lawful in the first place, the building's status as an "asset of community value" means that it has to be made available to any group or groups that want to bid for it.  Thus, I would have thought the "first refusal" condition unlawful.
