As a lawyer and an interested party here, I'd say this decision by Lewisham Council is highly susceptible to judicial review (i.e., being overturned by the High Court). By openly advertising that there would be a bulge class at the time we all made our six selections, influencing the way many of us made our choices, the Council created a legitimate expectation that a particular process would be followed. This is a breach of natural justice. If anyone might be interested in exploring the ground for a group challenge to this, PM me. http://en.wikipedia.org/wiki/Judicial_review_in_English_law
