It is out of date, by four three (April to July). You linked to Porche's legal position prior to the court hearing, I linked to the position after the court hearing. Let me post the opening sentence from the latter: As I understand it the legal issue is Ken consulted the public with a set of data, and then some of the data was re-interpreted so the original consultation was underminded. Yet he continued with a policy based on the original data. If you're disputing the current authenticity of the Kings College data - which says pollution will rise as a result of the CC changes Ken proposed - I'd be very happy to see them as I'd like Ken to have been right?
