From the Consultation documents:
The questions on which the Government is seeking views are set out below. In each case, the Government is interested in whether or not you agree with its proposals and why, as well as any additional evidence that you feel it should consider in reaching its final decisions.
v) This question is about the route for the line between London and the West Midlands (Chapter 5 and Annex B): Do you agree that the Government’s proposed route, including the approach proposed for mitigating its impacts, is the best option for a new high speed rail line between London and the West Midlands?
As the principles on which the route were based are invalid, this question is invalid.
For it to be valid, it would have to be shown that there was an economic case for building a high speed railway – currently the subject of a Transport Select Committee Inquiry – and that the design principles, such as speed, were appropriate. The Department for Transport have not demonstrated either of these.
Therefore the Stop HS2 answer is “no”.
