Antoinette Sandbach, Member of Parliament for Eddisbury, says on her website
Although the Secretary of State has refused to formally extend the consultation closure date into the New Year, he has agreed to ensure that any further responses that I receive before 8 January 2019 will be considered by HS2.
Therefore if, after submitting your initial response, you have further comments to make, please send or e-mail these to my office by Monday, 7 January 2019 at the latest and I will ensure that they are forwarded to the Secretary of State for HS2’s consideration.
It was always a cynical decision on the Department for Transport’s part to finish the consultation on the last working day before Christmas Eve. It seemed highly unlikely that anyone from HS2 Ltd would be assessing the responses until the New Year, but it meant that individuals affected by HS2 couldn’t look at the consultation during their Christmas break. Just what we’ve come to expect with HS2 though!
