My Lords, I am extremely grateful to the noble Lords, Lord Bradshaw and Lord Berkeley, and indeed the noble Lord, Lord Grocott, for their very positive contributions to this important debate. I am sure the House will agree with the point made by the noble Lord, Lord Berkeley, that we are grateful to the noble and learned Lord, Lord Walker, and to members of the committee who have taken on this task. As the noble Lord, Lord Grocott, said, it is an important task and I think that we handle this matter in a very open and positive way in this country. I am sure that the committee that has taken on this task is mindful of the need to get on with it. I am full of admiration for members’ willingness to devote so much time to this process in order that it can be done in a timely manner.
The amendment in the name of the noble Lord, Lord Bradshaw, is about a technical expert adviser. The hybrid Bill procedure means that the committee operates in a quasi-judicial manner and hears the evidence presented to it by the parties transparently and in public. Advice from a specialist adviser would not be public, and that could undermine that commitment to transparency. However, we intend to look again at the hybrid Bill procedure, with a view to seeing whether there are practices which could be improved. In that exercise, we will consider further the point made by the noble Lord with a view to the procedure used for future hybrid Bills. It would not be appropriate, however, to institute changes before that process has taken place.
The second amendment, in the name of the noble Lord, Lord Berkeley, proposes taking away the standard power given to committees to publish evidence,
“if the Committee so wishes”.
It is usual for committees to publish evidence and, as I am sure is known to many noble Lords, the convention is that all evidence is published shortly after receipt unless there are extenuating circumstances. The power to publish evidence is routinely given to Select Committees in these terms as it allows them to publish evidence, including transcripts of oral evidence sessions, during the course of their inquiry rather than only when they report.
On the instruction to the committee proposed by the noble Lord, Lord Bradshaw,
“to focus on petitions where substantial costs savings could be achieved”,
I anticipate that the committee will consider all the petitions equally and fairly. It would not be appropriate to instruct the committee to focus on particular petitions at the expense of others. As important as costs are, they are but one factor among many. The relative merit to be attributed to petitions is in my judgment a matter rightly to be left to the committee to manage.
Finally, in relation to the second instruction, it is for the committee to decide on its own days and hours of sittings. As I have indicated, its members have set aside such time to this project that we should be grateful to them. I know that noble Lords are aware of the significant time commitment but also of the committee’s willingness to do this in timely manner.
I hope that it will not be necessary for this House to give an instruction. On that basis, I hope that the noble Lord will withdraw the amendment and that neither he nor the noble Lord, Lord Berkeley, will consider that the remaining amendments and instructions should be moved.
I do not want to prolong this, but I underline the point that what the noble Lord has said makes it very difficult for the huge economies that can be made in this scheme to be bought out. The petitioners cannot afford to present their technical evidence because it costs a lot of money, but if the committee were to take the initiative at least to take the advice of somebody, I am sure that we would come to quite different conclusions. HS2 has had a monopoly on the input; it is time that was tested.
Surely it is within the remit of the committee, if it wants to hear expert evidence, to call an expert in front of it to give it. As I understood it, if the committee wants guidance, it can call evidence, the evidence is heard and cross-examined and it becomes part of the evidence of the committee.
