It might be difficult to spell out in the Bill exactly what the court must do to calculate the revaluation. I will consider what the hon. Gentleman said, but it would be difficult to lay down a set of proceedings that the court must follow when calculating movements in the value of money. The court must try to be just when updating the decision, and subsection (11) provides for that. I will consider whether there is a way of spelling out the calculation that would not lead to injustices that no hon. Member wants.
