Claimant personal injury solicitors have hailed a Court of Appeal judgment dismissing an attempt to strike out an argument that periodical payments for future loss of earnings and future care costs should be indexed by reference to the average earnings index rather than the retail prices index. An Association of Personal Injury Lawyers spokeswoman said of the ruling in Singh Flora vWakom (Heathrow) Ltd: 'We hope the courts will now be encouraged to look at using different indices for different heads of damage.' Defendant lawyers said they were disappointed. Andrew Parker, head of strategic litigation at national firm Beachcroft, said: 'We are actively seeking permission to appeal. It is important to remember that all the court was considering was whether the claimant's case was even arguable, not whether it was right.'
