The Court of Appeal granted security for costs of £70,000, rejecting the respondent’s application for £225,000 as disproportionate. The court held that where respondents would not have been entitled to security for costs at first instance, those costs should be excluded from security on appeal, including costs of defending a respondent’s notice.
