The High Court granted an order for costs in favour of the applicant after the applicant succeeded in quashing a decision of the planning authority, having been wholly successful in obtaining certiorari on one of several grounds raised in judicial review proceedings. The court found that the applicant was not penalised for raising multiple arguments where no ground was determined in favour of the planning authority and considered the approach appropriate given that the key ground could have been conceded at an earlier stage. The court rejected the respondent planning authority's submission to reduce costs due to the number of issues advanced and clarified that costs should follow the event unless specific factors justify a departure.
