Dispute Resolution analysis: Christopher Snell, barrister at No5 Chambers (London), considers the case of Manorshow Ltd v Boots Opticians Professional Services Ltd. An application to substitute Boots as defendant was allowed in circumstances where all parties agreed that Boots was not the correct defendant, but a related party, European Vision Limited (EVL), was the correct party. Further, Boots had been joined as defendant as a result of its own conduct. That weighed heavily in favour of the CPR 19 discretion being exercised in Manorshow’s favour. Boots, having necessitated the substitution application by reason of its own conduct, would bear the costs of the substitution application.
