“…the court now has a very salutary power, both to be exercised in a claimant's favour or, where appropriate, in a defendant's favour. It enables the court to dispose summarily of both claims or defences which have no real prospect of being successful. The words "no real prospect of being successful or succeeding" do not need any amplification, they speak for themselves. The word "real" distinguishes fanciful prospects of success or, as Mr Bidder submits, they direct the court to the need to see whether there is a "realistic" as opposed to a "fanciful" prospect of success.”
