A judge assessing quantum of security for costs is not acting as a costs assessor and may be guided by competing expert reports, adopting a figure between them. The process of estimation embodies necessary reliance on the judge's 'feel' of the case. An appellate court will apply a cautious approach to detecting error in such assessments, particularly where the judge's impressions of case complexity were instrumental. A judge is not required to state a specific percentage discount for prospects of early resolution; it is sufficient to balance the prospect of early resolution against the risk of the case going longer. Security by way of registered mortgage over unidentified land is not a sound exercise of discretion.
