17 These proceedings have been on foot for 14 years. The evidence establishes that the Smiths have been aware of the substance of the matters which they now wish to assert against Mr McCusker QC for the entirety of that period, and indeed, for more than 20 years now. The Smiths sought, unsuccessfully, to raise these matters as part of these proceedings in 1997. They have recently renewed that attempt without proffering any explanation for the delay in bringing this application to amend their pleading. It might perhaps be inferred from the terms of the pleading that the Smiths justify their delay by reference to the matters which are said to have been discovered during 2008. However, as I have observed, those matters go only to the detail of the relationship between the Town and Country Permanent Building Society and the Bank, and do not affect the fundamental character of the issues asserted by the proposed amendments. Unexplained delay of this magnitude is, of itself, a powerful reason for disallowing the amendments proposed, especially when a trial is imminent.
