An amendment will be refused if it has no real prospect of success. The test is the same as for summary judgment.
Quah Su-Ling v Goldman Sachs International [2015] EWHC 759 (Comm)
Very late applications to amend require the applicant to demonstrate the strength of the new case and why justice requires its pursuit. Lateness is a significant factor.
Quah Su-Ling v Goldman Sachs International [2015] EWHC 759 (Comm)
In 'best judgment' assessments, the tribunal's jurisdiction is initially supervisory (judicial review-like), then fully appellate regarding the assessment amount.
Rahman (trading as Khayam Restaurant) v Customs and Excise Commissioners [2002] EWCA Civ 1881, Mithras (Wine Bars) Limited v C&E Comrs [2010] UKUT 115 (TCC)
A successful 'best judgment' challenge of a judicial review type is extremely rare; there's a presumption that the Commissioners made an honest attempt at a fair assessment.
Mithras (Wine Bars) Limited v C&E Comrs [2010] UKUT 115 (TCC)
The application to add the 'best judgment' ground was refused.
The new ground lacked merit, had no real prospect of success, and was brought after an inordinate and unexplained delay of seven years. The underlying issue was already decided in the dismissed judicial review claim.
