Understanding this distinction is crucial because s 5(5) of the SCTA provides that, if a tribunal is of the opinion that a claim lodged is beyond its jurisdiction, it must discontinue the proceedings. This is non-optional. By contrast, limitation is a defence that must be specifically pleaded (s 4 of the LA). Accordingly, courts are not obliged to consider it if it has not been pleaded; and, as a corollary, where parties have a claim and counterclaim which they both know (or suspect) are time-barred, but they nonetheless want their dispute to be adjudicated, it is perfectly permissible for them to agree to drop their respective limitation defences in order to obtain a decision on the merits (see, eg, The Oxford Architects Partnership v The Cheltenham Ladies College [2006] EWHC 3156 (TCC) at [15] where Mr Justice Ramsey said: “A party is not obliged to rely on a statutory limitation defence but is generally entitled to do so. It is possible for a party to agree that it will not rely on a statutory limitation defence or for the parties to agree that a statutory limitation defence will apply from an agreed date, for instance in a standstill agreement”).
