“The only constraints on the broad and far-reaching nature of the interpretative obligation are that: (a) the meaning should go with the grain of the legislation and be compatible with the underlying thrust of the legislation being construed: see per Lord Nicholls in Ghaidan v Godin-Mendoza[2004] 2 AC 557 , para 33; Dyson LJ in Revenue and Customs Comrs v EB Central ServicesLtd[2008] STC 2209 , para 81. An interpretation should not be adopted which is inconsistent with a fundamental or cardinal feature of the legislation since this would cross the boundary between interpretation and amendment (see per Lord Nicholls, at para 33, Lord Rodger, at paras 110—113 in Ghaidan’s case; per Arden LJ in R (IDT Card Services Ireland Ltd) v Customs and ExciseComrs[2006] STC 1252 , paras 82 and 113); and (b) the exercise of the interpretative obligation cannot require the courts to make decisions for which they are not equipped or give rise to important practical repercussions which the court is not equipped to evaluate: see the Ghaidan case, per Lord Nicholls, at para 33; per Lord Rodger, at para 115; per Arden LJ in the IDT CardServices case, at para 113.”
“I guess it depends if getting them started, albeit slightly incorrectly, is more important or if it’s more important that everything is right first time. If the later then the start dates would need to be1st Jan 2018 .”
