@RolloTreadway@ChrisMayLA6 With you Rollo, up to your concluding sentence, to which i might venture to add that the Courts also take into account principles of justice, fairness (equity) equality before the law, international norms & decisions of other Common Law jurisdictions, and the admissible scope of ministerial & administrative powers under, in particular, secondary legislation. Throw in a few 2000 year old precepts from Roman jurisprudence, too. So may it continue.
