An excerpt from a speech made on 3 March 2016 at the Justice Innovation Programme Lecture for the Northern Ireland.
6. Traditionally, our essential historic function has been
(i) to clarify the law when it may have become unclear,
(ii) to correct the law when it appears to have gone wrong,
(iii) to modernise and develop the law when it has become out-dated or out of touch, and
(iv) to reconcile and resolve inconsistent decisions of different courts.
