In ‘the common judicial enterprise’, the frontiers of international and national realms are becoming blurry in recent decades, as more often than before international and domestic tribunals need to apply international law in exercising their judicial functions.

Echoing his findings, Mr Adrian Lai focused on the Hong Kong context in citing several well selected cases and depicting a balanced picture of the courts’ general stance towards international jurisprudence.
