Governor-General to abolish a superannuation scheme established by the New Zealand Superannuation Act 1974, without new legislation. Muldoon felt that the dissolution would be immediate and he would later introduce a bill in parliament to retroactively make the abolition legal. This claim was challenged in court and the Chief Justice declared that Muldoon's actions were illegal as they had violated Article 1 of the Bill of Rights, which provides "that the pretended power of dispensing with laws or the execution of laws by regal authority ... is illegal." United Kingdom The Bill of Rights applies in England and Wales; it was enacted in the Kingdom of England which at the time included Wales. Scotland has its own legislation, the Claim of Right Act 1689, passed before the Act of Union between England and Scotland. There are doubts as to whether, or to what extent, the Bill of Rights applies in Northern Ireland, reflecting earlier doubts as regards Ireland. The requirement that jurors be freeholders in cases of high treason was abolished in England and Wales by the Juries Act 1825, and in Northern Ireland (to the extent it applied) by the Statute Law Revision Act 1950. Natural justice, the right to a fair trial, is in constitutional law held to temper unfair exploitation of parliamentary privilege. On 21 July 1995 a libel case, Neil Hamilton, MP v The Guardian, collapsed as the High Court ruled that the Bill of Rights' total bar on bringing into question anything said or done in the House, prevented The Guardian from obtaining a fair hearing. Hamilton could otherwise have carte blanche to allege any background or meaning to his words, and no contradicting direct evidence, inference, extra submission or cross-examination of his words could take place due to the tight strictures of the Bill of Rights. Equally the highest court decided that absent a 1996 statutory provision, the Bill of Rights's entrenched Parliamentary Privilege would have prevented a fair trial but to Hamilton in the 2001 defamation action of Hamilton v Al-Fayed which went through the two tiers of appeal to like effect. Section 13 of the Defamation Act 1996 was then enacted and permits MPs to waive their parliamentary privilege and thus cite and have examined their own speeches if relevant to litigation. Following the United Kingdom European Union membership referendum in 2016, the Bill of Rights was cited by the Supreme Court
