Megarry was appointed as a
High Court judge in 1967, assigned to the
Chancery Division, and received the customary
knighthood. He became Vice-Chancellor of that Division in 1976, effectively its head, as the deputy of the absent
Lord Chancellor. He was sworn of the
Privy Council in 1978, and held the new post of Vice-Chancellor of the Supreme Court from 1982 to 1985. He had a traditional view of the law, and was unwilling to set new
legal precedent. In
Gaiman v National Association for Mental Health, he ruled that the
National Association for Mental Health was able to expel 302 suspect members, to prevent a suspected take-over by the
Church of Scientology. In
Midland Cold Storage v Steer he denounced picketing by dock workers as "the law of the jungle", but held that he had no jurisdiction to ban it, deferring to the
National Industrial Relations Court. He was the first Chancery judge to sit outside London, when he attended a mock funeral in
Iken in Suffolk to test how easy it would be to carry a
coffin along an alleged
right of way in
St Edmundsbury and Ipswich Diocesan Board of Finance v Clark. Megarry sat in the case of
Tito v Waddell (No 2), brought by the former residents of
Banaba Island,
Gilbert and Ellice Islands, whose island was all but destroyed by
phosphate mining. Sympathetic to the grievances of the Banaban people, he described the 1947 transaction between the Banabans and the
British Phosphate Commission as a "major disaster" for the Banabans. He took the court on a 3-week trip to the south Pacific, to visit the island. After sitting for 206 days, he delivered a judgment containing 100,000 words. He asked
the Crown to do its duty to the islanders, but found that he was unable to require it to do anything. He was appointed as vice-chancellor in 1976. In 1977, he declined to grant
The Beatles an injunction to prohibit the sale of an unauthorised record based on informal and unrehearsed tapes. In 1979, he upheld a worldwide playing ban imposed on
George Best by
FIFA arising from a complaint by Best's former employer,
Fulham Football Club. Also in 1979, he was unable to uphold a complaint in
Malone v Metropolitan Police Commissioner, regarding
phone tapping during a police investigation. However, in 1984 the
European Court of Human Rights decided that it was a contravention of the
European Convention on Human Rights. Megarry ordered
Granada Television to disclose the name of a confidential source in 1980, following leaks of information from
British Steel Corporation. He ruled in two cases involving the
National Union of Mineworkers in 1984. In the first case,
Cowan v Scargill he declined a request from the
National Coal Board for a mandatory order to direct union representative how to act as trustees of a pension fund, but gave directions on the representatives'
fiduciary duties instead, saying that in his opinion the trustees were obliged to consider investment outside the UK and in industries that compete with coal. He would have said breach of the former would have risked the miners leaders being in
contempt of court; breach of the latter would simply enable them to be removed as trustees. In the second case, a month later, he prohibited the NUM from calling a strike in Nottinghamshire, because a ballot had not been held, and then declared that an NUM plan to discipline non-striking miners was illegal. He was chairman of the
Incorporated Council of Law Reporting for 15 years, from 1972 to 1987. == Legal writings ==
