Dated 14th April 1978
Parts II and III of these Rules make amendments to the Rules of the Supreme Court to take into account the provisions of the Torts (Interference with Goods) Act 1977 and the Patents Act 1977. Part IV enables appeals to the High Court under the Matrimonial Proceedings (Magistrates' Courts) Act 1960 to be heard and determined by a single Judge instead of a Divisional Court where only the amount of any weekly payment is in issue. It also brings up to date a reference in Order 91, rule 4, to Order 91, rule 1.
The relevant amending instruments are S.I. 1968/1244, 1971/1955, 1972/813, 1975/911, 1976/337, 1196, 1977/532.
