SUPREME COURT OF JUDICATURE, ENGLAND;PROCEDURE
These Rules make provision with regard to the use of decimal currency in proceedings in the Supreme Court, Pleadings filed on or after 1st October 1970 will be required to state the decimal equivalent of sums claimed other than those in whole £s (Rule 4), and to avoid the use of fractions of a new penny, conversions will have to be effected in accordance with the “whole penny” table in Schedule 1 to the Decimal Currency Act 1969 (Rule 2). All judgments given and enforcement process issued on or after 15th February 1971 (the date on which decimal currency will be introduced) will have to be expressed in the new currency (Rules 5 and 6). Decimal equivalents for the sums specified in Parts I to IX of the Scale of Costs which forms Appendix 2 to Order 62 of the Rules of the Supreme Court, are prescribed and the opportunity has been taken to abandon the use of folios as a means of calculating the costs allowed in respect of documents, and to sanction expressly the use of paper sizes in the International Standards Organization range (Rules 7, 8 and 9). Section 4(1) of the Administration of Justice Act 1969 made the costs sanctions against bringing in the High Court proceedings which could have been commenced in the county court applicable to actions brought to recover possession of goods, and the writ commencing such an action will have to state the value of the goods (Rule 3).
