The Commission of the European Communities has decided that Racal Decca Marine Navigation Ltd had infringed the competition rules of Articles 85 and 86 of the EEC Treaty. The Decision follows an investigation of a complaint made by Rauff & Sorensen A/S of Denmark. Racal Decca developed the Decca Navigator System (DNS) which operates worldwide, including in several EEC countries: Belgium, Denmark, France, Germany, the Netherlands and the United Kingdom. The system consists of radio signals transmitted by land-located stations and received by devices fitted into vessels. Until 1981 Racal Decca was the sole supplier of DNS signals and DNS receivers. Because of its high accuracy, coverage and range there are as yet no substitutes for DNS in the relevant EEC area. However, from 1981 onwards Racal Decca had to face competition from DNS- compatible receivers made by other manufacturers which entered the market in Denmark and the UK. Racal Decca protected its dominant position through market and customer allocation agreements which kept important competitors (AP-Philips and PE-Navstar) out of the market, and by exercising pressure on competitors unwilling to enter into agreements (Rauff & Sorensen), in particular by changing radio signals ("jamming") in order to cause competing receivers to malfunction. As a result of the Commission intervention, Racal Decca has now agreed to abandon all these practices which is the reason why no fine has been imposed. Nevertheless this behaviour of Racal Decca, although ended, was an infringement of Article 86 and the agreements they concludedwere an infringement of Article 85 of the EEC Treaty.
