In Europe, the copyright infringement case Public Relations Consultants Association Ltd v Newspaper Licensing Agency Ltd had two prongs; one concerned whether a news aggregator service infringed the copyright of the news generators; the other concerned whether the temporary web cache created by the web browser of a consumer of the aggregator's service, also infringed the copyright of the news generators. The first prong was decided in favor of the news generators; in June 2014 the second prong was decided by the Court of Justice of the European Union (CJEU), which ruled that the temporary web cache of consumers of the aggregator did not infringe the copyright of the news generators.
