Europe's highest court looks set to decide whether Google should remove links to articles in newspapers, including El Pas, from its online search engine following a Spanish demand about invasion of privacy. Google was ordered to remove almost 100 online articles from its search results by Spain's data protection authority earlier this year. The articles, some of which appeared in official gazettes, were subject to privacy complaints by their subjects. The US technology giant vowed to fight Spain's demand in a Madrid court, warning that it would have a "profound chilling effect" on freedom of expression. The case will now be referred to the European court of justice (ECJ), which will offer guidance on whether Spain's demands comply with European law potentially setting a controversial precedent for internet publishing in the country. Peter Barron, Google's head of European external relations, welcomed the development. "We're pleased that the court is considering asking guidance from Europe's top court on whether Spain's DPA has overridden European law," he said.
