In the 2013 landmark case between Google Spain v Marcio C. Gonzalez, in an instant Google – the world’s largest and most advanced search engine – had to comply with a European Union (EU) court outcome to erase personal information as requested by an individual.
The Spanish Data Protection Authority based its decision on EU Directive 1995/46EU. This would apply to any search engine data processor that is a processor of personal data. The court also determined that Google Spain is a Google affiliated company and thus Google Inc. Is subject to the EU Directive. So, in the end search engines that process an EU citizens information are subject to this directive.
