The European Court of Justice ruled that the individual could demand that “irrelevant or outdated” information be deleted from results.
Mr Wales, founder of Wikipedia said it was “one of the most wide-sweeping internet censorship rulings that I’ve ever seen”.
On the other hand Google is considering the implications of the decision.
“That’s a very hard and difficult thing for Google to do – particularly if it’s at risk of being held legally liable if it gets it wrong in some way.
“Normally we would think whoever is publishing the information, they have the primary responsibility – Google just helps us to find the things that are online.” Wales added.
On Tuesday, a top EU court ruled that Google must remove search results at the request of ordinary people in a test of the so-called “right to be forgotten”.
Google said the ruling was “disappointing”.
In the Guardian, journalist James Ball described the ruling as “either an eerie parallel with China’s domestic censorship of search results, or a huge incentive for tech investment to get the hell out of Europe”.
