Google Executive Chairman Eric Schmidt on Wednesday said the search company would fight legislation aimed at shutting down access to file-sharing websites that offer pirated content.

"If there is a law that requires DNSs [domain name systems] to do X, and it's passed by both houses of Congress and signed by the president of the United States and we disagree with it, then we would still fight it," Schmidt told reporters at a London conference.

"If it's a request, the answer is we wouldn't do it. If it's a discussion, we wouldn't do it," Schmidt added.

"I would be very, very careful if I were a government about arbitrarily [implementing] simple solutions to complex problems," Schmidt said.
