It's not often that search engine use gets expanded as a result of a court ruling, but the U.S. Court of Appeals for the Second Circuit ruled this month that federal judges can now use the Internet to confirm their intuitions about the details of a case they're hearing.
Search Engine Land pointed the case out to me. In the case, US v. Bari, U.S. District Judge Denny Chin used Google and then later convicted the defendant, Anthony Bari and sentenced him to 12 years for bank robbery. Bari appealed because of the judge's Internet use.
So now the question is likely to become one of how a judge can use the Internet, since the question of whether a judge can use the Internet has been settled.
