Legal opinions sometimes use Google searches as evidence

This Declan McCullagh story, from, describes several cases in which judges used Google searches to support their ruling opinions. The incidents range from testing whether ‘Johnny’s sauce’ is too common a phrase to be copyrighted to researching the effects of secondhand smoke on children. Another one that struck me was a court’s decision that a Sri Lankan film maker who claimed to be famous must not be, since his name returned no hits in a Google search.
