Court: Web contracts can't be changed w/o notice

RZG writes: The U.S. Court of Appeals for the Ninth Circuit ruled on July 18th that contracts posted online cannot be updated without notifying users. "Parties to a contract have no obligation to check the terms on a periodic basis to learn whether they have been changed by the other side", the court wrote. This ruling has consequences for many online businesses, who took for granted their right to do this. (See for example item 19 in Google's Terms of Service)
