It is about the recent news on google inc.. What does "carte blance" mean in the following excerption? Thanks!
"We will always be subject to government subpoenas, but the fact that the judge sent a clear message about privacy is reassuring," Google lawyer Nicole Wong wrote on the company's Web site Friday night. "What his ruling means is that neither the government nor anyone else has carte blanche when demanding data from Internet companies."
"carte blanche" is from French and means "white card" or, more appropriately in this case, "blank ticket". The image is that if you have a blank ticket, you can write whatever you like on it.
If you have "carte blanche", it means you have the power or the authority to do whatever you like. Wong is saying that the court's ruling shows that the US government cannot do anything it likes; its authority is kept in check by the courts.
