Not yet! Luckily, it's sitting in Mt. Gox safe and sound till the liquidators get it back so that they ... or something like that.
Interesting post on Reddit just now by MtGox on that topic:
WeAreMtGox:
"
The communications from the liquidator wrongly creates an impression that we are withholding information and account access without any proper lawful basis and otherwise failing to co-operate with the liquidator. To the contrary, we have communicated our willingness to co-operate with the liquidators of Bitcoinica LP (In Liquidation) as far as we can lawfully do so.
Before we can release the confidential and highly sensitive information sought by the liquidators, they must first provide certain basic verificatory evidence to establish that they are entitled to the information. So far, they have not."
