The Mt. Gox Bitcoin exchange may still be reeling from the botnet discovery that ruined its business, but it just got a big reprieve. A US court has approved Mt. Gox's Chapter 15 bankruptcy protection, preventing creditors who sued the company from seizing any American assets (including servers) or pressing for evidence. The exchange can also chase down any funds it needs to repay its debts and, if necessary, file lawsuits of its own.
