The smoking gun in the recycle bin

Microsoft says it has found the 'smoking gun' in their case against former executive Kai-Fu Lee, who left the software giant to join Google. According to court papers, the file was recovered from Lee's recycle bin on his computer.

The document indicates Google foresaw possible litigation in hiring Lee to head its China operations. It could bolster the software titan's claim that by taking his new job, Lee would be breaking a contract signed with Microsoft, and that Google has been encouraging Lee to violate that contract

Microsoft sued Lee and Google last month saying Lee had broken his one-year non-compete clause.
