Nat’l Economic Research Assocs., Inc. v. Evans, LECG Corp., 21 Mass. L. Rptr. 337 (Mass. Super. Ct. Aug. 3, 2006) is a fascinating case in various ways, and just came to my attention. Apparently, when a user views mail on yahoo, it takes a screenshot of the mail which is stored on the hard drive. While it’s not as easy to later access as a temp file, apparently they reside on the hard drive. I couldn’t find the opinion on line, but it was on westlaw.

Anyone who uses public computers or employer-owned laptops to communicate “in confidence” should examine this issue. I’m not sure it’s accurate, but the court clearly stated that Yahoo, alone, left these ghost emails!
