Email Deduplication, What Does It Really Mean?
A recent post to the Yahoo! LitSupport group asked whether there were any published standards covering email deduplication hashing. The problem is more complicated that it appears on the surface. As several other search experts commented, the definition of a duplicate email and the actions that you take will vary based on the jurisdiction, matter issues and party demands. Under FRCP Rule 34(b), the requesting party may define the format of production within the scope of the Rule 26(b) and the terms of your Rule 26(f) negotiations. Both rules provide some exemption for duplicative productions, but there are arguments that can be made about deduplication within a custodian’s email or across all custodians.
