At a meeting in June, the Standing Committee Rules of Practice and Procedure approved amendments to the federal rules that address electronic discovery. The changes are now available in a pdf document on the US Courts "Federal Rulemaking" page.
The proposed amendments will next be considered by the Judicial Conference in September, and will then be transferred to the Supreme Court. Further information is available at the Electronic Discovery Law website.
Even if the rules are approved, they probably will not become effective until December 1, 2006. In the meantime, the amendments, comments, and notes will certainly give you some new ideas for conducting electronic discovery in ongoing litigation.
