01
The trigger is judged in hindsight
Litigation is reasonably anticipated when a demand letter arrives, when a dispute reaches counsel, or when the company decides to sue; a court fixes the date later, looking backward. The hold has to reach systems that delete on their own: chat platforms, phone backups and a departed employee's mailbox.
02
Review is priced at the protocol
Email threading and deduplication remove the copies. Technology-assisted review, accepted by federal courts since 2012, trains on the lawyers' own coding decisions and is validated by sampling against a recall rate agreed in advance. The protocol fixing custodians, date ranges and search terms is where the bill is set.
03
Rule 37(e) has two tiers
If electronic information that should have been kept is lost and cannot be restored, a court finding prejudice may order measures no greater than needed to cure it. Only a finding of intent to deprive permits an adverse inference, dismissal or default. Lost paper falls under the court's inherent authority.
04
The data map is the first exhibit
Opposing counsel asks for it at the Rule 26(f) conference, and a Rule 30(b)(6) deposition of the company's systems witness tests it. A current map of mailboxes, chat tools and shared drives, with each retention period attached, lets a hold be scoped in days and defended years later.
05
Foreign law rarely excuses production
A US court usually orders production despite a foreign blocking statute, on a comity analysis, while the foreign regulator can penalize the transfer. GDPR Article 49 permits a transfer needed to establish or defend a legal claim, read narrowly, so the answer is in-country review and a narrowed, pseudonymized export.
06
Proportionality has six factors
Since 2015, Rule 26(b)(1) no longer asks whether a request is reasonably calculated to lead to admissible evidence. It asks whether discovery is proportional to the needs of the case, weighing the stakes, the amount in controversy and the parties' relative access to the information, among six listed factors.
