Ediscovery Strategy: from Legal Hold to Production without Costly Missteps

A litigation hold notice must identify the categories of information subject to preservation, instruct each custodian to suspend deletion of relevant data, describe how the custodian should identify and segregate relevant information, provide a point of contact for questions, and be confirmed in writing with a tracking mechanism for custodian acknowledgments. Under Federal Rule of Civil Procedure 37(e), a court may impose sanctions including an adverse inference instruction or case-dispositive sanctions when a party fails to take reasonable steps to preserve electronically stored information that cannot be restored or replaced. Spoliation of evidence counsel must document every step of the hold process, from the trigger event through custodian acknowledgments, since that documentation is the primary defense against a spoliation motion.

Forensic collection requires using validated tools that capture data without altering file system dates, timestamps, or metadata that a court may need to authenticate the document or establish the sequence of events that created it. Evidence preservation counsel must also address collection from mobile devices, collaboration platforms, and ephemeral messaging applications that present unique authentication and custody challenges.

Keyword filtering limits the review population to documents containing agreed-upon search terms or terms developed based on the claims, defenses, and custodians most likely to hold relevant information, and the defensibility of the approach depends on a systematic and documented process. Civil litigation evidence counsel must confer with opposing counsel in good faith about proposed search terms, negotiate over terms that are under-inclusive or over-inclusive, and document the agreement for the court's record.

A well-designed eDiscovery strategy applies early case assessment data analytics tools to the collected document population to identify communication patterns, key custodians, document timelines, and thematic clusters that reveal the strength and weakness of the client's legal position before full review. Commercial litigation counsel using early case assessment results in settlement negotiations can present a data-supported narrative demonstrating readiness to litigate, creating settlement pressure without disclosing privileged communications or attorney work product.

Predictive coding uses a machine learning algorithm trained on attorney coding decisions to classify the document population by estimated relevance, and defensibility depends on demonstrating that the training set produced a statistically valid model validated through iterative sampling. eDiscovery counsel deploying predictive coding must be prepared to disclose the validation methodology to opposing counsel and, if challenged, to the court.

Recall measures the proportion of all relevant documents identified by the review process, while precision measures the proportion of documents classified as relevant that actually are relevant, and a statistically valid sample of non-relevant documents must be reviewed to estimate the recall rate before the production is finalized. If the recall rate falls below the target threshold the training process must continue until the model's performance improves. Data privacy litigation counsel overseeing quality control must document the sampling methodology, sample sizes, recall and precision calculations, and corrective actions taken in response to sampling results.

Document production typically requires native format with a metadata load file, TIFF or PDF with a corresponding text file, or a combination specified by the court or agreed by the parties, and the specifications must be confirmed before processing to avoid having to reprocess and re-produce documents in a different format. Protective order counsel must confirm that the agreed confidentiality order covers the metadata fields included in the production load files, since those fields can reveal sensitive organizational information.

A clawback agreement negotiated under Federal Rule of Evidence 502(d) and incorporated into a court order allows the producing party to retrieve inadvertently produced privileged documents without waiving attorney-client privilege or work product protection, and the court order makes the non-waiver binding on all parties and enforceable in other federal and state proceedings. Commercial litigation counsel must ensure the order specifies the clawback procedure, the timeline for returning inadvertently produced documents, and the dispute resolution mechanism if the parties disagree about whether a clawback was timely.
