A 2026 decision in the District of Columbia set a tiered framework for modern attachments and short messages. It is the most practical guidance available.

A cloud link pasted into an email is not an attachment, and treating it like one is how productions fall apart. The linked file lives somewhere else, it may have changed since the email was sent, the version the recipient opened may not be the version sitting there now, and the parent-child relationship that review platforms depend on does not exist in the data.

In July 2026 a court in the District of Columbia addressed this directly in an MDL and produced the most usable framework so far. Parties must set production parameters for instant and text messages up front rather than arguing about them later. For hyperlinked documents the court adopted a tiered approach: automatic production where only a few documents are linked and collection is technically feasible; targeted requests for larger sets; and a meet-and-confer where automatic collection is not possible at all. Family relationships are preserved where the platform supports automatic collection and the linked set is small. The receiving party gets a validation process — random sampling — to confirm substantial completeness.

Why the tiering is the right answer

The all-or-nothing positions both fail. Demanding every linked document produced as a family member is often technically impossible and always expensive. Producing none of them leaves holes in the record that nobody can explain at a deposition. The tiered approach matches the obligation to what the platform can actually do, which is the only version that survives contact with the data.

Pro-Legal Services builds productions to that standard. We handle ESI processing, defensible production, Microsoft 365 and Google Workspace collection, Teams and Slack data collection, and load-file preparation for Relativity, RelativityOne, Everlaw, DISCO and our own Questa platform, for law firms and corporate legal departments across Washington DC, Maryland and Virginia.

What to negotiate at the Rule 26(f) conference

• Whether hyperlinked documents are produced automatically, on request, or by agreement — and the threshold that moves a set from one tier to the next.
• Which version of a linked file is produced: the version as of the send date, the current version, or both.
• Whether family relationships will be preserved, and an acknowledgement of where the platform cannot support it.
• Production parameters for instant and text messages — threading, time windows, participant fields — agreed before collection rather than after.
• A validation method. Random sampling is cheap, it is now judicially endorsed, and it ends the substantial-completeness argument before it starts.
• Whether clawback runs under a protective order or under the rule, which the court in this matter treated as a real choice rather than a formality.

Doing it in the collection, not the production

Most of this is decided by how the collection is configured, weeks before anyone opens a review platform. If the collection does not capture link targets at the time it runs, no amount of processing recreates them later. That is why we scope hyperlink and short-message handling at intake, in writing, with the production specification attached.

We have been running defensible productions since 1999. The data sources change every few years. What does not change is that the arguments you lose are the ones you did not have at the beginning.
