Decision Infrastructure and Relativity
How Decision Infrastructure complements eDiscovery and evidence review in the legal technology stack.
Why this is not a replacement relationship
Relativity is a powerful platform for discovering, analyzing, and reviewing evidence. Decision Infrastructure does not replace it — it adds the runtime layer that governs whether the consequential actions taken from that evidence remain admissible at the moment they execute.
They sit at different layers of the same stack: Relativity operates at the discovery and evidence-review layer; Decision Infrastructure operates at L6 — the governance layer between decisions and their consequences.
What Relativity Does Well
Relativity is a broad eDiscovery and evidence platform. Within a legal team it can:
- process and host large volumes of evidence
- search, filter, and analyze documents at scale
- support review workflows and coding
- apply analytics and AI-assisted review
- produce and manage discovery sets
What Happens After Relativity?
Relativity surfaces and reviews the evidence. Decision Infrastructure validates admissibility before the consequential actions taken from that evidence become real.
Examples include:
- discovery review
- production decisions
- privilege review
- regulatory response
- litigation preparation
The question shifts from “what does the evidence show?” to “what action may be taken because of it — and may it execute now?” — and that question is resolved at L6.

What Decision Systems Fix — and What They Don’t
L5 · Decision Systems
Decision Systems
What they fix
- Structured decisions
- Decision tracking
- Traceability
- Repeatability
What they don’t answer
- Should this decision exist?
- Is it valid under current constraints?
- Can it control execution?
- Will it produce evidence?
Core question: “What decision was made?”
L6 · Decision Infrastructure
Decision Infrastructure
What it adds
- Decisions validated before execution
- Policy enforced at runtime
- Human and AI accountability
- Evidence across the lifecycle
- Runtime admissibility
Core shift
From structuring decisions to governing whether decisions are valid, executable, and accountable.
Core question: “Is this decision valid, executable, and defensible?”
Most platforms optimize decisions. Very few govern them.
L5, L6, and L7: Different Roles
Relativity surfaces the evidence; Decision Infrastructure governs the act taken from it. The distinction is not a feature gap — it is a different layer of the stack.
L5 produces and routes decisions.
L6 governs whether those decisions remain admissible at execution.
L7 learns from the outcomes of governed execution.
Why Trusted Decision Intelligence Requires L6
Decision Systems determine what should happen. Decision Infrastructure determines whether it may happen now.
Decision Intelligence learns from outcomes. If those outcomes were never validated at execution, the learning is built on actions that may never have been admissible.
Decision Intelligence is not the input to Decision Infrastructure. It is the output of governed execution.
Frequently Asked Questions
Is Decision Infrastructure an eDiscovery tool?
No. It does not process, host, search, or review evidence. Relativity does that at the discovery and evidence-review layer; Decision Infrastructure is the runtime governance layer (L6) that governs whether the consequential actions taken from that evidence remain admissible at execution. They are complementary layers.
Does it replace evidence review?
No. Relativity surfaces and reviews the evidence; Decision Infrastructure governs whether the actions taken because of it may execute now — admissible, authorized, compliant, and evidenced at the moment they occur. It governs the act, not the review.
What happens after evidence is reviewed?
Reviewed evidence becomes the basis for a consequential action. Decision Infrastructure revalidates, at the commit boundary, whether that action is still admissible under current authority, policy, and constraints — and returns Allow, Hold, Deny, or Escalate with evidence before it executes.
Is it a Relativity replacement?
No. It does not discover, host, or review documents. It governs the admissibility of actions at the commit boundary — independent of, and portable across, the systems that surface the evidence, including Relativity.
Can it run alongside Relativity?
Yes. Relativity surfaces and reviews the evidence; Decision Infrastructure governs whether each action taken from it is admissible at execution and captures independent evidence. The discovery layer surfaces; L6 governs the act.
Why does Decision Intelligence depend on L6?
Decision Intelligence (L7) learns from outcomes. Without L6, it may learn from legal actions that were never admissible. With L6, it learns only from governed execution — making the resulting intelligence trustworthy.
