Technical Special Masters and AI: Resolving Algorithmic and Source-Code Disputes

Machine-learning systems break the assumptions behind ordinary discovery. A technical special master gives courts a way to examine models, training data, and outputs that the rules were not built to reach.

Litigation involving artificial intelligence is no longer a frontier. Copyright claims over training data, trade-secret claims over model weights, employment and lending claims over automated decisions, and product claims over generative outputs are now routine. What is not routine is the discovery they require. Machine-learning systems break several assumptions baked into ordinary discovery practice, and that is precisely where a technical special master earns the appointment.

Why AI disputes resist conventional discovery

A traditional document production assumes the relevant facts live in stable, reviewable files. Modern AI systems do not cooperate. Three features in particular create friction:

• Non-determinism. The same prompt can produce different outputs, so a single screenshot rarely proves what a model ‘does.’ Reproducibility must be established, not assumed.
• Opacity. A model’s behavior is encoded in millions of parameters, not in human-readable rules, so explainability requires structured testing rather than mere code review.
• Scale and provenance. Training corpora can span billions of records drawn from many sources, making it hard to answer the seemingly simple question of what went in.

What a neutral actually examines

A technical special master can structure the examination so the court gets answers without either party having to expose its crown jewels or drown the docket. In an algorithmic dispute, that work commonly includes reviewing the source code and training pipeline under a protective order; designing reproducible test protocols that probe the model’s behavior on agreed inputs; tracing the provenance of disputed training data; and evaluating the parties’ competing measurements of accuracy, bias, or copying. The master then reports findings in plain terms, reserving questions of law to the court.

Protecting trade secrets and the record at once

Model weights, architectures, and data pipelines are often a company’s most valuable assets. A neutral can inspect them in a controlled environment and report only what the court needs, which keeps the proprietary material out of an adversary’s hands while still giving the bench a reliable factual foundation. That dual protection — of the secret and of the record — is difficult to achieve through party-to-party discovery alone.

Framing the order for an AI matter

Because the technology evolves quickly, the appointing order should fix the questions to be answered rather than the tools to be used, and should anticipate the need for a controlled testing environment. A well-drafted order lets the master adapt methods to the system at hand without relitigating scope at every turn.

Courts facing an algorithmic or source-code dispute do not have to choose between technical depth and judicial control. A neutral supplies the first while preserving the second. Chambers and counsel are welcome to inquire about scope and availability.
