# Legal Dual Use
**Domain:** Deep Time / Law / Institutional Affordances
**Doc Type:** Canonical Wiki Entry
**Maturity:** Developed
**Evidence / Concept Status:** Corpus synthesis
## Definition
**Legal Dual Use** is the capacity of a legal mechanism created for one domain to govern a materially different domain without rebuilding the underlying administrative machinery.
## Why It Matters for Deep Time Continuity
Notice, registries, identity checks, fingerprints, licensing, takedown, custody, and succession can be repurposed when new entities enter existing categories.
## Existing Architecture / Evidence
Legal systems routinely reuse administrative machinery across domains.
## Deep-Time Continuity Analysis
Deep-time analysis asks what the mechanism could do under a new ontology, not only why it was originally enacted.
## Ground-to-Orbit Context
[[articles/From Starbase to Orbit|From Starbase to Orbit]] supplies a present-day cross-domain case. Municipal authority over temporary launch closures can be expanded by redefining “space flight activity” to include manufacturing, testing, and training; a communications licensing framework can extend across orbital servicing, surface operations, and transit. The legal machinery remains recognizable while its operational domain widens.
[[wiki/Ground-to-Orbit Infrastructure Continuum|Ground-to-Orbit Infrastructure Continuum]] uses this capacity without treating it as proof of concealed intent. The relevant evidence is the enacted or proposed control surface, its scope, and the actions it authorizes.
## Evidentiary Boundary
Dual use does not establish dual intent.
