Executive Summary
Obtaining civilian records for court-martial requires the defense investigator to identify material evidence, the correct custodian, retention deadlines, lawful production requirements, and the facts counsel needs to use R.C.M. 703.
Civilian businesses, organizations, custodians, and witnesses may possess evidence that is material to a court-martial, but the defense may not be able to obtain that evidence through a voluntary request.
DI-144 explains how investigators can define the precise evidence needed, identify the correct custodian, determine location and retention risk, document preservation efforts, and distinguish voluntary production from consent or formal legal process.
The publication also emphasizes service, objections, return, authentication, and chain records. Its practical example involves a civilian business with relevant video that refuses voluntary release. The defense identifies the custodian and retention deadline, preserves the record, and gives counsel the facts required to seek proper process under R.C.M. 703.
The purpose is to prevent potentially important civilian evidence from disappearing while creating a source-based investigative record that supports timely legal action.
DI-144 explains how military defense investigators identify and preserve civilian records and witnesses for trial by documenting materiality, the correct custodian, retention risk, lawful access routes, production requirements, and unresolved obstacles under R.C.M. 703.
Who Should Read This Publication?
Military Defense Counsel
Use the investigative record to evaluate materiality, preservation needs, witness and record production, objections, authentication, deadlines, and whether formal process under R.C.M. 703 or other authority is required.
Defense Investigators
Identify the correct custodian, record retention, fees, lawful access route, preservation status, service and return information, and every unsuccessful effort or access restriction.
Service Members
Understand why civilian evidence may require early identification and preservation and why the defense team may need formal legal process even when the evidence clearly exists.
Civilian Record Custodians and Potential Witnesses
Understand that defense investigators may seek to identify and preserve relevant records or testimony while counsel determines the appropriate voluntary or formal production method.
Families
Understand why apparently simple evidence—such as a business surveillance video—may require immediate preservation and careful coordination before it can be obtained and used in a military case.
