Overview#
A prosecutor building a serious organised crime case needs to file a watertight brief. The evidence runs to thousands of pages across multiple investigations. Drafting from scratch would take a week. Manual citation checking is error-prone. Getting redactions right the first time is critical, one inadvertent disclosure could compromise an ongoing operation.
The Briefing Partner generates an AI-assisted initial draft grounded in the actual evidence, verifies every citation automatically, proposes redactions for PII and operationally sensitive material, and produces a signed, court-ready document with a verifiable chain of custody. The prosecutor's job becomes review and refinement, not construction from scratch.
Key Features#
- Multi-model AI brief generation with evidence grounding and reproducibility.
- Automatic citation verification with URL checking and content hash validation.
- Statutory element analysis with charge code databases and confidence scoring.
- AI-powered redaction with PII detection, operational security risk assessment, and alternative text generation.
- Jurisdiction-specific templates for federal and state courts.
- PDF and DOCX export with digital signatures and chain of custody logging.
- Mobile-optimised export with session-based security policies.
- Model version tracking and seed-based generation for reproducibility.
Use Cases#
Prosecutors generate initial brief drafts from investigation evidence with AI assistance, using evidence-first drafting that ensures every assertion is grounded in available material rather than assertion.
Legal teams verify citation coverage and integrity before court filing, catching broken references and missing sources at scale rather than through manual spot-checks.
Disclosure officers export court-ready documents with cryptographic integrity verification, providing defence counsel with documents whose authenticity can be independently confirmed.
Pre-trial review teams use statutory element analysis to ensure all required legal elements are addressed before filing, reducing the risk of procedural challenges on completeness grounds.
Integration#
Integrates with investigation and evidence domains for source material, court filing for submission workflows, and case management for contextual brief generation.
Open Standards#
- OAuth 2.0 and JWT Bearer Token: Token-based authentication protects typed, auditable read and write workflows across the platform.
- SHA-256 (NIST FIPS 180-4): Content hashing is applied to every exported document and to the Merkle root computation that covers all cited evidence hashes, providing tamper-evident integrity verification for court-ready exports.
- HMAC (RFC 2104): Document exports are digitally signed using HMAC-SHA-256, with the signature covering the file hash, Merkle root, and signer identity to produce a verifiable chain of custody.
- Office Open XML (ECMA-376 / ISO/IEC 29500): Brief documents are exported in DOCX format, allowing direct opening, review, and collaborative editing in any compliant word-processing application.
- JSON (RFC 8259): All internal data serialisation, export payloads, audit trail entries, and mobile-optimised exports use JSON, including the structured chain of custody metadata embedded in each export record.
- RFC 4122 (UUID): All brief documents, sections, citations, redaction proposals, and export records are identified by universally unique identifiers generated to the version-4 random UUID specification.
- ISO 8601: Timestamps on brief creation, audit trail entries, chain of custody records, and export metadata are formatted as ISO 8601 strings, ensuring unambiguous temporal ordering for evidential purposes.
- OAuth 2.0 / JWT (RFC 6749 / RFC 7519): Access to all briefing operations is gated by bearer-token authentication; JWT claims carry the organisation and user identity used for role-based access control on every query and write workflow.
