Structured legal investigation with deterministic classification
Jurisdiction-aware evidence investigations across BAILII, legislation.gov.uk, and jurisdiction-specific databases — legal classification based on source authority type, not probability scores.
BAILII citation verification
Every UK neutral citation is verified directly against BAILII. Confirmed citations receive a VERIFIED badge — unconfirmed receive LIKELY or UNVERIFIED so you know exactly what to check manually.
3 jurisdictions — correct sources
UK (BAILII, legislation.gov.uk), Nigeria (NWLR, LPELR), and US (federal reporters, USC, CFR) — each with its own citation patterns and authority hierarchy. No cross-jurisdiction borrowing.
Deterministic legal classification
Classification derives from source authority type — statute > case law > regulator > none. Three outcomes: Outside reserved activities, Reserved activity likely, or Uncertain legal position — returned when evidence is insufficient, not speculative.
Binding vs persuasive flags
Every case is tagged binding or persuasive for your jurisdiction. You always know the authority hierarchy before you rely on a case in submissions or advice.

Questions from legal professionals
No. Deepheem replaces the manual preliminary research before you open your database. Use Deepheem to identify relevant cases quickly — then deepen and verify on Westlaw or LexisNexis.
United Kingdom (BAILII, legislation.gov.uk), Nigeria (NWLR and LPELR citations, judiciary.gov.ng), and the United States (federal court reporters, USC, CFR) — each with jurisdiction-specific citation formats and source authority hierarchies. Legal classification never borrows sources across jurisdictions.
Legal classification in Deepheem is deterministic — based on the authority type of retrieved sources (statute, case law, or regulator). When retrieved evidence is insufficient to support a positive classification, the report returns UNCERTAIN_LEGAL_POSITION rather than speculating. This means the investigation could not confirm the activity is either clearly inside or outside reserved legal activities — not that a risk exists. The three possible outcomes are: OUTSIDE_RESERVED_LEGAL_ACTIVITIES, RESERVED_LEGAL_ACTIVITY_LIKELY, or UNCERTAIN_LEGAL_POSITION.
When a citation is identified, Deepheem constructs the BAILII URL and verifies it directly against the database. Citations confirmed on BAILII receive a VERIFIED badge. Those that cannot be confirmed receive LIKELY or UNVERIFIED — so you know exactly what to check manually before relying on a case.
No. Deepheem outputs are evidence-based investigation findings and do not constitute legal advice. They are suitable as a research input — all findings and citations must be independently verified by a qualified legal professional before reliance, court submission, or professional advice.
Your queries and reports are never used to train models. Data is encrypted in transit and at rest. Business plan customers can request region-pinned storage for regulatory compliance requirements.
