Lexical (FTS5/BM25) search over the statute corpus (Constitution, codes, RA, PD, EO). Information retrieval, not legal advice. Results carry structured citations; below confidence threshold the tool reports insufficient corpus coverage rather than guessing.

Pagination: use offset to page; check hasMore/nextOffset. Use domain to narrow results.

Lexical (FTS5/BM25) search over the case corpus (SC, CA, SB, CTA decisions). Information retrieval, not legal advice. Results carry structured citations; below confidence threshold the tool reports insufficient corpus coverage rather than guessing.

Pagination: use offset to page; check hasMore/nextOffset. Use court to narrow results.

Lexical (FTS5/BM25) search over the administrative issuance corpus (BIR first, Phase 3). Information retrieval, not legal advice. Below confidence threshold it reports insufficient corpus coverage rather than guessing.

Pagination: use offset to page; check hasMore/nextOffset. Filter by agency or issuanceType.

Return the exact text of a provision (e.g. Civil Code Art. 1156) with its current status. Version-aware: reports amended/repealed/superseded status when the corpus tracks it.

Return a case by citation (e.g. 'G.R. No. 238875') with metadata and the first passages of the decision.

Return an issuance by agency + reference number (e.g. 'BIR' / 'RMC 85-2023') with metadata and the first passages of the document.

Resolve a citation against the corpus and return the exact matching text. If the citation cannot be resolved, it returns a clear 'cannot validate' verdict — it never fills in plausible text. Use this before relying on any AI-generated citation.

Enumerate the 15-domain compliance taxonomy (ADR-000 core + ADR-004 expansion) with corpus refresh timestamps, so callers can check freshness before trusting retrieval results.

Given a case citation (G.R. No.), list the statutes that case cites, resolved against the corpus. Only citations that resolve to an ingested statute are returned.

Given a case citation, find other cases in the corpus that cite at least one of the same statutes (shared citation neighborhoods). Useful for identifying lines of jurisprudence.

List the amendment log for a statute (amending law, affected provision, effective date). Use with get_provision to confirm the current text of an amended provision.

Show every recorded version of a provision, ordered by effective date (valid_from). Confirms whether the current text differs from an earlier version.

Show which statutes a statute cites (dependencies) and which statutes cite it back (dependentOn), from corpus-grounded law→law edges.

List every citation a case makes (statutes and other cases), as recorded in the citation graph. Citations that could not be resolved against the corpus are not listed.

Find corpus references to the Implementing Rules and Regulations (IRR) of a statute — citations mentioning IRR that resolve to the statute, with the citing cases.

Curated cross-domain references (from the domain registry) for the statute's domain, plus statute→statute citation edges from the corpus graph.

Deterministic prescriptive-period calculator under Civil Code Arts. 1144-1149 (RA 386). Pick the class of action to get the codal period in years, the exact article, and — if a cause-of-action date is given — the computed deadline. The computation is arithmetic over the cited articles; verify the codal text with get_provision or cite_validate before relying on it, and note that interruption (Art. 1155) can extend the deadline in practice. Not legal advice.

Deterministic filing-deadline calculator under the Rules of Court. Applies Rule 22 computation of time (exclude the first day, include the last; last day on a Saturday, Sunday, or legal holiday runs to the next working day) to the common reglementary periods (Rule 37, Rule 41, Rule 45, Rule 65). Pass legal holidays as ISO dates — they are declared per year by proclamation, so never assume the calendar. Verify the rule text with get_provision or cite_validate before relying on it. Not legal advice.

Deterministic 13th-month-pay calculator under PD 851 (as amended by Memorandum Order No. 28 and the Rules Implementing PD 851). Computes total basic salary earned within the calendar year ÷ 12 for rank-and-file employees (pro-rated automatically for partial-year service), and returns coverage/exclusion notes plus the payment deadline (on or before December 24). Verify the rule text and current DOLE advisories with the corpus before relying on it. Not legal advice.
