Changelog

​

New: the US Virgin Islands and American Samoa

• The Virgin Islands holds the Virgin Islands Code (12,937 sections, cited V.I. Code Ann. tit. 14, § 1, an unofficial copy with its source link withheld), the Virgin Islands Rules and Regulations (181 sections, from the Department of Planning and Natural Resources) and 900 court rules in 22 sets.
• American Samoa’s Code, Constitution and court rules are read from the American Samoa Bar Association’s site, and its Administrative Code from the Office of the Secretary of American Samoa.
• Citations such as Am. Samoa Code Ann. § 46.4810, A.S.C.A. § 46.4810, Am. Samoa Admin. Code § 4.2126, 12 V.I. R. & Regs. § 803-52 and V.I. R. Civ. P. 6-3 resolve.
• Both are kind: "territory" on GET /us/statutes/coverage.

​

New: state register notices

​

New: a flag on answers that are not the exact section you cited

• A register citation resolves only on an exact volume and page, a range that contains the page, or an exact filing identifier.
• A citation that resolved to nothing before and resolves now only through one of these readings is not pinned to rank 1 by search.

​

New: county and district trial-court rules

​

Added to existing corpora

• Maryland regulations: all 36 titles of COMAR, 29,433 sections, where 23 titles were held before.
• Missouri court rules: 1,536 sections. Missouri is no longer listed as a gap.
• Vermont court rules: 833 rules, cited Vt. R. Civ. P. 26 and Vt. R. Evid. 803, with their source link withheld. Every jurisdiction now carries court rules.
• Federal local court rules: recounted at 6,234 rules (5,936 in force) from 52 courts in 112 rule sets. The 32 district sets cover 33 districts, because the Southern and Eastern Districts of New York share one set.
• Professional-conduct and bar rules for California, Oregon, Virginia, the District of Columbia, Georgia, Idaho, Florida and Texas are read from the bar association’s own site. See Where bar associations supply the text.
• Court rules: West Virginia’s lawyer and judicial disciplinary rules, Florida’s admissions rules, Montana’s Code of Judicial Conduct and Sentence Review Division Rules, and the Massachusetts juvenile and probate families under their own names (Mass. Juv. Ct. Care & Prot. Rule 5).
• Nevada ADR rules are split by instrument: Nev. R. ADR n is now the General Provisions only, and arbitration and mediation are Nev. Arb. R. n and Nev. Med. R. n.
• Guam and the Northern Mariana Islands: court rules are held one rule per document, except six Guam sets and 21 Northern Mariana Islands sets that are held as one document per set.
• Pennsylvania: the Constitution’s Schedule is served apart from Article V, and 54 sections of the unconsolidated statutes (35 P.S. ch. 780) are held.
• Puerto Rico: Reorganization Plan No. 2-2011 and the 1930 Civil Code (1,811 articles, all repealed).
• Maine carries the MaineCare manual and New Hampshire the Department of Environmental Services rules.

​

Not covered

• State session laws are served by their own endpoints and cover the 2025 sessions only. See State Session Laws.

​

Changed

• The OpenAPI corpusType enum now carries 23 tokens: the 22 on Corpus types and USC_ANNUAL, a retired GPO edition of the US Code that is not a token to search. state accepts 56 jurisdictions.
• The statutes, regulations, court rules and constitutions totals on API Coverage were re-measured: 2,010,030, 1,496,499, 71,880 and 13,016.

​

New: federal local court rules

• Citations such as 3d Cir. L.A.R. 26.1, Fed. Cl. R. 59, Mil. R. Evid. 803 and S.D.N.Y. Local Civ. R. 7.1 resolve through /us/statutes/resolve.
• A bare number that does not name a court, or a district with separate civil and criminal sets that the citation does not name, is refused rather than guessed.

​

New: Guam and the Northern Mariana Islands

• Citations such as 9 Guam Code Ann. § 16.10, 2 N. Mar. I. Code § 7222 and 165 N. Mar. I. Admin. Code § 165-30.1-101 resolve.
• Several court-rule sets are held as one document per set, so a citation to one rule in those sets returns the whole set. See State and territory coverage.

​

Added to existing corpora

• Nebraska: about 9,400 sections that were missing, among them the comma-numbered sections (the DUI statute 60-6,197, the State Tort Claims Act 81-8,209) and the Uniform Commercial Code.
• Maryland court rules: 277 rules that were missing, among them the judicial-conduct rules (Title 18) and the attorney professional-conduct rules (Title 19).
• Rhode Island: sections that were missing from 1,065 chapters, and 47 duplicate sections removed.
• Texas: the Revised Civil Statutes (Vernon’s), 266 articles, and the missing Code of Criminal Procedure articles, among them art. 38.22.
• Court rules: Nevada, Ohio, Mississippi and Montana gained rules a parser had dropped; Pennsylvania gained its unconsolidated acts, and the Pennsylvania Constitution’s Schedule is now separate from Article V.
• Citation resolution: about 250 more citation forms are read, including publisher abbreviations, parallel citations and each state’s own court-rule style.

​

Changed

• The OpenAPI corpusType enum now carries 22 tokens, and state accepts 54 jurisdictions.

​

New: search state session laws

• It searches the enacted text. Language an act strikes out is never searched and never appears in a snippet.
• Ranking is keyword relevance, not meaning, so a question has to share vocabulary with the act. Each result says how it matched (matchType, matchedBy); there is no “no good match” flag.
• Filters: jurisdiction, session, series, instrumentType, approvedFrom, approvedTo. limit is 1 to 25 and offset plus limit reaches at most the 60 best matches.
• An empty result is charged. A request that fails validation is a 422 and is not charged.

​

Changed

• series and instrumentType on GET /us/session-laws/list now take several values (repeat the parameter; they combine with OR). A value outside the published list is a 422 and is not charged, where it used to return an empty, charged page. A cursor issued before this change still resumes.
• The OpenAPI document now publishes the allowed values of every field that takes one value or a list (state, corpusType, source, fields, actStatus and others) on each value rather than on the field as a whole. Generated clients and the playground offer them as pickers, and a list is no longer rejected by a strict client. actStatus is now published on POST /us/statutes/count and GET /us/statutes/divisions as well.

​

New: state session laws

• GET /us/session-laws/{sessionLawId} also takes a citation in place of the id, for 2 more credits.
• GET /us/session-laws/list requires jurisdiction and filters by session, series, instrument type, approval date and effective date.
• Each law carries its approval date, effective dates, veto outcome, sources and, in 11 jurisdictions, the code sections it changed.
• Laws with a known text defect are returned with textStatus: "withheld" and the reason; their text is not served.
• POST /us/session-laws/batch returns up to 50 laws by id or citation in one call; includeBody: true adds each law’s first page of text at 6 credits per page.
• GET /us/session-laws/changes is a cursor feed of every law served, corrected, withdrawn or merged.
• GET /us/statutes/section/{actId}/enactments lists the session laws a publisher’s tables print against a code section, in CA, DC, HI, KY, MO, MS, NE, UT and WA.
• POST /us/statutes/resolve recognises a state session law citation that names no code section: the response carries matchedCorpus: "session_law" and a sessionLaw block (resolved stays false, section stays null). No extra charge.
• GET /us/statutes/coverage gains a sessionLaws block per jurisdiction: sessions with status, counts, the series and instrumentTypes held and the span of approval dates.

​

Three more corpora you can walk as a tree

• corpusType=CONSTITUTION lists the Preamble, the seven articles and the 27 amendments, in reading order. Pass one back as article (article=Amendment XIV) for its sections.
• corpusType=STATE_CONSTITUTION&state=nm lists a state constitution’s articles the same way.
• corpusType=FEDERAL_RULES lists the rule sets (FRCP, FRE, FRCrP, FRAP, FRBP, Supreme Court Rules and the FRCP supplemental rules), and code=frcp lists the rules in one. The same rule sets are also published as an appendix to the U.S. Code, and those are listed as their own sets (uscapp_t28a_fre), so no rule appears twice under one heading.

• {"corpusType": "STATE", "state": "ny", "code": "ny_jud", "article": "2"} searches one article of a New York code.
• {"corpusType": "FEDERAL_RULES", "code": "frcp"} searches the Federal Rules of Civil Procedure, and code=uscapp_t28a_fre the Federal Rules of Evidence as the U.S. Code appendix prints them. source=frcp still covers the FRCP together with its supplemental rules; code is the finer scope.

STATE_RULES: Colorado

• 180 rules carry an amendment adopted in 2024 to 2026.
• 958 rules have not been touched by any adopted order since the compilation, so their 2023 text is the current law. The order series is contiguous with no gaps, which is what makes that statement checkable rather than a hope.
• 45 rules could not be updated automatically. They serve their 2023 text and say so in sourceNote, naming the order, its adoption date and its effective date. 🔴 Read that field before relying on one of these; they are labelled, not silently stale.
• 11 rules are suspended, not in force. The Colorado Rules of ICWA Procedure (Chapter 28.3) were adopted effective 2024-01-01 and suspended by the Supreme Court on 2025-11-06. They carry actStatus=suspended and are served for reference.

​

STATE_AG_OPINION: Montana and North Carolina

• Montana, 3,527 opinions, volumes 15 to 44. 🔴 These carry no issue date. Montana publishes by volume and prints no date on an opinion, so unlike every other jurisdiction here they do not answer an asOf query. They are reachable by citation, volume and search. Volumes 1 to 14 are excluded: the leading number on those is a page in the bound volume, not an opinion number, so there is nothing stable to cite them by.
• North Carolina, 1,106 opinions, 1976-2010. The state prints no opinion number, so these are keyed on issue date plus the official who asked.

​

STATE_AG_OPINION: seven more jurisdictions

• Alabama, 11,928 opinions, 1979 to present. The state’s own archive begins in 1979. Earlier opinions exist but Alabama does not publish them itself, so they are a stated coverage limit rather than a gap we intend to close.
• West Virginia, 151 opinions, 2007-2026. The state prints no opinion number, so these are cited by date and requester surname.
• Texas, 2,914 opinions, 1983-2026. The seven post-1983 series only. Roughly 14,800 earlier opinions sit behind paths the state restricts automated access to, so we do not hold them.
• Massachusetts, 529 opinions, 1968-1993, split out of the Attorney General’s annual reports. Only that era carries citable opinion numbers.
• Mississippi, 520 opinions, 2020-2026. The state’s pre-2020 opinion database is no longer published anywhere by the state.
• Nevada, 41 opinions, 2017-2026, the modern per-opinion era only. The bound annual compendia are not yet split into individual opinions.
• District of Columbia, 37 opinions, 1982-2026, formal opinions only. Advisory Neighborhood Commission letters are a different instrument and are excluded.

​

Counts corrected on this page’s coverage tables

​

STATE_AG_OPINION: 22 more jurisdictions

• Missouri runs 1962 to present. The 1933-1961 era is not served: the number printed on those opinions is a requester-alphabetical folder position, not a document identifier, so there is nothing stable to cite them by.
• Maine serves its numbered era, 832 opinions. The earlier material carries no opinion number in the state’s own archive and is not served for the same reason.
• Pennsylvania, 653 opinions, is split out of bound volumes. Its 1895-1930 volumes print no per-opinion number and are not served.
• Illinois is served from our own OCR. Roughly 1,450 of its 1,456 opinions are scans with no text layer at all, so the text you get is machine-read from the state’s page images and gated for readability before it is served. Anything that failed that gate is excluded and counted, not served degraded.

​

STATE_AG_OPINION: four more jurisdictions, and the two largest

• Arkansas lists 334 further opinions its own index carries a row for and whose document it has never published. Those are recorded as a coverage limit, not counted, so 10,295 is what we hold. They cluster in 1985-1998.
• Indiana reaches back to 1906 and publishes in two citation forms, both carried as the state prints them: numbered opinions from 1944, and page cites into the annual and biennial report volumes before that. In the scanned eras Indiana cut its bound volumes into per-opinion PDFs by page, so an opinion running past its page cut is severed in the state’s own file. We serve everything Indiana publishes, but for those the text is the opening pages. The 1960s, 1970s and 2000 onward are unaffected. Every Indiana opinion also carries the statutes it construes, the Attorney General who signed it, and the state’s own summary.
• Idaho is opinions only. The Guidelines, Certificates of Review, Annual Reports and Tables of Citations that share its feed are a different instrument and are not here. Pre-1985 opinions exist only inside annual report volumes.
• Oklahoma is deliberately 2023 onward. Its older opinions are published on a network whose publisher does not permit automated access, so we do not hold them.

​

STATE_AG_OPINION: state Attorney General opinions

• Delaware runs one numbered series and does not separate its opinion types. Only about 17 of the numbered items are substantive Attorney General opinions; the rest are FOIA opinion letters interleaved in the same numbering. Both are formal opinions of the Attorney General under Delaware law, so both are here.
• 173 of the 843 are the state’s letter recovered from a reporter print. Delaware publishes those posts in a commercial reporter’s rendering. The opinion underneath is a government work, so we remove that publisher’s citation and page marks and serve the letter itself. 150 of the 173 exist in no other form in Delaware’s archive and span 1995-2011.
• 50 further posts carry no opinion number and are excluded: press releases, job postings and notices sharing the same archive.

NLRB Board decisions: the complete archive

• 227 NLRB 427 - the publisher’s PDF contains only the case caption and no body. Two independent extractors agree, so there is nothing to serve.

Things that stay true when the number goes up

• Federal Register notices are 17,616 of the 766,073 published in the period, 2.30%, four operative classes by design. That is not notice coverage and is never described as such.
• The Internal Revenue Manual is agency procedure, not law. It is the IRS’s own instruction manual for its employees and does not bind the agency against a taxpayer.
• The adjudication corpora (FTC Part 3, NLRB, MSPB, BIA, SEC, OLC, CFPB) carry no verified doctrinal currency. goodLawStatus is unknown by design on all but the CFPB slice, and nothing here implies good-law assurance. A live corpusType=AGENCY_ADJUDICATION search returns nlrb_board_decision hits with goodLawStatus: "unknown", which is the intended answer and not a gap.
• Statutes at Large is law as enacted. It carries goodLawStatus: "unknown" deliberately and is a historical record rather than a statement of current law; for what the law says today, use corpusType=USC.

​

Resolve constitutions, court rules, and more citation forms

• US and state constitutions: U.S. Const. art. I, § 8, U.S. Const. amend. XIV, § 1, U.S. Const. pmbl., Cal. Const. art. I, § 7.
• Federal court rules: Fed. R. Civ. P. 12 (incl. a pincite like Fed. R. Civ. P. 12(b)(6)), Fed. R. Crim. P. 11, Fed. R. Evid. 702, Fed. R. App. P. 4, Fed. R. Bankr. P. 9011, and the compact FRCP 12 form.
• Annotated / prefixed federal statutes: the annotated 42 U.S.C.A. § 1983 and 42 U.S.C.S. § 1983 forms, Title 42 U.S.C. § 1983, and a doubled §§.

​

Search within a hierarchy subtree

• chapter (USC/state) and part (CFR): confine results to one or more chapters or parts, e.g. titleNumber: 42, chapter: "21" or titleNumber: 17, part: "240". Both accept a single value or a list.

​

Control what search matches and returns

• matchType: any (default) is intent-ranked hybrid search. all requires every query term to appear; phrase requires the exact phrase. Use the stricter modes when you need precision over recall.
• excerptChars: how much matching text each result carries in excerpt (default 500, range 100 to 4000). Raise it for more inline context.

​

Every result now points to its neighbors

​

Amendment provenance on statute results

​

Page deeper

​

/body can now return a structured subsection tree

• markdown: the section rendered as nested Markdown lists, one level per subsection depth.
• subsections: a tree parsed by the drafting convention ((a) subsection, (1) paragraph, (A) subparagraph, (i) clause). Each node carries its label, a pincite path (e.g. (b)(2)), a full pinpoint citation (e.g. 42 U.S.C. § 1983(b)(2)), its own text, and nested children.

​

Two new endpoints: resolve a citation, browse the hierarchy

• GET /statutes/resolve (2 credits): resolve a Bluebook citation string (42 U.S.C. § 1983, 16 C.F.R. § 444.1, Del. Code Ann. tit. 13, § 1301) straight to the exact section, confirmed, with an official source link. A pinpoint subsection resolves to the parent section and is echoed in subsection. resolved reports whether the citation is real, so it is the one-call way to verify a citation an LLM produced. See the citation recipe.
• GET /statutes/divisions (1 credit): walk the statutory hierarchy one level at a time, in statutory order. Pass the deepest level you know (corpusType, titleNumber, chapter/part, or a state code) and get the children below it, down to sections with their actId. Supports USC, CFR, STATE, and REGULATION. See the browse recipe.

​

Statute results now carry status, currency, and fuller metadata

• Status and currency: actStatus (in_force, repealed, renumbered, transferred, omitted, reserved, vacant, unconstitutional), a derived goodLawStatus (good_law / not_good_law / not_operative / unknown), currencyNote (the source’s “current through …” line), and renumberedTo / transferredTo pointers.
• Fuller hierarchy: subchapter / subchapterName, part / partName, subpart / subpartName, and popularName (e.g. “Truth in Lending Act”).
• Provenance: issueDate, crossReferencesCfr (parsed CFR references as a list of section strings, e.g. ['1.6011-4']), and govinfo granuleId / packageId.

​

Regulations, Federal Register, and agency guidance are now queryable

• REGULATION: state administrative regulations (176K+ rules across 12 states).
• FEDERAL_REGISTER: Federal Register agency rules, final and proposed (100K+ documents).
• AGENCY_GUIDANCE: agency guidance, including SSA rulings and IRS notices, revenue rulings, and procedures.
