Louisiana law by citation — Revised Statutes, Civil Code, Code of Civil Procedure, Code of Criminal Procedure, Code of Evidence, Children’s Code and the Louisiana Constitution — with each section’s enactment and amendment history parsed out, plus full-text topic search across those code bodies and a browse of every section in one Revised Statutes title. Keyless, sourced live from the Louisiana State Legislature.

Tools

• louisiana_statute(citation | doc_id) — full text of one section: "RS 14:20", "La. R.S. 9:2800.1", "14:20", "CC 2315", "La. C.C. art. 2315", "CCP 966", "C.Cr.P. art. 701", "CE 404", "CHC 603", "Const. Art. I, §5" / "CONST 1:5", or the legis.la.gov doc_id a search result carries. Returns heading, hierarchy (the chapter/title lines above the section), text, the trailing history line (“Added by Acts 1976, No. 655, §1. Amended by Acts 2014, No. 163, §1.”) parsed into amendments ({year, act, session}), and last_amended_year.
• louisiana_law_search(query, bodies?, limit?) — full-text search by topic/keyword (“vehicular homicide”, “security deposit lessor”, “comparative fault”), optionally narrowed to code bodies (RS, CC, CCP, CCRP, CE, CHC, CONST, CA, HRULE, SRULE, JRULE; default all). Relevance-ranked rows with citation, heading, last-modified date and doc_id, plus the source’s total.
• louisiana_title_contents(title, filter?, offset?, limit?) — every section of one Revised Statutes title with its heading and doc_id (Title 14 has 729, Title 32 has 870), optionally filtered by a word in the heading; repealed sections are flagged.

Data sources

• https://legis.la.gov/Legis/Law.aspx?d=78338 — one section page (that id is RS 14:20). Citation in #ctl00_PageBody_LabelName, text as <P> paragraphs in #ctl00_PageBody_LabelDocument, last paragraph = history.
• https://legis.la.gov/Legis/LawSearch.aspx — the “View a Specific Law” form and the text-search form.
• https://legis.la.gov/Legis/LawSearchList.aspx — where the search form cross-page-posts; renders the result rows.
• https://legis.la.gov/Legis/Laws_Toc.aspx?folder=75&level=Parent — the Revised Statutes table of contents (one LinkButton postback per title).

Shape of this source, because it is a WebForms site and not an API

Everything is reachable with plain HTTP — no cookie, no JavaScript, no CAPTCHA, no Lexis hop — but three of the four routes are form POSTs:

1. Doc ids are not in citation order. d=78337 is RS 14:2, d=78338 is RS 14:20, d=78339 is RS 14:201 (string-sorted). So a citation cannot be computed into a URL; the “View a Specific Law” form does the mapping. POST the form’s hidden __VIEWSTATE/__EVENTVALIDATION fields plus ddlLawBodies, tbFirstNumber, tbSecondNumber and btnViewLaw=View; the server answers 302 to Law.aspx?d=<id>. An unknown citation re-renders the form with HTTP 200 and no redirect — that is the not-found signal (there is no message).
2. Non-RS bodies need the dropdown’s own postback first. Selecting Civil Code etc. is a __doPostBack('...ddlLawBodies') that switches the form to a single “Article” box; posting the article number against the fresh RS-state form is silently ignored. The pack runs that switch once per body and caches the resulting hidden fields.
3. The viewstate is not session-bound. One GET of the form supplies fields that stay valid for repeated POSTs (verified: two different citations resolved off the same fields, no cookie ever set). The pack caches them per isolate for 30 minutes and refreshes once on a POST that comes back without a redirect, so a warm citation lookup is one POST + one GET.
4. Search posts to LawSearchList.aspx, not back to the form (the button’s WebForm_PostBackOptions names it). The per-body checkboxes are cbLaws$0..cbLaws$10 (0 CHC, 1 CC, 2 CCP, 3 CCRP, 4 CE, 5 CA, 6 CONST, 7 HRULE, 8 JRULE, 9 RS, 10 SRULE); cbLaws$11 “Select All” is client-side JavaScript only — the server ignores it, so “all bodies” means ticking all ten. A single-hit search 302s straight to the section page. The list renders the first 100 of N, relevance-sorted, and states N (“There are 347 sections of law in this list”).
5. A one-word query that matches too many sections is refused silently: "tax" against RS 302s back to the blank form, byte-identical to a fresh GET. The pack reports that as search_rejected with a hint to add a word. The engine ANDs every word; a or b, a not b and ""exact phrase"" (doubled quotes) are its own syntax.
6. Pages hard-wrap paragraphs with raw newlines. The history paragraph of RS 14:30 spans nine source lines. Split on <P> tags, never on newlines, or the history line fragments and only its first piece reads as history.
7. Form field names contain $. URLSearchParams encodes it as %24, which is what IIS expects; a body that leaves $ literal gets the form re-rendered with HTTP 200 and nothing else.

The four capabilities, and the one the source cannot do

laws_current_through on every response is the legislature’s own “updated through the …” line (e.g. “2025 First Extraordinary Session”), read from the search form.
