SB117 replaces the state's statutory congressional map by enacting R.S. 18:1276 and repealing the prior R.S. 18:1276.1. The new statute describes Louisiana's six U.S. House districts as enumerated lists of parish precincts.
The bill anchors those lists to a specific GIS product — the Legislature's "2026 Precinct Shapefiles (1-27-2026)" — and includes transitional rules for offices and elections so the new descriptions can be used for candidate qualifying in 2028 while preserving certain incumbents' terms through January 3, 2029. That combination of a text-based precinct list plus an explicit shapefile reference is the operational core of the measure and the reason it matters to election officials, candidates, and local authorities.
At a Glance
What It Does
SB117 enacts a new statute that defines six congressional districts by listing every included parish precinct and ties those precinct references to a named Legislature-hosted precinct shapefile. It also repeals the prior statutory description and contains rules about precinct subdivisions and territorial continuity.
Who It Affects
State election administrators, parish governing authorities that maintain precincts, secretaries of state and registrars who run congressional candidate qualifying and elections, candidates for U.S. House, and local positions whose districts are defined by congressional boundaries.
Why It Matters
By placing precinct lists in statute and pointing to a specific shapefile, the bill converts a GIS product into the de facto legal boundary reference; that reduces ambiguity for mapping but shifts implementation work to clerks, registrars, and GIS staff and creates a narrow window for 2028 election administration to adopt the new descriptions.

What This Bill Actually Does
SB117 rewrites Louisiana’s congressional map into statute by enacting R.S. 18:1276. Instead of relying only on narrative descriptions or external maps, the statute enumerates — precinct by precinct — which portions of parishes belong to each of the six congressional districts.
Those precinct lists are the operative legal descriptions used to identify district membership.
The bill explicitly ties those precinct references to a named set of GIS files: the Legislature’s "2026 Precinct Shapefiles (1-27-2026)." Those shapefiles are described in the bill as being based on the 2020 Census TIGER/Line VTDs, modified through the Legislature’s data verification program to include precinct changes submitted by parish governing authorities through January 27, 2026. When a parish subdivides a precinct on either a geographic or nongeographic basis, the statute treats the parent precinct enumeration as including all subdivisions regardless of their later designations.SB117 also addresses continuity and transition.
It repeals the prior statutory description (R.S. 18:1276.1), protects the current terms of any office that was filled based on the previous districting, and specifies that any office filled after January 3, 2029, that is apportioned by congressional district must use the new district descriptions. For election administration, the bill makes the new district descriptions available for candidate qualifying and the conduct of the regular 2028 congressional elections as soon as the governor signs the bill (or it becomes law without signature), while reserving full legal effect for other purposes at noon on January 3, 2029.Operationally, the statute also contains a territorial-continuity rule: the district boundaries created by the precinct enumerations remain in force until changed by law even if parish governing authorities later alter precinct lines.
The combination of textual precinct lists, the legislatively referenced shapefile, and a phased effective date is the bill’s practical architecture for moving from a 2020-census-based map to a revised map tied to 2026-validated precinct data.
The Five Things You Need to Know
The bill makes the new district descriptions available for candidate qualifying and the regular 2028 congressional elections immediately upon the governor’s signature (or lapse of time), while reserving complete legal effect for other purposes at noon on January 3, 2029.
SB117 requires that the precinct enumerations in the statute correspond to the Legislature’s "2026 Precinct Shapefiles (1-27-2026)", which are based on 2020 TIGER/Line VTDs as modified and validated through the Legislature’s data verification program up to Jan. 27, 2026.
When a precinct cited in the statute has been subdivided by a parish on either a geographic or nongeographic basis, the statutory precinct enumeration is read to include all subdivisions, however they are later designated by the parish.
The act repeals the previous statutory congressional description (R.S. 18:1276.1) and replaces it with R.S. 18:1276, a full precinct-by-precinct listing of the six districts.
The bill contains a targeted transition safeguard: it does not shorten the term of any person holding an office on the effective date if that office’s appointment or election is based on the old congressional districts; however, any office filled after Jan. 3, 2029, must reflect the new districts.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Statutory precinct-by-precinct district descriptions
This is the operative mapping provision: the statute lists — parish precinct by precinct — the geographic composition of each of Louisiana’s six congressional districts. From a practical standpoint, that transforms local precinct identifiers into legal boundary descriptors. For election officials this means membership in a congressional district will be determined by matching a voter’s precinct to the statutory enumeration (or the referenced shapefile). The statute does not attempt a narrative boundary description; it is a roll call of precinct identifiers.
Repeal of prior statutory description (R.S. 18:1276.1)
This section removes the earlier statutory map and replaces it with the new R.S. 18:1276 precinct lists. The repeal is timed in the bill: the old provision remains in force until the new districting becomes fully effective as provided later in the act. That staged replacement preserves a legal map during the transition period.
Reference to the Legislature’s 2026 precinct shapefiles and subdivision rule
Section 3 ties the statute’s precinct identifiers to the published file named "2026 Precinct Shapefiles (1-27-2026)" hosted by the Legislature and confirms those files are based on 2020 TIGER/Line VTDs as adjusted through a verification process. It also specifies that statutory precinct designations include any geographic or nongeographic subdivisions created by parish governing authorities, removing a common point of mapping ambiguity where later parish actions change precinct labels or split precincts.
Transitional protections for office terms
Section 4 prevents the act from shortening the term of any officeholder whose office is apportioned according to the prior congressional districts. It further provides that positions appointed or elected after January 3, 2029, that are based on congressional districts must use the new district definitions. Practically, this staggers administrative and representational change so incumbents and offices with mid-term cycles are not displaced midterm.
Phased effective dates and election-use rule
This section contains the bill’s timing rules: the district descriptions in Section 1 become effective for the narrow purpose of candidate qualifying and conducting the regular 2028 congressional elections upon the governor’s signature (or lapse). For 'all other purposes' the Section 1 descriptions — and the repeal of the prior statute — become effective at noon on January 3, 2029. The bill also makes Sections 3 and 4 effective upon signature (or lapse), so parish and election officials have the legal reference and subdivision rule in hand immediately.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State and parish election administrators — gain a single, legislatively referenced legal source (precinct lists plus a named shapefile) for drawing and certifying district membership, reducing ambiguity when mapping voter rolls and ballots.
- Candidates and parties preparing for 2028 qualifying — receive clarity early because the bill makes the new statutory descriptions available for qualifying and election administration once the governor acts.
- Voters in precincts with clear statutory assignment — benefit from legal certainty about district membership when precinct identifiers are unambiguous and tied to a published shapefile.
- Local registrars and GIS teams — benefit from the explicit GIS file reference because it supplies an authoritative shapefile to use for mapping, audits, and ballot-layout work.
- Offices and incumbents with midterm appointments — receive protection from immediate displacement because the bill preserves their terms until the January 3, 2029, transition date.
Who Bears the Cost
- Parish governing authorities and clerks — must reconcile their precinct management and labeling with the statute and the Legislature’s shapefile, potentially updating records, precinct maps, and voter lookup tools.
- Secretaries of state and registrars — face immediate operational work to adopt the new statutory descriptions and the Legislature’s shapefile into voter-registration systems, precinct-to-district lookups, and candidate-qualifying processes before 2028 qualifying begins.
- Candidates and campaigns — must absorb near-term costs to verify district lines, update canvassing plans and outreach, and potentially adjust filing strategies based on the new precinct-based descriptions.
- GIS and IT teams for election offices — bear the technical burden of ingesting the named shapefile, resolving any mismatches with parish data, and implementing rule logic for precinct subdivisions.
- Potential litigants and courts — although not a fiscal actor in the bill, litigation costs may arise if parties challenge equal-population, voting-rights, or procedural aspects of the new descriptions, imposing downstream administrative expenses.
Key Issues
The Core Tension
The bill prioritizes legal certainty and administrative utility by codifying precinct lists and pointing to a named shapefile, but that same choice forces a dependence on multiple data sources (parish precinct records, the Legislature’s verification edits, and the GIS file). The central dilemma is between producing a single, authoritative legal map quickly for upcoming elections and accepting the implementation burden and potential for data mismatches that come with fixing boundaries to a specific, legislatively referenced dataset.
The bill’s approach — embedding exhaustive precinct lists in statute while pointing to a named shapefile — trades one form of ambiguity for another. On the one hand, a published shapefile plus statutory precinct identifiers give election officials an authoritative source; on the other hand, the statute depends on accurate parity between parish precinct identifiers, the Legislature’s verified VTD modifications, and the GIS product.
Any discrepancy among those sources will require technical reconciliation, and the statute’s instruction to treat parent precinct enumerations as including later subdivisions can create interpretive edge cases when parishes subdivide along nongeographic or differently named lines.
The phased effective date reduces immediate disruption by allowing 2028 qualifying to use the new descriptions while delaying full legal effect until 2029, but it compresses the timeline for election administrators and candidates to operationalize the map for 2028 filing and ballot preparation. That compressed window increases the risk of administrative errors or last-minute disputes.
Finally, while the statute preserves incumbents' terms through January 3, 2029, it does not resolve how mid-cycle local or administrative boundary changes that affect precinct labels will be treated in practice when developing voter-facing lookup tools or when courts require precise, parcel-level maps for litigation.
