57 legislative offices, multiple caucuses, and simultaneous agendas.
Many files, limited technical time.
Advisory teams must turn long documents into usable guidance for committees, caucuses, or plenary sessions without losing legal precision.
Legislative intelligence for Costa Rica
Audit, draft, and anticipate laws, with verifiable rigor.
Sirius-Lex supports the full life of a bill: audit a file article by article, draft a new one through a staged process with human checkpoints, and anticipate its path through the Assembly. Always with sources, traceability, and human review.
On-demand consulting service, with findings and documents traceable to official sources. For legislative advisory teams, caucuses, law firms, and regulatory teams.
The bottleneck is not political. It is technical.
Legislative decisions are made under tight timelines, long files, and public scrutiny. Risk appears when the technical team does not have enough time to verify every citation, every article, and every effect on the current legal framework.
The Rules of Procedure of the Legislative Assembly require bills to be submitted in open digital format.
The file is digital. The review is still fragmented.
Having a digital text does not solve citation review, constitutional analysis, affected laws, or institutional impact.
In File 25.616, Sirius-Lex detected a reference to a Criminal Code article the bill itself never creates.
A citation error can change the analysis.
A misattributed reference weakens the bill's legal foundation and exposes the office to late corrections.
Deliverables
What the client receives
Sirius-Lex works on three fronts: auditing existing bills, decrees, and other regulatory texts, drafting new bills with method, and anticipating their political path. Each front is delivered as a consulting product: prioritized findings, verifiable evidence, and recommendations so the technical team can decide what to correct, propose, or defend.
Audit Review what already exists
01
Constitutional and legal audit
Article-by-article review of the normative text —bill, decree, or regulation— to identify constitutional risks, tensions with legal principles, and issues of normative coherence.
02
Legal citation verification
Review of each legal reference against current Costa Rican legislation, flagging correct, incomplete, ambiguous, or misattributed citations.
03
Impact and conflict map
Identification of laws, institutional powers, and secondary effects that may be affected, with cross-analysis of related files to detect duplication, contradictions, or gaps.
04
Traceable executive report
Exportable document with summary, findings, risk status, sources, and recommended points for human review, plus a one-page technical brief for the caucus.

Verified real cases
Real files, verifiable findings
Sirius-Lex analyzes bills in progress as preventive legislative quality control. Each analysis reviews the text against current Costa Rican legislation, verifies legal citations against their sources, and classifies findings by risk level. These are recent examples.
Firm hand against criminal recidivism
File 25.616 · In committee · Security and Narcotics
Sirius-Lex audited the bill toughening the criminal treatment of recidivism: 7 articles reviewed and 37 legal references checked against official sources. The analysis identified eight critical findings in the punitive and procedural core of the reform, twelve citations contradicting their own sources, and twenty impacts on current law.
Analysis dated July 25, 2026, on the base text
Alternative measures excluded across the board
The new Article 241 bis closes with a one-line clause: "the precautionary measures provided for in section 244 shall not apply". The current Article 244 is the rule that requires the judge to impose the least burdensome measure whenever it suffices. Excluding it wholesale removes the principle of necessity from every case the new article covers.
An article that promises to expunge records and does the opposite
The new Article 71 quater is titled "Cancellation of criminal records", yet its text regulates no cancellation at all: it orders records to be preserved and only bars disclosure to third parties fifteen years after the sentence is extinguished. Other articles of the bill refer to a cancellation "under Article 71 quater" that does not exist.
Reference to an article the bill never creates
The new Article 241 bis of the Criminal Procedure Code refers to qualified recidivism "under Article 39 ter" of the Criminal Code. That provision does not exist in the current Code, and the bill itself creates it as Article 39 bis, not 39 ter. The error sits in the grounds for a pretrial detention cause.

Metallic mining in Cutris, San Carlos
File 24.717 · Committee-approved · Environment Committee
Sirius-Lex audited the bill authorizing metallic mining in the Cutris district: 25 articles reviewed against current legislation and 23 legal references checked against their sources. The analysis identified four critical findings verified against the current text, including a nationwide reform embedded in a district-level regime, plus twenty-three legal-precision observations.
Analysis dated July 24, 2026, on the updated text
Cyanide drops off the list: a reform with nationwide scope
Article 20 amends subsection k) of Article 103 of the Mining Code, replacing the current "cyanide and mercury leaching" with "mercury amalgamation". Cyanide leaching thereby ceases to appear among the factors the law classifies as environmentally harmful, and Article 103 applies nationwide, not only in Cutris.
Reference to a provision that does not yet exist
Article 12 refers to the "minimum base royalty under Article 55" of the Mining Code, and Article 13 to its "section III". The current Article 55 contains neither that section nor that royalty: the bill itself introduces them through its Article 21. The reference treats as current law a provision that would only exist if this same bill passes.
Concessions shielded against repeal of the law itself
Article 23 provides that concessions shall keep their validity and conditions "even in the event of a total or partial repeal of this law". It attempts to place the regime beyond the exclusive power of the Legislative Assembly to enact, amend, and repeal laws (Article 121 of the Constitution).

Harmonization of the National Electricity System
File 23.414 · Passed first debate
Sirius-Lex audited the bill reorganizing the national electricity market: 79 articles reviewed and 18 legal references checked against official sources, 15 of them confirmed. The analysis identified two critical findings, one of constitutional form and one of internal cross-reference, plus eleven legal-precision observations.
Analysis dated July 24, 2026, on the updated text
A three-law exemption pointing to a list that does not exist
Article 55 exempts "the public companies listed in Article 38" from the public employment, public finance, and public procurement regimes. That article contains no list: the actual list appears in Article 35. The scope of an exemption of that magnitude is left undefined by the text itself.
An autonomous institution requiring a supermajority
Article 17 creates ECOSEN as an autonomous institution, a figure the Constitution reserves for a two-thirds vote of the Assembly (Article 189). Since the rest of the bill depends organically on ECOSEN, a formal defect on that point would compromise the approval procedure of the entire law.
Two repeal criteria that do not match
Article 63 repeals Law 7200 eighteen months after entry into force or once the market becomes operational; Transitory XVI keeps it in force under different conditions with no fixed deadline. Two inconsistent rules within the same text leave it unclear when the prior law ceases to apply.

Service
How the service works
Sirius-Lex is engaged per analysis or consulting assignment, and starts through one of two entry points: a file that needs auditing, or a bill that needs drafting from scratch.
Two entry points
You bring a file
We audit it article by article: verified citations, constitutional risks, and normative conflicts, with a traceable report.
You want to create a new one
We draft it with method: a staged process with checkpoints where you decide, from the initial framing to the final articles.
01
Define the starting point
The client identifies the file to review or the framing of the bill to draft, together with the main technical question and intended use.
02
Do the work
The file is audited or the bill is drafted following the corresponding method: citations, risks, and impact for audits; stages and checkpoints for drafting.
03
Deliver and discuss results
The report or the drafted bill is delivered and critical points are reviewed with the client's team to prioritize corrections, questions, or decisions.
Timeline
An initial review can be organized within 24-48 hours, depending on scope, text availability, and file complexity. Extensive or comparative analyses are scheduled by scope.
What the report includes
Executive summary, risk status, verified citations, article-level observations, regulatory impact map, detected conflicts, review recommendations, and limitations note.
Differentiation
Not a general legal AI
Sirius-Lex does not compete to answer any legal question. Its focus is the full life of a legislative file: auditing what exists, drafting what is missing, and anticipating its political path, always turned into verifiable findings.
| Comparison | What it solves | Typical limit | How Sirius-Lex is different |
|---|---|---|---|
| SOFIA / Tirant | Research, conversation, drafting, and general legal analysis. | Not focused on the parliamentary workflow of a specific file. | Sirius-Lex organizes the analysis around the file, its articles, citations, risks, and legislative impacts. |

The difference is not replacing legal judgment. It is giving the technical team a more structured, traceable, and timely review before the file moves forward. None of these alternatives drafts new bills with human checkpoints, or computes an advancement-probability score calibrated against the Costa Rican legislative record.
Audience
Built for teams that prepare legislative guidance
Sirius-Lex is designed for teams that need to read, draft, compare, explain, or challenge legislative files with speed and rigor.
01
Legislative advisors and chiefs of staff
Pain
They must summarize long files, draft or review their own proposals, and avoid technical errors before meetings, committee sessions, or plenary debate.
02
Political caucuses and technical coordinators
Pain
They need consistent guidance across multiple files and a method to originate their own bills, with a common view of risks, citations, and decision points.
03
Law firms and regulatory teams
Pain
They must explain to clients or internal teams how a bill may affect obligations, institutional powers, or sector-specific risks, or draft reform proposals with the same rigor.
04
Consulting firms and cooperation organizations
Pain
They require traceable legislative diagnostics and, often, method-drafted regulatory proposals for modernization, digital government, responsible AI, or institutional strengthening projects.
Use cases
When to use Sirius-Lex
Use Sirius-Lex when your team needs to turn a legislative file into verifiable technical guidance before a decision.
- Review a bill before its committee presentation.
- Prepare technical guidance with verifiable findings and identified sources.
- Detect constitutional risks, erroneous citations, or normative conflicts.
- Compare related legislative files to identify duplication or contradictions.
- Validate legal citations before submitting formal observations.
Sources and traceability
Verifiable sources. Human review. Clear limits.
Sirius-Lex works with current Costa Rican legislation and structures each finding so it can be reviewed against an identifiable source. The result is a technical basis for decision-making, not an official legal opinion.
Traceability by finding
Each relevant observation is linked to a rule, article, source, and explanation of why it matters for the file.
Quality gate
The analysis applies exit criteria: zero invented citations, complete traceability, and human review before the report is used as an external input.
Auditable base
Sirius-Lex relies on an auditable technology base. SiriusOS provides transparency for the engine; legislative specialization and consulting judgment are delivered as a professional service.
Sirius-Lex findings are not an official legal opinion and do not replace human legal review.
