Lex Humana permits responsible use of generative artificial intelligence (GenAI), including LLMs, as an aid while preserving intellectual contribution, human accountability and confidentiality. The journal draws on CNPq Ordinance No. 2,664 of 6 March 2026, particularly Article 9(I)(c–f), whose regulatory scope is defined in Article 4. The editorial rules below apply to all participants in the journal.

1. Authors

Support for language editing, translation, information organisation, programming and other methodologically justified tasks is permitted with human verification. GenAI cannot be an author or replace the authors’ intellectual contribution. Generated content must not be presented as unaided human production, and tools must not fabricate data, sources, citations, results or evidence. Authors check original sources and remain fully responsible for the final text.

All GenAI use related to the research or manuscript must be disclosed at any stage, including language editing and translation. State the tool, version where available, purpose, stage of use and human verification performed. Methodological uses belong in Methods or an equivalent section; writing-only assistance may be disclosed in Acknowledgements or a statement before the references. Conventional non-generative spelling, grammar or formatting tools need not be declared. Synthetic content studied as a research object must be identified as such rather than presented as real observations.

Short model: “[Tool and version, where available] was used for [purpose and stage]. The authors reviewed and verified the content and take full responsibility for the final version.” Additional information may be requested when needed to assess the method.

2. Reviewers

Do not enter manuscripts, third-party projects or confidential documents into GenAI to prepare review reports. Critical assessment and recommendations must be the reviewer’s own and cannot be delegated to a tool. Language support for an already-written report is permitted only without exposing confidential content or changing the judgement; GenAI use must be disclosed to the editor with the tool and purpose. Suspected undisclosed use must be substantiated and referred to the editor.

3. Editors and editorial staff

GenAI may support administration, metadata, formatting, translation and communication under human oversight without improper disclosure. Manuscripts or third-party projects must not be entered into GenAI to generate scholarly assessments; acceptance, revision and rejection decisions cannot be delegated. Editorial GenAI use must be recorded with the tool and purpose and communicated to authors when it affects their text or correspondence. Content changes require the authors’ agreement.

4. Confidentiality and integrity

Everyone must check tool terms, retention, training and data protection before use. Personal data, confidential information and third-party material must not be supplied without the necessary grounds and permissions. AI detectors and similarity reports are not standalone proof of misconduct. Omissions and inappropriate use are examined under the ethics and integrity policy, with an opportunity to explain and proportionate measures.

5. References and further reading

CNPq — Ordinance No. 2,664/2026; Springer Nature — guidance for authors, reviewers and editors; Elsevier — generative AI policies for journals. These are complementary references; the journal’s express rules take precedence.

Authorship, contributions and submission (CRediT)

AI/LLM tools cannot receive authorship or CRediT roles assigned to human contributors. The contribution statement does not replace the AI-use declaration required by this policy.
