Describe the question in your own words
Explain the case as you would to a colleague. Natural-language search lets you describe what you need without memorising search syntax.
How it works
Research Portuguese case law. Keep the source in view.
IAJUS.pt helps you find court decisions by meaning and by their full text, with links to the pages where they were published.
This page introduces the product in English. Legal documents, research interfaces and integration guides remain in Portuguese.
Find decisions that address the same issue
Semantic search looks for related ideas, including decisions that use different wording. Full-text search helps when you already know the expression or case number you are looking for.
Open and check the source
Results link to the original publication page when available. A page is identified as an official source only when the server has verified it. Read the original decision before relying on or citing it.
Use the AI assistant you already work with
Connect through a plugin or an MCP connector. The Portuguese integration guides explain the available platforms and their setup requirements.
Four ways to find a decision
By meaning
Describe the issue in your own words to find decisions that discuss related ideas.
By text
Look for an exact expression or case number in the full text of a decision.
Hybrid search
Combine semantic and full-text search, with the results ranked together.
By pattern
Use a regular expression to find sets of case numbers, legal references or citation patterns.
What the Portuguese service covers
The service currently searches Portuguese case law. Legislation has been collected but is not yet searchable through this service. The Portuguese collection does not include legal scholarship.
The data includes verified official sources and historical mirrors. Coverage grows court by court; the collection does not claim to contain everything published on official portals.

Identifiers and professional judgement
References constructed by IAJUS are internal identifiers, not official Portuguese ECLI identifiers. For a legal citation, use the case number and the original publication link.
IAJUS supports legal research. It does not provide legal advice. Checking the sources, exercising professional judgement and taking responsibility for their use remain the work of the legal professional.
