# UK Legal Research with Lex API

This skill requires the **Lex MCP server** to be installed and enabled. The skill provides guidance on using the Lex tools effectively for UK legal research.

## Prerequisites: Lex MCP Server

Check if Lex tools are available (e.g. `search_legislation`, `search_caselaw`). If not installed, refer the user to https://github.com/i-dot-ai/lex for setup instructions.

## When to Use This Skill
- Researching UK legislation (Acts, Statutory Instruments)
- Finding court judgments and legal precedents
- Searching for specific legal provisions or sections
- Analysing how legislation has been amended over time
- Grounding AI responses in authoritative UK legal sources

## Available Tools

The Lex MCP server provides these tools:

### Legislation Search
- **search_legislation** - Semantic search across UK Acts and Statutory Instruments
- **search_legislation_sections** - Search within specific provisions and sections
- **get_legislation_amendments** - Find amendments to legislation

### Case Law Search
- **search_caselaw** - Semantic search across court judgments
- **search_caselaw_paragraphs** - Search within case paragraphs
- **find_caselaw_references** - Find cases referencing specific legislation

## Search Best Practices

1. **Be specific with queries** - "employment tribunal unfair dismissal" works better than "employment law"
2. **Use filters** - Filter by year, court, or legislation type when possible
3. **Combine searches** - Search legislation first, then find related case law
4. **Check amendments** - Legislation may have been amended since enactment

## Data Coverage

- **Legislation**: 1267-present (complete from 1963)
- **Case Law**: 2001-present
- **Sources**: The National Archives, Find Case Law

## Important Notes

- This is an experimental service for research purposes
- PDF-sourced legislation (pre-1963) uses LLM extraction - verify at source for critical accuracy
- Rate limited to 60 requests/minute
