Who is this for

This workflow is designed for legal professionals, policy analysts, and compliance teams who need to:

  • Research case law, legislation, and regulatory developments on specific topics
  • Build comprehensive legal intelligence reports from authoritative sources
  • Track enforcement trends and regulatory patterns
  • Support litigation strategy with thorough background research

It's ideal for animal law attorneys, advocacy organizations tracking animal welfare legislation, policy teams monitoring ag-gag laws and farm animal protection bills, and researchers building legal cases against animal cruelty.

What it does

This specialized legal research agent conducts comprehensive US legal and regulatory research:

  1. Discovery phase: Casts a wide net across legal databases
    • CourtListener for federal and state court opinions and dockets
    • LegiScan for legislation across all 50 states
    • DocumentCloud for government enforcement documents
    • Serper for legal analysis, news, and academic papers
  2. Prioritization phase: AI evaluates all discovered items and selects the most relevant (3-10 items) with scoring rationale
  3. Retrieval phase: Fetches complete text of prioritized court opinions, bill text, and documents
  4. Analysis phase: Synthesizes patterns, contradictions, and strategic insights
  5. Verification phase: Validates factual claims against source documents with hallucination detection

The verification phase uses a specialized legal-focused prompt that distinguishes between legitimate legal strategy (which should never be flagged) and actual factual errors like wrong case citations or non-existent statutes.

How to set up

  1. Import the workflow into your n8n instance
  2. Configure the required API credentials:
    • CourtListener API for case law searches
    • LegiScan API for legislation searches
    • Serper API for web searches
    • Jina AI API for article extraction
    • OpenRouter API for AI analysis
  3. Test with a well-documented legal topic to verify integrations
  4. Activate the workflow

Example usage

{
  "prompt": "Research the current legal challenges to California Proposition 12 (farm animal confinement standards), including constitutional commerce clause arguments and enforcement status"
}

Requirements

  • CourtListener API key (free tier available)
  • LegiScan API key
  • Serper API key

How to customize

  • Add jurisdiction filters: Limit searches to specific federal circuits or states with active animal welfare legislation
  • Adjust time ranges: Focus on recent developments or historical case law in animal protection
  • Extend source types: Add USDA enforcement records, state animal cruelty databases, or international animal law sources
  • Modify verification strictness: Adjust the hallucination detection threshold for legal accuracy
  • Create specialized variants: Fork for specific areas (ag-gag laws, farmed animal welfare, animal testing regulations, wildlife protection)
  • Add citation formatting: Post-process reports to use proper legal citation formats (Bluebook, etc.)
  • Integrate with legal tools: Connect to Clio, case management systems, or your organization's legal database
