SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, beautifulsoup4, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Manually searching the official ICJ/PCIJ website for case law, jurisdictional rules, and state optional-clause declarations is time-consuming, and pre-trained knowledge often lacks up-to-date declaration text that is only authoritative on icj-cij.org.

Core Features & Use Cases

  • ICJ/PCIJ Case Law Lookup: Retrieve contentious and advisory cases, including PCIJ Series A/B/A/B judgments and advisory opinions from 1922-1940, with direct links to official PDFs.
  • Jurisdictional Analysis: Access the Court's official jurisdiction pages, including state eligibility to appear, treaty bases for jurisdiction, and UN organs authorized to request advisory opinions.
  • Article 36(2) Declaration Comparison: Retrieve and compare verbatim optional-clause declarations from any state to assess compulsory jurisdiction for cross-border disputes, with built-in guidance for applying reciprocity rules.
  • Use Case: A legal researcher can quickly verify if Norway and Finland have overlapping compulsory jurisdiction for a territorial dispute by comparing their Article 36(2) declarations directly via the skill.

Quick Start

Use the icj skill to retrieve the full text of Norway's Article 36(2) optional-clause declaration and compare it side-by-side with Finland's to assess whether the ICJ has compulsory jurisdiction for a territorial dispute between the two states.
