10. Key Distinctions and Exam Points
10.1 Critical Distinctions

| Criminal vs Civil Immunity | Diplomats: absolute criminal, broad civil; Consuls: official acts only for both |
| Ratione Personae vs Ratione Materiae | Ratione personae = based on status (diplomats); Ratione materiae = based on acts (consuls, former diplomats for official acts) |
