I would recommend Diplomatic Law: Privileges and Immunities to anyone looking for a deeper understanding of privileges and immunities. It's not just a course for practitioners but one which could benefit anyone from government employees, police officers, lawyers, employees of international organizations and even students. The lecturer was extremely knowlegeable and the administrator was extremely helpful and attentive. I had the opportunity to interact with other practitioners in the field from around the world and even persons not working in the field of diplomacy. It was a tremendous experience, that I benefited from greatly!
