inviolability

The case concerns an Iranian diplomat working at the embassy in Vienna (Austria), who was arrested in Germany and extradited to Belgium to face criminal charges for alleged involvement in terrorist activities. The Court acknowledges that diplomats enjoy inviolability when they are 'in transit' to or from the receiving State as part of  their diplomatic assignment pursuant to Article 40(1) of the Vienna Convention on Diplomatic Relations. However, this inviolability does not apply where a diplomat returns to the receiving State from a holiday in a third country.
