D2g4 - Is work carried out inside a diplomatic mission to be regarded as having been carried out in the State to which the diplomatic mission is accredited?

Yes.

As the theory based on the fiction of extraterritoriality of diplomatic missions was abandoned a long time ago, it must be concluded that work carried out inside a diplomatic mission is to be regarded as having been carried out in the country to which that diplomatic mission is accredited.

Moreover, the courts of the country to which the diplomatic mission is accredited have territorial jurisdiction under Council Regulation (EC) No 44/2001 of 22 December 2000 on jurisdiction.
