Concept
The principle of territoriality generally limits the power of a country of judicial enforcement of actions to be taken within its territory.
Consequently, when a court decision is to be enforced out of property in another country, or requires some act to be done in that other country, the court decision must be brought to the court of that other country for implementation. This allows the court of the enforcing country to examine the decision to determine whether it should be recognized and enforced.
