states are based revolving around principles of equality and non discrimination and therefore there are not many obstacles in this aspect. However the problems become particularly acute in those cases which may require the application of rules of law that are foreign to the particular country’s courts. In cases having elements that connect them with other jurisdictions, one of the questions that arise is whether foreign rules of law should be reflected in the decision of the court, and if so, to what extent. In essence this is a question of choice of law.
The recognition of the Renvoi theory implies that the rules of the conflict of laws are to be understood as incorporating not only the ordinary or internal law of the foreign state or country, but its rules of the conflict of laws as well. According to this theory “the law of a country” means the whole of its law.
