- assume questions are asking about the substantive law;
- assume the facts as stated;
- don't require authors to complicate a question;
- assume the facts have been proved.
- international law is law
Unless a question clearly asks an evidential question (admissibility, hearsay, relevance, etc.), we take the facts in the question as a given, as if they were proved to the relevant standard of proof, and answer how the law would apply to them.
International law is law
If someone is asking about international law, they are starting from the premise that it exists and is meaningful as law — please engage with the question on that basis.
See the information at international and the linked Q&As in the expanded info. International law is a well-specified subfield of law in academia and in practice. Several Q&As on this site address the nature of international law:
- What gives rise to binding obligations at international law?
- What does it mean for international law to be binding? What is the nature of obligation at international law?
Regardless of enforceability, or the political aspect of international law, that does not remove its status as law. International law is perhaps not the archetypal example of law that we encounter in our day to day life, but the theory that all law must be an order of a sovereign backed by force has long been displaced, or at least challenged.
Of course it is open to an answer to observe that there are no treaties or customary international law that touch on a specific issue.
