I want to know the answer to the following question:
In addition to the circumstances by which a state party joined a treaty, why might a treaty be invalidated?
All the background I'm provided with is that "Invalidation is separate from withdrawal, suspension, or termination (addressed above), which all involve an alteration in the consent of the parties of a previously valid treaty rather than the invalidation of that consent in the first place.". Is that enough to answer the question?
