I want to know the answer to the following question:
A manifest violation is required to invalidate a party's consent to a treaty due to a reluctance internationally to inquire into what aspects of other states?
All the background I'm provided with is that "States are reluctant to inquire into the internal affairs and processes of other states, and so a "manifest violation" is required such that it would be "objectively evident to any State dealing with the matter".". Is that enough to answer the question?
Answer: yes
