I want to know the answer to the following question:
The often unclear division between a self-executing treaty and a non-self-executing treaty can lead to a treaty being what if disagreements exist within a party?
All the background I'm provided with is that "The division between the two is often not clear and is often politicized in disagreements within a government over a treaty, since a non-self-executing treaty cannot be acted on without the proper change in domestic law.". Is that enough to answer the question?
Answer: yes
