I want to know the answer to the following question:
Who, acting as registrar, informed North Korea that withdrawal was deliberately precluded by the original signatories of the International Covenant on Civil and Political Rights?
All the background I'm provided with is that "When North Korea declared its intention to do this the Secretary-General of the United Nations, acting as registrar, said that original signatories of the ICCPR had not overlooked the possibility of explicitly providing for withdrawal, but rather had deliberately intended not to provide for it.". Is that enough to answer the question?
Answer: yes
