Finding information about draft decisions or resolutions not adopted can be challenging.
Drafts may not be adopted for a variety of reasons, including:

Information for adopted resolutions of the General Assembly and Security Council may be found in the Voting Data in the UN Digital Library and for the Human Rights Council in the OHCHR Library Voting Data.
