Here is mentioned that:
The United Nations Partition Plan for Palestine was a proposal by the United Nations, which recommended a partition of Mandatory Palestine at the end of the British Mandate. On 29 November 1947, the UN General Assembly adopted the Plan as Resolution 181 (II).
The plan was adopted in the General Assembly and from legal point of view, General Assembly resolutions are non-binding.
And this source says:
Articles 10 and 14 of the UN Charter refer to General Assembly resolutions as “recommendations”, and the International Court of Justice has stressed the recommendatory nature of General Assembly resolutions repeatedly.
- What is the legal status of the State of Israel while the resolution was adopted in the General Assembly?
