Replacement

A replacement proposal or replacement resolution is a United Nations proposal or resolution that was written to improve upon a pre-existing resolution. Often replacements will be drafted along side a repeal, but, in most cases, the only time it is legal for a replacement to be submitted to the proposal queue is after the successful repeal of a resolution. The exception is when the "replacement" covers a slightly different area than the original and they can legally co-exist on the books, such as in the case of Banning the Use of Landmines and UN Demining Survey.

Replacements exist for two reasons. First, sometimes loopholes in a resolution are exposed during the UN floor debate or following the debate, and UN members work to create a new document that will close those loopholes. Second, some replacements are also blocker resolutions or less restrictive. These replacements are purposefully designed to give nations more leeway.

Replacements are not always planned. Sometimes a resolution is repealed and competing groups of nations attempt to replace the repealed resolution with either a new (though often better written) version of the original resolution or a blocker resolution. The first example of a replacement being drafted after an unplanned repeal was when the Sex Industry Worker Act.
