Proposal: Creation of a new Repeal-and-Replace category for World Assembly resolutions.
Rationale: The current process of using separate proposals to repeal and replace a resolution is inefficient and error-prone. It takes nearly a week of voting, and can break down between the two steps.
Details:
A repeal-and-replace resolution would combine both an explanation of why the previous resolution is insufficient and a replacement for the resolution. This would be a single resolution, and therefore would only require one vote. If it passes, it would cause the previous resolution to be considered repealed, and would have an effect of half that of a new proposal (a repeal removes half the effect of the original, and a replacement has full effect, which balances to one-half effect) of the same category and strength of the original.
Possible criticisms:
"It can't be done; amendments aren't possible!"
Amending past resolutions is not possible, because interpreting the effect of the amendment is too difficult. However, this does not have that problem. It merely combines the repeal of a resolution with its replacement. The effect of this is well-understood, as it has long been done with separate proposals.
"A combined repeal-and-replace is too long to fit in the character limit!"
"What if the replacement needs a different category and strength?"
In some cases, the traditional two-proposal route would need to be taken. In many cases, however, a combined proposal works perfectly well. That it could not always be used is no reason to prevent its use where possible.
"But what about those who don't want a replacement?"
A simple repeal would still be an option. The only loss would be claiming that a replacement would be written and submitted to get support for the repeal and refusing to then follow through.
