Duplication
If the majority of your Proposal is covered by an existing Resolution, your Proposal is toast. We've got enough of these things already, we don't need to double up (i.e. the WA has already banned landmines, we don't need to do it again). As an aside, since the WA has already banned biological weapons, you don't need to include it in your Proposal to ban nuclear and chemical ones. (see: House of Cards)
