Blocking Executive Committee Nomination at AGM

Hello, We have an upcoming AGM. At which time we will be receiving nominations and signing people up for for the coming years EC. One vexacious resident  who has often been on the committee before, is not only unhelpful and does nothing in way shape or form; she goes out of her way to be difficult and to block or derail any attempts to get things done around the block.

Question: If they are “nominated” for the EC, is there anyway to have a “No” vote and therefore not have them on the EC? Thanks in advance, N
