From where I sit, I think power should rest on the proportion of the work that creators' do on the property. For example, if both (or a party of) creators have agreed that they are equally responsible for the creation of a story, then anyone who wants to do business needs the approval of everyone involved to proceed.
If one creator is the principal (but can't be seen as the person who came up with an overwhelming part of the concept (i.e. 80% or more) ) then there word should have the most influence on what happens to the story and the I.P. it is legal purposes. At the same time, considerations of the co-creator(s) should come into account.
If one creator can be credited for the grand majority of the concept, then that creator's voice should be greater than his or her collaborators.
Of course, this isn't a perfect system, simply because once it gets to the legal dispute level, then it becomes that much harder to assign percentages to work, but I think it's a good place to start.
