✦ Synopsis

In the paradigm social choice problem, there is a fixed set of alternatives and a fixed set of voters. This essay considers variations of the electorate when some subset of voters has a special voice on some subset of alternatives. We formalized such a situation by means of the veto function. We focus on stable veto functions, exhibit a stable liberal social choice function and promotion mechanism, and investigate a notion of stability for groups whose membership itself is the social state.
