 If the precedent consists of more than one attribution, the theory additionally needs some way to resolve conflicts—cases where one attribution is to x, while another is to y. We could say that any conflict in the precedent results in either reference failure (Evans 1982: 389) or referential indeterminacy (Lewis 1984). But we can also imagine a more nuanced rule that prioritized certain properties in the event of a conflict (the way Evans prioritizes the applications of producers over those of consumers).
