  In the above examples we can say that the right-token, as opposed to the right-type, comes into existence only when the condition for its instantiation is triggered. But legal systems sometimes say that that the right-token exists before one of the conditions for the exercise of the right exists. Essentially, it is the difference between saying “if p, X has a right to A” and “X has a right, if p, to A.” In the latter case the implication is that the right-token exists now, not just that it will exist. Why should we say this? One proposed answer is that legal systems, unlike morality, have devised sets of rules for transmission of rights even before the triggering condition for the exercise of the right has arrived.
