  Candidate relevant factors include considerations—texts, practices, or attitudes—that concern the very question how candidate determinants bear on the law. Intentions about which intentions count, mentioned above (discussed in Dworkin 1985 and 1986) are such factors and canons or conventions of interpretation and procedural provisions are familiar further examples. These are not exempt from the question why and so how they should bear on the law. Something other than the factors must determine their relevance to the law, even when it is pre-theoretically plausible that they are indeed relevant. For example, an interpretive convention tends to have a significant effect on expectations about how the relevance of the other institutional factors that the convention concerns would be assessed in court, such that considerations of fairness favour conforming to the convention. If so, the convention is vindicated by considerations other than itself, and this holds for any similar factor (see Dworkin 1985, 1986 regarding legislative intentions; Greenberg 2004 regarding any aspect of the practice that concerns the relevance of other aspects).
