It could be debated whether taking into account agents’ abilities and limitations properly belongs in the theory of legal interpretation. It might be, for example, that the proper place to take into account judges’ biases and limitations is the theory of adjudication. Let’s set aside this largely terminological question. Instead, we can distinguish between different degrees and kinds of idealization in the theory of legal interpretation. For example, one type of highly idealized theory asks how a legal interpreter without cognitive or time limitations best ascertains what the law is given the legally and morally permissible evidence (without taking into account values other than accuracy, except for the restriction to permissible evidence). A somewhat less idealized kind of theory asks how agents with specific abilities and limitations would, under real-world conditions, including limited time, do best at accurately identifying provisions’ contributions. Finally, we could ask how a legal interpreter should proceed taking into account not just accuracy, but also the kinds of values illustrated above, such as promoting good drafting.
