  It is important to consider how interpretation, as characterised in subsection 2.2 above, fits into the discussion of the ambit of the term legal reasoning in the opening section of this entry. The key to this issue lies in interpretation's dualistic nature, i.e. that it has both a backward-looking conserving aspect and a forward-looking creative one. This dualism would seem to indicate that in interpreting the law, judges both seek to capture and be faithful to the content of the law as it currently exists, and to supplement, modify, or bring out something new in the law, in the course of reasoning from the content of the law to a decision in a particular case. In turn, this would seem to indicate that interpretation, because of its dualistic nature, has a role to play in both legal reasoning in sense (a), i.e. reasoning to establish the existing content of the law on a given issue, and legal reasoning in sense (b), namely reasoning from the existing content of the law to the decision which a court should reach in a case involving that issue which comes before it.
