"Introduction We digress when, in intending to make a point, we either temporarily or permanently deviate from it. Digressions can be deliberate or unconscious. They can be to good or bad - or a mixture of good and bad - or to no effect. Distinguishing the digressive from the non-digressive is not always straightforward: comments offered as asides can strike at the very heart of a matter, just as narrative which a reader thinks peripheral might be the author's fil conducteur. Common-law judges often digress in the course of making legal decisions. The standard characterization of these digressions is that they are observations which are not integral to a decision that has been reached - that they could be taken out of a judgment without that judgment being undermined. The full legal Latin term for these observations is obiter dicta"--.
