Power-law discrepancies force decisions while truth-logic ones do not.

Evidence

At the same time, this means that the relationship between power and law is more insecurely formulated than the relationship between truth and logic. Distributions of power can tend to endanger the legal order, and, because it is action-related, this tendency presses towards a decision, towards an approximation of the legal situation matching the power situation. A change of theories, on the other hand, hardly ever occurs on the basis of a discrepancy between truth and logic. In the context of knowledge one even can put up with truths (such as the truth, which goes back to Aristotle’s idea of the incapacity of truth where future contingencies are concerned) that contradict the binary schematism of logic, without these insights hampering the operative function of binary truth and logic. — Niklas Luhmann, Trust and Power, 665
