(dated) Arrogant behaviour; the act of venturing beyond due bounds of reverence or respect.Examples: "Note the preſumption of this Scythian ſlaue: I tel thee villaine, thoſe that lead my horſe Haue to their names tytles of dignitie, And dar’ſt thou bluntly cal me Baiazeth?"; "Thy son I killed for his presumption."; "[…]yet even then, I had the preſumption to Dedicate to your Lordſhip: A very unfiniſh'd Piece […]"countabledateduncountable

2. (law) An inference that a trier of fact is either permitted or required to draw under certain factual circumstances (as prescribed by statute or case law) unless the party against whom the inference is drawn is able to rebut it with admissible, competent evidence.Examples: "The state, in the exercise of its general power to prescribe rules of evidence, may provide that proof of a particular fact, or of several facts taken collectively, shall be prima facie evidence of another fact when there is some rational connection between the fact proved and the ultimate fact presumed. The legislative presumption is invalid when it is entirely arbitrary, or creates an invidious discrimination, or operates to deprive a party of a reasonable opportunity to present the pertinent facts in his defense."countableuncountable
