18 As Hansen JA observed in KRI v R,[7] the test for the admissibility of tendency evidence is one of fact and degree to be assessed in light of the facts and circumstances of the particular case. And in the facts and circumstances of this case, I am not persuaded there is room for doubt about it. As the judge held, it is a remarkable thing for a man to commit sexual acts against his female lineal descendants. It is still more remarkable when, in each case, the nature of the acts is similar if not identical, even if they are commonplace sexual acts. It is even more remarkable that in each case the acts were committed in the home while the victim was in the applicant's care, while other adults were close by and the risk of detection was significant. It follows that, if accepted, the evidence of the applicant's prior offending against his daughters would demonstrate that he had a tendency to be sexually attracted to his young female descendants and to act upon that attraction in similar ways at different times, when the victims were in his home under his care and thus vulnerable to his advances. As such, as the judge held, it would be capable of rationally affecting the assessment of the probability of the applicant having had a sexual interest in his granddaughter and giving effect to it by committing the offence alleged.
