23 The form of the presentment in this case produced a difficult sentencing task for the primary judge. A 19-count presentment of itself can create difficulties which are compounded when most of those counts are representative counts and are based on incidents selected from a long history of offending. It might be thought that in this case properly particularised counts alleging the offence created by s 47A of the Crimes Act 1958 in respect of each of the victims and an appropriate pornography count might have been a much better course for the prosecutor to have taken. The presentment would have been considerably shorter and the real gravamen of Davy's offending would have been exposed for what it was - persistent sexual abuse. The s 47A offence, now referred to as 'persistent sexual abuse of a child under the age of 16' and formerly called 'maintaining a sexual relationship with a child under the age of 16', would seem to have been well suited to the principal offending in this case. This might have been particularly so as, at all relevant times, Davy had indicated a preparedness to plead guilty. The full extent of Davy's criminality could have been exposed by laying such counts with particulars alleging the most significant of the facts that formed the substance of the presentment with which the sentencing judge had to grapple. The maximum sentence for that offence is 25 years' imprisonment, thus providing the judge with ample scope for appropriate punishment with properly structured sentences. It is not without significance that the investigating police may have had this offence in mind when they interrogated Davy. Further, the use of representative counts in this case, when there were already as many individual discrete offences as were charged, was an unwarranted complication. The context and circumstances of each count were amply demonstrated by the existence of so many other counts, to all of which Davy pleaded guilty.
