Answers to these kind of questions are given some content by research which has been carried out on who is prosecuted for the crime of HIV transmission in Canada and for what kind of sexual encounters. There is a lot of fascinating material in the report, but I want to pull out two key findings. These are first that in a high percentage of the prosecutions (40%) no actual HIV transmission had taken place - that is to say that the person was being prosecuted for an aggravated sexual offence where what was at issue was the risk of serous bodily harm. Second, the majority of those prosecuted were heterosexual men (around 70%) - which is to say those who were prosecuted on the basis of a heterosexual encounter - and in the period since 2004 the majority of these were black. In seeking to explain this last finding, the authors of the report make two observations. The first is that this might reflect differences in understandings of and respones to HIV risk between the gay and heterosexual communities. And second, they suggest that heterosexual women, and especially white heterosexual women, who are the complainants in many of these cases better fit police and prosecution conceptions of victims - and so the cases are more likely to be taken up.
So, if we go back to the discussion of the case, can we draw any further conclusion. It is arguable that the Court was trying to address the first point - decriminalising non-disclosure where there is no significant risk of transmission. But the real risk here is that this aim will be undermined by the lack of attention to the context in which sexual encounters take place and the failure to specify clearly where responsibilities lie. In fact it is arguable that the finding of the case - restoring the convictions against a black Sudanese immigrant where the female complainants testified about their fears - in fact reinforces the prejudices in this area.
The way forward must surely be shared responsibility for the disclosure and for the consequences of non-disclosure. Where no transmission takes place it is hard to see what is achieved through criminal prosecution - other than the reinforcement of prejudice. And even where there is transmission it is hard to see that the criminal law has a role to play, except in cases where this is deliberate and some overt deception or fraud has been used.
