Switzerland: How effective HIV treatment has impacted upon the criminalisation of HIV exposure

The preventative effect on HIV transmission of being virally suppressed due to antiretroviral therapy (ART), as recognized by the Swiss Commission for HIV/AIDS in 2008, has helped to reduce the criminalization of HIV exposure in Switzerland. Since the Swiss statement’s release, there have been acquittals of two HIV exposure cases in 2009, no further prosecutions for HIV exposure and alterations to the law used in these cases, according to study results presented at EACS 2013 in Brussels, Belgium.

Although Switzerland is not the only country to criminalize HIV, the country did have one of the most severe HIV criminal legislation in Europe, together with Sweden and Austria. Swiss law had considered exposure to HIV, defined as sex without a condom between an HIV-infected individual and an HIV-uninfected individual, a criminal offense. This was the case even if the HIV-uninfected partner gave consent, there was no transmission or the HIV-infected partner did not know his or her status.

The criminal cases were based in two articles of the Swiss penal code: 122, which concerns serious bodily harm, and 231, which covers transmission of human diseases. The latter, despite supposedly being a public health measure, had only been invoked in cases of HIV exposure or transmission. From 1990 onward, this legal apparatus had resulted in more than 80 proceedings, with 48 prosecutions — over half of them due to exposure only, with no transmission having happened.

This scenario started changing in 2008, according to Deborah Glejser and Sascha Moore Boffi, from Groupe Sida Genève, a Swiss community-based HIV organization. Glejser performed a survey that reviewed criminal judgments in Swiss cantonal and federal courts, statements by stakeholders and policy makers and records of parliamentary sessions since 2009. Glejser states that the turning point for advocacy work against criminalization was the declaration issued by the Swiss Commission for HIV/AIDS (now known as the Swiss Commission for Sexual Health) in 2008.

The Swiss statement, as it became known, stated that “HIV-positive individuals on effective antiretroviral therapy who have had an undetectable viral load for at least six months and without sexually-transmitted infections are sexually non-infectious.” Due to the worldwide controversy created by the declaration, it was not immediately used in court, with Swiss prosecutors trying to have it removed from debates so as not to be used as a defense. Although there was international acknowledgement of the Swiss statement in 2009, advocacy groups did not wait for it, using policy briefs by UNAIDS to show that criminal laws against HIV transmission had no impact on the spreading of the virus or containment of the epidemic.

A breakthrough came in December 2008 in the case of an HIV-infected man who was condemned to a year and a half of prison by a Geneva court. The man knew he had an undetectable viral load and had sex with two consenting HIV-uninfected women. Although no transmission occurred, the two women sued the man, who appealed the sentence. Three months later, the court cleared him of the charges stating that he was undergoing ART at the time and had little chance to infect his partners. This was the first decision of its kind in Switzerland, but not the only one. A second acquittal happened in 2009. Since then, no further prosecutions have been carried out for HIV exposure when the HIV-infected partner was on effective ART.

For Glejser, these acquittals were a major step forward and set a legal precedent, leading to a significant decrease in the number of prosecutions after 2009. This was supported in later years by changes in legislation, such as the 2012 reformation of article 231, preventing prosecution when informed consent is given. With the new wording, the article will only be invoked for intentional or malicious transmission.

HIV exposure can still be prosecuted under article 122, but thanks to a 2013 ruling by the Swiss federal court (equivalent to the U.S. Supreme Court), HIV transmission is no longer considered serious bodily harm, falling under common assault and making it easier for defendants to use the Swiss statement for defense, as well as resulting in lesser sentences.

Canada: Nova Scotia court acquits young man with undetectable viral load of aggravated sexual assault for HIV non-disclosure despite no condom use

by Cecile Kazatchkine, Senior Policy Analyst, Canadian HIV/AIDS Legal Network

On November 8 2013, the Provincial Court of Nova Scotia in Canada released a very encouraging decision in a case of HIV non-disclosure. A young man with an undetectable viral load who had not disclosed his HIV positive status to his sexual partner before engaging in unprotected sex was acquitted of aggravated sexual assault.

The couple had engaged in vaginal sex on three occasions. Twice, they used a condom. On the third occasion, however, it was found that they had unprotected vaginal sex without ejaculation. At no time, did the young man disclose his HIV status. In fact, the judge found that he had actively concealed that he was HIV positive to his sexual partner who had inquired about rumours that he had AIDS.

In 2012, the Supreme Court of Canada ruled in R. v. Mabior and R. v. D.C., that a person living with HIV has a legal duty to disclose his or her HIV positive status to a sexual partner where there is a “realistic possibility of HIV transmission.” The Supreme Court was clear that where a condom is used and the HIV positive partner has a low viral load, there is no “realistic possibility of HIV transmission” and thus, no duty to disclose under the criminal law. These decisions were understood to mean that a person living with HIV must disclose his or her HIV positive status before having vaginal sex unless he or she uses a condom and has a low viral load.

None the less, the Provincial Court of Nova Scotia acquitted the young man, despite the factual finding that he had engaged in unprotected sex. The Court described two different routes to its conclusion.

The first route relates to the analysis of the consent given by the complainant. In Canada, one element that the prosecution must prove in a non-disclosure prosecution is that the complainant would not have consented to sex if he or she had known about his or her partner HIV positive status. At trial, the complainant testified that had she known that the accused was HIV positive she would not have had unprotected sex with him. But she also said that had she known that his risk of transmitting HIV was virtually non-existent, she would have consented.

As described by Justice Campbell, that the risk of transmission was infinitesimally small was the “true state of affairs” based on the evidence before the Court. Indeed, the unchallenged medical expert called by the defence testified that he did not believe that there was any risk of transmission in this case. He further concluded that “in an act of sexual intercourse someone with an undetectable viral load such as [the accused] had a one in one million chance of transmitting the virus. That might be as high as one in 500 000 (…)” and described the risk as “very close to zero.”

According to the Court, the complainant’s statement that had she known the extremely low degree of risk she would have consented to unprotected sex with the accused is part of the context that needs to be taken into account when determining whether the consent was vitiated or not. As summarised by Justice Campbell:

[t]o ignore [the complainant]’s acknowledgement that with full knowledge of the facts she would have had unprotected sex with [the accused] would amount to a strange privileging of half-truth, deception and misconception over truth. The truth is that she would have had unprotected sex with him had she known the facts. My conclusion is that her consent was not vitiated by the deception.

The second route relates to the realistic possibility of transmission. The Court found that that element had not been met either. This conclusion is at odds with the predominant interpretation of Mabior and D.C. — that unprotected sex, even with an undetectable viral load, would necessarily be considered as representing a “realistic possibility of transmission.”

In a recent decision, the Ontario Court of Appeal had ruled that there was no need for the Crown to bring medical evidence of “a realistic possibility of transmission” in each case. The Court of Appeal ruled that proving unprotected sex would be sufficient to establish “a realistic possibility of transmission” and that evidence of the accused’s exact viral load at the time and the associated degree of risk of HIV transmission would be irrelevant in such circumstances. (There was no medical evidence on the risks of transmission before the Ontario Court of Appeal or evidence of the accused’s viral load.)

The Provincial Court of Nova Scotia, however, did not accept that the Supreme Court of Canada or the Ontario Court of Appeal decisions had definitely closed the doors to different findings with respect to whether “a realistic possibility of HIV transmission” existed based on the medical evidence before the judge in a particular case.  Concerned about the potential for discrimination against people living with HIV in the absence of any risk, the Provincial Court of Nova Scotia stated that the Supreme Court decisions “can and should be interpreted in a way that in not incompatible with an approach that respects both the scientific evidence in each case and the fact finding role of trial courts.”  According to the Court, “[t]he Supreme Court did not intend (…) to impose evidentiary findings on trial courts that are incompatible with the evidence actually before those courts.”

In the case at bar, the medical evidence called by the defence was clear: the risk of transmission was approaching zero. The Court was careful to specify the risk determination was a finding of fact (versus a finding of law), specific to the case, and ruled that the legal conclusion arising from that fact was that, even in the absence of a condom, the legal test of a “realistic possibility of transmission” was not met.

This decision is an encouraging development in the law on HIV non-disclosure in Canada. While trial court decisions have limited precedential authority in the Canadian legal system, this decision remains important as it demonstrates that Mabior and D.C — which have been strongly criticised for being at odds with the science and previous case law — need not prevent science from prevailing over prejudice. Medical evidence can and should play a critical role in cases of HIV non-disclosure, exposure and transmission, something both defence lawyers and medical experts in HIV will need to be very mindful of.

R. v. J.T.C. 2013 NSPC 105 (November 8 2013)

Sweden: Court of Appeal acquits ‘HIV exposure’ case, recognises National Board of Health and Welfare endorsement of ‘Swiss statement’, Minister for Social Affairs will consider reviewing application of law

Today, the Court of Appeal for Skåne and Blekinge has acquitted a man from Malmö previously convicted of exposing four women to HIV on the grounds that since he had a stable undetectable viral load on antiretrovirall treatment with no other STIs he could not cause danger to another person.

He had previously been sentenced to a year in prison and and fined 150,000 kronor (€17,000) by the lower court, but was released last week pending the appeal after the Court consulted experts from the Swedish Institute for Communicable Disease Control (SMI).

A press release from the Swedish Courts notes the following (unofficial translation)

The Court of Appeal, for its assessment of the probability of transmission by sexual intercourse, had access to information other than that which existed at the district court. The Court of Appeal has obtained an expert opinion from the Swedish Institute for Infectious Disease Control (SMI) regarding the risk of transmission of HIV through unprotected sexual intercourse. Furthermore, Professor Jan Albert of the Karolinska Institute, was consulted as an expert.

For expert opinion and data Jan Albert has said it can be clearly concluded that the risk of transmission of HIV in vaginal intercourse without a condom is very low, provided that the HIV-infected party is on stable HIV treatment. For an HIV-positive patient to be considered to be on stable HIV treatment, as is apparent from the opinion, it requires that the patient has a consistently high adherence to their medication, that at least two consecutive viral measurements with 3-6 month intervals show that patient’s virus levels in the blood were below the lowest detectable levels in routine testing, and the patient does not carry any other sexually transmitted infection .

The Court of Appeal noted in its judgment that the investigation did not show anything other than the accused was on stable HIV treatment during the time that the charges related to, and based on what the SMI and Jan Albert have said about risk of infection, assessing the likelihood that sexual intercourse to which the charges relate means that the risk of HIV transmission was so small that no real danger could be presupposed. Since this does not meet the required elements of the crime of creating danger to another, the indictment was dismissed.

Major policy shift

The ruling reflects a major shift in policy announced last week by the National Board of Health and Welfare (Socialstyrelsen).

In a press release entitled, ‘Effective treatment reduces the risk of infection by HIV’, the agency, which is part of the Swedish Ministry of Health and Social Affairs, clarified the treating physician and the individual’s responsibility under the Communicable Diseases Act – which creates a ‘disclosure obligation’ for anyone with an infectious disease.

The criteria to not be legally bound to disclose are very similar to those set out in January 2008 by the Swiss Federal AIDS Commission’s ‘Swiss statement’. They are, as follows:

For treatment of HIV infection to be considered well-functioning, patients must be highly adherent to antiretroviral treatment. Virus levels in the blood should be tested regularly, verified by two measurements between three to six months apart and the result should be virus levels below 50 copies per milliliter.

Follow-up tests should be performed two to four times a year. No other ongoing sexually transmitted disease should be suspected, as this could increase the risk of infection. When these criteria are met, the SMI estimates that infectivity is minimized in a person infected with HIV similar to wearing a condom during sexual intercourse.

HIV infection is one of the dangerous diseases included under the Communicable Diseases Act. The law states that the attending physician has the responsibility to advise people with dangerous diseases of appropriate conduct. It also says that if the person knows, or has reason to suspect, that he or she is carrying a contagious disease that person is obliged to protect others from infection.

The attending physician, when he or she takes a position on the conduct that the individual should have, should consider that a person with HIV infection who is on well functioning treatment is not required to inform their sexual partners about their infection…

People who have HIV infection, however, must act on their own initiative if there is a significant risk, for example if he or she also gets another sexually transmitted infection. This is true no matter what advice the person has previously received by their treating physician. A significant risk includes situations when someone risks coming into contact with his or her body fluids, for example during blood tests, at the dentists, or during sex with a risk of bleeding.

Coaltion of HIV experts

The National Board of Health and Welfare was itself influenced by a coalition of HIV experts. An editorial by Johan Carlson (Director of SMI), Anders Tegnell  (State epidemiologist, SMI), Jan Albert (Professor of Communicable Diseases, Karolinska Institute and Senior Physician at Karolinska University Hospital) and

Anders Sönnerborg (Professor of Clinical Virology,Karolinska Institut and Senior Physician at Karolinska University Hospital) entitled ‘HIV is no longer a life-threatening disease’, also published last week, heralded this new (for Sweden) paradigm.

Today, 21 October, SMI publishes along with Reference Group for Antiviral Therapy (RAV) a report summarising the state of knowledge with regard to the significant reduction in infectivity in treated HIV infection.

SMI and RAV estimates that the infectivity of a patient living with HIV and who have been stabilized on treatment is very low by sexual contact and minimal if a condom is used in vaginal and anal intercourse. This applies provided that there is no other sexually transmitted infections that can affect the risk of HIV transmission. It is therefore important to always use a condom, especially to protect against other sexually transmitted infections, but also to minimize any residual infectious risk for HIV.

This knowledge provides two important conclusions. Firstly, we improve the chances of early diagnosis and initiate treatment as early as possible…

The second conclusion is that current knowledge about HIV will have to influence society’s attitudes to and treatment of people living with HIV. Knowledge about HIV, how the virus is transmitted and what it means to live with HIV, need to be improved in the whole society. Especially within the health care and disease control work, but it is equally important in other areas of society, such as education and social services, the media and the judiciary.

Minister for Social Affairs will consider reviewing application of law

Göran Hägglund, Sweden’s Minister for Social Affairs reacted to the report by telling Sweden’s public broadcaster, SVT, that he will consider reviewing the application of law as it relates to HIV non-disclosure, exposure and transmission.

“If you have an illness that has the potential to infect, it is reasonable to disclose,” he said. “I just think that one would like to know in this situation. But the application of law is another question. Where it is possible to discuss how the law looks and applied, it may be time to consider a change.”

This policy shift is a major victory for the advocates who have been working tirelessly to change Sweden’s draconian attitude towards people living with HIV, notably the partnership of RFSU (the Swedish Association for Sexuality Education), HIV-Sweden and RFSL (the Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights) who have been lobbying and campaigning to raise awareness and advocate against Sweden’s over-punitive HIV-related policies.

Hägglund also reacted to a recently-published editorial by Marielle Nakunzi, a lawyer at RFSU, which argued that the justice system has such an outdated view of HIV that it still lives in the 1980s.

“It is a matter of making sure that we always have laws that are in tune with the state of knowledge available,” he told SVT. “Therefore, we should always consider the knowledge we have. It’s about educating the justice system.”
