Switzerland’s highest court – the Federal Court in Lausanne – has ruled that a man who was unaware of his infection is still criminally liable for infecting a woman with HIV.
In effect, the court has ruled that anyone who has had unprotected sex in the past, and does not disclose it to their sexual partner before having unprotected sex with them, may be criminally liable should HIV transmission take place.
An unofficial translation of the article in the Neue Zürcher Zeitung (the original and the translation follow, below) reporting the case, says the following:
..you have to refrain from having unprotected intercourse, if there are concrete indications for a potential HIV infection. Indications can be, in principle, any perceived risky contact in the past, such as unprotected intimate contacts with a person whose sexual past one does not know. In principle the Safer Sex Guidelines of the Federal Health Office are authoritative for this. Irrelevant are the statistical risks of transmission or the fact that signs [of seroconversion] failed to appear.
There are three articles below. First, my article on this published today on aidsmap.com. Then there is a short article in English from swissinfo.ch, and finally the Neue Zürcher Zeitung article (in English and then a jpg of the German original) which contains a lot more information.
I also have a copy of the full judgment in German, which helped inform my article for aidsmap.
I had delayed reporting on this very important case because I had asked the Swiss Federal AIDS Commission (EKAF) to provide an official comment, and to discuss its implications. However, I found out last night that this will not be available until they have their next meeting in September. Nevertheless, I know that some individuals working with EKAF are very concerned about this latest development.

Swiss court rules all people with HIV can be criminally liable for transmission, even if untested
Switzerland’s highest court – the Federal Court in Lausanne – has ruled that a man who was unaware of his infection when he had unprotected sex that transmitted HIV is still criminally liable. The ruling suggests that unprotected sex in Switzerland without first disclosing a sexual history may result in prosecution should HIV be transmitted.In 2006, the California state Supreme Court ruled that ‘constructive knowledge’ – when it is reasonably foreseen by a reasonably intelligent person that their actions could lead to harm – of the possibility that HIV transmission may occur, is enough to allow for civil liability. However, this is the first ruling anywhere in the world to find that an undiagnosed individual may be criminally liable for HIV transmission.
The criminal case, reported in some detail in the July 1st edition of the Neue Zürcher Zeitung, began with a trial in Zurich’s District Court in 2005. The complainant was a woman who had tested HIV-positive after having unprotected sex in 2002 with the defendant. Although the man had not been diagnosed HIV-positive before their sexual encounters, he did have a history of unprotected sex.
Notably, in 2000, he had been informed by a former sexual partner that she had been diagnosed HIV-positive. The man testified that he had not taken an HIV antibody test because he did not believe himself to have been infected during unprotected sex with this woman, based on a lack of seroconversion symptoms at the time. However, the District Court found him guilty under both public health and criminal law.
Swiss criminal HIV exposure and transmission laws
Liability for HIV exposure or transmission in Switzerland is based on two distinct sets of laws – those aimed at protecting the general public (public health law) and those protecting the individual (criminal law).Article 231 of the Swiss Criminal Code allows prosecution by the police – without the need for a complainant – of anyone who “deliberately spreads a dangerous transmissible human disease.” Informed consent to unprotected sex does not nullify the offence, and even the attempt to spread a dangerous transmissible human disease (i.e. HIV exposure without transmission) is also liable to prosecution.
Article 122, also allows prosecution for grievous bodily harm if unprotected sex results in HIV transmission. However, informed consent is a defence in this case, and a prosecution requires a complainant in order to prove that informed consent (i.e. disclosure of HIV status before sex) was not obtained.
In effect, “any unprotected sex of an HIV-positive person is a crime, even if there is no transmission,” Professor Pietro Vernazza, of the Cantonal Hospital in St. Gallen, and President of the Swiss Federal Commission for HIV / AIDS, tells aidsmap.com. In part, it was these draconian laws that motivated the Swiss Federal AIDS Commission’s recent statement regarding antiretroviral therapy’s effect on HIV transmission.
Cantonal Court upholds appeal
The undiagnosed man convicted under these laws appealed to the Zurich Cantonal Court in 2007. The appeal had two parts: questioning whether an undiagnosed person has a legal requirement to test for HIV and to disclose their sexual history; and questioning the validity of the phylogenetic analysis evidence used in the original case.The Cantonal Court ruled that not only was he not liable – because there is no law mandating HIV testing or disclosure after unprotected sex – but also that the scientific evidence was not conclusive enough to prove that he had infected the complainant.
Although phylogenetic analysis of the samples linked the man’s rare HIV subtype to the complainant’s own HIV strain, his lawyers successfully argued that phylogenetic analysis cannot rule out that another individual may have infected the complainant. In addition, phylogenetic analysis ruled out a link between the defendant and the HIV-positive woman with whom he had ‘risky’ sex in 2000.
Federal Court reverses appeal
On June 30th 2008, Switzerland’s highest court ruled that the man can be held responsible for HIV transmission under both public health and criminal law. They said the defendant could not ignore the fact that his own past behaviour was risky, particularly since one of his previous partners had told him she was HIV-positive after they had had unprotected sex.It also ruled that the woman did not have joint responsibility for her HIV infection because she did not give informed consent to the risk of unprotected sex. If she had known the man’s sexual history, it was unlikely she would have had consented to unprotected sex, it said.
An unofficial translation of the German-language article in the Neue Zürcher Zeitung quotes the following: “…you have to refrain from having unprotected intercourse, if there are concrete indications for a potential HIV infection. Indications can be, in principle, any perceived risky contact in the past, such as unprotected intimate contacts with a person whose sexual past one does not know. In principle the Safer Sex Guidelines of the Federal Health Office are authoritative for this. Irrelevant are the statistical risks of transmission or the fact that signs [of seroconversion] failed to appear.”
The Federal Court also overturned the ruling on phylogenetic analysis, saying that since the defendant’s strain was so rare, it would have been highly unlikely that the complainant could have acquired it elsewhere.
In effect, Switzerland’s highest court had now ruled that anyone who has had unprotected sex in the past, and does not disclose it to their sexual partner before having unprotected sex with them, may be criminally liable should HIV transmission take place.
Court rules in HIV case
July 1, 2008
swissinfo.chSwitzerland’s highest court has ruled that a man who unknowingly infected a woman with HIV can be held responsible for his actions.
The Federal Court in Lausanne wrote that any person having occasional sex with another should use a condom to protect the other person. Otherwise they should expect to be accused of causing seriously bodily harm through negligence if the occasional partner is diagnosed with the Aids-causing virus.
The decision overturns an earlier one by Zurich’s cantonal court after an appeal by a woman who was diagnosed with the virus. She had had unprotected sex with a man who did not know he was contaminated.
The man had previously had unprotected relations with other partners, and the country’s highest court ruled that he had failed to apply the rules of safe sex.
Even if he did not know he was HIV positive, the judges said he could not ignore the fact that his own behaviour was risky, especially after one of his earlier partners had admitted being infected.
HIV Transmission After Risky Contacts: Conviction required
Neue Zürcher Zeitung
1 July 2008If you ignore the possibility of being infected with HIV after previously having had risky contacts, and then infect a sexual partner by having unprotected intercourse, you can be prosecuted for reckless greivous bodily harm. The Federal court requires the Zurich cantonal courts to convict a man, who had unprotected intercourse with various women for years.
In 2000, one of his former sexual partners informed him she was HIV-positive. He abstained from having an HIV test done, because he relied on not having been infected due to the lack of signs, such as fever attacks. Two years later he had unprotected sex with another woman, who he didn’t inform about that risk. Later she was diagnosed with having the same rare HIV strain as he did.
The Zurich cantonal court fully acquitted the man in March 2007 of the accusation of reckless greivous bodily harm and reckless spreading of human diseases, following an earlier convicion. The court had negated the recklessness of the act, claiming that there is no legal obligation to test for HIV after having had unprotected intercourse.
The Penal Department of the Federal court has now approved of the victim’s remonstrance and sent the matter back to the Cantonal court for the conviction of the man. According to the adjudication from Lausanne, as for the question of recklessness, it is decisive that you have to refrain from having unprotected intercourse, if there are concrete indications for a potential HIV infection. Indications can be, in principle, any perceived risky contact in the past, such as unprotected intimate contacts with a person whose sexual past one does not know. In principle the Safer Sex Guidelines of the Federal Health Office are authoritative for this. Irrelevant are the statistical risks of transmission or the fact that signs [of seroconversion] failed to appear.
The Lausanne judges answered their Zurich colleagues back on another point. The Cantonal court’s perception that the woman could have been infected indirectly via a chain of persons with the relevant virus type, is highly unlikely and therefore indefensible, according to the Lausanne judges.
Finally even a joint responsibility of the woman was negated. If she had known the preliminary history of her sexual partner, she would hardly have had consented to having unprotected intercourse, says the Federal court.
