We applaud the declaration of the Supreme Court of Justice of the Nation, which gives us the reason for the unconstitutionality request, shared with the National Commission of Human Rights; For this reason, we suggest to the deputies of the Congresses of the State that before legislating, they should be trained in the subject and that they do not forget that their obligation is to defend Human Rights, not to violate them.
Finally, the Mexican Network against the Criminalization of HIV recognizes that there are still many ways to go and many battles to fight, but we can not stop celebrating this important achievement.
HIV JUSTICE WORLDWIDE
This is a letter of support from HIV JUSTICE WORLDWIDE to Grupo Multi VIH de Veracruz / National Commission of Human Rightswho are challenging Article 158 of Penal Code of the Free and Independent State of Veracruz that criminalises "intentional" exposure to sexually transmitted infections or other serious diseases, on the grounds that this law violates a number of fundamental rights: equality before the law; personal freedom; and non-discrimination.
As a coalition of organisations working to end the overly broad use of criminal laws against people living with HIV, we respectfully share Grupo Multi VIH de Veracruz's concerns around Article 158 which potentially stigmatises people with sexually transmitted diseases and criminalises "intentional" exposure to sexually transmitted infections (potentially including HIV) or other serious diseases.
All legal and policy responses to HIV (and other STIs) should be based on the best available evidence, the objectives of HIV prevention, care, treatment and support, and respect for human rights. There is no evidence that criminalising HIV "exposure" has HIV prevention benefits. However, there are serious concerns that the trend towards criminalisation is causing considerable harm.
Numerous human rights and public health concerns associated with the criminalisation of HIV non-disclosure and/or potential or perceived exposure and/or transmission have led the Joint United Nations Programme on HIV/ AIDS (UNAIDS) and the United Nations Development Programme (UNDP), the UN Special Rapporteur on the right to health, the Global Commission on HIV and the Law and the the World Health Organization, to urge governments to limit the use of the criminal law to extremely rare cases of intentional transmission of HIV (i.e., where a person knows his or her HIV-positive status, acts with the intention to transmit HIV, and does in fact transmit it). They have also recommended that prosecutions [for intentional transmission] "be pursued with care and require a high standard of evidence and proof." 
In 2013, UNAIDS produced a comprehensive Guidance Note to assist lawmakers understand critical legal, scientific and medical issues relating to the use of the law in this way. In particular, UNAIDS guidance stipulates that:
- "[I]ntent to transmit HIV cannot be presumed or solely derived from knowledge of positive HIV status and/or non-disclosure of that status.
- Intent to transmit HIV cannot be presumed or solely derived from engaging in unprotected sex, having a baby without taking steps to prevent mother-to-child transmission of HIV, or by sharing drug injection equipment.
- Proof of intent to transmit HIV in the context of HIV non-disclosure, exposure or transmission should at least involve (i) knowledge of positive HIV status, (ii) deliberate action that poses a significant risk of transmission, and (iii) proof that the action is done for the purpose of infecting someone else.
- Active deception regarding positive HIV-status can be considered an element in establishing intent to transmit HIV, but it should not be dispositive on the issue. The context and circumstances in which the alleged deception occurred -- including the mental state of the person living with HIV and the reasons for the alleged deception -- should be taken into consideration when determining whether intent to transmit HIV has been proven to the required criminal law standard."
Moreover, where criminal liability is extended to cases that do not involve actual transmission of HIV (contrary to the position urged by UNAIDS and other experts), such liability should, at the very bare minimum, be limited to acts involving a "significant risk" of HIV transmission. In particular, UNAIDS guidance contains explicit recommendations against prosecutions in cases where a condom was used, where other forms of safer sex were practiced (including oral sex and non-penetrative sex), or where the person living with HIV was on effective HIV treatment or had a low viral load. Being under treatment or using other forms of protections not only show an absence of malicious intent but also dramatically reduces the risks of transmission to a level close to zero. Indeed, a person under effective antiretroviral therapy poses -- at most -- a negligible risk of transmission and is therefore no different from someone who is HIV-negative.
Moreover, there is growing body of evidence that such laws that actually or effective criminalise HIV non-disclosure, potential or perceived exposure, or transmission, negatively impact the human rights of people living with HIV due to:
- selective and/or arbitrary investigations/prosecutions that has a disproportionate impact on racial and sexual minorities, and on women.
- confusion and fear over obligations under the law;
- the use of threats of allegations triggering prosecution as a means of abuse or retaliation against a current or former partner;
- improper and insensitive police investigations that can result in inappropriate disclosure, leading to high levels of distress and in some instances, to loss of employment and housing, social ostracism, deportation (and hence also possibly loss of access to adequate medical care in some instances) for migrants living with HIV in some cases;
- limited access to justice, including as a result of inadequately informed and competent legal representation;
- sentencing and penalties that are often vastly disproportionate to any potential or realised harm, including lengthy terms of imprisonment, lifetime or years-long designation as a sex offender (with all the negative consequences for employment, housing, social stigma, etc.);
- stigmatising media reporting, including names, addresses and photographs of people with HIV, including those not yet found guilty of any crime but merely subject to allegations.
In addition, there is no evidence that criminalising HIV (or other sexually transmitted infections) help protect women and girls from infections.
Women are often the first in a relationship to know their HIV status due to routine HIV testing during pregnancy, and are less likely to be able to safely disclose their HIV-positive status to their partner as a result of inequality in power relations, economic dependency, and high levels of gender-based violence within relationships.
Such a law does nothing to protect women from the coercion or violence that effectively increases the risk of HIV transmission. On the contrary, such laws place women living with HIV, especially those in vulnerable positions and abusive relationships, at increased risks of both prosecution and violence.
Some evidence suggests that fear of prosecution may deter people, especially those from communities highly vulnerable to acquiring HIV, from getting tested and knowing their status, because many laws only apply for those who are aware of their positive HIV status. HIV criminalisation can also deter access to care and treatment, undermining counselling and the relationship between people living with HIV and healthcare professionals because medical records can be used as evidence in court.
Finally, there is evidence of an additional negative public health impact of such laws in terms of:
- increasing HIV-related stigma, which has an adverse effect on a person's willingness to learn about, or discuss, HIV; and
- undermining the importance of personal knowledge and responsibility (correlative to degree of sexual autonomy) as a key component of an HIV prevention package, when instead prevention of HIV within a consensual sexual relationship is -- and should be perceived as -- a shared responsibility.
We hope that the Mexico Supreme Court of Justice takes our concerns and all of this evidence into account when considering the Constitutional Challenge.
