HIV-Specific Criminal Laws

There are no statutes explicitly criminalizing HIV transmission or exposure in Montana. 

For detail on the selected state law and cases interpreting it, see Montana: Analysis & Codes, an excerpt from CHLP’s recently updated compendium of HIV- and STI-related criminal laws and civil laws relating to public health control measures in all 50 states, the military, and U.S. territories. To view the publication in its entirety, see HIV Criminalization in the United States:  A Sourcebook on State and Federal HIV Criminal Law and Practice. Methodology is explained in the Introduction (page 5).

General STI/Communicable Disease Laws that Include HIV:

It is a misdemeanor for a person with an STI (including HIV) to “knowingly” expose another to that disease.

General STI statute potentially applied to HIV.

General Felony Laws Used Against PLWH:

There has been at least one prosecution of HIV exposure under general criminal laws in Montana.

We currently are in the process of reviewing and updating our resources and summaries related to health care workers and disclosure. In the meantime, please do not rely on this information as current, and get in touch with CHLP with any questions.

Health Department Policies:

"Health care provider" means a person who is licensed, certified, or otherwise authorized by the laws of this state or who is licensed, certified, or otherwise authorized by the laws of another state to provide health care in the ordinary course of business or practice of a profession. The term does not include a person who provides health care solely through the sale or dispensing of drugs or medical devices.

Calls for Voluntary Testing of Health Care Workers with HIV:

Voluntary Testing.

Practice Restrictions Based on HIV Status/"Exposure-Prone Procedures":

Local review panels will be developed on a case-by-case basis as specific problems arise. The panel will consider the following: (a) whether HCW performs procedures in which injury could result in contamination of a patient’s body cavity, subcutaneous tissues, and/or mucous membranes by the HCW’s blood; (b) factors affecting the performance of procedures by HCW (e.g., techniques used, skill and experience, and compliance with recommended infection control practices); and (c) the medical condition of HCW (e.g., presence of physical conditions or mental impairments that may interfere with the HCW’s ability to perform those procedures safely).

These summaries highlight key aspects of state laws governing the rights of minors to consent to testing and/or treatment for sexually transmitted infections (STIs) and HIV. Any such summary cannot capture the details and nuances of individuals state laws. Although roughly a third of the states permit health care providers to inform a minor's parents that their child is seeking STI-related services, none require it. Also, the law is fluid, and these summaries may not reflect recent legislative change in a particular state.  

Every state in the country allows minors to consent to STI testing and care without parental approval, although a number of these set an age threshold for the right to consent without parental involvement. In these states, the minimum age ranges from 12 to 14 years of age. 

As of the date of this posting, thirty-one states allow minors to also consent to HIV testing and treatment without parental approval. 

Physician May Inform Parent of Minor's HIV Status:

Physician may, but is not required to, inform parents.

Unlike testing for most other infectious diseases, testing for HIV involves possible benefits as well as social, economic, and legal consequences that typically are not apparent or known to an individual considering testing. HIV-related testing is the gateway to health-preserving treatment; it also can be the basis of criminal prosecution for those who are sexually active, or relied on to exclude individuals who test positive for HIV from programs, employment, or insurance. Although state and federal laws prohibit much of this discrimination against people with HIV, the ability to enforce those rights usually depends on access to free legal services, which are increasingly limited and not available at all in roughly half of the states in the United States. Thus, the potential negative consequences of HIV testing at a particular time or location might inform an individual's decision of whether or when to get tested for HIV; or whether to test anonymously or through a "confidential" testing process that reports their test results and identifying information to the state but maintains the confidentiality of those results.  

The American Medical Association has long defined informed consent as a process of communication between a patient and physician that results in the patient's authorization or agreement to undergo a specific medical intervention. Although informed consent is a legal concept rather than a medical one, many states use definitions of "informed consent" for purposes of HIV testing and medical procedures that in fact are inconsistent with the accepted legal definition, e.g., they do not require that an individual receive information or sometimes even notification that they are about to be tested for HIV. The Center for HIV Law and Policy (CHLP) accepts the legal and court-affirmed definition of informed consent; therefore, state protocols that call for "opt-out" testing (a patient is tested for HIV unless she/he objects) or that mirror general consent approaches are not counted as "informed consent" laws even in those instances where the state legislature has characterized their state law as requiring "informed consent." In short, CHLP does not consider or count laws that allow a patient's silence or general consent as granting authority to do confidential HIV testing as informed consent laws.
