The Supreme Court will begin hearing arguments today concerning the obligations of those infected with the virus that causes AIDS.
At issue is whether it's a crime for people with HIV to keep their condition from their sexual partners if the risk of transmission is low.
The justices will hear appeals that involved a man living in Manitoba and a Quebec woman who had their cases overtuned.
Prosecutors argue people carrying HIV must always inform their partners regardless of the risks of transmission.
That way partners can decide if they want to run the risk of contracting the virus.
Advocates for people with HIV say this thinking criminalizes carriers of the virus and doesn't acknowledge the science that can determine the likelihood of transmission.
All are looking to the Supreme Court to clarify the law and update a high court ruling from 1998 which has been interpreted differently by judges across the country ever since.
