Repeal Existing Policies that Encourage and Allow Legal HIV Discrimination Act of 2022 or the REPEAL HIV Discrimination Act of 2022 This bill addresses federal and state laws, policies, and regulations that may burden people living with HIV/AIDS. Specifically, the bill directs the Department of Justice (DOJ), the Department of Health and Human Services (HHS), the Department of Defense (DOD), and the White House Office of National AIDS Policy to initiate a national review of federal (including military) and state laws, policies, regulations, and judicial precedents and decisions regarding criminal and related civil commitment cases involving people living with HIV/AIDS. DOJ must transmit to Congress and make publicly available the results of such review with related recommendations. The White House Office of National AIDS Policy must also develop and publicly release guidance to assist states with handling relevant cases. The office, DOJ, HHS, and DOD must transmit to the President and Congress any proposals necessary to implement adjustments to federal laws, policies, or regulations. This bill shall not be construed to discourage the prosecution of individuals who act with the intent to do harm to another individual by intentionally transmitting HIV.
