New Zealand Police v Justin William Dalley

Clarifies that use of a condom satisfies the requirement to take ‘reasonable care’ to prevent HIV transmission during vaginal sex, and that ‘failsafe’ precautions are not required by law. Also finds that oral sex without a condom (and without ejaculation) satisfies the standard of  ‘reasonable care and precautions’. This ruling means that disclosure of HIV status before vaginal sex is not required as long as a condom is used. Disclosure before oral sex is not required.
