Northern Territory Consolidated Acts18. Belief by accused that infant was of age
In proceedings for an offence against section 13, 14(1) or (2), 15(1) or 16, it is not necessary for the prosecution to prove that the accused knew that the person concerned was an infant, but it is a defence for the accused to prove that, having taken all reasonable steps to find out the age of the person concerned, the accused reasonably believed at the time when the offence is alleged to have been committed that the person had attained the age of 18 years.
