In recent years concern about Foetal Alcohol Spectrum Disorder (FASD) has intensified, prompting calls for societal action. Pregnant women's consumption of alcohol is increasingly surveilled, public health campaigns now promote abstinence, and in some jurisdictions, prenatal alcohol exposure (PAE) resulting in FASD has received criminal sanction. This paper anticipates potential calls to criminalise PAE resulting in FASD by envisioning what such a case might look like. Applying Duff et al's framework for determining whether an act should be criminalised, we draw upon public health and jurisprudential discourses to trace the outline of an argument for framing maternal alcohol consumption causing injury to the child born alive as a public wrong and a crime.1 We show how an ‘in principle’ case may be constructed, but argue that countervailing principles, including women's rights, and practical considerations, tell decisively against criminalisation.
