in particular those applicable to euthanasia - distinguishable into substantive
requirements (conditions of legal euthanasia) and procedural requirements (zorg-
vtddigheidseisen sometimes refers more narrowly to these latter requirements). Since
absence of zorgvuldigheid is the basis of liability for a negligent tort and thus equiva-
lent to the Common Law idea of lack of‘due care’, one might translate the Dutch
term as ‘requirements of due care’. However, this would wrongly suggest a connec-
tion with tort liability, which is the reason we have preferred to translate the term as
‘requirements of careful practice’.'
I personally think 'due care/due diligence' covers it nicely in this context.
