These sections prevent a court from awarding damages for a financial loss suffered in rearing a healthy child. This effectively prevents a decision awarding the same damages that were awarded in Cattanach v Melchior being awarded again in Queensland - however, the amendment does not prevent a successful Wrongful Birth claim.
The new law prohibits courts from awarding damages for financial losses related to raising a healthy child.  This means that a case like the one in Cattanach v Melchior will not be able to be replicated in Queensland, but it doesn't stop wrongful birth claims from being successful.
