A renewed push to wind back Victoria's abortion laws has been rejected by the Andrews government, which says the matter has already been settled by State Parliament.

Seven years after abortion was decriminalised in Victoria, Democratic Labour Party MP Rachel Carling-Jenkins has drafted a private member's bill attempting to overhaul the law.

Under the proposal – which the DLP says is the first of several plans to change legislation - women who are more than 20 weeks' pregnant would not have the right to an abortion except in the case of a medical emergency. And doctors who carried out an abortion in breach of the new rules could face prosecution and jail terms up to 20 years.

"This protects women from the awful physical and mental consequences of late-term abortion and it protects children," Dr Carling-Jenkins told the crowd at the annual March for the Babies rally at Parliament. "Women deserve better. Abortions don't solve problems – they create them."
