South Australians are being urged to have their say on the proposed law reforms developed in the wake of the tragic killing of Millicent woman Synamin Bell.

Ms Bell was killed by her partner after he had consumed hallucinogenic drugs.

Last week, her killer was sentenced to 11 years in jail with a non-parole period of eight years and ten months.

While he had been charged with murder, he ultimately pleaded guilty to a charge of manslaughter.

As a result, the Government has prepared reforms to the law which would prevent the partial defence of excessive self-defence from being used in murder cases where the accused was substantially affected by self-induced intoxication.

Consultation on the draft legislation closes on October 7, with South Australians able to comment on the proposed reforms by visiting www.yoursay.sa.gov.au/excessiveselfdefence(external site).
