The government says it will work on finding additional care places for abused children, as more cases are expected to come to light in the city thanks to a new law passed by Legco on Thursday.

The Mandatory Reporting of Child Abuse Bill sets out how 25 types of professionals, including doctors, social workers and teachers, will face a maximum punishment of three months in prison and a HK$50,000 fine if they fail to tell the authorities when they suspect a child is suffering physical, psychological or sexual abuse.

The bill was introduced last year following a series of abuse scandals which sparked calls for more protection for children.

Seventy-nine lawmakers voted in favour of the new law, with no opposing votes and one abstention.

Secretary for Labour and Welfare Chris Sun said the legislation will come into effect 18 months after it is gazetted.

“We're going to make use of the coming 18 months to make sure that everything is ready so that by the time the legislation comes into effect, all the professions who are required under the law to make mandatory reporting will get the necessary training," Sun said.

“We're also at the same time putting in place additional facilities and homes to cater for the increasing cases of reporting. And also, we're going to step up our efforts in terms of promotion and publicity, and make sure that we all work together for the welfare and betterment of our children.”

During Thursday's debate on the bill, Roundtable lawmaker Michael Tien proposed a higher maximum punishment of one year in prison for those who fail to report abuse suspicions, saying the three-month term doesn't reflect the seriousness of such an offence.

“Did you ask the children’s thoughts? Did you only ask the professionals’ thoughts? We have one million children in Hong Kong. I think we won’t have one million professionals,” he said.

Tien also argued that the courts rarely hand out the maximum sentence possible.

In response, Sun said the penalty level is the same as for other mandatory reporting laws.

“These include the reporting of drug trafficking, terrorism, and organised crime. The government believes the deterrent effect of the penalty is already sufficient and appropriate to the crimes involved,” he said.

Social welfare sector lawmaker Tik Chi-yuen, meanwhile, lauded the government for adding more exemptions and immunity clauses in the bill, as well as for forming consultant groups to create a “report manual”.

Tik said these moves had addressed concerns raised by professionals regarding the bill.
