A bill aimed at keeping repeat offenders with a history of violent crimes and sexual offences in check passed its third and final reading by the House of Representatives.
The bill passed with 320 MPs voting in favour on Wednesday, Patcharin Samsiriphong, a Palang Pracharath Party (PPRP) MP and party spokeswoman said.
The bill, which has 43 sections, will be forwarded to the Senate for further consideration.
The bill was proposed by the Justice Ministry to reduce the number of repeat offenders by focusing on those involved in violent crimes and sexual violence.
Based on the Department of Corrections' 2018-2021 figures, 34.6% of ex-convicts repeat their offences.
Under the bill, repeat offenders in violent crime will be subject to surveillance after prison for public safety and as part of the former inmates' rehabilitation.
Ms Patcharin said the bill allows for anti-libidinal medication, or chemical castration, with the consent of the convicts.
They will be barred from leaving the country, must inform authorities when changing workplaces and wear electronic monitoring bracelets, she said.
Justice Minister Somsak Thepsutin, who chaired a House committee scrutinising the bill, said the committee took opinions from the Justice Ministry, the Council of State, which is the government's legal advisory body, the Corrections Department, and the Office of the Attorney-General.
Studies on how to curb violence by repeat offenders were also taken into account, Mr Somsak said.
Surapong Kongchantuek, an ex-member of the National Human Rights Commission, said the bill will help build a safer society.
