The Extradition Bill refers to proposed legislation in Hong Kong that aimed to allow the transfer of fugitives to jurisdictions with which it does not have formal extradition agreements, including Mainland China. The bill raised concerns about the potential erosion of Hong Kong's legal autonomy and the risk of political persecution. In 2019, widespread protests erupted in response to the bill, with many citizens fearing it would undermine their freedoms. The government eventually suspended the bill, but the protests highlighted broader issues regarding Hong Kong's relationship with China and the preservation of its unique legal system.
