On 22 July 1999, the Chinese Communist Party (CCP) banned Falun Gong as “a threat to social and political stability” after 10,000 members staged a protest in Beijing urging for legal recognition. The number of followers – estimated to be in the tens of millions inside China back then – and their ability to stage large protests spooked the Party, prompting the ban.
The CCP used Article 300 of the Criminal Code to target them, which criminalizes “organizing or exploiting mystic sects or cult organizations, or using superstition to undermine the implementation of the nation's laws and administrative provisions.” A maximum of seven years is set for those found guilty, while there is no cap for “serious” cases.
There is also evidence that many practitioners died in custody – some harvested for their organs – while many others were persecuted from outside the judicial system and sent to horrific terms in labour camps or psychiatric detention.
In June 1999, before the ban, a Party organization, the 610 Office, was secretly set up to oversee the eradication of Falun Gong in China. The 610 Office was likely responsible for deciding on sentence lengths for those accused of Article 300 crimes. It appears to have been disbanded in 2018.
