Ai Weiwei had deposited 1.33 million in a government-controlled account in order to appeal. Ai said he will not pay the remainder because he does not recognize the charge.
Were all the charges of the case dropped against Ai Weiwei?
On 27 September, the court upheld the 2.4 million tax evasion fine.
So what happened to Ai Weiwei after the court decision that upheld the 2.4 million tax evasion fine?
In October 2012, authorities revoked the license of Beijing Fa Ke Cultural Development Ltd. for failing to re-register, an annual requirement by the administration.
