Chinese artist and dissident Ai Weiwei has again failed in a bid to challenge a tax evasion fine he says is politically motivated.
Tax authorities imposed a 15m yuan ($2.4m, £1.5m) fine on Mr Ai's firm for tax evasion in 2011.
His appeal was rejected in July and on Thursday a Beijing court rejected his challenge to that decision.
Mr Ai, who says he remains unable to leave the country, described the decision as "shameless".
"It didn't respect the facts or give us a chance to defend ourselves; it has no regard for taxpayers' rights," Reuters news agency quoted him as saying.
The artist, a outspoken critic of the government, was detained for almost three months without charge last year.
After he was released, he was accused of tax evasion and the fine imposed.
Chinese authorities maintain that the firm, called Fake Cultural Development, owes them money and it must be paid back.
