For the past year, the high court of China’s Hebei Province has been telling Zhang Huizhi it will not review the case of her executed son unless she submits a copy of the judgment against him – a document that only the court has and that it refuses to release.

So this week Mrs Zhang and her family tried to escape their legal limbo by petitioning China’s Supreme People’s Court to review the case of Nie Shubin, who was executed for murder in September 1994.

But officials at the Beijing court refused to intervene. “The supreme court would not accept our case materials because we don’t have the judgment,” says his sister, Nie Shuhui.
