Good news from China's judicial system is rare enough to be worth noticing:
In a landmark ruling with far-reaching implications for survivors of domestic violence, China’s Supreme People’s Court (SPC) has overturned the death sentence of Li Yan (李彦), a 43-year-old woman who killed her husband in November 2010. The case has been sent back to the Sichuan High People’s Court for retrial.
...China’s judiciary has been paying increased attention to domestic violence in recent years. By January 2013, the SPC had created a domestic violence task force to consider the issue of domestic violence in criminal cases. In February 2014, the court held a press conference to announce that domestic violence occurs in one in four Chinese households, and one in 10 homicides are the result of domestic violence.
It's fairly clear from this that China's supreme court wanted the sentence reversed, and eventually got it. China has been executing fewer people in recent years as a matter of policy so this might be as much about that as domestic violence.
I think there may also be a kind of reverse-perverse incentive involved in both the death penalty and domestic violence issues, in that so much of China's justice system is subject to political direction, the judiciary may be more willing to act in areas where it can assert itself.
Anyway, this is where the good news ends.
