The only real surprise is that they are doing more of this now than they were in the past. BBC News:
The UK-based human rights group Amnesty International has accused China of suppressing lawyers who become involved in politically sensitive cases.
It says many have been threatened with suspension or criminal charges.
If these measures fail, the lawyers can face detention - or even just disappear, it says.
Amnesty says the treatment of lawyers has worsened in recent months, after calls in China for Middle East-style protests.
