Plea bargain
In China, a plea bargaining pilot scheme has been introduced by the Standing Committee of the National People's Congress in 2016. For defendants that faces jail terms of three years or below, agrees to plea guilty voluntarily and agree with prosecutors' crime and sentencing proposals, will be given mitigated punishments.
United States constitutional criminal procedure
The government is not required to disclose impeachment material prior to plea bargaining. Whether the government must disclose exculpatory material during plea bargaining is an open question."It has long been accepted that a person whose mental condition is such that he lacks the capacity to understand the nature and object of the proceedings against him, to consult with counsel, and to assist in preparing his defense may not be subjected to a trial" consistent with the Due Process Clause. The "test" is "whether he has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding—and whether he has a rational as well as factual understanding of the proceedings against him."
