And China's lawyers (including academics) also generally agreed: "in the exercise of their duties are trusted to inform or known matters, lawyers should enjoy the right to refuse to testify.
I personally believe that "confidentiality" is a lawyer in the process of practicing the most basic, the most important professional ethics, the only way to make the lawyers (as a profession) to obtain the trust and respect of the parties.
But unfortunately, our law does not give lawyers "the right to refuse to testify", but in the "Criminal Procedure Law," Article 48 provides: "all know the case, have the obligation to testify."
In response to this situation (in fact, not limited to this, and then, for example, our country's "Criminal Procedure Law" due to lawyers in the investigation stage does not have the right to intervene, resulting in the investigation stage of the suspect's interests are not guaranteed; and suspects do not have a real "refused to provide testimony against their own" rights, and so on and so forth), the lawyer community including Academics are actively suggesting that the relevant legislative authorities to consider revising as soon as possible.
Expect the arrival of the real rule of law!
