In the law of [wex:evidence], certain subject matters are privileged, and can not be inquired into in any way. Such privileged information is not subject to [wex:disclosure] or [wex:discovery] and cannot be asked about in testimony. Usually, privileges exist not because of a fear that information provided will be inaccurate, but because there are public policy reasons the information should not be disclosed.

For more about specific privileges, see [wex:privilege against self-incrimination], [wex:spousal communications privilege] and [wex:attorney-client privilege].
