NC Gen Stat 8c-1 Rule 612(B) Interpretation
N.C. Gen. Stat. 8C-1, Rule 612(b) (2007), regulates the disclosure of non-privileged documents to an adverse party:
If, before testifying, a witness uses a writing or object to refresh his memory for the purpose of testifying and the court in its discretion determines that the interests of justice so require, an adverse party is entitled to have those portions of any writing or of the object which relate to the testimony produced, if practicable, at the trial, hearing, or deposition in which the witness is testifying.
Notably, the rule explicitly includes "deposition" testimony.
Moreover, the official Commentary of Rule 612 state that "if the writing is used before testifying for the purpose of testifying, disclosure is in the discretion of the court."
Rule 612(c) addresses the proper procedure when the writing allegedly contains privileged material:
If it is claimed that the writing or object contains privileged information or information not directly related to the subject matter of the testimony, the court shall examine the writing or object in camera, excise any such portions, and order delivery of the remainder to the party entitled thereto. Any portion withheld over objections shall be preserved and made available to the appellate court in the event of an appeal. If a writing or object is not produced, made available for inspection, or delivered pursuant to order under this rule, the court shall make any order justice requires, but in criminal cases if the prosecution elects not to comply, the order shall be one striking the testimony or, if justice so requires, declaring a mistrial.
