Information subject to discovery may be intermingled with privileged material. When the subject of discovery contains a mixture of privileged and nonprivileged material, the ALJ may, in the exercise of sound discretion, permit discovery of the nonprivileged information subject to the conditions necessary to reasonably protect the person for whose benefit the privilege exists. A protective order may be entered, or the ALJ may undertake separate privileged information from discoverable material.
