(a) Transmittal. The foreperson must transmit all physical evidence, including records, presented to or considered by a state grand jury to the superior court clerk of the county in which the assignment judge is serving. The clerk must preserve the evidence and make it available in the same manner as a transcript of grand jury proceedings.

(b) Release or Retention. Nothing in this rule is intended to abrogate any right of a person under applicable law to possess or regain custody of physical evidence, but the assignment judge may impose limitations on access, use, transport, care, and disposal as may be necessary to ensure that the evidence is preserved.
