Rule 5-505. Continuing duty to disclose.

A. Additional material or witnesses. If, subsequent to compliance with Rule 5-501 or 5-502, and prior to or during trial, a party discovers additional material or witnesses which he would have been under a duty to produce or disclose at the time of such previous compliance if it were then known to the party, he shall promptly give written notice to the other party or the party's attorney of the existence of the additional material or witnesses. B. Failure to comply. If at any time during the course of the proceedings it is brought to the attention of the court that a party has failed to comply with this rule or with an order issued pursuant to this rule, the court may order such party to permit the discovery or inspection of materials not previously disclosed, grant a continuance, or prohibit the party from calling a witness not disclosed, or introducing in evidence the material not disclosed, or it may enter such other order as it deems appropriate under the circumstances, including but not limited to holding an attorney in contempt of court pursuant to Rule 5-112 of these rules.
