An objection must be raised either in writing prior to the prehearing conference provided for in § 156.941 or at the prehearing conference. The ALJ may require a party to submit the original hearing exhibit on his or her own motion or in response to a challenge to the authenticity of a proposed hearing exhibit.(b) A party may introduce a proposed hearing exhibit following the times for submission specified in § 156.937 only if the party establishes to the satisfaction of the ALJ that it could not have produced the exhibit earlier and that the opposing party will not be prejudiced.
