Article 19 Service of additional evidence
If at any time before the commencement of the hearing of an appeal, it appears to the respondent that he will want to adduce at the hearing any evidence additional to that contained, or referred to, in the respondent’s papers, he shall serve a copy of the additional evidence on the appellant’s commanding officer and on the court administration officer.
Where it is not practicable or desirable to make a copy of any evidence to which paragraph (1) applies, the respondent shall instead give notice in writing to the appellant’s commanding officer explaining—
the nature of the evidence, and
details of its whereabouts and the name and address of the person who has custody of it.
On receipt of any additional evidence under paragraph (1) or a notice under paragraph (2), the appellant’s commanding officer shall as soon as reasonably practicable serve it on the appellant.
