46 CFR 502.202: Right of parties to present evidence.

Every party has the right to present its case or defense by oral or documentary evidence, to submit rebuttal evidence, and to conduct such cross-examination as may be required for a full and true disclosure of the facts. The presiding officer, however, has the right and duty to limit the introduction of evidence and the examination and cross-examination of witnesses when, in his or her judgment, such evidence or examination is irrelevant, immaterial, or unduly repetitious. [Rule 202.]
