15 CFR 25.34 - Evidence.
(a) The ALJ shall determine the admissibility of evidence.

(c) The ALJ shall exclude irrelevant and inmaterial evidence.
(d) Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or by considerations of undue delay or needless presentation of cumulative evidence.
(e) Although relevant, evidence may be excluded if it is privileged under Federal law.
(f) Evidence concerning offers of compromise or settlement shall be inadmissible to the extent provided in Rule 408 of the Federal Rules of Evidence.
(g) The ALJ shall permit the parties to introduce rebuttal witnesses and evidence.
