(concurring):
I concur in parts (1) — (7) of the court’s opinion, and in the result of part (8). The issue addressed in part (8) is whether evidence must be admitted when its only relevance is to enable a jury to decide whether to exercise its nullification power.1 In my opinion, the record in this case is plainly inadequate for deciding that issue.
*1099Appellant’s entire claim is based on the trial court’s denial of a codefendant’s request that Judge Bryant be subpoenaed to testify. (Tr. 1649) The codefendant made no proffer of evidence, nor did he explain the reasons for requesting the subpoena. The appellants gave no indication that they joined in the request. Most important, none of the defendants objected to the trial judge’s ruling after he explained that he had spoken to Judge Bryant and had been informed by Judge Bryant that his order of October 13 was not intended to bar prosecution.
Since there was neither a proffer nor an objection, the only question properly before us is whether the refusal to grant the subpoena — or admit the evidence— constitutes plain error, “affecting substantial rights.” 2 Since we cannot place the trial court’s decision within that category, I join in affirmance.
. That issue was not decided in United States v. Dougherty, 154 U.S.App.D.C. 76, 473 F.2d 1113 (1972), which holds only “that a trial judge need not deliver an instruction explaining the process of jury nullification.” (173 U.S.App.D.C. page -, 523 F.2d page 1098, supra)
