United States v. Queen Nwoye, 824 F.3d 1129

Background

Queen Nwoye was convicted of conspiracy to extort after testifying she took part only because her then‑boyfriend, Adriane Osuagwu, physically abused and coerced her. The extortion netted nearly $200,000 from Dr. Ikemba Iweala.
At trial Nwoye testified about repeated physical violence, threats to kill her, isolation, financial control, and surveillance, but defense counsel did not present expert testimony on battered woman syndrome (BWS).
The district court refused a requested jury instruction on the affirmative defense of duress, concluding Nwoye failed to show no reasonable alternative to the crime; the jury convicted and the D.C. Circuit affirmed on direct appeal.
After completing her sentence and supervised release, Nwoye filed a coram nobis petition arguing ineffective assistance of counsel for failing to call a BWS expert.
The district court held an evidentiary hearing, heard a BWS expert (Dr. Carole Giunta), and denied relief on prejudice grounds.
The D.C. Circuit majority reversed on prejudice, concluding that (1) BWS expert testimony can be admissible and relevant to duress, (2) Dr. Giunta’s proffered testimony would have supported a duress instruction, and (3) there is a reasonable probability the jury would have had a reasonable doubt. The majority remanded for the district court to decide whether counsel’s performance was constitutionally deficient. Senior Judge Sentelle dissented.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether BWS expert testimony is admissible/relevant to prove duress	BWS testimony explains battered victims’ perceptions and impediments to leaving, thus relevant to both imminence and no‑reasonable‑alternative prongs	Government conceded reliability in general but argued BWS would not change duress analysis here	Majority: BWS expert testimony can be reliable and relevant to duress; admissible if reliable and helpful to jury
Whether Dr. Giunta’s proffered BWS testimony would have been admissible in Nwoye’s trial	Dr. Giunta’s testimony was reliable and plainly relevant given Nwoye’s trial testimony of abuse and control	Government did not dispute reliability of Dr. Giunta’s testimony at coram nobis stage	Held: Dr. Giunta’s testimony would have been admissible and relevant
Whether the proffered BWS testimony would have entitled Nwoye to a duress jury instruction	Expert testimony combined with Nwoye’s testimony would have filled the evidentiary gaps on imminence and lack of reasonable alternatives	Government and earlier panel opinion argued Nwoye had repeated opportunities to contact police or escape, so no duress instruction was warranted	Held: The BWS evidence would have supplied sufficient evidence to warrant a duress instruction
Whether counsel’s failure to present BWS testimony was prejudicial under Strickland	Absence of expert testimony deprived Nwoye of any viable legal route to acquittal; there is a reasonable probability the jury would have had reasonable doubt	District court found no prejudice because record showed opportunities to escape and separation undermined duress; dissent urged deference to factual findings	Held: Majority finds prejudice — reasonable probability of different outcome; remands to determine whether counsel’s performance was constitutionally deficient
