114 A.3d 646
D.C.2015Background
- Moore was convicted of armed robbery based largely on the testimony of alleged victim Lorenzo Thomas and some corroborating physical evidence and a recorded call by Moore.
- Thomas gave inconsistent accounts of the source of the ~$1,066 he said was stolen: first saying restaurant earnings, then a tax refund, later gambling wins; credibility was central to the defense.
- Thomas provided his 2010 federal tax return to the prosecutor; it showed a $4,387 refund driven by a $3,050 Earned Income Credit claimed by listing his 12‑year‑old sister as a dependent.
- The prosecutor told defense counsel and the court that she had discussed the dependency claim with Thomas before his grand jury testimony and that there was no agreement about its propriety; the immunity Thomas received did not cover tax fraud.
- Defense sought to cross‑examine Thomas about (1) whether he fraudulently claimed the EIC (to impeach veracity) and (2) what the prosecutor told him about the return (to show bias). The trial court barred all such questioning as confusing and a matter of tax law.
- The D.C. Court of Appeals held the proffered foundation was sufficient, the court abused its discretion in precluding at least the veracity impeachment, and the error was not harmless; convictions reversed and remanded for new trial.
Issues
| Issue | Moore's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether defense made sufficient factual proffer to cross‑examine Thomas about allegedly fraudulent EIC claim | Proffer showed facts (tax return, preparer checklist, Thomas and sister lived with mother, Thomas’s low AGI, mother likely had higher AGI, prosecutor’s concern) creating reasonable suspicion of tax fraud supporting impeachment | Proffer insufficient; connection speculative and would require expert/extrinsic proof and confuse jury | Proffer was adequate; defense entitled to at least limited voir dire/examination — trial court erred in precluding this impeachment |
| Whether defense had sufficient foundation to probe prosecutor‑Thomas discussion to show testimonial bias | Proffer established prosecutor questioned appropriateness of dependency claim before grand jury and immunity did not cover tax fraud; fear of prosecution could bias Thomas | Cross‑examination on bias speculative and would mislead jurors; foundational showing inadequate | Proffer adequate to support limited questioning on bias; trial court erred in barring that line of inquiry (court did not separately resolve harmlessness of bias exclusion) |
| Whether exclusion of proposed cross‑examination was harmless error | Excluding impeachment by tax‑return evidence could have tipped jury toward reasonable doubt given centrality of Thomas’s credibility | Government argued case was strong and other impeachment was available; error harmless | Error in precluding veracity impeachment was not harmless under non‑constitutional harmless‑error standard; convictions reversed and remanded |
