James Edward Mercer v. Commonwealth of Virginia
783 S.E.2d 56
Va. Ct. App.2016Background
- Mercer was tried in June 2014 (bench trial) on three counts of distribution of a Schedule I or II controlled substance based on three controlled purchases; the confidential informant and surveillance testified she bought cocaine from Mercer on each occasion.
- Physical samples from each controlled buy were analyzed by DFS; forensic scientist Nancy M. Peace signed each certificate of analysis reporting cocaine. Certificates were admitted at trial without objection; Mercer did not present evidence and was convicted on all three counts.
- Peace was terminated for cause by DFS on August 11, 2014; Mercer (through counsel) was notified of the termination on September 19, 2014, after trial but before sentencing. Peace’s termination letter is not in the record.
- Mercer moved (Oct. 1, 2014) to set aside the verdict / for a new trial, alleging a Brady violation because the Commonwealth failed to disclose Peace’s termination and prior performance issues; he claimed disclosure would have altered trial strategy (object to certificates, call Peace, or request jury trial).
- The Commonwealth responded that it did not know of Peace’s termination until after trial, described DFS’s peer-review quality controls (which had caught Peace’s past false negatives), and noted re-testing of 35 Peace-submitted samples (all confirmed Peace’s originals). The circuit court denied the motion, finding no Brady violation; this appeal follows.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether nondisclosure of the analyst’s termination/performance issues violated Brady (i.e., was favorable, suppressed, and material) | Mercer: Peace’s termination and prior performance issues were favorable/impeaching; had he known, he would have pursued a different trial strategy (object to certificates, call Peace, or demand jury), which could have affected outcome | Commonwealth: It lacked knowledge of Peace’s termination before trial; Peace’s errors were false negatives (not false positives); DFS peer review and subsequent confirmations support reliability, so no suppressed favorable material that would change result | Court affirmed: No Brady violation — the information was not known to Commonwealth before trial and, in any event, the evidence (false negatives) was not favorable or material to Mercer’s guilt and did not undermine confidence in the verdict |
