487 Mass. 370
Mass.2021Background
- In 1999 the victim (the defendant's niece) accused her father and his two brothers, including Clifton Caldwell, of raping her as a child; Caldwell was indicted for aggravated rape in 2000 and convicted in 2002.
- A key prosecution witness was a former cellmate who testified that Caldwell confessed in jail; at trial the prosecutor said the witness had not been promised inducements and disclosed only a generic police report noting prior cooperation.
- Defense counsel had asked pretrial for the witness’s criminal record and any promises or inducements but received no detailed disclosure of the prosecutor’s own handwritten note referencing the witness’s prior involvement in a 1985 rape prosecution (Rancourt).
- At a 2018 evidentiary hearing, posttrial production of the prosecutor’s note showed the witness had played a significant role in the Rancourt prosecution and had received an earlier early release; defense argued this was material, exculpatory impeachment evidence that had been withheld.
- The Superior Court denied the new‑trial motion; the Massachusetts Supreme Judicial Court held the prosecutor’s note was exculpatory and its nondisclosure prejudiced the defendant because the witness was critical to the prosecution’s case, and therefore reversed and ordered a new trial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the prosecutor's handwritten note was exculpatory material that should have been disclosed | Commonwealth: note was cumulative or not within the specific requests, not materially exculpatory | Caldwell: the note pointed to the witness's prior cooperation in Rancourt, showing motive to seek favorable treatment and undermining credibility | Note was exculpatory; it could have led to impeachment evidence undermining the witness's credibility |
| Whether nondisclosure of the note was prejudicial enough to require a new trial | Commonwealth: generic police report was produced; additional detail would not have changed outcome | Caldwell: witness was "critical" corroboration; detailed Rancourt facts would have been a real factor in jury deliberations | Nondisclosure was prejudicial under the Tucceri standard (no specific request); new trial required |
| Whether the issue amounted to ineffective assistance of counsel (failure to investigate) | Commonwealth: trial counsel cross‑examined witness about requests for leniency; no deprivation of available defense | Caldwell: counsel was unaware of Rancourt connection and thus could not impeach effectively | Court did not reach ineffective assistance claim because new trial granted on Brady/exculpatory nondisclosure ground |
| Whether the prosecutor's note was within prosecutor's possession/control and thus subject to disclosure | Commonwealth: contested only as to materiality/cumulative nature | Caldwell: note was prosecutor's own notation and plainly in possession | Note undisputedly in prosecutor's possession; disclosure obligation applied |
