When the Warrant Was a Lie: The Quiet Power of Commonwealth v. Mallory

A Brockton trafficking and firearms conviction was reversed because police time sheets, obtained through a public records request, proved the search warrant affidavit was false. Read When the Warrant Was a Lie: The Quiet Power of Commonwealth v. Mallory to learn why that matters, and why challenging warrants is often the difference between a conviction and a vacated verdict.

A False Affidavit Exposed: How Time Records Undermined the Warrant

The Massachusetts Appeals Court issued Commonwealth v. Mallory (No. 2) today, and for anyone who practices criminal defense in this Commonwealth, it is the kind of decision you want in your file. It is not a doctrinal revolution. It does not announce a new rule. What it does is harder, and in some ways more valuable: it enforces the rules we already have, and it does so in a case where the defense lawyers kept pushing after the trial was over.

The short version is that police in Brockton obtained a search warrant in 2016 based on three controlled drug purchases by a confidential informant. Officers recovered drugs, a firearm, and ammunition. The defendant was convicted of trafficking in heroin, trafficking in cocaine, and several firearms counts, including enhanced penalties under the Massachusetts armed career criminal act. The third controlled buy, according to the warrant affidavit, was observed by a second detective, identified in the affidavit only by the initial of his first name as “B.” Donahue.

Years after the conviction, the defense obtained the officers’ time sheets through a public records request. The time sheets did not match the affidavit. When the Commonwealth later produced more detailed time records, they confirmed that the only window during which both officers were on duty that day was between 9:13 A.M. and 1:07 P.M., and the defendant’s cell phone records, which trial counsel had pulled before trial, showed no calls during that window. The third buy, as described in the warrant affidavit, could not have happened.

The trial judge, after an evidentiary hearing, found that the sworn statements in the affidavit were false, and that the falsity was at a minimum reckless.

That finding, on its own, would have been remarkable. The Appeals Court affirmed it without difficulty. What makes the opinion important is what came next.

Staleness Is a Living Doctrine

Once the false statements about the third controlled buy were excised from the affidavit, what remained were two controlled purchases, nine days apart, and the last one had occurred twenty days before the search. The Commonwealth argued that the defendant was engaged in a continuous criminal operation, and that the ongoing nature of the activity kept probable cause fresh.

The Appeals Court was not persuaded. Relying on Commonwealth v. Pina, Commonwealth v. Malone, and Commonwealth v. Reddington, the panel reaffirmed a principle that gets quietly lost in practice: probable cause must exist not only at the moment a warrant is issued but also at the moment it is executed. Compliance with the seven-day rule in G.L. c. 276, section 3A does not cure the problem. Two isolated controlled buys, nine days apart, do not establish the kind of protracted, ongoing operation that saves a stale warrant.

CASE AT A GLANCE

Two controlled buys, nine days apart. A third buy that did not happen as sworn. Twenty days between the last verifiable event and the search. That was enough to render the warrant stale once the falsehoods were stripped out.

This matters beyond the four corners of Mallory. Staleness challenges are underused. Defense lawyers and judges alike often treat the warrant timeline as a pro forma box to check. Mallory (No. 2) is a reminder that the timeline is substantive, that drug cases in particular have a short shelf life, and that a careful reading of the affidavit, tip by tip and date by date, can expose a probable-cause failure that would otherwise pass unnoticed.

Trial counsel was not ineffective. The evidence was still newly discovered.

Perhaps the most practically useful part of the opinion is how the Appeals Court resolved the remedy question. The trial judge had denied the new trial motion on what amounts to a paradox: trial counsel was not ineffective for failing to uncover the false statements, but the defendant had also failed to show the evidence was not reasonably discoverable. If both of those propositions were true, the defendant had no remedy at all.

The Appeals Court fixed the paradox. It agreed that trial counsel was not ineffective. Counsel had pulled the cell phone records, seen that they appeared to corroborate the affidavit, and reasonably concluded there was no Franks issue to pursue. Nothing in the four corners of the affidavit would have flagged the third controlled buy as the one to scrutinize.

But the very reason counsel was not ineffective, namely that a reasonable lawyer would not have been alerted to the falsehoods, is the same reason the evidence qualifies as newly discovered under Commonwealth v. Grace and Commonwealth v. Epps. Evidence is newly discovered when it was unknown to the defendant and counsel, and not reasonably discoverable through reasonable pretrial diligence. The Court was clear:

An exceptionally diligent attorney might have obtained the officers’ time sheets and discovered the false statements before trial, but the standard is whether the evidence was reasonably, not theoretically, discoverable.

That sentence is worth reading twice. The standard for newly discovered evidence is not a counsel of perfection. It does not ask whether some hypothetical attorney with unlimited time and resources could have found the evidence. It asks whether a reasonable attorney, exercising reasonable diligence, would have found it. That distinction, properly deployed, keeps the door open for Franks challenges in cases where the truth about an affidavit only surfaces years after trial.

The Ramirez Remedy

Once the Appeals Court agreed that the evidence was newly discovered and that the warrant was invalid, the remedy followed from Commonwealth v. Ramirez. The warrant is struck down. The evidence seized under it is suppressed. The convictions are vacated and the verdicts are set aside. Mallory reconfirms that Ramirez is not a dead letter. When a post-trial Franks challenge succeeds, and when the Commonwealth cannot make its case without the tainted evidence, the convictions go.

Why This Kind of Work Matters

It is easy to read an opinion like Mallory (No. 2) as a story about a warrant affidavit that turned out to be false. It is really a story about what lawyers do after trial. A direct appeal was pursued. A motion for a new trial was filed. When the first batch of time records did not quite prove the point, the defense pressed for more. An evidentiary hearing was requested and obtained. Supplemental briefing was submitted. And when the trial court got the remedy question wrong, the case went back up to the Appeals Court, which got it right.

None of that happens by accident. It happens because defense lawyers, appellate lawyers, and organizations like the Committee for Public Counsel Services, the New England Innocence Project, and MACDL keep doing the unglamorous work of reading affidavits closely, filing public records requests, and refusing to accept that a conviction is the end of the inquiry.

The Fourth Amendment and Article 14 of the Massachusetts Declaration of Rights are not self-enforcing. They live or die in the gap between what a warrant affidavit says and what actually happened on the street that day. Mallory (No. 2) is a reminder that the gap is real, that it matters, and that the work of finding it is part of what criminal defense lawyers are for.

Practical Takeaways for Defense Counsel

1. Request officer time sheets and duty rosters. Public records requests are free and underused. Time records can corroborate or impeach a warrant affidavit in ways that the four corners of the affidavit never can.
2. Take staleness seriously in drug cases. The clock runs from the last verifiable event to the search, not to the issuance of the warrant. Two isolated buys spread across weeks do not automatically establish continuous criminal activity.
3. Do not treat the seven-day rule as a safe harbor. Compliance with G.L. c. 276, section 3A is necessary but not sufficient. Probable cause must still exist at the moment the warrant is executed.
4. Newly discovered evidence is not defeated by the abstract possibility of earlier discovery. If a reasonable and reasonably diligent attorney would not have uncovered the evidence, it qualifies, even when trial counsel was fully competent.
5. Keep Ramirez in your post-conviction toolkit. A successful post-trial Franks challenge is not a theoretical remedy. It ends in suppression and, where the Commonwealth cannot proceed without the suppressed evidence, in vacated convictions.

Frequently Asked Questions

What is a Franks hearing in Massachusetts?

A Franks hearing is an evidentiary hearing where a defendant challenges the truthfulness of statements in a search warrant affidavit. To get one, the defendant must make a substantial preliminary showing that the affiant knowingly, intentionally, or recklessly included false statements, and that those statements were necessary to the finding of probable cause. If the defendant proves the allegations at the hearing, the false statements are excised from the affidavit and the warrant is re-evaluated without them.

What does it mean for a search warrant to be stale?

Probable cause must exist both when the warrant is issued and when it is executed. If too much time has passed between the last piece of incriminating information and the search, the warrant is stale. For drug cases, courts treat probable cause as diminishing quickly because drugs are consumed and moved. Compliance with the seven-day execution rule in G.L. c. 276, section 3A does not cure staleness.

Can newly discovered evidence support a motion for new trial in Massachusetts?

Yes. Under Commonwealth v. Grace and Commonwealth v. Epps, evidence is newly discovered if it was unknown to the defendant or counsel and not reasonably discoverable through reasonable pretrial diligence. Mallory (No. 2) confirms that evidence invalidating a search warrant qualifies, even when trial counsel was not ineffective for missing it.

What happens if a search warrant is invalidated after trial?

Under Commonwealth v. Ramirez, when a post-trial Franks challenge succeeds and the warrant is invalidated, the evidence seized under the warrant must be suppressed. If the case cannot proceed without that evidence, the convictions are vacated and the verdicts are set aside. That was the outcome in Mallory (No. 2).

How do you challenge a search warrant after a conviction is already final?

The vehicle is a motion for new trial under Mass. R. Crim. P. 30(b), often combined with a request for a Franks evidentiary hearing. The motion can be grounded in ineffective assistance of counsel, newly discovered evidence, or both. Mallory (No. 2) illustrates that these can be alternative theories, and that a defendant can prevail on the newly-discovered-evidence theory even when trial counsel acted reasonably.
