People v Whatts: Remand Required When a Requested Mapp Hearing Was Never Ordered or Litigated

1. Introduction

In People v Whatts (2026 NY Slip Op 01925), the Appellate Division, First Department addressed a procedural and jurisdictional problem that arises when a defendant requests a Mapp hearing in an omnibus motion, but the motion court neither grants nor denies it, and the subsequent suppression hearing proceeds on other grounds.

The prosecution alleged that on November 27, 2016, defendant Samuel Whatts and a cohort committed a burglary-robbery during which the victim was killed. After a jury trial, defendant was convicted of multiple counts, including two counts of murder in the second degree, and was sentenced to an aggregate term of 23 years to life. On appeal, defendant raised multiple issues, but the First Department focused on whether property recovered on the day of arrest (including a wallet and cell phones) should be suppressed under the Fourth Amendment—and, more fundamentally, whether that suppression issue had ever been properly litigated.

2. Summary of the Opinion

The First Department held the appeal in abeyance and remanded for a Mapp hearing. The court concluded:

  • The motion court’s written decision granted Payton, Huntley, and Dunaway hearings, denied a Wade hearing, and was silent as to the requested Mapp hearing.
  • Because there was no ruling by the motion court that adversely affected defendant on the Mapp request, the appellate court lacked jurisdiction to affirm the denial on the theory that the motion was facially insufficient.
  • The hearing court erred by effectively deciding the Mapp issue on a record developed in a suppression hearing that did not actually litigate Mapp (even if some testimony incidentally bore on search-and-seizure facts).
  • A remand was necessary to provide a proper evidentiary forum for the Mapp issue.

3. Analysis

3.1. Precedents Cited

People v Mendoza, 82 NY2d 415 (1993)

The People relied on People v Mendoza for the proposition that a court may summarily deny a suppression hearing request where “the face of defendant’s motion” does not present a factual scenario which, if credited, would warrant suppression. In other words, Mendoza supports summary denial when a motion is conclusory or lacks necessary factual allegations.

The First Department did not reject Mendoza as a legal standard; instead, it held that Mendoza could not be used on appeal to supply a rationale that the motion court itself never adopted. Because the motion court did not deny the Mapp request on Mendoza-type insufficiency grounds (indeed, it did not address Mapp at all), the appellate court treated the People’s argument as speculative and jurisdictionally improper to entertain as an affirmance ground.

People v LaFontaine, 92 NY2d 470 (1998)

People v LaFontaine anchored the First Department’s jurisdictional holding. The opinion quoted the principle that an appellate court violates CPL 470.15(1) when it decides an issue that does not involve an error that “adversely affected the appellant” before the lower court.

Applied here, because the motion court did not deny Mapp—and therefore did not “adversely affect” defendant by an identifiable ruling— the First Department concluded it could not affirm on a procedural basis (i.e., as though there had been a summary denial).

People v Gonzalez, 238 AD3d 519 (1st Dept 2025)

The court cited People v Gonzalez as additional First Department authority reflecting the same CPL 470.15(1) constraint: appellate review/affirmance must tie to an actual adverse ruling below, not a post hoc rationale invented on appeal.

People v Giles, 73 NY2d 666 (1989)

The opinion’s remedial choice—remand for a hearing rather than decide the merits—was supported by People v Giles. Giles recognized that the People are entitled to an evidentiary suppression hearing when an error of law “functionally deprives” them of their one opportunity to present their case on the dispositive suppression issue.

The First Department used Giles to explain why it would be improper to decide the Mapp issue on an underdeveloped and misdirected record: because Mapp was not the litigated subject of the suppression hearing, the People had not necessarily had their full and fair opportunity to present targeted evidence and argument on search-and-seizure legality.

People v Havelka, 45 NY2d 636 (1978)

The opinion distinguished People v Havelka, which cautions against remitting for a rehearing where the People already had a full opportunity to present evidence on the dispositive issues and simply failed—i.e., where a remand would amount to an improper “second chance.”

By citing Havelka “cf.”, the First Department signaled that this case falls on the other side of the line: the defect was not that the People tried and failed on a fully litigated Mapp record, but that the suppression process never actually engaged the Mapp question as an issue to be adjudicated.

3.2. Legal Reasoning

The court’s reasoning proceeds in two steps—jurisdiction and fairness/record adequacy.

(A) Jurisdiction: an appellate court cannot affirm on a ground that assumes an adverse ruling that never occurred

The People’s first argument—that silence amounted to a summary denial—invited the Appellate Division to treat the motion court’s omission as if it were a ruling under People v Mendoza. The First Department refused. It relied on the hearing court’s own statement that there was “no indication why” the motion court failed to address Mapp, and held that the motion court’s silence meant there was no adverse ruling for appellate review under CPL 470.15(1), as explained in People v LaFontaine and reinforced by People v Gonzalez.

(B) Merits cannot be decided on a record where the issue was not litigated as such

The People’s second argument urged affirmance on the substance: that the hearing court had “sufficient facts available after the suppression hearing” to deny suppression. The First Department identified the structural defect: the suppression hearing was ordered and conducted on Payton, Huntley, and Dunaway grounds, not Mapp, and the court itself sustained an objection when defense counsel attempted to cross-examine “as to Mapp” because “[t]here was no Mapp.”

Even if some testimony (e.g., whether defendant’s mother “voluntarily handed” property to the detective) was relevant to a Mapp question, the proceeding did not function as a Mapp hearing: the scope of questioning, the parties’ incentives, and the evidentiary presentation were shaped by the issues actually noticed and ordered. Under People v Giles, deciding a dispositive suppression question without giving the People their proper opportunity to present the case on that question is error; and under People v Havelka, the remand is justified precisely because this is not a “second chance” after a full and fair first chance.

3.3. Impact

The decision has practical consequences for suppression litigation in New York:

  • Motion-court discipline: Trial courts must clearly grant or deny each requested suppression hearing type. Silence can create appellate complications and force remand—even late in a case that has proceeded to trial and conviction.
  • Hearing-scope clarity: When a hearing is ordered on some suppression theories but not others, courts and counsel must be alert that testimony incidentally touching un-ordered theories does not automatically convert the proceeding into a hearing on those theories.
  • Limits on appellate “fixes”: The ruling underscores that appellate courts cannot salvage procedural omissions by deeming them summary denials absent a clear adverse ruling, given CPL 470.15(1) constraints (People v LaFontaine).
  • Remand as a fairness mechanism: Where an unlitigated suppression issue could be dispositive, remand may be required to ensure both sides have a full opportunity to create a record tailored to that issue (People v Giles), while still respecting the no-second-chance principle when a full opportunity has already been afforded (People v Havelka).

4. Complex Concepts Simplified

  • Mapp hearing: A hearing to decide whether physical evidence should be suppressed as the product of an unconstitutional search or seizure (Fourth Amendment). In this case, the disputed items included a wallet and cell phones recovered at arrest.
  • Omnibus motion: A pretrial motion raising multiple requests (e.g., different suppression hearings). Here, defendant requested Payton, Huntley, Dunaway, Wade, and Mapp.
  • Payton hearing: A hearing typically addressing the legality of police entry into a home to make an arrest (often focusing on warrant requirements and consent).
  • Huntley hearing: A hearing on the voluntariness/admissibility of a defendant’s statements to law enforcement.
  • Dunaway hearing: A hearing addressing whether police had probable cause (or sufficient justification) for detention/arrest such that evidence derived from an illegal seizure should be suppressed.
  • Wade hearing: A hearing addressing the admissibility of identification evidence (e.g., lineups, showups).
  • Held in abeyance: The appellate court pauses final resolution of the appeal and sends the case back to the trial court for a specific proceeding—here, a Mapp hearing—after which appellate review can resume with a complete record.
  • CPL 470.15(1) “adversely affected” limitation: The Appellate Division generally reviews errors that harmed the appellant in the lower court; it cannot affirm by inventing a rationale for a ruling the lower court never actually made (People v LaFontaine).

5. Conclusion

People v Whatts establishes a clear procedural safeguard: when a defendant requests a Mapp hearing and the motion court neither grants nor denies it, the issue cannot be resolved on appeal as though it had been summarily denied, nor can it be decided on the merits based on a suppression hearing record where Mapp was not actually litigated. Invoking the jurisdictional constraint of People v LaFontaine and the hearing-opportunity principles of People v Giles (while distinguishing People v Havelka), the First Department remanded for a dedicated Mapp hearing and held the appeal in abeyance—reinforcing that suppression litigation must be decided on properly ordered, properly scoped proceedings, with a record made for the issue being adjudicated.
