Permit Modifications Dependent on Annulled Mining Permits Are Legal Nullities and Need No UPA Revocation

1. Introduction

Matter of Sand Land Corp. v. New York State Dept. of Envtl. Conservation (Appellate Division, Third Department, Apr. 2, 2026) addresses what happens when an agency issues a later “permit modification” that expressly bases ongoing mining authority on earlier permits that are subsequently judicially annulled. The dispute arose from a long-operating sand and gravel mine in the Town of Southampton, Suffolk County, where mining is generally prohibited by zoning.

The central issues were: (i) whether DEC’s May 2020 permit modification survived the judicial annulment of the June 2019 modification and March 2019 renewal permits, and (ii) whether the May 2020 modification needed to be formally suspended or revoked under the Uniform Procedures Act before DEC could treat it as ineffective. Petitioners (Sand Land and related parties) sought a declaration that the 2020 modification remained controlling unless revoked through proper process; DEC and intervenors contended it was a nullity once the 2019 permits were annulled.

2. Summary of the Opinion

The Third Department affirmed Supreme Court’s declaration that the operative authorization during the relevant period was the 2013 renewal permit, as modified by the 2016 order on consent (which, among other things, incorporated the “stump dump” area within the life of mine).

The court held that the May 2020 modification did not independently grant mining authority. Because it expressly stated that “[a]ll mining activities” would continue in accordance with the June 5, 2019 modification, it “derived entirely” from permits that were later annulled. Once those 2019 permits were treated as legal nullities (or, at minimum, ceased to exist upon annulment), the 2020 modification could not stand on its own. No separate UPA suspension/revocation process was required because the 2020 modification failed automatically as a legal consequence of the judicial annulment of its sole foundation.

The court declined to reach DEC’s judicial estoppel argument as an alternative ground, but noted petitioners’ present position conflicted with positions advanced in related litigation.

3. Analysis

3.1. Precedents Cited

Core mining-permit framework and the prior nonconforming use condition

  • Matter of Town of Southampton v New York State Dept. of Envtl. Conservation, 194 AD3d 1310 (3d Dept 2021), mod 39 NY3d 201 (2023)
    This earlier litigation involved the same mine and the same statutory barrier in covered counties: ECL 23-2703 (3), which prevents DEC from considering mining permits where local zoning prohibits mining “within the area proposed to be mined.” The Third Department had annulled the 2019 permits on the view that ECL 23-2703 (3) applied to renewals and modifications. That annulment set the stage for the “what remains operative?” question presented here.
  • Matter of Town of Southampton v New York State Dept. of Envtl. Conservation, 39 NY3d 201 (2023)
    The Court of Appeals affirmed annulment but clarified the governing principle: DEC may process renewal and modification applications in covered counties if the proposed mining falls within an undisputed prior nonconforming use, because in that circumstance the mining is not “actually prohibited” by zoning. Crucially, because the scope of Sand Land’s nonconforming use had not been established, the Court of Appeals required a remand to DEC to determine that scope. The Third Department in 2026 treats this as imposing a statutory “condition precedent” to DEC’s authority to grant the 2019 permits.

Void/voidable administrative action and the effect of annulment

  • Faison v Lewis, 25 NY3d 220 (2015)
    Cited for the proposition that actions taken in excess of authority can be treated as nullities. The Third Department uses it to support characterizing the 2019 permits as void where DEC lacked power to issue them absent the required nonconforming-use determination.
  • Matter of Cobleskill Stone Prods., Inc. v Town of Schoharie, 169 AD3d 1182 (3d Dept 2019)
    Reinforces that governmental actions taken beyond lawful authority may be treated as legal nullities. It supports the court’s conclusion that an unsatisfied statutory prerequisite can deprive an agency of power such that resulting approvals are not merely erroneous but ultra vires.
  • Matter of Socha v Town of Starkey, 239 AD3d 1298 (4th Dept 2025) and Matter of Reiss v Keator, 150 AD2d 939 (3d Dept 1989)
    Both are cited as additional support for treating ultra vires governmental acts as nullities. They serve a reinforcing role: even across departments and over time, New York courts recognize that some defects go to power, not discretion.
  • Matter of Village of Hudson Falls v New York State Dept. of Envtl. Conservation, 158 AD2d 24 (3d Dept 1990), affd 77 NY2d 983 (1991)
    Used for the key downstream proposition: even if a permit were viewed as “voidable,” once judicially annulled it “ceased to exist” and cannot serve as a predicate for later agency action that depends on it. This is the doctrinal bridge that defeats petitioners’ fallback argument that the 2019 permits were merely voidable and thus could have supported the 2020 modification until revoked.

Judicial estoppel (not reached, but discussed)

  • 12 New St., LLC v National Wine & Spirits, Inc., 196 AD3d 883 (3d Dept 2021)
    Cited generally as a reference point for judicial estoppel principles. The Third Department ultimately did not decide the appeal on estoppel grounds, but invoked the doctrine to underscore the equitable concern raised by petitioners’ changed positions across related proceedings.
  • Huizhi Liu v Guoqing Guan, 225 AD3d 749 (2d Dept 2024) and White Rock Ins. Co. PCC Ltd. v Lloyd's Syndicate 4242, 202 AD3d 563 (1st Dept 2022)
    These cases are used illustratively to compare when a party’s shift in position is more than a “refinement” and implicates the integrity concerns that judicial estoppel addresses.

3.2. Legal Reasoning

  1. The 2020 modification was derivative by its own terms.
    The decisive textual fact is that the May 2020 modification expressly provided that “[a]ll mining activities at the site” would continue “in accordance with the permit modification issued on 6/5/2019.” The court reads this as a complete dependency: the 2020 modification did not separately re-authorize mining, it merely adjusted certain conditions while presupposing the June 2019 mining authorization as the operative grant.
  2. DEC lacked authority to issue the 2019 permits absent the required nonconforming-use determination.
    Applying Matter of Town of Southampton v New York State Dept. of Envtl. Conservation, 39 NY3d 201 (2023), the court treats the establishment of a lawful prior nonconforming use (covering the proposed mining area) as a statutory prerequisite to DEC’s authority in a covered county under ECL 23-2703 (3). Because that prerequisite was not satisfied, the 2019 permits were issued “in excess of the agency’s power.”
  3. Ultra vires permits are legal nullities; even if merely voidable, annulment ends them.
    The court holds the 2019 permits were properly treated as legal nullities, relying on Faison v Lewis, Matter of Cobleskill Stone Prods., Inc. v Town of Schoharie, Matter of Socha v Town of Starkey, and Matter of Reiss v Keator. Then, in the alternative, it reasons that even if the 2019 permits were only voidable, once judicially annulled they “ceased to exist” (Matter of Village of Hudson Falls v New York State Dept. of Envtl. Conservation), and thus could not serve as a legal foundation for the 2020 modification.
  4. No UPA suspension or revocation procedure was required.
    Petitioners argued DEC had to formally suspend or revoke the 2020 modification under UPA procedures (citing, as the court does, ECL 70-0115 (1) and 6 NYCRR 621.13 (c)). The court rejects that framing: UPA procedures govern agency-initiated modification, suspension, or revocation of an existing permit. Here, the 2020 modification fell away automatically as the legal consequence of a judicial annulment of the only permits that authorized “all mining activities” it purported to continue.
  5. Mootness was rejected because the permit’s status could have continuing legal consequences.
    Although DEC argued the appeal was moot because the 2020 permit expired in March 2024, the court held the record did not show the permit’s status could have no continuing legal consequences (including for future permitting), and therefore it declined to dismiss as moot.

3.3. Impact

  • Drafting and dependency risk in permit modifications.
    The decision highlights a practical vulnerability: where a modification instrument explicitly “continues” operations solely “in accordance with” an underlying permit, it may collapse if that underlying permit is annulled. Agencies and applicants may respond by ensuring that later permits contain independent grants of authority (where lawful), or at least severability-like structuring so conditions can survive if a predicate approval fails.
  • Clarifies the remedial consequence of annulment in permitting chains.
    The opinion confirms that judicial annulment can have immediate, automatic effects on downstream actions that are expressly derivative—without requiring additional administrative steps—thereby accelerating enforcement clarity and limiting arguments that an agency must separately revoke what has already lost its legal footing.
  • Strengthens the “condition precedent” reading of ECL 23-2703 (3) post-2023.
    Building on the Court of Appeals’ remand logic, the Third Department frames the nonconforming-use determination as a prerequisite to DEC’s authority in covered counties. That characterization will likely be invoked in future disputes about whether DEC’s actions were merely erroneous (voidable) or beyond power (void).
  • Litigation-position consistency and estoppel pressure.
    While not dispositive here, the court’s discussion signals that parties who take one view of “what permit governs” in one proceeding and the opposite in another should expect judicial estoppel arguments to be taken seriously, especially when the earlier position produced a litigation advantage.

4. Complex Concepts Simplified

Prior nonconforming use
A land use that lawfully existed before a zoning change and may continue despite the new prohibition. Here, the Court of Appeals held DEC may process certain mining permit actions in a zoning-prohibited area if the mining sought is within the scope of that lawful preexisting use—meaning the use is not “actually prohibited” as applied to that property.
Condition precedent to agency authority
A fact or determination that must exist before an agency has legal power to act. The Third Department treated the establishment of the scope of the lawful nonconforming use as a prerequisite to DEC’s authority to grant the 2019 permits in a covered county under ECL 23-2703 (3).
Void vs. voidable; “legal nullity”
“Void” (often used when an agency lacked power) means the act is treated as having no legal effect; “voidable” means it has effect unless and until invalidated. The court held the 2019 permits were properly treated as nullities because issued in excess of authority; but it also held that even if merely voidable, judicial annulment ends their existence, preventing reliance on them as a predicate thereafter.
Uniform Procedures Act (UPA) suspension/revocation process
Statutory and regulatory procedures governing when an agency modifies, suspends, or revokes an existing permit (see ECL 70-0115 [1]; 6 NYCRR 621.13 [c]). The court held those procedures do not apply when a permit’s ineffectiveness follows automatically from a court’s annulment of its legal foundation.

5. Conclusion

Matter of Sand Land Corp. v. New York State Dept. of Envtl. Conservation establishes a clear rule for “permit chains” in New York environmental and land-use permitting: when a later permit modification explicitly depends on earlier permits for the continuation of “all mining activities,” and those earlier permits are judicially annulled as ultra vires (or otherwise cease to exist upon annulment), the later modification is ineffective as a matter of law—without the need for a separate UPA suspension or revocation proceeding. The decision reinforces the post-2023 landscape in covered counties under ECL 23-2703 (3): absent a determination that proposed mining falls within the scope of a lawful prior nonconforming use, DEC’s permitting authority is not triggered, and downstream reliance on such permits is precarious.
