Exclusive State Forester Review: Municipal Assessors Lack Power to Terminate Erroneous Forest Land Classifications

1. Introduction

In Campelli v. Mansfield (Supreme Court of Connecticut, officially released July 21, 2026), the court addressed whether a municipal assessor may terminate (“declassify”) a property’s forest land classification for local property-tax purposes after discovering the classification was erroneous from inception because the parcel never met the statutory 25-acre minimum.

The plaintiffs, Mario Campelli and Christine Campelli, owned a Mansfield parcel on Hickory Lane. Mansfield’s assessor approved a forest land classification in 2005 based on a certified forester’s report representing the parcel as a single 25-acre tract. In 2021, the assessor discovered the parcel was actually 22.53 acres. The assessor then attempted to justify continued classification through acreage aggregation with the plaintiffs’ forest-classified land in Tolland, but after the plaintiffs sold a key Tolland parcel, the assessor terminated Mansfield’s forest land classification—triggering a substantial increase in assessed value. The trial court ordered reinstatement; Mansfield appealed.

The central issues were statutory: whether declassification authority exists under General Statutes § 12-504h (sale/transfer or use change), § 12-107d (forest land application/classification process), or § 12-55 (b) (assessor “watchtower” correction authority).

2. Summary of the Opinion

The Supreme Court affirmed the trial court. It held that municipal assessors lack statutory authority to terminate even an erroneous forest land classification on the ground that the parcel does not meet, and never met, the acreage requirements of § 12-107b (2). Challenges to a certified forester’s acreage findings must be pursued through the State Forester review mechanism in § 12-107d (i).

The court also held that the sale of the plaintiffs’ Tolland parcel did not trigger termination under § 12-504h (2) because “such land” refers to the land described in the application for the existing classification—here, the Mansfield Hickory Lane property, which was not sold or transferred.

Finally, the court rejected Mansfield’s reliance on § 12-55 (b), holding the claim foreclosed by Griswold Airport, Inc. v. Madison and reiterating that specific land-classification statutes govern over the general assessment-correction statute.

3. Analysis

3.1. Precedents Cited

Carmel Hollow Associates Ltd. Partnership v. Bethlehem

This was the opinion’s controlling anchor. The court relied on Carmel Hollow Associates Ltd. Partnership v. Bethlehem, 269 Conn. 120 (2004), for the proposition that municipal assessors do not possess unilateral authority to terminate a forest land classification—even where the classification was allegedly unauthorized or based on inaccuracies. In Carmel Hollow, the court emphasized the statutory “shall” directive to assessors and the conservation purpose of the forest land scheme, warning that assessors could be influenced by local fiscal pressures inconsistent with statewide conservation policy.

Campelli applied that same structural logic under the post–P.A. 04-115 scheme: notwithstanding significant amendments, the legislature still did not give assessors a general “error-correction” declassification power; instead, it created an administrative review channel—appeal to the State Forester—specifically aimed at disputes about the certified forester’s findings.

Timber Trails Associates v. New Fairfield

Although not heavily analyzed in the court’s reasoning, the plaintiffs invoked Timber Trails Associates v. New Fairfield, 226 Conn. 407 (1993), as part of the doctrinal lineage limiting assessor discretion in this statutory area. The citation reinforces that Connecticut’s current-use classification statutes have long been treated as a tightly regulated framework where assessor authority must be found in express statutory grants, not inferred powers.

Griswold Airport, Inc. v. Madison

The court treated Griswold Airport, Inc. v. Madison, 289 Conn. 723 (2008), as dispositive on Mansfield’s § 12-55 (b) argument. Griswold Airport held that the assessor’s general duty to “equalize” assessments does not imply authority to remove a special land classification as a preliminary step. The specific termination statute (§ 12-504h) controls. Campelli extends that same reasoning to forest land: the assessor’s “watchtower” function cannot be used to circumvent the specific statutory gates for forest land classification and termination (§§ 12-107d and 12-504h).

Tax-statute interpretive cases: Torrington Water Co. v. Board of Tax Review and Rolling Hills Country Club, Inc. v. Board of Tax Review

The court cited Torrington Water Co. v. Board of Tax Review, 168 Conn. 319 (1975), and Rolling Hills Country Club, Inc. v. Board of Tax Review, 168 Conn. 466 (1975), for the canon that ambiguities in taxing statutes are resolved in favor of the taxpayer. This background principle supported the court’s reluctance to infer an assessor declassification power not clearly expressed, particularly where the consequence would be withdrawal of preferential assessment.

Textual/grammar authorities: Lackman v. McAnulty, L. H.-S. v. N. B., and LaProvidenza v. State Employees' Retirement Commission

To interpret “such land” in § 12-504h (2), the court relied on standard last-antecedent/“such” usage principles as discussed in Lackman v. McAnulty, 324 Conn. 277 (2016), L. H.-S. v. N. B., 341 Conn. 483 (2021), and LaProvidenza v. State Employees' Retirement Commission, 178 Conn. 23 (1979). These cases supplied the linguistic rationale for reading “such land” as referring back to the land described in the relevant application, not to other parcels merely owned by the taxpayer.

Other interpretive and restraint cases: Commissioner of Public Safety v. Freedom of Information Commission, Trinity Christian School v. Commission on Human Rights & Opportunities, Mozzochi v. Glastonbury, and PPC Realty, LLC v. Hartford

The court cited Commissioner of Public Safety v. Freedom of Information Commission, 312 Conn. 513 (2014), to emphasize stare decisis in statutory interpretation: prior judicial constructions inform present meaning unless the legislature clearly changes it.

In declining to “fix” any perceived statutory incongruity, the court invoked institutional-restraint principles from Trinity Christian School v. Commission on Human Rights & Opportunities, 329 Conn. 684 (2018), Mozzochi v. Glastonbury, 188 Conn. 276 (1982), and PPC Realty, LLC v. Hartford, 350 Conn. 347 (2024): courts apply the statute as written; policy gaps are for the legislature.

Trial-level reference: Imperial Development, LLC v. Coventry

The court cited Imperial Development, LLC v. Coventry (Super. Ct. 2016) to confirm that the current version of § 12-107d (f) gives assessors a discrete discretionary basis to deny an application only where they determine use has changed prior to assessment—reinforcing that the statute does not otherwise confer broad discretion to deny/undo classifications.

3.2. Legal Reasoning

(a) The court’s reading of § 12-504h: “such land” means the land in the application

The court first disposed of Mansfield’s attempt to use § 12-504h (2) (termination when “such land is sold or transferred”) by applying plain-language grammar: “such land” refers to the land previously specified—i.e., the land described in the application for the existing classification. Because the plaintiffs’ Mansfield application described only the Hickory Lane parcel, and that parcel was not sold or transferred, § 12-504h did not authorize termination.

Importantly, the court emphasized the record point that the Hickory Lane parcel had been classified under § 12-107b (2) (A) as a single 25-acre tract (as represented), “independent of” the Tolland parcel. That factual and procedural framing foreclosed Mansfield’s attempt to treat the later Tolland sale as a sale of “such land.”

(b) § 12-107d after P.A. 04-115: exclusive correction channel is appeal to the State Forester

The harder question was whether the post–P.A. 04-115 version of § 12-107d altered Carmel Hollow enough to permit an assessor to terminate an erroneous classification for noncompliance with acreage requirements.

The court acknowledged P.A. 04-115’s major structural change: shifting evaluation to a certified forester and providing a mechanism by which the municipality (or owner) “may appeal to the State Forester for a review of the findings of the certified forester.” That appeal expressly encompasses disputes over “the total number of acres” satisfying forest land standards.

Against that backdrop, the court drew a key distinction:

  • What assessors may do under § 12-107d (f): deny (or refuse to continue) classification where they determine the use of the land as forest land has changed as of a date at or prior to assessment.
  • What assessors may not do: override the certified forester’s acreage determination—retroactively or prospectively—by declassifying on the basis that the parcel never met the statutory acreage threshold.

The court treated the State Forester review as the exclusive statutory mechanism to correct errors in the certified forester’s acreage findings. Because Mansfield did not pursue that appeal route, the assessor could not accomplish the same result indirectly through local declassification.

(c) § 12-55 (b) cannot be used to revoke a classification governed by specific statutes

Mansfield argued that § 12-55 (b) (“equalize” and “make any assessment omitted by mistake”) permitted the assessor to correct an erroneous forest land classification. Relying on Griswold Airport, the court rejected the argument as an attempt to use a general assessment-power statute to displace a specific classification-and-termination regime. The court treated §§ 12-107d and 12-504h as the governing statutes; because those provisions do not allow assessor termination for “initial error,” § 12-55 (b) was inapplicable.

3.3. Impact

1) Reinforces exclusive administrative review by the State Forester.
Municipalities disputing a certified forester’s acreage calculation must act promptly through § 12-107d (i) and the implementing regulation pathway (e.g., Regs., Conn. State Agencies § 12-107d-4 (f)). A town’s failure to appeal within the statutory window can effectively lock in the classification until a statutory termination event occurs.

2) Limits municipal “self-help” declassification and stabilizes landowners’ reliance interests.
The decision prevents unilateral retroactive correction by assessors (even when the town later discovers an acreage error), protecting the predictability of current-use classifications and the statutory conservation objective.

3) Practical consequence: erroneous classifications may persist absent sale/use change.
The court expressly acknowledged potential incongruity: assessors can terminate upon sale/transfer or use change but not upon discovery of an initial mistake. The court made clear that closing that gap is a legislative task.

4) Clarifies “such land” in § 12-504h (2), constraining cross-parcel theories of termination.
For owners with multiple parcels (including in different towns), termination under § 12-504h turns on whether the parcel(s) described in the relevant application were sold/transferred, not on broader ownership changes elsewhere—unless those other parcels were actually part of the application defining the “existing classification.”

4. Complex Concepts Simplified

  • “Forest land” classification (current-use assessment): A property-tax benefit where qualifying land is assessed based on its present conservation use rather than market value (see § 12-63 (a)), designed to discourage conversion to intensive development.
  • Certified forester vs. State Forester: A certified forester is a trained, certified private professional who evaluates land and issues the qualifying report. The State Forester functions as the statutory reviewer/arbiter when a municipality or owner appeals the certified forester’s findings.
  • “Such land”: A statutory reference word meaning “the aforementioned land”—here, the land identified in the application giving rise to the “existing classification,” not any land the owner happens to own.
  • Assessor’s “watchtower role” under § 12-55 (b): A general duty to correct assessment inequalities and mistakes. After Campelli, that general role does not include the power to revoke a specialized land classification that is governed by more specific statutes.
  • De novo trial in a tax appeal: The Superior Court hears the matter anew rather than merely reviewing the board’s record, but the governing question remains the scope of statutory authority.

5. Conclusion

Campelli v. Mansfield establishes (and reaffirms) a clear rule: a municipal assessor cannot terminate an erroneous forest land classification merely because the parcel does not meet—and never met—the statutory acreage requirements. Disputes over acreage findings in a certified forester’s report must be pursued through the State Forester under § 12-107d (i), and termination for property-tax purposes remains confined to the statutory triggers in § 12-504h (sale/transfer of the classified land or change in use) and the limited assessor discretion in § 12-107d (f) (use change determination).

The opinion’s broader significance lies in its insistence on statutory exclusivity in land-classification governance: where the legislature has created a targeted administrative review process and specific termination triggers, courts will not infer additional municipal powers—leaving any perceived policy gaps to legislative correction.
