Election of Article 15 Service Retirement Based on Non-DOCCS Employment Bars Later § 507-b Performance-of-Duty Disability Retirement

1. Introduction

Matter of Mussaw v DiNapoli (2026 NY Slip Op 04898) is a CPLR article 78 proceeding in which petitioner Charles Mussaw sought judicial review of the State Comptroller’s denial of his application for performance of duty disability retirement under Retirement and Social Security Law (RSSL) article 14, § 507-b. The respondent, Comptroller Thomas P. DiNapoli, denied the benefit because petitioner had already retired under RSSL article 15 based on later, non-DOCCS employment (a part-time village job) and therefore was not “a member in the [R]etirement [S]ystem … based on employment as a correction officer” when he retired.

The central issues were: (i) whether the statutes permit a member to pursue an article 14, § 507-b correction-officer disability benefit after having retired under article 15 based on different employment; (ii) whether the Comptroller’s “job title at time of retirement” eligibility rule is a reasonable statutory interpretation supported by substantial evidence; and (iii) whether alleged erroneous advice from public employees could estop the Retirement System from enforcing statutory eligibility limits.

2. Summary of the Opinion

The Third Department confirmed the Comptroller’s determination and dismissed the petition. The Court held that:

  • Eligibility for § 507-b performance of duty disability retirement depends on the member’s qualifying status tied to correction-officer employment; petitioner’s retirement was effectuated under article 15 based on village employment, not DOCCS correction-officer employment.
  • The Comptroller reasonably interprets the RSSL to determine initial eligibility for article 14 vs. article 15 benefits based on the member’s job title at the time of retirement.
  • Statutory provisions that expressly allow “simultaneous” filings (service retirement filed “without prejudice” to disability) underscore that the Legislature knows how to authorize dual-track applications; § 507-b contains no comparable authorization for petitioner’s post-retirement, post-article-15 election scenario.
  • Estoppel cannot create retirement benefit eligibility where the statute does not allow it, even if erroneous advice was given.

3. Analysis

A. Precedents Cited

Matter of Laurino v DiNapoli

The Court invoked Matter of Laurino v DiNapoli to explain the purpose of § 507-b: it is aimed at compensating correction officers who become permanently disabled due to the particular risks of their institutional duties. This purpose supports a narrow, status-based reading—i.e., the benefit is tethered to being a correction officer in covered service, not merely having once been one.

Matter of Roberts v Murphy and Lynch v City of New York

Matter of Roberts v Murphy framed article 15 as a “comprehensive scheme” for service retirement for eligible members (including village employees) who meet age and service requirements. Lynch v City of New York was cited for the proposition that certain uniformed service members are excluded from article 15; the Court used this to rebut petitioner’s suggestion that DOCCS correction officers are not excluded, pointing instead to RSSL § 600 (a) (2) (a) as excluding them. These authorities help ground the Court’s conclusion that moving into an article 15-eligible role entails an election that is structurally inconsistent with retaining article 14 correction-officer status for § 507-b purposes.

Matter of Lurry-Carter v New York State & Local Retirement Sys. and Matter of Gallante v DiNapoli

These cases supplied the administrative-law standard of review in retirement cases: the Comptroller has “exclusive authority” to resolve retirement applications; the agency’s interpretation is upheld if reasonable, and factual findings must be supported by substantial evidence. Matter of Gallante v DiNapoli further exemplifies deference to the Comptroller in retirement determinations.

Matter of Walsh v New York State Comptroller and Matter of Strzepek v DiNapoli

These authorities provided the Court’s interpretive methodology: ascertain and give effect to legislative intent. Matter of Strzepek v DiNapoli also appears in the footnote discussion of “pension maximization” job transitions, reinforcing that the Court is addressing a recurring practical pattern.

Matter of Earle v Office of the N.Y. State Comptroller

Matter of Earle v Office of the N.Y. State Comptroller was central: it supports the Comptroller’s consistent approach of using the member’s job title at retirement to decide whether the member is in an article 14 track or an article 15 track. The Court relied on this precedent both to validate the rule’s reasonableness and to show it is not ad hoc as applied to petitioner.

Matter of Radwan v DiNapoli (and footnote references including Matter of Vladyka v DiNapoli and Matter of Ballard v DiNapoli)

The Court used Matter of Radwan v DiNapoli for the no-estoppel principle in statutory benefit eligibility: incorrect advice cannot expand eligibility beyond what the statute permits. The footnote’s citations—Matter of Vladyka v DiNapoli, Matter of Radwan v DiNapoli, and Matter of Strzepek v DiNapoli— situate this case within a broader pattern of members changing job titles near retirement to seek more favorable benefit structures.

Matter of Ballard v DiNapoli is used to demonstrate “consistency” in the Comptroller’s administration: if article 15 employment is not bona fide, the Comptroller may deny article 15 benefits and instead grant article 14 benefits because the “final legitimate job title” remains correction officer. This comparison sharpened the Court’s key factual pivot in Mussaw: petitioner’s final job was legitimately the village position, so the rule cuts against him.

B. Legal Reasoning

  1. Text and purpose of § 507-b: The Court started from § 507-b’s scope—benefits for members in DOCCS uniformed institutional service incapacitated as the natural and proximate result of a duty injury—and reinforced its correction-officer-protection purpose through Matter of Laurino v DiNapoli.
  2. Structural incompatibility of article 15 election with DOCCS correction-officer status: Relying on agency testimony, the Court accepted that petitioner had to “give up” his DOCCS correction-officer membership status to be eligible for article 15 benefits (given exclusion rules such as RSSL § 600 [a] [2] [a]). Once petitioner elected article 15 retirement based on village employment, he “necessarily became ineligible” for article 14 benefits, including § 507-b.
  3. Legislative design regarding simultaneous applications: The Court found it significant that the RSSL expressly authorizes “simultaneous” service and disability filings in specified provisions—so long as the service retirement is filed “without prejudice” to the disability application (e.g., RSSL § 63 [f] and related sections cited). The absence of a similar “without prejudice” mechanism in § 507-b for a member who has already retired under article 15 based on different employment suggested that the Legislature did not intend the pathway petitioner claimed.
  4. Timing and procedure: Even assuming arguendo that a simultaneous filing concept could apply, petitioner did not file in that manner: he applied for § 507-b roughly two years after his article 15 retirement took effect, and his service retirement application did not indicate it was “without prejudice.”
  5. Administrative deference and evidentiary support: Under the cited standards (Matter of Lurry-Carter v New York State & Local Retirement Sys.), the Court upheld the Comptroller’s interpretation as reasonable and found substantial evidence because there was no dispute that petitioner’s final employment at retirement was with the Village, not DOCCS.
  6. No estoppel: Finally, the Court applied Matter of Radwan v DiNapoli to reject petitioner’s reliance on alleged bad advice; statutory eligibility cannot be created by erroneous administrative guidance.

C. Impact

The decision reinforces a clear, administrable rule for New York public retirement disputes involving job changes near retirement: eligibility for article 14 correction-officer disability benefits under § 507-b is tied to the member’s qualifying correction-officer status at the time of retirement, and an article 15 service-retirement election based on non-DOCCS employment forecloses later § 507-b claims absent explicit statutory authorization.

Practically, the Opinion signals that members pursuing “pension maximization” through late-career transitions must address disability contingencies before finalizing an article 15 retirement, and, where permitted by statute, must follow any “without prejudice” simultaneous-filing procedures. For administrators and litigants, it also strengthens the Comptroller’s reliance on a consistent “final job title at retirement” framework, while narrowing arguments that would treat later disability filings as independent of the retirement election actually made.

4. Complex Concepts Simplified

  • “Performance of duty disability retirement” (§ 507-b): A disability pension specifically for covered DOCCS uniformed personnel whose disabling condition is caused by a duty-related injury or similar covered event.
  • Article 14 vs. Article 15: Article 14 generally covers certain uniformed/hazardous duty categories with specialized benefits; article 15 is a general service retirement plan for eligible public employees (including certain municipal employees). Some groups (including DOCCS correction officers, per the Court’s reading of RSSL § 600 [a] [2] [a]) are excluded from article 15.
  • “Simultaneous application” / “without prejudice”: Some RSSL provisions allow a person to apply for ordinary service retirement while also applying for disability retirement—so the service retirement does not waive the disability claim. This usually must be stated and filed in the manner the statute prescribes.
  • “Substantial evidence” (in an article 78 context): A deferential evidentiary standard—whether the agency’s finding is supported by such relevant proof as a reasonable mind may accept; not whether the court would decide the facts differently.
  • Estoppel against the government (in pension cases): Generally unavailable to grant benefits the statute does not permit, even if an employee gave incorrect guidance.

5. Conclusion

Matter of Mussaw v DiNapoli confirms that a member who retires under RSSL article 15 based on non-DOCCS employment cannot later obtain § 507-b performance of duty disability retirement tied to DOCCS correction-officer service, absent clear statutory authorization and compliance with any required “without prejudice” procedures. The Opinion strengthens doctrinal continuity in Third Department retirement jurisprudence by (i) deferring to the Comptroller’s reasonable, consistently applied “job title at time of retirement” eligibility rule, (ii) reading the RSSL as a structured set of elections with specific, express pathways for dual filings, and (iii) reaffirming that erroneous advice cannot expand statutory pension eligibility.
