§ 63. Accidental disability retirement. a. A member shall be entitled to an accidental disability retirement allowance if, at the time application therefor is filed, he is: 1. Physically or mentally incapacitated for performance of duty as the natural and proximate result of an accident not caused by his own willful negligence sustained in such service and while actually a member of the retirement system, and 2. Actually in service upon which his membership is based. However, in a case where a member is discontinued from service subsequent to the accident, either voluntarily or involuntarily, and provided that the member meets the requirements of paragraph one of this subdivision, application may be made either (a) by a vested member incapacitated as the result of a qualifying World Trade Center condition as defined in section two of this article at any time, or (b) not later than two years after the member is first discontinued from service. b. Application for an accidental disability retirement allowance for such a member may be made by: 1. Such member, or 2. The head of the department in which such member is employed, or 3. Some person acting on behalf of and authorized by such member. c. (a) After the filing of such an application such member shall be given one or more medical examinations. No such application shall be approved, however, unless the member or some other person on his behalf shall have filed written notice in the office of the comptroller within ninety days after the accident, setting forth: 1. The time when and the place where such accident occurred, and 2. The particulars thereof, and 3. The nature and extent of the member's injuries, and 4. His alleged incapacity.

(b) The notice herein required need not be given: 1. If notice of such accident shall be filed in accordance with the provisions of the workers' compensation law of any state within which a participating employer shall have its employees located or performing functions and duties within the normal scope of their employment, or 2. If the application for accidental disability retirement is filed within one year after the date of such accident, or 3. If a failure to file notice has been excused for good cause shown as provided by rules and regulations promulgated by the comptroller. d. If the comptroller determines that the member is physically or mentally incapacitated for the performance of duty and ought to be retired for accidental disability, such member shall be so retired. Such retirement shall be effective as of a date approved by the comptroller. e. The retirement allowance payable upon accidental disability retirement shall consist of: 1. An annuity which shall be the actuarial equivalent of the member's accumulated contributions, plus 2. A pension which is the actuarial equivalent of the reserve-for-increased-take-home-pay to which he may be entitled, if any, plus 3. A pension of three-quarters of his final average salary. The payment of such pension shall be subject to the provisions of section sixty-four of this article. f. If the member, at the time of the filing of an application under the provisions of subdivision b hereof, is eligible for a service retirement benefit, then and in that event, he may simultaneously file an application for service retirement in accordance with the provisions of section seventy of this chapter, provided that the member indicates on the application for service retirement that such application is filed without prejudice to the application for accidental disability retirement. g. 1. (a) Notwithstanding any provisions of this chapter or of any general, special or local law, charter, administrative code or rule or regulation to the contrary, if any condition or impairment of health is caused by a qualifying World Trade Center condition as defined in section two of this article, it shall be presumptive evidence that it was incurred in the performance and discharge of duty and the natural and proximate result of an accident not caused by such member's own willful negligence, unless the contrary be proved by competent evidence.

(b) The comptroller is hereby authorized to promulgate rules and regulations to implement the provisions of this paragraph. 2. (a) Notwithstanding the provisions of this chapter or of any general, special or local law, charter, administrative code or rule or regulation to the contrary, if a member who participated in World Trade Center rescue, recovery or cleanup operations, as defined in section two of this article, and subsequently retired on a service retirement, an ordinary disability retirement or a performance of duty disability retirement and subsequent to such retirement is determined by the comptroller to have a qualifying World Trade Center condition, as defined in section two of this article, upon such determination by the comptroller it shall be presumed that such disability was incurred in the performance and discharge of duty as the natural and proximate result of an accident not caused by such member's own willful negligence, and that the member would have been physically or mentally incapacitated for the performance and discharge of duty of the position from which he or she retired had the condition been known and fully developed at the time of the member's retirement, unless the contrary is proven by competent evidence.

(b) The comptroller shall consider a reclassification of the member's retirement as an accidental disability retirement effective as of the date of such reclassification.

(c) Such member's retirement option shall not be changed as a result of such reclassification.

(d) The member's former employer at the time of the member's retirement shall have an opportunity to be heard on the member's application for reclassification by the comptroller according to procedures developed by the comptroller.

(e) The comptroller is hereby authorized to promulgate rules and regulations to implement the provisions of this paragraph. h. Notwithstanding any other provision of this chapter or of any general, special or local law, charter, administrative code or rule or regulation to the contrary, if a retiree who: (1) has met the criteria of subdivision g of this section and retired on a service or disability retirement, or would have met the criteria if not already retired on an accidental disability; and (2) has not been retired for more than twenty-five years; and (3) dies from a qualifying World Trade Center condition, as defined in section two of this article, as determined by the applicable head of the retirement system or applicable medical board, then unless the contrary be proven by competent evidence, such retiree shall be deemed to have died as a natural and proximate result of an accident sustained in the performance of duty and not as a result of willful negligence on his or her part. Such retiree's eligible beneficiary, as set forth in section sixty-one of this title, shall be entitled to an accidental death benefit as provided by section sixty-one of this title, however, for the purposes of determining the salary base upon which the accidental death benefit is calculated, the retiree shall be deemed to have died on the date of his or her retirement. Upon the retiree's death, the eligible beneficiary shall make a written application to the head of the retirement system within the time for filing an application for an accidental death benefit as set forth in section sixty-one of this title requesting conversion of such retiree's service or disability retirement benefit to an accidental death benefit. At the time of such conversion, the eligible beneficiary shall relinquish all rights to the prospective benefits payable under the service or disability retirement benefit, including any post-retirement death benefits, since the retiree's death. If the eligible beneficiary is not the only beneficiary receiving or entitled to receive a benefit under the service or disability retirement benefit (including, but not limited to, post-retirement death benefits or benefits paid or payable pursuant to the retiree's option selection), the accidental death benefit payments to the eligible beneficiary will be reduced by any amounts paid or payable to any other beneficiary. i. Notwithstanding any other provision of this chapter or of any general, special or local law, charter, administrative code or rule or regulation to the contrary, if a member who: (1) has met the criteria of subdivision g of this section; and (2) dies in active service from a qualifying World Trade Center condition, as defined in section two of this article, as determined by the applicable head of the retirement system or applicable medical board to have been caused by such member's participation in the World Trade Center rescue, recovery or cleanup operations, as defined in section two of this article, then unless the contrary be proven by competent evidence, such member shall be deemed to have died as a natural and proximate result of an accident sustained in the performance of duty and not as a result of willful negligence on his or her part. Such member's eligible beneficiary, as set forth in section sixty-one of this title, shall be entitled to an accidental death benefit provided he or she makes written application to the head of the retirement system within the time for filing an application for an accidental death benefit as set forth in section sixty-one of this title.
