All applications to the executive director shall be made in writing upon such forms and in such manner as the director may require.
Annuity or refundment.
All applications for annuity and refundment shall be subscribed to before a notary public, or other person having statutory authority of a notary public, who shall affix an acknowledgment or jurat thereto.
Interference with delivery.
In the event the office of the system is closed by executive order, strike, or work stoppage on a normal workday so that there is no mail delivery to the office of the system, any application for an annuity or disability benefit mailed in an envelope having a postmark which indicates the application would have been received at the office of the system on the day on which the office was closed shall, for the purpose of determining when the annuity or disability benefit begins to accrue, be deemed to have been received on the first normal workday the office was closed or the date the application was notarized, whichever is later.
If there is no postmark or if the postal employees are on strike and the application is notarized on or after the date the office was closed or the beginning of the postal employees' strike, the date of notarization shall be used.
