Subd. 1.

The association shall grant pensions payable from the police pension fund in monthly installments, in the manner and for the following purposes:

1. (1) Any member of the age of 50 years or more, who performs duty as a member of the police department of the city for 20 years or more, upon written application after retiring from duty, shall be paid monthly during the retiring member's lifetime a pension equal to 35 units and an additional unit for each year of service in excess of 20 years, but not to exceed 42 units.
2. (2) Any member who performs duty as a member of the police department of the city for 20 years or more who retires from duty before attaining the age of 50 years, upon written application after reaching the age of 50 years shall be paid monthly during the retiring member's lifetime a pension equal to 35 units and an additional unit for each year of service in excess of 20 years, but not to exceed 40 units.
3. (3) Any member who, after ten years service but with less than 20 years service with the police department of the city, becomes superannuated so as to be permanently unable to perform the member's duties, shall be paid monthly during the retiring member's lifetime a pension equal to 16 units and an additional two units for each completed year of service over ten years and less than 20 years.
4. (4) Any member not eligible for a service pension who, while a member of the police department of the city, becomes diseased or sustains an injury which permanently unfits the member for the performance of police duties, shall be paid monthly during the disabled member's lifetime a pension equal to 36 units while so disabled.

Subd. 2.

If a member of the police department of the city is separated from the service under circumstances that no pension benefits are payable to the member or to the member's surviving spouse or to the member's surviving children, the treasurer of the city shall return to the member 75 percent of the amount the member has paid in without interest. In the event the member is reinstated to police duty all moneys paid to the member shall be returned to the pension fund within six months from the date of the reinstatement. Failure to do so relieves the association from any liability as to prior years of service credit as of the reinstatement date. In case of the death of the member, any sums shall be paid to the member's heirs, executors, or administrators.

Subd. 3.

In the case of any applicant for a pension pursuant to subdivision 1, clauses (1), (2), or (3), who, following admission to membership in the association has served in the military forces of the United States in any war or national defense emergency subsequent to January 1, 1940, and thereafter returned honorably discharged from such service and resumed membership in the association, the period that the applicant spent in such military service shall be counted in computing period of service required for benefits under this section. During such period of military service or defense emergency service, any such person is not considered a member of the association and is not entitled to any pension provided by subdivision 1, clauses (3) and (4). If the member does not return to employment in the police department of the city within one year from the time peace is declared or within one year from the termination of the period of emergency, whichever is the later, the provisions of this subdivision shall not apply.

Subd. 4.

No member shall be awarded, granted, or paid a pension pursuant to subdivision 1, clauses (3) and (4), except upon the certificate of two or more physicians or surgeons chosen by the governing board. This certificate shall set forth the cause, nature, and extent of the disability, disease, or injury of the member. No member shall be awarded, granted, or paid a pension pursuant to subdivision 1, clause (4), unless the certificate states the disability, disease, or injury. Each such certificate shall be filed with the association.

Subd. 5.

A member who has been finally convicted of a felony is not entitled to any pension.
