Del. Code tit. 11 § 8324
Any former, present or future member of the State Highway Police or the State Police, who has heretofore received or who may hereafter receive permanent injuries in the performance of the member's duties, shall upon certification of a physician selected by the Board of Pension Trustees or by the injured person, be entitled to receive a pension equal to one half of the member's salary at the time the injury was received; but no such pension shall be paid as long as such person is regularly employed as a State Police Officer. When, however, a member of the State Police shall desire to retire by reason of injury or disease, the member shall make application in writing to the Board of Pension Trustees for such retirement. Whereupon, the Board of Pension Trustees shall call to its assistance the aid of a physician or surgeon representing the Board of Pension Trustees, and the member may also call to the member's aid a physician or surgeon. Any member of the Board of Pension Trustees may administer oaths to such physician or surgeon or to any other person called as a witness with respect to the matter before the Board of Pension Trustees, and the Board of Pension Trustees shall determine by resolution passed by at least a majority of the members of the Board of Pension Trustees, whether such member is entitled to the benefits of this subchapter, and if so determined, such member shall be retired upon a pension equal to three fourths of the member's salary at the time of retirement, together with cost of medical attention, if such medical attention be made necessary by reason of such injury or disease; provided, however, that members of the State Police who by reason of permanent injuries received in the performance of their duties and who for that reason have retired prior to January 1, 1972, shall as of that date receive an amount equal to three fourths of the monthly salary provided under this chapter for an active duty officer of an equivalent rank in accordance with § 8326 of this title. Thereafter, pensions of State Police retired by reason of permanent injuries received in the performance of their duties shall not be recomputed based on the salaries of active duty State Police; provided further, however, that members of the State Police retired by reason of injury not received in the performance of their duties or disease prior to January 1, 1972, shall as of that date receive an amount equal to one half of the monthly salary provided under this chapter for an active duty officer of equivalent rank in accordance with § 8326 of this title. Thereafter, pensions of State Police members retired by reason of injury or disease shall not be recomputed based on the salaries of active duty State Police; provided further, however, that as of July 1, 1974, the monthly amount payable to State Police retired by reason of permanent injuries received in the performance of their duties and by State Police retired by reason of other injury or disease shall increase on July 1 of each year by any cumulative percentage increase in the national consumer price index average of the previous calendar year, plus the aggregated cumulative percentage change in the national consumer price index average of the previous consecutive years in which an increase was not granted. A cumulative percentage decrease in any calendar year shall not result in any reduction in the pension rates.
Any member who is entitled to a pension equal to three fourths of the member's salary pursuant to this section shall be examined by at least 2 competent physicians employed by the Department of Health and Social Services every 6 months in order to determine the continuing eligibility of said member. Should such pensioner reside without the territorial limits of the State, the pensioner shall submit certificates of examination by 2 competent physicians approved by the Department of Health and Human Services or comparable agency of the state of residence for the foregoing purpose.
