Article XXIV
Section 3

Every citizen of the United States who has been a resident of the state of Colorado for such period as the general assembly may determine, who has attained the age of sixty years or more, and who qualifies under the laws of Colorado to receive a pension, shall be entitled to receive the same; provided, however, that no person otherwise qualified shall be denied a pension by reason of the fact that the person is the owner of real estate occupied by the person as a residence; nor for the reason that relatives may be financially able to contribute to the person's support and maintenance; nor shall any person be denied a pension for the reason that the person owns personal property which by law is exempt from execution or attachment; nor shall any person be required, in order to receive a pension, to repay, or promise to repay, the state of Colorado any money paid to the person as an old age pension.
