The Commissioners shall classify, in accordance with the duties of the Department, all positions in the Police Department of the City. The Commissioners may grade and from time to time may regrade the positions governed by any class in accordance with salaries and duties, to the end that the like salaries shall be paid for like duties. New positions when created shall be classified, graded and filled in accordance with these provisions. Before any new position is created by the head of the Police Department, he shall secure from the Civil Service Commission the proper designation of such position and the title of such position shall correspond with the classification adopted in accordance with the provisions of this section. The Council may recommend amendment or repeal of existing rules and adoption of new rules to said Board. Any classification or grading may be amended or abolished by the Commission, and classes calling for similar qualifications may be consolidated, but persons who have been appointed from any such class shall retain any position lawfully held thereunder, so long as such position is maintained, unless removed or otherwise provided herein. (Amended November 8, 1988)
