Rule 1.—­It being essential to the public welfare to maintain in the Executive the exercise of the power of nomination and appointment vested by the Constitution, and thereby to secure that measure of independence and separate responsibility which is contemplated by that instrument; and it being needful, in making such nominations and appointments, that the appointing power should obtain and in the proper Department preserve the evidence of fitness in reference to which all such nominations and appointments should be made:  Therefore recommendations concerning any nomination or appointment to office or place in the civil service can not be considered unless made in writing, signed by the person making them, setting forth the character of the person recommended and his qualifications for the office in reference to which the recommendation is made; nor, when the recommendation is by a person holding an office or station in or under the Government of the United States, can such written recommendation, except when made in response to a written request by the officer making the appointment, or in the discharge of an official duty imposed by the Constitution or the laws, be considered as entitled to any greater weight than if made by such person as a private individual.  But this rule shall not apply to recommendations made by officers as to their own subordinates.

Rule 2.—­While it is not the purpose of the rules and regulations prescribed for the government of the civil service either to restrict the power of removal or to extend the tenure of service, such power will not be exercised arbitrarily, and therefore applications must not be entertained by any authority having the duty of nomination or appointment for the removal of any person in the civil service, nor will any person be removed for the mere purpose of making a place for any other person.

Rule 3.—­To prevent any misapprehension in the public mind in regard to the functions of the members of the Civil Service Commission and of the members of any board of examiners, it is declared not to be any part of the duty or authority of any such member to act upon, take part in, or in any way entertain any recommendation, application, or question concerning appointments or removals in respect of the civil service, otherwise than in the strict discharge of their respective duties as prescribed by the rules and regulations; and for the same purpose it is further declared that the functions of the members of said Commission as to the matters aforesaid extend only to the question of the proper rules and regulations to be made and to supervising their application, and that the functions of the examiners as to said matters extend only to preparing for, conducting, rating, and making reports concerning examinations required to be made under such rules and regulations.
