It is the intent of this act that the members of the commission shall consist only of those persons whose purpose it will be to recommend for appointment on the supreme court only lawyers or judges of recognized integrity, character, ability and judicial temperament, and whose conduct will conform to the letter and the spirit of the constitutional amendment implemented by this act. The commission shall take cognizance of the fact that the best qualified nominees may be those whom it would be most difficult to persuade to serve. Accordingly the commission shall not limit its consideration to persons who have been suggested by others or to persons who have indicated their willingness to serve. The commission may, if it sees fit to do so, tender nominations to one or more qualified persons, prior to and subject to the formal action of the commission in making its nominations, in order to ascertain whether such person will agree to serve if nominated.
