The method of doing business in a public office is of necessity more elaborate than in a private concern. There is more responsibility for the work done; more subjection to public criticism in small matters; and a stronger obligation to treat every one alike, which means a more strict adherence to precedent. All this entails a complicated machinery that is less needed in private business, where a man can say that if he makes a mistake the loss falls upon himself and is no other person's affair. In a public office, therefore, more writing is done, more things are preserved and recorded, than in a private business, and there are more steps in a single transaction.[183:1] Now although the procedure in the English departments varies somewhat in detail, the general practice is much the same throughout the public service. When a minister wishes to prepare a measure for Parliament, or to make any change in administrative policy, he consults the permanent under-secretary and any other officials especially familiar with the subject; if, indeed, the matter has not been suggested to him by them. He weighs their advice, and states his conclusion to the permanent under-secretary, who in turn gives his directions to the proper subordinates for carrying it into effect. In such a case the procedure is obvious; but by far the greater part of the action in the central offices begins at the other end, and comes from the contact of the government with the public, or from questions that arise in the course of administration. When anything of this kind occurs, whether it be in the form of a despatch, a petition, a complaint, a request for instructions, or a communication of any sort, it is sent by the official charged with the opening of correspondence to the principal, or senior, clerk within whose province it falls. The senior clerk intrusts it to one of the junior first-class clerks in his division. He examines the paper, and unless it is of such a purely routine character that he feels authorised to dispose of it, he affixes to it a minute or memorandum, which gives a history of the matter, the precedents in similar cases, and any other information that may assist his superiors in reaching a decision, commonly adding a suggestion of the course to be pursued. The paper then goes back to the senior clerk, who inspects it, and if the question is of small consequence approves the minute or directs a different disposition, subscribing his initials. If the affair is more weighty, he adds his own comments in the form of a second minute, and transmits the paper to the permanent under-secretary.[184:1] That officer, as the permanent head of the department, gives the final directions,[184:2] and returns the paper, unless the matter is of great importance, or involves a new question of policy, or is likely to give rise to discussion in Parliament, when he submits it to his political chief with a further minute of his own.[184:3]
