As to our personal attendance at Richmond, I am persuaded the Court is sensible, that paramount duties to the nation at large control the obligation of compliance with their summons in this case; as they would, should we receive a similar one, to attend the trials of Blannerhassett and others, in the Mississippi territory, those instituted at St. Louis and other places on the western waters, or at any place, other than the seat of government. To comply with such calls would leave the nation without an executive branch, whose agency, nevertheless, is understood to be so constantly necessary, that it is the sole branch which the constitution requires to be always in function. It could not then mean that it should be withdrawn from its station by any co-ordinate authority. With respect to papers, there is certainly a public and a private side to our offices. To the former belong grants of land, patents for inventions, certain commissions, proclamations, and other papers patent in their nature. To the other belong mere executive proceedings. All nations have found it necessary, that for the advantageous conduct of their affairs, some of these proceedings, at least, should remain known to their executive functionary only. He, of course, from the nature of the case, must be the sole judge of which of them the public interests will permit publication. Hence, under our Constitution, in requests of papers from the legislative to the executive branch, an exception is carefully expressed, as to those which he may deem the public welfare may require not to be disclosed; as you will see in the enclosed resolution of the House of Representatives, which produced the message of January 22d, respecting this case. The respect mutually due between the constituted authorities, in their official intercourse, as well as sincere dispositions to do for every one what is just, will always insure from the executive, in exercising the duty of discrimination confided to him, the same candor and integrity to which the nation has in like manner trusted in the disposal of its judiciary authorities. Considering you as the organ for communicating these sentiments to the Court, I address them to you for that purpose, and salute you with esteem and respect. TO GEORGE HAY. WASHINGTON, June 19, 1807.
