But there are other contentions which might be considered more difficult. At his trial, petitioner sought to secure through subpoena duces tecum the longhand notes of the Department's hearing officer, Evensen, as well as his report thereon. Petitioner also claimed at trial the right to inspect the original Federal Bureau of Investigation reports to the Department of Justice. He alleged no specific procedural errors or evidence withheld; nor did he elaborate just what favorable evidence the Federal Bureau of Investigation reports might disclose.

Section 6 (j) of the Act, as we have held, does require the Department's recommendation to be placed in a registrant's file. Gonzales v. United States, supra. But there is nothing in the Act requiring the hearing officer's report to be likewise turned over to the registrant. While the regulations formerly required that the hearing officer's report be placed in the registrant's file, this requirement was eliminated in 1952. Moreover, the hearing officer's report is but intradepartmental, is directed to the Attorney General and, of course, is not the recommendation of the Department. It is not essentially different from a memorandum of an attorney in the Department of Justice, of which the Attorney General receives many, and to which he may give his approval or rejection. It is but part of the whole process within the Department that goes into the making of the final recommendation to the appeal board.
