Uncodified statutes Only "general and permanent" laws are codified in the United States Code; the Code does not usually include provisions that apply only to a limited number of people (a private law) or for a limited time, such as most appropriation acts or budget laws, which apply only for a single fiscal year. If these limited provisions are significant, however, they may be printed as "notes" underneath related sections of the Code. The codification is based on the content of the laws, however, not the vehicle by which they are adopted; so, for instance, if an appropriations act contains substantive, permanent provisions (as is sometimes the case), these provisions will be incorporated into the Code even though they were adopted as part of a non-permanent enactment.For example, the Department of Defense Appropriations Act of 2006, , (2005)—a time-specific appropriations act that the President signed into law on December 30, 2005—contains in its Division A, Title X the Detainee Treatment Act of 2005 ("DTA"). The DTA set out, among other things, permanent provisions governing standards for interrogation of persons in Defense Department custody, prohibitions on cruel and unusual punishment, and procedures for status review of extraterritorial detainees. See id. at div. A, tit. X, §§ 1001–1006, –44. Notably, DTA section 1002 was printed as a note to ; DTA section 1003 was codified as (though the section has not yet been enacted into positive law); and DTA section 1005(e)(1) codified a new subsection (e) of (which became positive law upon the DTA's enactment).
