DAVIS Kennedy, J., dissenting portation “to give information under oath . . . as the Attorney General may deem fit and proper.” 353 U. S., at 195. The Court held that although the plain language “appears to confer upon the Attorney General unbounded authority to require whatever information he deems desirable of aliens whose deportation has not been effected within six months,” id., at 199, the constitutional doubt this interpretation would raise meant the language would be construed as limited to the provision of information “reasonably calculated to keep the Attorney General advised regarding the continued availability for departure of aliens whose deportation is overdue,” id., at 202. In Witkovich the interpretation of the text was in aid of the statutory purpose; in the instant cases the interpretation nullifies the statutory purpose. Here the statute by its own terms permits the Attorney General to consider factors the Court now makes irrelevant. The majority’s unanchored interpretation ignores another indication that the Attorney General’s detention discretion was not limited to this truncated period. Section 1231(a)(6) permits continued detention not only of removable aliens but also of inadmissible aliens, for instance those stopped at the border before entry. Congress provides for detention of both categories within the same statutory grant of authority. Accepting the majority’s interpretation, then, there are two possibilities, neither of which is sustainable. On the one hand, it may be that the majority’s rule applies to both categories of aliens, in which case we are asked to assume that Congress intended to restrict the discretion it could confer upon the Attorney General so that all inadmissible aliens must be allowed into our community within six months. On the other hand, the majority’s logic might be that inadmissible and removable aliens can be treated differently. Yet it is not a plausible construction of § 1231(a)(6) to imply a time limit as to one class but not to another. The text does not admit of this possibility. As a result, it is difficult to see why “[a]liens who have not yet gained initial admission
