n14 The Court's criticism, ante, at 16-17, deftly conflates two distinct questions: is the price on procedurally correct and noncollusive sale presumed irrebuttably to be reasonably equivalent value (the question before us) and, if not, what are the criteria (a question not raised here but explored by courts that have rejected the irrebuttable presumption)? What is "plain" is the answer to the first question, thanks to the plain language, whose meaning is confirmed by policy and statutory history. The answer to the second may not be plain in the sense that the criteria might be self-evident, see supra, n. 13, but want of self-evidence hardly justifies retreat from the obvious answer to the first question. Courts routinely derive criteria, unexpressed in a statute, to implement standards that are statutorily expressed, and in a proper case this Court could (but for the majority's decision) weigh the relative merits of the subtly different approaches taken by courts that have rejected the irrebuttable presumption.
