Textualism is a formalist theory in which the interpretation of the law is primarily based on the ordinary meaning of the legal text, where no consideration is given to non-textual sources, such as: intention of the law when passed, the problem it was intended to remedy, or significant questions regarding the justice or rectitude of the law.
The textualist will "look at the statutory structure and hear the words as they would sound in the mind of a skilled, objectively reasonable user of words." The textualist thus does not give weight to legislative history materials when attempting to ascertain the meaning of a text. Textualism is often erroneously conflated with originalism, and was advocated by US Supreme Court Justices such as Hugo Black and Antonin Scalia; the latter staked out his claim in his 1997 Tanner Lecture: "[it] is the law that governs, not the intent of the lawgiver." Oliver Wendell Holmes, Jr., although not a textualist himself, well-captured this philosophy, and its rejection of intentionalism: "We ask, not what this man meant, but what those words would mean in the mouth of a normal speaker of English, using them in the circumstances in which they were used ... We do not inquire what the legislature meant; we ask only what the statutes mean."
Textualist judges have contended, with much practical impact, that courts should not treat committee reports or sponsors' statements as authoritative evidence of legislative intent. These judges base their resistance to that interpretive practice on two major premises: first, that a 535-member legislature has no "genuine" collective intent concerning the proper resolution of statutory ambiguity (and that, even if it did, there would be no reliable basis for equating the views of a committee or sponsor with the "intent" of Congress as a whole); second, that giving weight to legislative history offends the constitutionally mandated process of bicameralism and presentment.
