Amendment in the Nature of a Substitute

Definition: An amendment intended to replace the entire text of a bill.

Used in a sentence: The bill’s sponsor proposed an amendment in the nature of a substitute in order to correct for a number of errors in the original bill text.

History:The process of proposing an Amendment in the Nature of a Substitute is used by either the House or the Senate to replace the entire text of a piece of legislation. There are three main instances where this is commonly used: when the full chamber agrees to adopt an amendment that substitutes the entire text to correct for minor issues such as line numbering or typographical errors; when the whole chamber accepts a large amendment package ‘en bloc’ from the committee of jurisdiction allowing for second degree amendments to be filed; and during the appropriations process especially in the Senate. The origination clause of the Constitution requires that all bills raising or appropriating money originate in the House of Representatives. For this reason, the Senate will often take a House bill and substitute its complete language prior to amending the bill, maintaining the House bill name and number but using the Senate’s language and technically complying with the origination clause.
