Reconciliation is a process established under Section 310 of the Congressional Budget Act of 1974 ( P.L. 93-344 , as amended). The purpose of reconciliation is to change substantive law so that revenue and mandatory spending levels are brought into line with budget resolution policies. Reconciliation generally has been used to reduce the deficit through spending reductions or revenue increases, or a combination of the two. In some years, however, the reconciliation process also encompassed revenue reduction generally and spending increases in selected program areas. Reconciliation is a two-step process. Under the first step, reconciliation instructions are included in the budget resolution, directing one or more committees in each House to develop legislation that changes spending or revenues (or both) by the amounts specified in the budget resolution. If more than one committee in each House is given instructions, each instructed committee submits reconciliation legislation to its respective Budget Committee, which incorporates all submissions, without any substantive revision, into a single, omnibus budget reconciliation measure. Reconciliation procedures during a session usually have applied to multiple committees and involved omnibus legislation. Under the second step, the omnibus budget reconciliation measure is considered in the House and Senate under expedited procedures (for example, debate time in the Senate on a reconciliation measure is limited to 20 hours and amendments must be germane). The process culminates with enactment of the measure, thus putting the policies of the budget resolution into effect. Reconciliation, which was first used by the House and Senate in 1980, is an optional procedure, but it has been used in most years. Over the period covering from 1980 to the present, 20 reconciliation bills have been enacted into law and four have been vetoed. During the first several years' experience with reconciliation, the legislation contained many provisions that were extraneous to the purpose of reducing the deficit. The reconciliation submissions of committees included such things as provisions that had no budgetary effect, that increased spending or reduced revenues, or that violated another committee's jurisdiction. In 1985 and 1986, the Senate adopted the Byrd rule (named after its principal sponsor, Senator Robert C. Byrd) as a means of curbing these practices. Initially, the rule consisted of two components, involving a provision in a reconciliation act and a Senate resolution. The Byrd rule has been modified several times over the years. The purpose of this report is to briefly recount the legislative history of the Byrd rule, summarize its current features, and describe its implementation from its inception through the present. During the first five years that the Byrd rule was in effect, from late 1985 until late 1990, it consisted of two separate components—(1) a provision in statute applying to initial Senate consideration of reconciliation measures, and (2) a Senate resolution extending application of portions of the statutory provision to conference reports and amendments between the two houses. Several modifications were made to the Byrd rule in 1986 and 1987, including extending its expiration date from January 2, 1987, to January 2, 1988, and then to September 30, 1992, but the two separate components of the rule were preserved. In 1990, these components were merged together and made permanent when they were incorporated into the Congressional Budget Act (CBA) of 1974 as Section 313. There have been no further changes in the Byrd rule since 1990. The Byrd rule originated on October 24, 1985, when Senator Robert C. Byrd, on behalf of himself and others, offered Amendment No. 878 (as modified) to S. 1730 , the Consolidated Omnibus Budget Reconciliation Act (COBRA) of 1985. The Senate adopted the amendment by a vote of 96-0. In this form, the Byrd rule applied to initial Senate consideration of reconciliation measures. Senator Byrd explained that the basic purposes of the amendment were to protect the effectiveness of the reconciliation process (by excluding extraneous matter that often provoked controversy without aiding deficit reduction efforts) and to preserve the deliberative character of the Senate (by excluding from consideration under expedited procedures legislative matters not central to deficit reduction that should be debated under regular procedures). He opened his remarks by stating we are in the process now of seeing ... the Pandora's box which has been opened to the abuse of the reconciliation process. That process was never meant to be used as it is being used. There are 122 items in the reconciliation bill that are extraneous. Henceforth, if the majority on a committee should wish to include in reconciliation recommendations to the Budget Committee any measure, no matter how controversial, it can be brought to the Senate under an ironclad built-in time agreement that limits debate, plus time on amendments and motions, to no more than 20 hours. It was never foreseen that the Budget Reform Act would be used in that way. So if the budget reform process is going to be preserved, and more importantly if we are going to preserve the deliberative process in this U.S. Senate—which is the outstanding, unique element with respect to the U.S. Senate, action must be taken now to stop this abuse of the budget process. The Byrd amendment was included in modified form in COBRA of 1985 ( P.L. 99-272 ), which was not enacted into law until April 7, 1986, as Section 20001 (100 Stat. 390-391). The Byrd rule, in this form, thus became effective on April 7. As originally framed, the Byrd rule was set to expire on January 2, 1987. Over the years, the Senate has expanded and revised the Byrd rule through the adoption of two resolutions and the inclusion of provisions in four laws. Table 1 lists the laws and resolutions that have established and revised the Byrd rule. On December 19, 1985, the Senate adopted by voice vote a resolution ( S.Res. 286 ), sponsored by Senator Alan Simpson and others, that extended the application of portions of the statutory provision to conference reports and amendments between the two houses. Because the enactment of COBRA of 1985 was delayed until early 1986, the portion of the Byrd rule dealing with conference reports became effective first. The provisions of S.Res. 286 were set to expire on the same date as the provision in COBRA of 1985 (January 2, 1987). In the following year, the Senate was involved in two actions affecting the Byrd rule. First, the Senate adopted S.Res. 509 by voice vote on October 16, 1986. The measure, offered by Senator Alan Simpson and others, modified S.Res. 286 in a technical fashion. Second, the Omnibus Budget Reconciliation Act of 1986 was enacted into law, as P.L. 99-509 , on October 21, 1986. Section 7006 of the law made several minor changes in the Byrd rule and extended its expiration date by one year—until January 2, 1988. Further changes in the Byrd rule were made in 1987. These changes were included in a measure increasing the statutory limit on the public debt, modifying procedures under the Balanced Budget and Emergency Deficit Control Act of 1985, and making other budget process changes ( P.L. 100-119 , signed into law on September 29; see Title II (Budget Process Reform)). Section 205 of the law added an item to the list of definitions of extraneous matter in the Byrd rule and extended its expiration until September 30, 1992. In 1990, Congress and the President agreed to further modifications of the budget process by enacting the Budget Enforcement Act (BEA) of 1990 (Title XIII of the Omnibus Budget Reconciliation Act of 1990). Section 13214 of the law made significant revisions to the Byrd rule and incorporated it (as permanent law) into the CBA of 1974 as Section 313 (2 U.S.C. 644). Finally, the Budget Enforcement Act of 1997 (Title X of the Balanced Budget Act of 1997) made minor technical changes in Section 313 of the CBA of 1974 to correct drafting problems with the BEA of 1990. A Senator opposed to the inclusion of extraneous matter in reconciliation legislation has two principal options for dealing with the problem. First, a Senator may offer an amendment (or a motion to recommit the measure with instructions) that strikes such provisions from the legislation. Second, under the Byrd rule, a Senator may raise a point of order against extraneous matter. The Byrd rule is a relatively complex rule that applies to two types of reconciliation measures considered pursuant to Section 310 of the CBA of 1974—reconciliation bills and reconciliation resolutions. (A reconciliation resolution could be used to make changes in legislation that had passed the House and Senate but had not yet been enrolled and sent to the President. The practice of the House and Senate has been to consider only reconciliation bills.) In general, a point of order authorized under the Byrd rule may be raised in order to strike extraneous matter already in the bill as reported or discharged (or in the conference report), or to prevent the incorporation of extraneous matter through the adoption of amendments or motions. A point of order may be raised against a single provision or two or more provisions (as designated by title or section number, or by page and line number), and may be raised against a single amendment or two or more amendments. The chair may sustain a point of order as to all of the provisions (or amendments) or only some of them. Once material has been struck from reconciliation legislation under the Byrd rule, it may not be offered again as an amendment. A motion to waive the Byrd rule, or to sustain an appeal of the ruling of the chair on a point of order raised under the Byrd rule, requires the affirmative vote of three-fifths of the membership (60 Senators if no seats are vacant).
