Trade Promotion Authority and the Korea Free Trade Agreement 
 
Summary 
On June 30, 2007, U.S. and South Korean officials signed the Korea Free Trade Agreement 
(Korea FTA or KORUS FTA) for their respective countries. It is one of three free trade 
agreements currently awaiting submission to Congress for approval and implementing legislation. 
In June 2010, the Obama Administration announced plans to seek Congress’s approval for the 
Korea FTA after first engaging in talks with South Korea over U.S. concerns with the agreement 
as signed, particularly over its provisions involving market access for U.S. autos. These talks 
were concluded on December 3, 2010 with a text that has been referred to as a “supplemental 
agreement” or “supplementary deal” to the 2007 Korea FTA. 
The Executive, in consultation with Congress, is expected to draft legislation approving and 
implementing the Korea FTA and submit the resulting “implementing bill” to Congress during the 
first session of the 112th Congress. This legislation will be entitled to consideration in Congress 
under expedited (“fast track”) legislative procedures if it satisfies the requirements of the 
Bipartisan Trade Promotion Authority Act of 2002 (Trade Act of 2002). In particular, the 
implementing bill must: (1) approve the agreement “entered into” in 2007; and (2) include 
provisions enacting, amending, or repealing existing U.S. laws only to the extent that the 
provisions are “necessary or appropriate” for the implementation of the agreement “entered into” 
in 2007. Each chamber of Congress, acting independently of the other, has the authority to 
determine for itself whether the Korea FTA implementing bill conforms with these requirements. 
In each chamber where the bill is found to satisfy the terms of the Trade Act of 2002, the bill will 
be entitled to receive an up-or-down vote without amendment and with limited debate.  
It is difficult to predict with certainty how the 2010 changes and the late date at which they were 
concluded might affect Congress’s decision to consider the Korea FTA implementing bill under 
the fast track procedures. However, the effect of side agreements on the fast track eligibility of the 
implementing legislation for the North American Free Trade Agreement (NAFTA) may be 
instructive. In that case, the Executive concluded supplemental agreements to the trade agreement 
after the agreement was signed and trade promotion authority had expired. These agreements 
were treated as executive agreements, circumventing the need for their express approval by 
Congress, but the implementing bill nevertheless authorized U.S. participation in the two 
agreements. Arguably, the NAFTA supplemental agreements may be characterized as having 
received congressional approval.  
Although members expressed concern about the use of the fast track procedures to consider the 
NAFTA implementing bill, no member formally challenged the bill’s eligibility for fast track 
consideration. To challenge the use of the fast track procedures to consider the Korea FTA 
implementing bill, a member must raise an objection. The bill’s eligibility for fast track 
consideration will then be resolved by the chamber in which the objection was raised. Either 
chamber may also decide, as an exercise of its rulemaking power, to waive, suspend, or repeal its 
grant of fast track authority.  
If the Korea FTA implementing bill is deemed ineligible for—or otherwise denied—fast track 
consideration, the bill, in its entirety, may be considered under the regular procedures of each 
chamber. Under these procedures, the bill, like other pieces of legislation, might not be brought 
up for a vote or might be passed with amendments. The Jordan Free Trade Agreement was 
statutorily implemented under regular procedures.

Trade Promotion Authority and the Korea Free Trade Agreement 
 
Introduction 
A free trade agreement is an agreement involving two or more trading partners under which 
tariffs and trade barriers are reduced or eliminated. Today, the United States has free trade 
agreements with 17 countries, including nations in Asia, the Middle East, South and Central 
America, and Africa. Historically, these agreements have been approved by majority vote of each 
house rather than by two-thirds vote of the Senate—that is, they have been treated as 
congressional-executive agreements rather than as treaties.1 In a succession of statutes, Congress 
has authorized the President to negotiate and enter into agreements reducing tariff and nontariff 
barriers for limited periods, while permitting trade agreements negotiated under this authority to 
enter into force for the United States once they are approved by both houses and other statutory 
conditions are met. 
The most recent of these statutes is the Bipartisan Trade Promotion Authority Act of 20022 (Trade 
Act of 2002) in which Congress authorized the President to negotiate and enter into trade 
agreements before July 1, 2007 so long as the agreements satisfied certain conditions and were 
subject to congressional review. Acting on that authority, the Executive negotiated several trade 
agreements, including the Korea Free Trade Agreement (Korea FTA or KORUS FTA), which was 
signed by officials for the two countries on June 30, 2007. The Korea FTA is one of three 
agreements that were negotiated under the terms of the Trade Act of 2002 but have yet to be 
submitted to Congress for approval and implementation.3 
Under section 2105 of the Trade Act of 2002,4 the Korea FTA will enter into force for the United 
States “if (and only if)” the four conditions stated in section 2105(a) of the statute are satisfied. 
Broadly described, these four requirements are as follows: 
•  The President, at least 90 calendar days before entering the trade agreement, 
notifies Congress of the President’s intention to enter into the agreement; 
•  The President, within 60 days after entering into the agreement, submits to 
Congress a description of the changes to U.S. law that the President considers 
required to bring the United States into compliance with the agreements; 
•  The President submits to Congress a copy of the final legal text of the agreement, 
a draft of the implementing bill, a statement of administrative action, and certain 
supporting information; and 
•  The implementing bill is enacted into law.

3 The two other agreements are the U.S.-Panama Free Trade Agreement and the U.S.-Colombia Free Trade Agreement. 
Unlike the Korea FTA and the Panama FTA, implementing legislation for the Colombia FTA was submitted to 
Congress in April 2008. H.R. 5724/S. 2830, 110th Cong. At that time, the House voted to make fast-track authority 
inapplicable. H.Res. 1092, 110th Cong. (“[S]ection 151(e)(1) and section 151(f)(1) of the Trade Act of 1974 shall not 
apply in the case of the bill (H.R. 5724) to implement the United States-Colombia Trade Promotion Agreement.”).

Moreover, once the implementing bill is introduced in Congress, it must meet additional 
requirements to be considered under the expedited (“fast track”) procedures. Although a range of 
measures have historically been eligible for similar expedited procedures under other statutes, 
when an implementing bill for a trade agreement is statutorily authorized for fast track 
consideration, the bill is known as having Trade Promotion Authority (TPA), a label that reflects 
the short title of the 2002 Act. One of the purposes of these expedited procedures in the trade area 
is to ensure that Congress will be able to consider and vote on the implementing bill regardless of 
the congressional leadership’s position on the agreement. A second purpose is to prevent the 
legislation from being blocked by filibuster or amended to an extent that forces the two countries 
to reenter negotiations.5 
As signed on June 30, 2007, the Korea FTA was entered into before the July 1, 2007, deadline. 
Therefore, assuming that its implementing bill satisfies the remaining statutory requirements, it 
will be eligible for consideration under the fast track procedures. However, the bill’s eligibility 
for TPA may be complicated by changes to the agreement that were only recently negotiated.  
2010 Changes to the Korea FTA  
In the summer of 2010, the Obama Administration announced plans to reengage in talks with 
South Korea over aspects of the Korea FTA, particularly its provisions involving market access 
for U.S. autos.6 These talks concluded on December 3, 2010 when the two sides agreed to make 
certain additions and modifications to the 2007 agreement. The media has referred to these 
changes collectively as a “supplementary agreement” or “supplementary deal” to the Korea FTA. 
U.S. and Korean trade officials were scheduled to craft the legal text of this “supplementary deal” 
during December 2010 meetings.7 To date, that text has not been released.  
Reports of the deal, however, suggest that the changes primarily modify Korea’s obligations and 
clarify the time frames under which the United States must make the tariff reductions that were 
required by the original agreement.8 These reports also indicate that the United States has agreed 
to extend certain L-visas for Korean workers dispatched to offices in the United States, delay the 
date by which Korea is obligated to eliminate its tariffs on certain pork products, and expand the 
so-called “snapback” clause under which either party may suspend automobile tariff concessions 
following certain outcomes in a dispute settlement proceeding.9

Korean truck imports).

Trade Promotion Authority and the Korea Free Trade Agreement 
 
Typically, an implementing bill sets two tasks before Congress. First, in order for the terms of a 
free trade agreement to “enter into force”—that is, constitute binding international 
commitments—for the United States, Congress must vote to approve the agreement.10 Second, for 
those commitments to have legal effect domestically, Congress must “implement” them by 
repealing or amending relevant U.S. law or enacting new statutory authorities to ensure U.S. 
comply with the agreement. Accordingly, as a result of the newly negotiated changes to the Korea 
FTA, two questions arise. First, can these changes enter into force for the United States, that is, 
create an international obligation, without congressional approval? In order to do so, Congress 
must treat the “supplementary agreement” as an executive agreement that does not need to be 
submitted for its consideration.11 Second, can the changes carry the force of law domestically 
absent congressional action? To do this, the “supplementary agreement” must be characterized as 
self-executing—that is, requiring no changes to the U.S. code to become enforceable in court by 
private parties or capable of being performed by U.S. agencies—and therefore not need to be 
submitted to Congress for implementation.12  
Ultimately, if, in its entirety, the “supplementary agreement” constitutes a self-executing 
executive agreement, the 2010 changes may have no implications for the fast track consideration 
of the Korea FTA because they would not be included in the implementing bill. However, in the 
absence of the text of the changes to which U.S. and Korean officials agreed, it is difficult to 
predict the extent to which the changes might require congressional approval or implementation. 
Accordingly, this report assesses the fast track eligibility of an implementing bill for the Korea 
FTA that either treats the 2010 changes as part of the agreement that was “entered into” in 2007 
or effectively includes them in the provisions implementing the 2007 agreement. 
Fast Track Consideration of the Implementing Bill 
Trade agreements are not the only type of measure to traditionally receive consideration under the 
expedited legislative procedure known as “fast track.” For example, House and Senate 
consideration of budget resolutions and reconciliation bills are also generally governed by fast 
track procedures.13 However, the authority to apply fast track procedures to legislation approving 
and implementing a free trade agreement often goes by the name “Trade Promotion Authority” 
(TPA).

undertakes obligations expressed in international trade agreements is the provision of the implementing bill 
“approving” the agreement at issue).  
11 For a fuller discussion of executive agreements, see CRS Report RL32528, International Law and Agreements: Their 
Effect Upon U.S. Law, by Michael John Garcia. Congress could also treat the “supplementary agreement” as a 
voluntary agreement that does not require congressional approval, but the commitments contained therein would then 
be considered voluntary rather than internationally binding for the United States. See infra note 23 and accompanying 
text.

Fast track procedures promote timely committee and floor action of the legislation at issue. The 
Trade Act of 2002, for example, mandates that legislation approving and implementing a free 
trade agreement that is entitled to consideration under the fast track procedures receive an up-or-
down vote in Congress without amendment and with limited debate.14 However, the Trade Act of 
2002 conditions a bill’s eligibility for fast track consideration on its satisfaction of certain 
statutory requirements.15 In particular, to satisfy the act’s definition of an “implementing bill,” the 
legislation must contain three components: 
•  a provision approving a trade agreement “entered into” in conformity with the 
Trade Act of 2002; 
•  a provision approving a statement of administrative action, if any, proposed to 
implement that agreement; and 
•  if changes to U.S. law are required to implement the trade agreement, provisions 
“repealing or amending existing laws or providing new statutory authority” that 
are “necessary or appropriate to implement” the agreement.16 
In light of the 2010 changes to the Korea FTA, questions have arisen over whether legislation 
containing those changes will meet these requirements for fast track consideration. The two 
requirements that may have the greatest negative implications for the fast track consideration of 
the Korea FTA and its implementing bill are: (1) the requirement that the bill approve an 
agreement that was “entered into” before the July 1, 2007 deadline for fast track consideration; 
and (2) the requirement that any bill provisions repealing, amending, or enacting U.S. law be 
“necessary or appropriate” for the implementation of the 2007 agreement.  
Does the Bill Approve an Agreement “Entered Into” in 2007? 
As mentioned above, an implementing bill is entitled to receive fast track consideration only if, 
inter alia, it includes a provision approving a trade agreement that was “entered into” in 
conformity with the Trade Act of 2002. The phrase “entered into” has generally been understood 
to mean “signed,” rather than “implemented,” by the parties. Furthermore, to be in conformity 
with the Trade Act of 2002, that agreement must have been “entered into” before July 1, 2007.17  
The 2010 changes to the Korea FTA were not “entered into” before the deadline for fast track 
procedures authorized by the Trade Act of 2002. However, the Trade Act of 2002 seems to draw a

of either chamber which satisfies the Trade Act of 2002’s definition of an implementing bill); id. at § 2191(d) 
(prohibiting amendments to a trade agreement’s implementing bill or approval resolution and prohibiting motions to 
suspend this prohibition by unanimous consent); id. at § 2191(e) (stating that, at the close of the 45th day after the 
implementing bill’s introduction, the bill is automatically discharged from any committee to which it was referred); id. 
at § 2191(f), (g) (stating that an amendment to a motion to proceed to the consideration of an implementing bill shall 
not be in order in either chamber and the floor debate in either chamber may not exceed 20 hours).

17 19 U.S.C. §§ 3803(b)(1)(C). See also id. at § 3805(a) (stating that for an “agreement entered into under section 
3803(b)” to enter into force, a description of the changes to existing laws that the President considers to be required to 
bring the U.S. into compliance with that agreement must be submitted to Congress within 60 days after the agreement 
is signed, and, at some point thereafter, a “copy of the final legal text of the agreement” must be submitted to Congress 
with, inter alia, a draft of an implementing bill.)

distinction between the agreement that was signed—which must be the one being approved by 
Congress—and the “final legal text” of that agreement—which is the one that the President must 
submit to Congress with the implementing bill.18 This distinction suggests that the text of the 
agreement that was signed and the agreement that is submitted to Congress for approval need not 
be identical, and, in turn, some changes may be made to the original agreement without 
disqualifying the implementing bill from fast track consideration.19 
In the absence of the text of the 2010 changes, it is difficult to predict whether members are likely 
to view them as falling within this category of acceptable changes to a trade agreement. The 
question may hinge on whether those changes can “enter into force” for the United States absent 
congressional action. In other words, it could depend on whether some or all of the terms of the 
“supplementary deal” can be treated by Congress as an executive agreement or otherwise become 
binding for the United States without receiving congressional approval.20  
Absent congressional approval or authorization, the “supplementary deal” could qualify as an 
executive agreement if it was entered into under either (1) an earlier agreement that received 
congressional approval, either prospectively or retroactively; or (2) the President’s sole 
constitutional authority.21 Although the Constitution is understood to vest the President with the 
authority to conduct foreign relations and, as part of that, negotiate international agreements,22 it 
is unclear whether—and to what extent—these powers might encompass some degree of 
executive authority related to foreign commerce.23 Congress, on the other hand, has express 
constitutional authority to (1) “lay and collect taxes, duties, imposts, and excises;” (2) “regulate 
                                                
18 See 19 U.S.C. §§ 3803(b)(3); 3805(a)(1)(C). 
19 See id. at § 3805(a)(1). 
20 See Senate Committee on Finance, supra note 10, at 34 (indicating that the purpose of the approval provision is to 
permit “the agreement to enter into force with respect to the United States in accordance with the terms of the 
agreement”).

Effect Upon U.S. Law, by Michael John Garcia.

Corp., 299 U.S. 304 (1936); Saikrishna B. Prakash and Michael Ramsey, The Executive Power over Foreign Affairs,

23 Compare e.g., Consumers Union of U.S., Inc. v. Kissinger, 506 F.2d 136 (D.C. Cir. 1974), cert denied, 421 U.S. 
1004 (1975) (finding that the Executive has the authority to enter into voluntary agreements that limit exports to the 
United States) with United States v. Guy W. Capps Inc., 204 F.2d 655, 660 (4th Cir. 1953) (“Imports from a foreign 
country are foreign commerce subject to regulation, so far as this country is concerned by Congress alone. The 
[E]xecutive may not by-pass congressional limitations regulating such commerce by entering into an agreement with 
the foreign country that the regulation be exercised by that country through its control over exports.”). In Consumers 
Union, the question facing the D.C. Circuit was whether the Executive’s negotiation of voluntary import restraints with 
Japanese and European steel producer associations constituted an unconstitutional regulation of foreign commerce. 
Consumers Union, 506 F.2d at 138-39. The court found that the Executive had not regulated foreign commerce so 
much as received “assurances of voluntary restraint” from foreign producers, and therefore the court held that the 
Executive’s negotiation of voluntary import restraints did not conflict with Congress’s exclusive authority over 
“enforceable import restrictions.” Id. at 143. In other words, the President may have the authority to enter into 
voluntary trade agreements absent congressional authority, but the obligations contained therein will not be binding for 
the United States. See id. In Guy W. Capps Inc., the Fourth Circuit considered whether the Executive’s powers included 
the authority to enter into an “executive agreement” under which Canada would refrain from placing certain permitting 
restrictions on potato exports to the United States and the United States would refrain from imposing quantitative 
limitations or fees on Canadian potato exports. Guy W. Capps Inc., 204 F.2d at 657. The court ruled that the President 
lacked the authority to enter this “executive agreement” because entering an international agreement under which a 
foreign country agrees to regulate imports is the same as regulating imports directly, and, therefore, an exercise of 
Congress’s exclusive constitutional authority over foreign commerce. Id. at 660.  
Congressional Research Service

commerce with foreign nations;” and (3) “make all laws which shall be necessary and proper” to 
carry out these specific powers.24 Accordingly, it seems unlikely that the “supplementary deal” 
could qualify as an executive agreement on the grounds that the President has the sole 
constitutional authority to enter into it.  
However, to the extent that the 2010 changes primarily clarify the text, by, for example, providing 
time frames and guidelines for the implementation of the current provisions of the 2007 
agreement, the “supplementary deal” may well be amenable to treatment as an executive 
agreement—particularly if the original 2007 trade agreement receives congressional approval.25 
If, on the other hand, the implementing bill approves substantively new U.S. commitments—
particularly those that fall within the scope of one of Congress’s explicit constitutional powers—
that were agreed to after the original text was signed, the bill would most likely be ineligible for 
fast track procedures because these changes could not be treated as an executive agreement.26 
Therefore, once the text of the “supplementary deal” is released, provisions whose substance 
resembles fundamentally new U.S. obligations—and not mere clarifications of the content of, or 
schedule for, achieving a pre-existing U.S. commitment—may warrant close scrutiny to assess 
the Executive’s authority to commit the United States to those terms.27  
There is historical precedent for treating supplemental agreements to a trade agreement as 
executive agreements when the supplemental agreements were signed after the expiration of 
TPA.28 The George H. W. Bush Administration signed the North American Free Trade Agreement 
(NAFTA) on September 18, 1992. In doing so, NAFTA was “entered into” before the legislative 
authority for its fast track status, the Omnibus Trade and Competitiveness Act of 1988 (Trade Act 
of 1988, P.L. 100-418, 102 Stat. 1107), expired on June 1, 1993. However, having indicated 
during his campaign that he would not sign legislation implementing NAFTA until new 
“supplemental agreements” on labor and the environment had been negotiated,29 President 
Clinton commenced side agreement negotiations with Mexico and Canada after the 1992 signing 
of NAFTA. Ultimately, two side agreements, the North American Agreement on Environmental 
Cooperation (NAAEC) and the North American Agreement on Labor Cooperation (NAALC), 
were signed by officials for the United States, Mexico, and Canada on September 14, 1993, more 
than three months after the expiration of TPA. The United States Trade Representative (USTR) 
released a letter stating that these supplemental agreements were not “trade agreements for 
purposes of fast track procedures”30 and referred to the NAAEC and NAALC as executive

28 Other trade agreements, including the Peru Free Trade Agreement and the Dominican Republic-Central America-
United States Free Trade Agreement (CAFTA-DR or CAFTA) have been modified after they were “entered into,” but 
few have been modified after the expiration of the legislative authority for the fast track status of the agreement’s 
implementing legislation.

agreements instead.31 In accordance with this view, the President submitted these supplemental 
agreements to Congress in simultaneity with the text of NAFTA but only to inform congressional 
consideration of the implementing bill.32 The President did not seek—and did not receive—
congressional approval of the two agreements. Instead, the provision of the implementing bill that 
approved NAFTA stated that Congress approved the agreement that was “entered into on 
December 17, 1992.”33  
Although the Executive’s characterization of the NAFTA side agreements was ultimately 
successful, it did not go unchallenged in the Senate. In particular, the late Senator Ted Stevens 
expressed strong concerns that, by considering the implementing bill under the fast track 
procedures, Congress was permitting the Executive to usurp unconstitutionally broad authority to 
enter into and participate in international agreements. He said: 
We are setting a precedent—at the request of the Executive—giving the Executive broad, 
broad authority to negotiate nontrade agreements under protections of the fast track 
procedure. As I remember my constitutional history, the Framers of our Constitution had 
deep fears of a runaway Executive, an Executive that might go off and make agreements 
with foreign nationals, foreign governments, contrary to the best interests of our people.34 
However, the President did not leave the side agreements out of the implementing bill entirely, 
which may have lessened the persuasiveness of Senator Stevens’s argument for some members. 
Specifically, the NAFTA implementing bill included a provision authorizing U.S. participation in 
the supplemental agreements.35 Although Senator Stevens disapproved of that provision as well,36 
Congress enacted the bill in its entirety, which may permit a characterization of the NAAEC and 
NAALC as having received congressional approval after all.37 
The treatment of NAFTA’s side agreements may illustrate how Congress and the Executive have 
approached substantive changes to a trade agreement that were negotiated after the expiration of 
TPA. However, the Korea FTA may also provide the President with even greater authority than 
NAFTA did to commit the United States to a changed version of the underlying trade agreement 
without obtaining congressional approval. The Korea FTA expressly permits its parties to modify 
the agreement without abiding by their “applicable [domestic] legal procedures.”38 NAFTA does 
not include this language. Consequently, NAFTA could not be altered without Congress’s

approval even after the text of NAFTA was approved and implemented by Congress.39 To a 
limited extent, the opposite is true of the Korea FTA, which states that officials of both parties 
may, by consensus, “make modifications to the commitments.”40 This difference has two possible 
implications for the modification of the Korea FTA. First, the United States and Korea may be 
able to bring the 2010 changes into force without congressional approval as soon as the 
agreement that was “entered into” in 2007 enters into force. The second implication is that 
because the 2010 changes can enter into force without congressional action once the 2007 
agreement enters into force, the Executive may seek to characterize the 2010 “supplementary 
deal” as an executive agreement authorized by the earlier agreement.41 However, this 
characterization of the agreement would not be controlling for the purposes of the fast track 
procedures. As described below, if a member objects to considering the Korea FTA implementing 
bill under the fast track procedures, the bill’s eligibility for TPA will be determined under the 
chamber’s procedural rules and not by the Executive Branch. 
Does the Bill Make “Necessary and Appropriate” Changes? 
The second condition that the Korea FTA implementing bill must satisfy in order to be entitled to 
fast track consideration is the Trade Act of 2002’s requirement that provisions in the bill that 
repeal, amend, or enact U.S. law must be “necessary or appropriate” to implement the 2007 
agreement.42 The legislative history of the Trade Act of 2002 suggests that the phrase “necessary 
or appropriate” should be strictly interpreted, but it is unclear whether it has, in practice, been 
narrowly construed.43 In particular, when other trade agreements have been modified after they 
were signed, some members of Congress have questioned whether the modifications are 
“necessary or appropriate” and therefore warrant treatment under the same fast track procedures 
as the rest of the implementing bill. 
For example, the definition of “necessary or appropriate” was discussed during the floor debates 
on the NAFTA implementing bill. As mentioned above, although the Clinton Administration did 
not seek congressional approval of the NAFTA side agreements in the implementing bill, it did 
include a provision in the bill seeking congressional authority to “participate” in the agreements.44 
                                                
39 Absent a provision to the contrary, agreements are amended by the same procedures under which they were 
approved. CONGRESSIONAL RESEARCH SERVICE, TREATIES AND OTHER INTERNATIONAL AGREEMENTS: THE ROLE OF THE 
UNITED STATES SENATE, A STUDY PREPARED FOR THE SENATE COMM. ON FOREIGN RELATIONS 178 (2001) (S. Prt. 106-
71). Accordingly, a trade agreement that is treated as a congressional-executive agreement could generally be amended 
only if Congress approved of the amendment. See id.  
40 Korea FTA, Arts. 22.2.3(c), 22.7. However “amendments” to the agreement, as opposed to “modifications,” are still 
subject to the parties’ “respective applicable legal requirements,” which is the same requirement placed on amendments 
under NAFTA. See Korea FTA, Art. 24.2; NAFTA, Art. 2202.2. As the word “modifications” in the Korea FTA is 
undefined, it is unclear from the text what changes would constitute modifications rather than amendments.  
41 The opposing perspective, however, is that until Article 22.2.3 of the Korea FTA is approved by Congress, it has no 
legal bearing on the agreement’s fast track status.

Trade Promotion Authority and the Korea Free Trade Agreement 
 
On the floor, some members suggested this authorization of U.S. participation in the side 
agreements was not “necessary or appropriate” to the implementation of the original NAFTA and 
therefore was not eligible for fast track consideration. Perhaps the most vociferous advocate of 
this view was Senator Ted Stevens, who argued:  
The “necessary and appropriate” language is only involved if changes in existing law or new 
statutory authority are required to implement such trade agreements. There is no authority 
whatsoever in the law to include separate executive agreements in this legislation. And they 
should not be here ... There is no legal authority for these side agreements to be before the 
Congress under the fast-track procedures.45 
Senator Baucus sought to rebut Senator Stevens’s arguments on the grounds that the President has 
broad constitutional authority to execute agreements and the “fast track statutory authority gives 
the President the ability to negotiate agreements and provisions appropriate to trade laws,”46 a 
much broader term. The debate illustrates different opinions as to which standard in the Trade Act 
of 2002’s “necessary or appropriate” clause should carry greater weight. Because the NAFTA 
implementing bill was ultimately enacted, one could argue that its passage set a precedent for 
broad interpretations, like the one offered by Senator Baucus, of the “necessary or appropriate” 
clause. This view would support the position that even if the Korea FTA includes provisions 
implementing the 2010 changes, the bill is nevertheless eligible for fast track consideration under 
the terms of the Trade Act of 2002. 
Options Available to Congress 
Although legislative procedure is most often dictated by the standing rules of the House and 
Senate, Congress generally enacts fast track procedures into law instead of amending either 
body’s standing rules. However, the statutory grant of TPA to a trade agreement’s implementing 
bill remains “an exercise of the rulemaking power of the House of Representatives and the 
Senate, respectively.”47 Accordingly, Congress retains the same authority over TPA as it has over 
other rules of legislative procedure, and each chamber may waive, suspend, or repeal fast track 
authority for legislation implementing the Korea FTA.48 The Trade Act of 2002 authorizes either 
chamber to pass a resolution making the fast track procedures inapplicable to an implementing 
bill on the grounds that either the Executive failed to follow certain procedures49 or the agreement 
“fail[s] to make progress in achieving the purposes, policies, priorities, and objectives” specified 
by the Trade Act of 2002.50

Most likely, the Senate and House parliamentarians will be consulted about the Korea FTA 
implementing bill before it is introduced in either chamber. If an implementing bill is introduced 
and a member is concerned that it not entitled to receive fast track consideration, the member may 
raise an objection. At that point, the bill’s eligibility for fast track status will be resolved under the 
chamber’s procedural rules. In the House, the presiding officer will rule on the availability of fast 
track procedures for the implementing bill with the guidance of the House parliamentarian.51 A 
similar procedure would be followed in the Senate if a member there raised a point of order. In 
principle, a decision on the availability of the fast track procedures could be appealed to the full 
body. Ultimately, a chamber’s decision as to whether the implementing bill qualifies for fast track 
consideration will be made independently of any decision reached in the other chamber. 
In the context of the NAFTA implementing bill, Senator Stevens strenuously argued against the 
bill’s eligibility for fast track consideration, but he did not raise a point of order.52 Instead, he 
proposed an amendment to strike the language in the NAFTA implementing bill that authorized 
U.S. participation in the NAAEC and NAALC.53 The amendment could not be considered, 
however, because amendments are not permitted for bills considered under the fast track 
procedures.54 As a result, it appears that neither the House nor the Senate was asked to formally 
determine the NAFTA implementing bill’s eligibility for fast track consideration.  
If a member in either chamber raises an objection to the fast track consideration of the Korea FTA 
and the bill is deemed ineligible for TPA under the Trade Act of 2002, then the bill will be 
considered under the regular procedures of that chamber. Under these procedures, the bill, like 
other pieces of legislation, might not be brought up for a vote or it might be amended. In addition, 
the chamber could grant fast track authority to the bill even though it was deemed ineligible under 
the terms of the Trade Act of 2002. Although some believe that political hurdles will prevent a 
trade agreement’s implementing bill from being passed without the fast track procedures, 
implementing legislation for the U.S.-Jordan Free Trade Agreement was enacted under regular 
procedures after fast track authorities added in the Omnibus Trade and Competitiveness Act of 
198855 expired. On the other hand, Congress may have treated the Jordan agreement with unusual 
deference because of Jordan’s unique geopolitical role in the Middle East peace process.56 It is

difficult to predict whether Congress would feel that diplomatic reasons warrant affording the 
Korea FTA similarly deferential treatment.57 
Conclusion 
In order for the Korea FTA to enter into force for the United States, the agreement must receive 
congressional approval. In turn, for the commitments contained in the Korea FTA to have legal 
effect domestically, Congress must implement the agreement—that is, repeal or amend current 
U.S. law or enact new statutory authority. The Korea FTA, which is expected to develop out of 
consultations between the Executive and Congress, will be designed to achieve these goals. Once 
the bill is formally submitted to Congress, it will be entitled to fast track consideration if it 
satisfies the requirements of the Trade Act of 2002. In particular, the implementing bill must: (1) 
approve the agreement that was “entered into” in 2007; and (2) include provisions enacting, 
amending, or repealing existing U.S. laws to the extent “necessary or appropriate” for the 
implementation of that agreement that was “entered into” in 2007. 
It is difficult to predict whether Congress will view the “supplementary deal” reached in 
December 2010, as disqualifying an implementing bill from fast track consideration. Because the 
“supplementary deal” was agreed upon several years after the expiration of TPA, it could present 
two problems for the fast track eligibility of implementing legislation. First, the implementing bill 
could be disqualified from fast track consideration on the grounds that it approves an agreement 
that was not entered into in conformity with the Trade Act of 2002. Second, the bill could be 
disqualified from fast track consideration because it effects changes to U.S. law that are not 
“necessary or appropriate” for the implementation of the Korea FTA that was entered into in 
2007. 
However, the enactment of the NAFTA implementing bill provides historical precedent for 
congressional approval and implementation of a free trade agreement that was modified after the 
expiration of TPA but was nevertheless considered under the fast track procedures. In that case, 
the two NAFTA side agreements were characterized as executive agreements, and, accordingly, 
the implementing bill did not express approval for them. Some members disapproved of this 
approach, arguing that by not approving the side agreements Congress gave the Executive 
unconstitutionally broad authority to enter into international agreements. The NAFTA 
implementing bill did, however, include a provision authorizing U.S. participation in those side 
agreements. Some members protested this move as well, arguing that the authorization was not 
“necessary or appropriate” for the implementation of the original NAFTA, but Congress passed 
the implementing bill in its entirety. As a result, one can characterize the two side agreements as 
having ultimately received congressional approval. 
Although members expressed concern about the use of the fast track procedures to consider the 
NAFTA implementing bill, no member formally challenged the bill’s eligibility for fast track 
consideration. To challenge the use of the fast track procedures in the consideration of the Korea

Agreement (Dec. 4, 2010) (characterizing the agreement in part as “a win for the strong alliance between the United 
States and South Korea, which for decades has ensured that the security that has maintained stability on the peninsula 
continues.... At a time in which there are increasing tensions on the Korean Peninsula, following the North’s 
unprovoked attack on the South Korean people, today we are showing that the defense alliance and partnership of the 
United States and South Korea is stronger than ever.”).

FTA implementing bill, a member must raise an objection. At that point, the bill’s eligibility for 
fast track consideration will be resolved by the chamber in which the objection was raised. If one 
of the chambers deems the Korea FTA implementing bill ineligible for fast track consideration 
under the Trade Act of 2002, then it will be considered under the regular procedures of that 
chamber. 
In addition, Congress retains substantial authority over whether to grant fast track consideration 
to the Korea FTA implementing bill. Each chamber may waive, suspend, or repeal fast track 
authority for legislation implementing the Korea FTA. Each chamber may also pass a resolution 
making the fast track procedures inapplicable to an implementing bill if the measure is deemed 
procedurally or substantively deficient under the terms of the Trade Act of 2002.
