'''CURRENT STATUS: March 2026'''

''On January 16, 2026, the Surface Transportation Board unanimously rejected the Union Pacific–Norfolk Southern merger application as procedurally incomplete. On March 18, 2026, the Board issued Decision No. 13, denying a BNSF Railway discovery appeal on procedural grounds while also requiring the applicants to submit comprehensive traffic, infrastructure, and interchange data before refiling. Union Pacific and Norfolk Southern have formally notified the Board of their intention to file a revised application on April 30, 2026. The substantive review has not yet started. This article covers developments through March 2026.''

= Introduction =
The proposed merger between Union Pacific (UP) and Norfolk Southern (NS) has generated considerable discussion in industry publications and on social media, with much of the existing commentary consisting of opinion pieces or reactions. This analysis seeks to provide factual grounding, maintain neutrality, and explore fundamental concerns about what would become America’s first truly transcontinental railroad. The merger is now officially under review by the Surface Transportation Board (STB), which, under federal law, must determine whether the consolidation serves the public interest and affirmatively enhances competition, as required by the STB’s 2001 Major Merger Rules.

In July 2025, UP and NS announced their combination and submitted a formal application to the STB on December 19, 2025, accompanied by nearly 7,000 pages of documentation and more than 2,000 letters of support. The breadth of opposition that has developed, spanning the railroads’ own customers, major labor unions, bipartisan elected officials, passenger rail advocates, and competing carriers, makes this the most contested proposed rail merger since the consolidation wave of the 1990s.

= The Deal Structure =
The combined entity would operate under the Union Pacific name, led by current UP CEO Jim Vena. The transaction values Norfolk Southern at $320 per share, a 25% premium over pre-announcement trading levels, with a total enterprise value for NS of approximately $85 billion. A $2.5 billion breakup fee protects against regulatory or competitive obstacles. The resulting network would span over 50,000 route miles across 43 states, connecting more than 100 ports, making it, by financial measure, the largest rail merger in American history.

= Network Integration at Scale =
The merger’s central operational claim is the creation of America’s first single-line coast-to-coast rail network, eliminating interchange inefficiencies that currently fragment transcontinental long-haul service. The combined network would transform approximately 10,000 existing interline lanes into single-line service, eliminating an estimated 2,400 daily carload interchanges at gateways from Chicago to New Orleans. UP argues this will reduce costs by approximately 35% compared to interline moves, with single-line routing from Southern California to the Mid-Atlantic reducing transit times, improving asset utilization, and enhancing fuel efficiency through directional running capabilities.

High-density corridors present the greatest claimed opportunity for operational transformation. The Crescent Corridor connecting the Southeast to the Northeast, and the Sunset Route spanning the southern United States, could support expanded double and triple tracking, accommodating 75–100 daily trains compared to the 30–48 limit of current single-track segments, while reducing mixed freight-passenger congestion that constrains capacity. Chicago, the nation’s primary inland freight hub, may experience reduced congestion as transcontinental traffic bypasses traditional interchange bottlenecks, freeing capacity for regional and local service.

== The Block-Swapping Displacement Problem ==
The network efficiency claims warrant qualification on operational grounds. The merger proposes to “rationalize” interchange activity at Chicago and St. Louis, which currently function as massive classification ecosystems where trains are broken up, re-blocked, and handed off between carriers. These gateways also absorb variability in volume and timing, allowing each railroad to transfer traffic in the block size and configuration that works for onward movement.

Rationalizing these gateways does not eliminate block-swapping; rather, it simply relocates it. A physical constraint governs this displacement: the Meridian Speedway has strict train-length limits that prevent the longer planned UP–NS intermodal trains (12,000–15,000 feet) from traversing it intact. Trains must therefore be broken up and re-blocked at Shreveport, performing the same function that Chicago and St. Louis currently perform, in a different location.

Once Midwest gateways are rationalized, network geometry forces west-east traffic to be resized before entering the Speedway, South Texas traffic to be sorted and slotted into eastbound flows, and north-south and east-west flows to converge at Houston and Shreveport rather than Chicago or St. Louis. The block-swapping nodes shift to yards in Houston, Shreveport, and potentially Longview. For time-sensitive shippers, a mandatory re-blocking delay in Texas is operationally equivalent to the interchange friction the merger claims to eliminate. Shippers would pay single-line rates for a service that still requires the train to be broken apart, only in a different state.

== Structural Barriers to Truck Diversion ==
UP and NS state in their application that volume-growth projections are derived from an Oliver Wyman market study, which forms the analytical basis for the applicants’ forecast of shifting approximately 2 million annual truckloads from highway to rail. According to the application, roughly 75% of projected merger-related growth comes from truck conversion rather than diversion from competing railroads. The applicants further project that 105,000 carloads of merchandise traffic in the Mississippi watershed region would shift from road to rail as a result of reduced interchange friction.

Several structural barriers complicate these projections. Short-haul movements under 500 miles continue to face the same first-mile and last-mile drayage costs regardless of the merger’s single-line service improvements. The railroad intermodal share in lanes under 750 miles remains at approximately 11–13%, a figure that single-line service alone does not address. The watershed market growth UP forecasts depend on solving problems that interchange consolidation cannot remedy without additional terminal investment, particularly the absence of inland port infrastructure in the Mississippi Valley.

An emerging competitive factor compounds the truck diversion question. Autonomous vehicle platooning technologies began substantially reducing over-the-road operating costs in Sun Belt corridors in 2026, with some analyses projecting freight cost reductions of 29–47% in affected lanes. To the extent these projections materialize, the competitive ceiling that trucking rates set for rail pricing may compress, thereby affecting both the volume-diversion projections and the pricing power the merged entity anticipates.

Separately, the merger’s adoption of Precision Scheduled Railroading principles presents an internal tension. PSR has optimized for train length and fuel efficiency at the expense of network flexibility, the very quality the merger’s service improvement claims depend upon. Critics note that building longer trains while promising faster, more responsive service involves competing operational priorities that the application does not fully reconcile.

= Technological Modernization =
Scale enables technology deployment that transforms rail from a reactive freight transport mode to a proactive supply chain infrastructure. The merged network could accelerate the adoption of AI-driven logistics platforms for demand forecasting and dynamic asset allocation, smart yard automation to reduce dwell times, and digital cargo tracking systems providing real-time visibility across the continental network.

Zero-emission locomotive deployment becomes more viable as route miles expand and operational protocols are unified. The combined entity would possess the scale necessary to justify investment in hydrogen fuel cell and battery-electric technologies while maintaining service reliability during the transition period.

= Workforce and Governance =
Successful integration requires addressing labor concerns as competitive assets rather than cost variables. Proponents suggest a Rail Workforce Futures Initiative could attract talent in automation, systems engineering, and sustainability disciplines while providing retraining pathways for existing employees. However, as of March 2026, the labor landscape for the proposed $85 billion merger has shifted significantly, with several unions moving from initial neutrality or "measured skepticism" to active opposition.

The labor perspective on this merger is notable precisely because unions have no competitive stake in the outcome, as they represent workers at both railroads and would benefit from job protections regardless of the merger’s effect on freight competition. Yet, the unionized workforce is currently fractured. Support for the deal remains anchored by SMART-TD (the largest rail union), alongside the Brotherhood of Railway Carmen, the International Brotherhood of Boilermakers, the National Conference of Firemen and Oilers, and the United Supervisors Council of America. These organizations have signed "jobs-for-life" agreements with Union Pacific.

In contrast, a powerful bloc has mobilized against the deal. The Brotherhood of Locomotive Engineers and Trainmen (BLET) and the Brotherhood of Maintenance of Way Employees Division (BMWED), representing 53% of the combined UP-NS workforce, announced their opposition in December 2025 after a five-month investigation that included direct negotiations with UP CEO Jim Vena. They were joined in late December by the Brotherhood of Railroad Signalmen (BRS), the Transport Workers Union (TWU), and the American Train Dispatchers Association (ATDA). Meanwhile, groups such as the International Association of Machinists (District 19), the IBEW, and SMART-Mechanical remain undecided.

The rising opposition centers on three critical sticking points:

1.     '''"Hollow" Job Protections:''' Opponents claim that the agreements offered by UP contain significant loopholes regarding forced relocations and transfers between different crafts. BMWED President Tony Cardwell stated that job-protection agreements reached with other unions contain provisions that do not protect seniority, allow unlimited geographic transfers, and fail to address route spin-offs to short lines.

2.      '''Market Monopoly and Service Erosion:''' BLET National President Mark Wallace concluded that the merged carrier would make shipping by rail less attractive rather than more so. He predicts that the transcontinental railroad would pass off branch lines serving small towns, factories, and farms to short-line operators while running increasingly long trains on the mainline.

3.      '''Safety Risks and Cultural Clashes:''' The unions also raise safety concerns specific to UP’s operational practices. They note that Norfolk Southern has made measurable improvements since the February 2023 East Palestine derailment, including experimenting with the Federal Railroad Administration’s Confidential Close Call Reporting System, while UP has continued to resist comparable reforms.

The division within labor reflects a genuine disagreement about the adequacy of proposed protections and the long-term health of the rail ecosystem. Governance structures merit particular attention. A stakeholder transformation board incorporating labor representatives, shipper advocates, and community voices could institutionalize transparency and regional accountability, with annual stakeholder summits aligning investor priorities with broader ecosystem development rather than just the bottom line.

= Regulatory Environment =
The STB will conduct a detailed review under post-2001 rules requiring demonstrated public benefits and competitive safeguards, a framework that emerged directly from prior consolidation experiences. The UP-NS application is the first major merger to be evaluated under the heightened 2001 standards, which require applicants to affirmatively demonstrate that the merger would enhance competition, not merely preserve it.

== The January 2026 Rejection ==
On January 16, 2026, the STB unanimously rejected the merger application as incomplete. The decision was procedural rather than substantive, The board found the application deficient in three specific areas:

First, the applicants provided only static 2023 data rather than forward-looking projections of post-merger market share. This was particularly significant given UP’s claims of 15–26% traffic growth: the STB requires detailed data on future revenues and traffic volumes for major interregional corridors to assess whether the combined entity would exploit increased market power.

Second, Schedule 5.8 of the merger agreement, which defines what regulatory conditions would allow UP to walk away from the deal, was not included in the filing. Canadian National had specifically filed a motion to compel its disclosure. By withholding this document, the applicants prevented the public and the Board from evaluating what remedies the railroads are actually prepared to accept to mitigate competitive harm, including trackage rights, rate caps, and reciprocal switching mandates.

Third, the applicants treated the acquisition of the Terminal Railroad Association of St. Louis (TRRA) as a “minor” transaction. The STB reclassified it as “significant,” requiring more extensive documentation. The TRRA controls a pivotal interchange connecting east-west traffic across the Mississippi at St. Louis; its classification as significant reflects the Board’s concern that control of this gateway creates a strategic chokepoint on a critical corridor.

The STB emphasized that its decision “should not be read as an indication of how the Board might ultimately assess any future revised application.” Union Pacific and Norfolk Southern have formally notified the Board of their intent to file a revised application on April 30, 2026.

== Decision No. 13: Pre-Filing Data Mandates and the BNSF Discovery Appeal (March 18, 2026) ==
On March 18, 2026, the STB issued Decision No. 13, the most recent substantive action in the proceeding. The decision addressed two distinct matters: a discovery appeal by BNSF Railway, and the Board’s own requirements for data transparency prior to the April 30 refiling.

BNSF had sought to compel production of internal documents from the applicants, including materials provided to boards of directors, reports from financial advisors, and internal emails. The Board denied the appeal on procedural grounds: BNSF had filed outside the 10-day deadline prescribed by 49 C.F.R. § 1115.1(c) for appeals of interlocutory Administrative Law Judge rulings. The ALJ’s order was served on February 11; BNSF did not appeal until February 23. The Board did not rule on the merits of the discovery request. The proceeding itself was not dismissed and remains active.

Despite the procedural ruling in the applicants’ favor on the BNSF matter, the Board simultaneously imposed its own pre-filing data requirements. Before the April 30 revised application may be submitted, UP and NS must produce three categories of information to enable independent competitive analysis.

First, the applicants must provide 100% traffic tapes, including complete waybill records for a specified historical period, origin-to-destination routing, commodity codes, equipment types, and revenue figures, together with the technical metadata necessary for the Board’s Section of Economics to interpret the applicants’ internal data systems. This granular census of rail movements allows the Board to identify specific two-to-one shipping points, locations where a shipper would go from having two competitive rail options to only one. This is a critical issue that may be obscured by relying only on sampled data.

Second, the applicants must submit physical plant and operational infrastructure data, including GIS-compatible geospatial files representing the combined rail network, current track charts detailing grades, curvatures, and weight limits, station lists with SPLC codes, and operating timetables establishing baseline service frequency and velocity. This material allows the Board and intervenors to spatially identify parallel corridors and network redundancies independent of the applicants’ own characterizations.

Third, the applicants must disclose contractual and interline commitments, including their operating interests in the Peoria & Pekin Union Railway and the Terminal Railroad Association of St. Louis.  The STB also required applicants to disclose the interchange commitments that affect third-party shippers' access to neutral gateways. These contractual restrictions potentially constrain short-line railroads’ ability to hand off freight to competing Class I carriers.

Access to the mandated data by intervenors is governed by federal regulations and Protective Orders issued by the Board. Parties of record, including competing railroads, shipper trade associations, state transportation departments, and labor organizations, may access the material subject to confidentiality undertakings. Competing railroads requesting the 100% traffic tapes must agree to reciprocal disclosure of their own traffic data. The Board’s approach of requiring this information before the formal application clock begins ensures that the evidentiary record is complete from the outset of the substantive proceeding, rather than being assembled incrementally through discovery disputes after filing.

== Schedule 5.8 and Walk-Away Rights ==
The withheld Schedule 5.8 defines the specific level of regulatory interference UP is prepared to tolerate before the deal becomes financially or operationally unviable. Based on available information, three categories of regulatory conditions are understood to be under active discussion as potential deal-killers.

Forced reciprocal switching would allow any shipper captive to the merged network to pay a fee to have their freight moved to a competitor, such as BNSF or CSX. UP has signaled that if this mandate applies to a significant share of newly captured revenue, it would trigger the walk-away right. Divestiture of key interchanges, particularly around the St. Louis and Chicago gateways, could similarly trigger exit if losses from divested assets exceed a defined earnings threshold. Service performance bonds, meaning financial penalties for velocity drops during the integration period, represent a third category under discussion.

Opponents, including BNSF and the American Economic Liberties Project, argue that the existence of these walk-away rights reveals that the merger’s profitability is contingent on maintaining market dominance. Their argument is that if the merger genuinely produced the public benefits UP claims, such as shifting two million truckloads to rail, UP would be prepared to accept competitive guardrails as a condition of approval. The existence of Schedule 5.8 suggests the opposite.

== Reciprocal Switching ==
Separately from the merger review, the STB is considering expanded reciprocal switching regulations that would allow shippers to access a competing railroad even if they are physically served by only one carrier. This regulatory development intersects directly with the merger: if implemented broadly, it would partially offset the competitive harm of captive shipper consolidation. UP has characterized such a mandate as potentially “materially burdensome,” using the same threshold language found in Schedule 5.8, suggesting the company views broad reciprocal switching as a potential deal-terminating condition.

== The UP-SP Precedent ==
Multiple stakeholders cite the 1996 Union Pacific–Southern Pacific merger as a cautionary precedent. That merger, which also promised operational efficiencies and improved service, produced severe system congestion: initial delays in Houston created cascading disruptions across thousands of miles of track. By fall 1997, the system was effectively paralyzed. Train speeds dropped sharply and tens of thousands of rail cars were stranded on sidings for weeks or months. Chemical and agricultural shippers were particularly hard hit, with some Gulf Coast facilities forced to shut down due to raw material shortages. Shippers estimated losses of approximately $100 million per month; Union Pacific itself lost more than $1 billion and recorded three consecutive quarters of net losses.

The 2001 merger standards were a direct regulatory response to that experience. UP and NS argue they have learned from past integration failures and will implement the merger in phases. However, the STB’s rejection of the initial application, in part because it lacked sufficient detail on integration planning and service recovery protocols, suggests regulators continue to treat the UP-SP experience as an active rather than historical concern.

= Shipper Perspectives =
The most significant opposition comes from the railroads’ own customers. The Rail Customer Coalition (RCC), representing shippers responsible for more than half of all U.S. rail freight volume, has formally opposed the merger. The National Industrial Transportation League states it “opposes further consolidation in the freight rail industry based on past merger experiences resulting in higher rates and degraded service.” The cement industry and minerals producers have voiced similar concerns about reduced service options.

== The Rate Disparity Evidence ==
The American Chemistry Council (ACC), representing the third-largest rail customer segment and approximately 2.2 million carloads annually, has provided the most specific empirical evidence. According to ACC data, rail rates have increased 240% over the past fifteen years at facilities served by a single railroad, compared to just 24% at locations with competitive rail options. This tenfold disparity speaks directly to the central question of the merger review: whether efficiency gains from single-line service will flow to shippers or be captured as monopoly rents by the combined carrier.

The ACC argues that history demonstrates railroads price to the truck-competitive ceiling regardless of their actual costs once they hold monopoly power over a route. This directly challenges UP’s assertion that single-line service savings would be passed to shippers. ACC President Chris Jahn has characterized every major rail merger in recent history as ranging from a minor disruption to a major one for shippers.

== Volume Growth Skepticism ==
Multiple shipper groups have questioned UP’s projection of 12% volume growth within three years. According to STB statistics cited in shipper filings, the combined volumes of UP and NS have declined by 13% over the past decade. The juxtaposition is specific: applicants project near-term double-digit growth against a documented long-term trend of equivalent decline. The Rail Customer Coalition argues this projection strains credibility, absent a detailed explanation of what structural conditions the merger would change to reverse the trajectory.

== Committed Gateway Pricing Limitations ==
UP has proposed a Committed Gateway Pricing (CGP) mechanism intended to extend merger benefits to shippers who would not directly gain from single-line service. The program allows BNSF and CSX to market transcontinental service using formulaic rates through major interchanges at Chicago, St. Louis, Memphis, and New Orleans. UP describes the program as “purely additive,” providing an extra option without removing existing choices.

The dispute centers on actual eligibility. Estimates range from approximately 1% to 20% of customers, depending on the source and methodology. The program excludes intermodal traffic, automobiles, unit trains, and hazardous materials, significant carve-outs given the composition of the combined network’s traffic. TD Cowen analyst Jason Seidl reported that shippers in his firm’s roundtable found the CGP benefits unclear, particularly for carload and manifest freight, and noted limited adoption of comparable schemes on the I-5 corridor.

The more fundamental concern raised by the Rail Customer Coalition involves the temporal asymmetry of the arrangement: CGP commitments expire after a defined oversight period. Shippers are being asked to accept permanent structural consolidation in exchange for temporary pricing protections. Once protections lapse, captive shippers would have no mechanism to access competitive pricing short of additional regulatory intervention.

== Pricing Power and the Loss of Shipper Leverage ==
Under the current four-carrier Class I system, a shipper can often leverage a Western carrier against an Eastern partner to negotiate better interline rates for transcontinental moves. The merger eliminates that structural negotiating position for Inland Point Intermodal movements. If the merged entity captures efficiency gains as margin rather than passing them to customers, shippers would trade negotiating leverage for a faster transit time at a premium price they would have no competitive alternative to avoid.

= Competitive Dynamics and Market Structure =
The merger’s most significant secondary implication may be its catalytic effect on remaining Class I carriers. Industry analysts anticipate potential consolidation between CSX and BNSF Railway, which would create a duopolistic national structure with two transcontinental networks competing for long-haul traffic.

This competitive rebalancing presents both opportunities and risks. Balanced rivalry at scale could stimulate infrastructure investment, service-quality improvements, and technology adoption across both networks. Regional markets currently underserved might benefit from competitive pressure to expand coverage.

However, market simplification raises legitimate concerns about the concentration of pricing power and reduced shipper choice. BNSF CEO Katie Farmer has stated that the claimed public benefits of the merger appear to accrue primarily to shareholders rather than customers. Canadian National has noted that the merged entity would control more than 40% of the U.S. freight rail market, reducing rail transportation options while concentrating market power. CPKC has characterized the merger as unprecedented in scale with far-reaching risks to customers, employees, and broader supply chains.

It should be noted that competing railroads have obvious self-interest in opposing the merger, and their arguments should be evaluated accordingly. However, critics observe that the consistency of concerns across competitors with different business models and geographic footprints, combined with independent corroboration from shipper groups, labor unions, and elected officials, suggests concerns that are structural rather than purely competitive in origin.

Independent shortline railroads could face diminished access to Class I networks, while smaller shippers might encounter weakened negotiating positions regardless of the merger’s ultimate competitive dynamics.

= Political and Bipartisan Opposition =
Opposition to the merger has been notably bipartisan. A group of 18 U.S. Senators, including both Amy Klobuchar (D-MN) and John Hoeven (R-ND), urged the STB to apply rigorous scrutiny, warning that producers already face limited competitive options for rail service and that further consolidation could reduce routing flexibility, constrain network fluidity, and increase market power. Nine Republican state attorneys general and 54 Republican legislative leaders across 24 states have filed similar concerns, as have 47 U.S. House members and State Agriculture Secretaries from 10 states.

The agricultural dimension explains why opposition has not broken along predictable ideological lines. Agricultural shippers in Republican-leaning states depend on rail competition as heavily as chemical manufacturers in industrial corridors. Both constituencies face similar exposure to pricing and service consequences from captive shipper consolidation in the watershed region.

= Passenger Rail Implications =
The Rail Passengers Association has raised concerns about the merger’s implications for intercity passenger service. The combined UP-NS network would host 25 of 44 Amtrak state-supported and long-distance routes (57%), carrying more than 11.3 million passengers annually (63% of such ridership). UP and NS commit only to maintaining existing passenger service levels, a standard that preserves the status quo rather than enabling service growth.

The Association highlighted an apparent inconsistency in UP’s capacity claims: UP has previously stated that adding capacity sufficient to make the existing Sunset Limited a daily train would cost approximately $1 billion, yet the merger application simultaneously claims the network can absorb more than 100,000 additional freight carloads with modest investment. Critics note that railroads frequently characterize their tracks as “at capacity” when opposing new passenger service while claiming available capacity for new freight traffic when seeking merger approval.

= Community and Environmental Implications =
Track expansion and increased traffic volumes will generate local impacts requiring proactive management. Grade separation projects, noise mitigation measures, and environmental safeguards become essential components of network integration planning. Green infrastructure investments, including vegetated sound barriers and habitat preservation, can align operational needs with community expectations.

The merger’s environmental profile depends largely on the potential for a modal shift. If enhanced rail service attracts freight currently moving by truck, the consolidated network could reduce greenhouse gas emissions and highway congestion. However, increased train frequencies in existing corridors will require careful management of noise, safety, and community access concerns. The net environmental benefit is contingent on the truck diversion projections materializing, projections that shipper groups and the STB have both characterized as insufficiently documented.

= Policy Framework =
Rather than treating consolidation as an inevitable market force, policymakers and industry leaders have an opportunity to shape outcomes through structured stakeholder engagement and performance accountability. A coordinated policy framework incorporating environmental commitments, shared investment in corridor densification and rural access, and regulatory benchmarks for service quality would position rail infrastructure as a strategic economic development asset rather than purely private commercial enterprise.

The STB review process itself represents an opportunity to establish precedents for how future rail consolidation is evaluated and conditioned. The 2001 standards have never been applied to a merger of this scale; the procedural and substantive decisions the Board makes in this proceeding will define the regulatory framework for any subsequent consolidation among remaining Class I carriers.

= Looking Forward =
The UP-NS merger represents a strategic inflection point for North American rail transportation. For supply chain professionals, the consolidation offers potential benefits through improved service reliability, enhanced network reach, and technological capabilities, provided competitive alternatives are maintained, and consolidation serves broader economic interests rather than narrow financial objectives.

The breadth of opposition that has developed is analytically significant. When shippers representing more than half of rail freight volume, unions representing more than half of the combined workforce, and bipartisan groups of elected officials reach similar conclusions through independent analysis, the applicants face a credibility challenge that additional documentation alone may not resolve. The procedural deficiencies identified by the STB are fixable. Refiling does not address the substantive opposition.

Success will ultimately depend on execution across cultural integration, technology harmonization, stakeholder engagement, and performance measurement. When UP and NS refile with complete documentation on April 30, 2026, the evidentiary proceeding will provide an opportunity for rigorous examination of the competing claims summarized here. What is clear is that this would be the most consequential restructuring of American freight rail since the 1990s consolidation wave, and the STB’s 2001 standards require UP and NS to demonstrate that the merger would enhance competition, not merely preserve it.

The railroad industry stands at a crossroads between traditional operations and modern logistics requirements. Whether consolidation at this scale enhances or constrains rail’s role in 21st-century supply chains will be determined less by the deal’s structure than by the conditions attached to its approval and the discipline of its implementation.
