Introduction

The case of Somerfield PLC v. Competition Commission ([2006] CAT 4) is a significant judgment in the realm of competition law within the United Kingdom. This case revolves around Somerfield plc's acquisition of 115 stores from Wm Morrison Supermarkets plc ("Morrisons") and the subsequent decision by the Competition Commission ("CC") to impose divestiture requirements to address potential anti-competitive outcomes.

The core issues pertained to whether the CC was legally justified in mandating Somerfield to divest specific acquired stores rather than allowing the firm discretion to choose which stores to divest. Additionally, the case scrutinized the CC’s exclusion of Limited Assortment Discounters ("LADs") from the list of approved divestees during the initial divestiture period.

The parties involved included Somerfield plc as the applicant seeking judicial review and the Competition Commission as the respondent enforcing divestiture to prevent a substantial lessening of competition ("SLC") in twelve local grocery markets.

Summary of the Judgment

The Competition Commission concluded that Somerfield's acquisition of 115 stores from Morrisons might lead to a substantial lessening of competition in twelve local grocery markets across Great Britain. To mitigate these anti-competitive effects, the CC ordered Somerfield to divest twelve of its stores to approved grocery retailers. Somerfield challenged this decision, arguing that the CC overstepped by restricting its divestiture options and improperly excluding LADs as potential purchasers.

The Competition Appeal Tribunal (CAT) undertook a judicial review as mandated by section 120 of the Enterprise Act 2002. After a comprehensive analysis, the Tribunal upheld the CC's decision, dismissing Somerfield's application for review. The Tribunal found that the CC acted within its legal powers and that its remedies were reasonable and adequately founded.

Analysis

Precedents Cited

The Tribunal referenced several key cases to determine the standard of review applicable to the CC's decision:

• Office of Fair Trading v. IBA Health [2004] EWCA Civ 142
• UniChem v. Office of Fair Trading [2005] CAT 8
• Tesco Stores Ltd v. Secretary of State for the Environment [1995] 1 WLR 759
• Commission v. Tetra Laval [2005] ECR I-987

These cases established that the Tribunal should apply a reasonableness test, assessing whether a decision-maker could have reasonably arrived at the decision in question. The margin of appreciation afforded to the CC was also a pivotal consideration, ensuring that the Tribunal does not interfere excessively with specialized bodies' expertise.

Legal Reasoning

The Tribunal's legal reasoning centered on the scope of the CC's statutory powers under the Enterprise Act 2002. It affirmed that the CC had the authority to impose divestiture remedies deemed necessary to restore competition within the affected markets. The CC's choice to prioritize divestiture of acquired stores over existing stores was deemed reasonable, given the need to ensure that the remedies would effectively mitigate the SLC identified.

Furthermore, the Tribunal validated the CC's exclusion of LADs from the initial set of approved divestees. The CC justified this exclusion based on comparative analyses of competitive constraints, product ranges, and customer diversion ratios, indicating that LADs did not pose a significant competitive threat comparable to other approved divestees.

The Tribunal also addressed Somerfield's challenge regarding the CC's reliance on factors such as store profitability, size, location, and condition in determining divestiture requirements. It concluded that these factors were relevant and appropriately considered by the CC in its remedies analysis.

Impact

This judgment reinforces the authority of competition bodies like the CC to impose structured divestiture orders to prevent anti-competitive outcomes resulting from mergers and acquisitions. It underscores the importance of a reasoned approach in remedy design, emphasizing that remedies must be effective, practical, and proportionate to the competition concerns identified.

For businesses, this case highlights the necessity of anticipating potential regulatory interventions in merger activities, particularly regarding asset divestitures. It also delineates the boundaries within which companies must operate when contesting competition authorities' decisions, stressing the need for substantial and well-founded arguments.

Complex Concepts Simplified

Substantial Lessening of Competition (SLC)

SLC refers to a significant reduction in competition within a market, which can lead to higher prices, reduced product choices, and lower service quality for consumers. Regulatory bodies monitor mergers and acquisitions to prevent SLC.

Divestiture Remedies

Divestiture remedies require a company involved in a merger or acquisition to sell off specific assets or business units. This is done to maintain competitive market conditions by ensuring that no single entity holds excessive market power.

Competitor Set

The competitor set comprises businesses that directly compete with each other in the same market. In remedy design, identifying the correct competitor set is crucial to ensure that divestiture targets are effective in restoring competition.

Margin of Appreciation

This legal doctrine allows specialized bodies (like the CC) a degree of discretion in their decision-making processes. It acknowledges that such bodies possess specialized knowledge and expertise that courts may not have, thereby limiting judicial interference unless decisions are unreasonable or unlawful.

Conclusion

The judgment in Somerfield PLC v. Competition Commission ([2006] CAT 4) solidifies the role of competition authorities in overseeing and remedying mergers to prevent SLCs. By upholding the CC's decision to mandate specific divestiture remedies and exclude LADs from initial divestiture options, the Tribunal affirmed the importance of tailored, evidence-based interventions in maintaining competitive markets.

This case serves as a precedent for future merger reviews, illustrating that competition bodies are empowered to impose precise remedies and that courts will generally defer to the expertise of these bodies unless decisions exceed legal boundaries or lack reasonable justification. Businesses engaged in mergers must thus prioritize compliance with competition laws and be prepared to substantiate their positions with robust evidence when challenging regulatory decisions.
