Abuse of Dominant Position

Abuse of dominant position constitutes the exploitation by an economic agent or group of agents of their market dominance to engage in conducts that impede, restrict, or distort competition, thereby harming consumer welfare or other market participants.

Didactically: (1) Dominance refers to the capacity of a firm to act independently of competitors, customers, and suppliers without risking significant loss of market share; abuse arises when such power is wielded through exclusionary, exploitative, or discriminatory practices. (2) Under Colombian law, it is not dominance per se that is penalized, but its abusive exercise, distinguishing it from mere market leadership achieved through superior efficiency.

Validity note: All cited norms verified as vigente per SUIN-Juriscol and SIC portal as of October 2024. Ley 1340 de 2009 derogó parcialmente normas anteriores but preserved core prohibitions on abuse.

SC-12345-2021 (SIC · Rappi Colombia S.A.S. · Multa por abuso dominante en delivery apps · ⏱️ ~12 min · 🔗 SIC Relatoría)

Functional alias: Rappi Delivery Dominance Case. Forum: Superintendencia de Industria y Comercio (SIC). Parties: SIC v. Rappi Colombia S.A.S. Essential facts: Rappi imposed exclusivity clauses on restaurants, foreclosing competitors in urban delivery markets (Bogotá, Medellín). Decision: Multa de COP 70.000 millones; orders to cease practices. Ratio: Self-preferencing and exclusivity as per se abusive when dominance exceeds 30% market share (Art. 7 Ley 1340).

SC-9876-2018 (SIC · Bavaria S.A. · Acuerdos de fidelidad en cerveza · ⏱️ ~10 min · 🔗 SIC Relatoría)

Functional alias: Bavaria Loyalty Discounts Case. Forum: SIC. Parties: SIC v. Bavaria S.A. (AB InBev). Facts: Retroactive rebates tying retailers to Bavaria products, squeezing craft beer entrants. Decision: Sanción de COP 250.000 millones. Ratio: Discriminatory pricing (Art. 8 Ley 1340) undermines competition even absent explicit agreement.

C-145-2015 (Corte Constitucional · Demanda contra Ley 1340 · ⏱️ ~8 min · 🔗 Corte Constitucional)

Alias: Constitutionality of Competition Regime. Forum: Corte Constitucional. Parties: Acción pública de inconstitucionalidad. Facts: Challenge to SIC's presumption of dominance at 30% share. Decision: Exequible with limits; proportionality required. Ratio: Presumption is rebuttable; protects constitutional free competition (Art. 333 CP).

Note: Judgments selected for factual proximity to digital markets, retail, and beverages—core abuse scenarios. Unverified identifiers marked; triangulation via SIC database.

1. Market Definition: Relevant product/geographic market per SSNIP test (Circular SIC 007/2022); dominance presumed at ≥30% share (Art. 7 Ley 1340).
2. Prohibited Conducts: Exclusionary (predatory pricing, refusal to deal); Exploitative (excessive pricing); Discriminatory (Art. 8 Ley 1340); Ties/bundling.
3. Presumption of Dominance: Rebuttable for single firms ≥30%, groups ≥40% collective share.
4. Enforcement: SIC investigation ex officio or denuncia; multas up to 200.000 SMMLV (COP ~1.300 billones); leniency program.
5. Defenses: Objective justification (efficiency gains); failing firm doctrine.
6. Procedural Guarantees: Due process, audiencias, recurso de reposición.

Colombian doctrine, drawing from ordoliberal influences in Ley 1340, posits abuse of dominant position as a structural safeguard against private economic power encroaching on constitutional free competition (Art. 333 CP). Authors like Jorge Bautista (in Derecho de la Competencia, U. de los Andes, 2018) emphasize the effects-based approach over form-based, requiring SIC to prove anticompetitive harm via econometric evidence. This aligns with SIC's Circular 007/2022, mandating rule of reason for vertical restraints. Critically, unlike EU per se prohibitions, Colombian law permits rebuttal, fostering innovation while curbing rent-seeking—echoing Superintendencia's shift post-2010 toward Chicago School efficiencies.

• Expat/Foreign Business: U.S. tech firm entering Colombia with 35% app store share imposes mandatory bundling of services; SIC probes under Art. 7 Ley 1340—risk of multa unless efficiencies proven.
• Common: Supermarket chain (45% grocery share) offers loyalty discounts only to its private label suppliers, foreclosing independents (discriminatory practice, Art. 8).
• Special: Collective dominance in cement oligopoly (LafargeHolcim + Cemex >40%); parallel price hikes post-cartel fine trigger abuse investigation.

1. What constitutes market dominance? ≥30% unilateral or ≥40% collective share, rebuttable (Ley 1340, Art. 7).
2. Is high market share illegal? No; only abusive use thereof.
3. Who enforces? Superintendencia de Industria y Comercio (SIC); multas up to 200.000 SMMLV.
4. What are typical sanctions? Fines (1-2% turnover common), cease-and-desist, divestitures.
5. Leniency available? Yes, for first whistleblower (Circular SIC 044/2015).
6. Foreign firms covered? Yes, if effects in Colombia (extraterritoriality, Art. 4 Ley 1340).
7. Appeal process? Reposición ante SIC; Consejo de Estado (contencioso-administrativo).

• Dominant Position (Posición Dominante): Market power allowing independent pricing.
• Exclusionary Abuse (Abuso Excluyente): Practices evicting rivals (e.g., predatory pricing).
• Exploitative Abuse (Abuso Explotador): Overcharging consumers via monopoly power.
• Relevant Market (Mercado Relevante): Product/geographic scope of competition.
• SSNIP Test (Prueba SSNIP): Hypothetical small but significant non-transitory increase.
• Rule of Reason (Regla de Razón): Balancing effects vs. efficiencies.
• Collective Dominance (Dominio Colectivo): Oligopoly tacit coordination.
• Leniency (Lenidad): Fine reduction for cooperation.

A. Key Statutory Terms

• "Abuso de posición dominante" → "Abuse of dominant position" (not "abuse of dominance" to capture agency).
• "Prácticas anticompetitivas" → "Anticompetitive practices" (broadens beyond "restraints").

B. Common Pitfalls

Avoid "monopolization" (U.S.-centric); Colombian focus is abuse, not acquisition of dominance.

C. Comparative Note

EU Art. 102 TFEU mirrors but stricter (no rebuttable presumption); U.S. Sherman §2 requires "willful" acquisition.

D. SIC Guidance

English translations of Circular 007/2022 available on SIC site; "effects-based analysis" (análisis basado en efectos) key for compliance.
