Comm2 Reviewer — Part IV-A: Competition Foundations, Scope, Market
PART 1 — SYLLABUS
1. Coverage Map
| § | Topic | Priority | The one rule you must state cold | Authority |
|---|---|---|---|---|
| 1 | Competition and importance, constitutional provisions, policies and rationale with the goals of competition law and the goals of the national economy | Core | Section 19 of Article XII makes competition the constitutional principle and commands the State to regulate or prohibit monopolies when the public interest so requires, while no combination in restraint of trade or unfair competition is ever allowed | 1987 Constitution Art. XII Secs. 1, 19; R.A. No. 10667 Sec. 2; Tatad v. Secretary of DOE (G.R. No. 124360, 1997) |
| 2 | Methods to deter anti-competitive conduct and the tools under the PCA with the three pillars | Core | Crime under Section 14(a) and 14(b) draws two to seven years with a P50,000,000 to P250,000,000 fine, other violations draw administrative fines after notice and hearing, and the three pillars are anti-competitive agreements, abuse of dominant position, and anti-competitive mergers and acquisitions | R.A. No. 10667 Secs. 14, 15, 17, 20, 29, 30, 35, 36, 37, 45 |
| 3 | Scope of the PCA, the relevant market rule with product and geographic markets, and the single economic unit rule | Core | The Act reaches every person or entity in Philippine trade, industry, and commerce plus foreign acts with direct, substantial, and reasonably foreseeable local effects, the relevant market joins product interchangeability with geographic homogeneity, and entities under common control that cannot act independently are never competitors | R.A. No. 10667 Secs. 3, 4(g), 4(i), 4(k), 14 last paragraph, 24, 25, 26, 27; Gios-Samar v. DOTC (G.R. No. 217158, 2019) |

4. Three-Pass Study Plan
| Pass | Time | What you do | Output |
|---|---|---|---|
| 1 | 40 percent | Frame controlling provisions: recite Art. XII Sec. 19, Art. XII Sec. 1, and Sections 2, 3, 4(k), 24, and 27 of the Act cold | One-page provision map from memory |

1. Competition and Importance; Constitutional Provisions; Policies and Rationale
“The State shall regulate or prohibit monopolies when the public interest so requires. No combinations in restraint of trade or unfair competition shall be allowed.”
“The goals of the national economy are a more equitable distribution of opportunities, income, and wealth; a sustained increase in the amount of goods and services produced by the nation for the benefit of the people; and an expanding productivity as the key to raising the quality of life for all, especially the underprivileged. The State shall promote industrialization and full employment based on sound agricultural development and agrarian reform, through industries that make full and efficient use of human and natural resources, and which are competitive in both domestic and foreign markets. However, the State shall protect Filipino enterprises against unfair foreign competition and trade practices. In the pursuit of these goals, all sectors of the economy and all regions of the country shall be given optimum opportunity to develop. Private enterprises, including corporations, cooperatives, and similar collective organizations, shall be encouraged to broaden the base of their ownership.”
“The efficiency of market competition as a mechanism for allocating goods and services is a generally accepted precept. The State recognizes that past measures undertaken to liberalize key sectors in the economy need to be reinforced by measures that safeguard competitive conditions. The State also recognizes that the provision of equal opportunities to all promotes entrepreneurial spirit, encourages private investments, facilitates technology development and transfer and enhances resource productivity. Unencumbered market competition also serves the interest of consumers by allowing them to exercise their right of choice over goods and services offered in the market. Pursuant to the constitutional goals for the national economy to attain a more equitable distribution of opportunities, income, and wealth; a sustained increase in the amount of goods and services produced by the nation for the benefit of the people; and an expanding productivity as the key to raising the quality of life for all, especially the underprivileged and the constitutional mandate that the State shall regulate or prohibit monopolies when the public interest so requires and that no combinations in restraint of trade or unfair competition shall be allowed, the State shall: (a) Enhance economic efficiency and promote free and fair competition in trade, industry and all commercial economic activities, as well as establish a National Competition Policy to be implemented by the Government of the Republic of the Philippines and all of its political agencies as a whole; (b) Prevent economic concentration which will control the production, distribution, trade, or industry that will unduly stifle competition, lessen, manipulate or constrict the discipline of free markets; and (c) Penalize all forms of anti-competitive agreements, abuse of dominant position and anti-competitive mergers and acquisitions, with the objective of protecting consumer welfare and advancing domestic and international trade and economic development.”
| Element or Requisite | Content |
|---|---|
| Competition and its importance | Competition allocates goods and services efficiently, disciplines liberalized sectors, spreads opportunity with investment and technology, and lets consumers choose freely among offers |
| Constitutional anchor | Section 19 of Article XII states the anti-trust principle of the Constitution and makes competition the underlying policy of the charter |
| Monopoly rule | The Constitution never bans every monopoly at once but commands regulation or prohibition when the public interest so requires |
| Combination rule | Every combination in restraint of trade and every unfair competition stands prohibited without need for a further showing of public interest |
| Goals of the national economy | Equitable distribution of opportunities, income, and wealth comes first, sustained increase of goods and services for the people comes second, and expanding productivity for the quality of life of all especially the underprivileged comes third |
| Goals of competition law | Economic efficiency with free and fair competition comes first, prevention of undue economic concentration comes second, and punishment of the three prohibited forms for consumer welfare comes third |
| Deregulation lesson | A deregulation law defeats itself when its tariff, inventory, and pricing rules build walls that only the entrenched oligopoly can climb |
| Old rule replaced | Article 186 of the Revised Penal Code once punished monopolies and combinations, and Section 55(a) of the Act now repeals it for later conduct |
Competition protects the process while the Constitution protects the nation, so the Act punishes conduct that closes markets and never punishes size alone. Goals of the economy state where the nation must go while goals of competition law state how markets must behave on the way there. A monopoly endures where public interest tolerates it while a combination in restraint of trade falls at once because the ban is absolute.
Case: Tatad v. Secretary of DOE, G.R. No. 124360, November 5, 1997
Facts: Congress passed the Downstream Oil Industry Deregulation Act of 1996 with a three percent tariff on imported crude and seven percent on imported refined products, an inventory burden on new players, and a predatory pricing rule, while only Petron, Shell, and Caltex held refineries and storage. Petitioners assailed the tariff differential, the inventory and pricing rules, and the executive order that ordered full deregulation on a ground outside the statute.
Issue: The issue was whether the tariff differential, the inventory requirement, and the predatory pricing rule erect unconstitutional barriers to entry under Section 19 of Article XII and whether the whole deregulation law must fall with them.
Held: The Court held the whole law unconstitutional, because the three provisions favored the entrenched oligopoly and barred new entrants from a truly competitive market, the offending parts so permeated the statute that Congress could not have passed it without them, and the executive had rewritten the deregulation standards by adding the depletion of the stabilization fund.
Doctrine: Section 19 of Article XII is anti-trust in history and in spirit and makes competition its underlying principle. Laws that barricade entry into an oligopoly market must fall. Offending provisions that permeate the essence of a statute void the whole law despite a separability clause.
Q: Congress deregulates the cement industry but keeps a prior-import-volume rule that only the two incumbent importers can meet, and no newcomer can sell a bag without five years of import records. A newcomer assails the rule as an entry barrier. Will the challenge prosper.
A: Yes, because the rule entrenches the incumbents and shuts newcomers out of a supposedly open market. Section 19 of Article XII commands the State to regulate or prohibit monopolies as public interest requires and absolutely bans combinations in restraint of trade with unfair competition. The ruling in Tatad v. Secretary of DOE (G.R. No. 124360, 1997) struck down a deregulation law whose tariff, inventory, and pricing rules built walls only the oligopoly could climb. The prior-volume rule therefore falls as an unconstitutional barrier to a truly competitive market.
Q: A mayor claims that the Constitution bans every monopoly so the city may seize the only ice plant in town without regulation. The owner answers that the plant charges fair prices and serves all buyers. May the city skip regulation and proceed to seizure.
A: No, because the Constitution bans no monopoly per se and commands regulation or prohibition only when the public interest so requires. A lone plant that serves all buyers at fair prices holds a factual monopoly without a prohibited combination, so the State must first test the facts against the public interest standard. The ruling in Tatad v. Secretary of DOE (G.R. No. 124360, 1997) treats Section 19 as an anti-trust command against entry barriers and not as an automatic death sentence on every large firm, a reading confirmed in Gios-Samar v. DOTC (G.R. No. 217158, 2019). The city therefore regulates before it prohibits and seizes nothing without law and just compensation.
2. Methods to Deter Anti-competitive Conduct; Tools under the PCA
“An entity that enters into any anti-competitive agreement as covered by Chapter III, Section 14(a) and 14(b) under this Act shall, for each and every violation, be penalized by imprisonment from two (2) to seven (7) years, and a fine of not less than fifty million pesos (P50,000,000.00) but not more than two hundred fifty million pesos (P250,000,000.00). The penalty of imprisonment shall be imposed upon the responsible officers, and directors of the entity. When the entities involved are juridical persons, the penalty of imprisonment shall be imposed on its officers, directors, or employees holding managerial positions, who are knowingly and willfully responsible for such violation.”
“In any investigation under Chapter III, Sections 14 and 15, and Chapter IV, Sections 17 and 20 of this Act, after due notice and hearing, the Commission shall impose the following schedule of administrative fines on any entity found to have violated the said sections: First offense: Fine of up to one hundred million pesos (P100,000,000.00); Second offense: Fine of not less than one hundred million pesos (P100,000,000.00) but not more than two hundred fifty million pesos (P250,000,000.00). In fixing the amount of the fine, the Commission shall have regard to both the gravity and the duration of the violation.”
| Element or Requisite | Content |
|---|---|
| Criminal method | Section 14(a) and 14(b) agreements draw two to seven years with a P50,000,000 to P250,000,000 fine for each violation, imposed on knowing and willful officers, directors, and managerial employees |
| Administrative method | Sections 14, 15, 17, and 20 violations draw fines after notice and hearing up to P100,000,000 for the first offense and P100,000,000 to P250,000,000 for the second, scaled to gravity and duration |
| Enforcement aids | Refusal to obey a Commission order draws P50,000 to P2,000,000 per violation with daily accrual from the forty-fifth day, and knowingly false filings draw up to P1,000,000 |
| Private method | Any person directly injured may bring a separate and independent civil action after the Commission completes the preliminary inquiry under Section 31 |
| Leniency method | The first reporter before inquiry starts earns immunity on four conditions, and a later reporter earns leniency on three harder conditions with full and continuing cooperation always required |
| Nolo method | An accused entity may plead nolo contendere only up to arraignment and later only with court permission, and the plea never proves liability in the civil suit |
| Consent method | Binding rulings, show cause orders, and consent judgments let a willing entity comply, stop, pay within the fine range, compensate victims, and report compliance before any case is filed |
| Basic-necessities multiplier | Fines triple where the violation moves basic necessities and prime commodities under R.A. No. 7581 as amended |
| Prescription guard | Every action prescribes in five years from discovery for crimes and from accrual for administrative and civil cases |
| First pillar | Section 14 prohibits anti-competitive agreements among competitors with per se and effects-based rules |
| Second pillar | Section 15 prohibits abuse of dominant position through conduct that substantially prevents, restricts, or lessens competition |
| Third pillar | Sections 16 to 23 review mergers and acquisitions and prohibit those that substantially prevent, restrict, or lessen competition in the relevant market |
Crime punishes the cartel while the fine prices the violation, so the same agreement can send officers to prison and bill the entity at once. A private suit compensates the victim while leniency buys the evidence, so the State recovers money and truth together. Per se condemnation needs no market weighing while effects analysis weighs harm against efficiency, so the pillar invoked decides the proof required.
Q: All four refiners agree to fix pump prices and rotate winning bids for government fuel. The finance manager who signed the minutes seeks immunity and tells everything after the inquiry has started. The Department of Justice charges the presidents. Who goes to jail and what happens to the manager.
A: The knowing and willful presidents face two to seven years with a P50,000,000 to P250,000,000 fine each while the manager may earn leniency but never automatic immunity. Section 30 punishes every Section 14(a) and 14(b) agreement per violation on responsible officers, and price fixing with bid rotation sits per se prohibited so no efficiency defense saves it. Section 35 grants a late reporter leniency only as the first to come forward with full and continuing cooperation where conviction evidence is still lacking and fairness allows. The presidents therefore stand trial for the cartel while the manager keeps only a chance at leniency.
Q: A consumer group proves a flour mill abused its dominant position and asks the Commission for P80,000,000 on first offense plus damages for every baker overcharged. The mill argues one forum must choose one remedy. Must the Commission stop at the fine.
A: No, because the administrative fine and the private civil action answer different injuries and run on separate tracks. Section 29 lets the Commission fine up to P100,000,000 on first offense after notice and hearing with gravity and duration guiding the amount, and Section 45 lets every directly injured person sue separately after the preliminary inquiry closes. The mill pays the State for the violation and pays the bakers for their losses, with triple fines if flour counts as a basic necessity. The Commission therefore imposes the fine while the bakers pursue their own civil case.
3. Scope of the PCA; Relevant Market Rule; Single Economic Unit Rule
“This Act shall be enforceable against any person or entity engaged in any trade, industry and commerce in the Republic of the Philippines. It shall likewise be applicable to international trade having direct, substantial, and reasonably foreseeable effects in trade, industry, or commerce in the Republic of the Philippines, including those that result from acts done outside the Republic of the Philippines. This Act shall not apply to the combinations or activities of workers or employees nor to agreements or arrangements with their employers when such combinations, activities, agreements, or arrangements are designed solely to facilitate collective bargaining in respect of conditions of employment.”
“Relevant market refers to the market in which a particular good or service is sold and which is a combination of the relevant product market and the relevant geographic market, defined as follows: (1) A relevant product market comprises all those goods and/or services which are regarded as interchangeable or substitutable by the consumer or the customer, by reason of the goods and/or services’ characteristics, their prices and their intended use; and (2) The relevant geographic market comprises the area in which the entity concerned is involved in the supply and demand of goods and services, in which the conditions of competition are sufficiently homogenous and which can be distinguished from neighboring areas because the conditions of competition are different in those areas.”
“For purposes of determining the relevant market, the following factors, among others, affecting the substitutability among goods or services constituting such market and the geographic area delineating the boundaries of the market shall be considered: (a) The possibilities of substituting the goods or services in question, with others of domestic or foreign origin, considering the technological possibilities, extent to which substitutes are available to consumers and time required for such substitution; (b) The cost of distribution of the good or service, its raw materials, its supplements and substitutes from other areas and abroad, considering freight, insurance, import duties and non-tariff restrictions; the restrictions imposed by economic agents or by their associations; and the time required to supply the market from those areas; (c) The cost and probability of users or consumers seeking other markets; and (d) National, local or international restrictions which limit access by users or consumers to alternate sources of supply or the access of suppliers to alternate consumers.”
“Dominant position refers to a position of economic strength that an entity or entities hold which makes it capable of controlling the relevant market independently from any or a combination of the following: competitors, customers, suppliers, or consumers;”
“There shall be a rebuttable presumption of market dominant position if the market share of an entity in the relevant market is at least fifty percent (50%), unless a new market share threshold is determined by the Commission for that particular sector. The Commission shall not consider the acquiring, maintaining and increasing of market share through legitimate means not substantially preventing, restricting, or lessening competition in the market such as but not limited to having superior skills, rendering superior service, producing or distributing quality products, having business acumen, and the enjoyment and use of protected intellectual property rights as violative of this Act.”
“An entity that controls, is controlled by, or is under common control with another entity or entities, have common economic interests, and are not otherwise able to decide or act independently of each other, shall not be considered competitors for purposes of this section.”
| Element or Requisite | Content |
|---|---|
| Covered person | Every person, natural or juridical, sole proprietorship, partnership, combination, or association in any form, domestic or foreign, including government owned or controlled entities in economic activity |
| Covered commerce | Every trade, industry, and commerce inside the Republic without sector exception |
| Foreign reach | International trade with direct, substantial, and reasonably foreseeable effects on Philippine trade, industry, or commerce, even from acts done abroad |
| Labor exception | Combinations and activities of workers or employees with employer deals solely for collective bargaining on employment conditions |
| Relevant product market | All goods or services the consumer regards as interchangeable or substitutable by characteristics, prices, and intended use |
| Relevant geographic market | The area of supply and demand where competition conditions stay sufficiently homogenous and differ from neighboring areas |
| Substitution factor | Technological possibility, availability of substitutes to consumers, and time needed to switch |
| Distribution-cost factor | Freight, insurance, duties, non-tariff limits, private restrictions, and time to supply from other areas |
| Switching factor | Cost and probability of users seeking other markets |
| Access-limit factor | National, local, or international limits on alternate supply and alternate customers |
| Control test | Control is presumed past one-half of voting power, and exists at or below one-half through voting pacts, direction of policy, board appointment or removal, majority of board votes, asset ownership or use, or decisive-rights contracts |
| Dominance test | Share with unilateral price or output power, barriers to entry, rival strength, input access, customer switching power, recent conduct, and other Commission criteria |
| Fifty percent presumption | Fifty percent share presumes dominant position subject to rebuttal and to a new sector threshold the Commission may set |
| Legitimate-means shield | Superior skill, service, product, business acumen, and intellectual property never count as violations by themselves |
| Single economic unit | Commonly controlled entities with common interests that cannot decide or act independently are never competitors under Section 14 |
| Conduct determination | The Commission defines the market, measures actual or potential substantial harm against efficiency gains, looks forward and backward, balances enforcement against overdeterrence, and weighs all evidence including reasonable commercial purpose |
Scope asks who must obey while market asks where competition happens, so foreign conduct obeys where local effects land and sister firms escape where independence is gone. Product likeness asks what buyers swap while geographic homogeneity asks where sellers truly meet, so island freight can split one product into two markets. Dominance presumes power from share while abuse proves misuse from conduct, so fifty percent opens the inquiry and never closes it.
Case: Gios-Samar v. DOTC, G.R. No. 217158, March 12, 2019
Facts: The transport department bundled six regional airports into two bid bundles for thirty-year development, operation, and maintenance concessions under the build-operate-transfer law. A taxpayer group sued directly in the Supreme Court to stop the bidding and alleged monopoly, restraint of trade, dummy arrangements, and grave abuse of discretion without pleading market facts or impleaded corporate identities.
Issue: The issue was whether the bundling created a prohibited monopoly and combination in restraint of trade and whether the Court could decide those claims without trial-level proof of the relevant market and dominant position.
Held: The Court dismissed the petition, because constitutional and statutory monopoly claims need ultimate facts on the market, the position, and the abuse that only evidence can supply, an exclusive service concession is never a monopoly by itself, and direct resort to the Court fails where factual questions remain.
Doctrine: Hierarchy of courts binds even transcendental claims, and transcendental importance excuses standing defects but never supplies missing facts. The State punishes abuse of dominant position and never the position itself. Exclusivity inheres in a service concession and public bidding protects the public interest.
Q: Two shipping lines serve the same island route and charge identical fares. A new entrant proves passengers treat the two lines as fully swappable but proves freight from the rival port costs twice as much with twice the sailing time. The lines claim one national market while the entrant claims an island market. Which market controls.
A: The island market controls if competition conditions there stay homogenous and differ from the national picture. The relevant geographic market turns on where supply and demand truly meet with shared conditions, and Section 24 weighs distribution cost with time to supply and the cost and probability of users seeking other ports. Passenger swappability fixes the product market while island freight and sailing time split the geography. The Commission therefore defines the island as the relevant geographic market before testing dominance and abuse inside it.
2024 Bar Q: 3. Ernest Bicycle Corporation (EBC) and Max Speed Corporation (MSC) are the leading manufacturers and sellers of electric bicycles in the country. EBC and MSC offer their bestselling models at PHP 25,000.00 per unit. In 2023, Gryffin Pedals, Inc. (GPI) entered the market and sold electric bicycles with features similar to EBC and MSC’s bestselling models for only PHP 20,000.00. GPI has no physical stores and offers its products in digital marketplaces. After a year, GPI had 75% share of the market leaving EBC and MSC at 15% and 10% shares, respectively. EBC and MSC filed a complaint before the Philippine Competition Commission and alleged that GPI is fast monopolizing the electric bicycles market because of its dominant position. Will the complaint against GPI for violation of the competition laws prosper? Explain.
A: No, because a seventy-five percent share only presumes a dominant position while the Act punishes abuse of that position and never the position itself. Section 27 raises a rebuttable presumption of dominance at fifty percent share yet shields share gained through superior skill, service, product, and business acumen, and Section 15 condemns only conduct that substantially prevents, restricts, or lessens competition such as below-cost selling with the object of destroying rivals. GPI sells a similar bicycle twenty percent cheaper through an efficient no-store marketplace model, and nothing shows selling below cost to kill rivals, entry barriers, or exclusionary conditions rather than legitimate price rivalry that benefits consumers. The complaint therefore fails on dominance alone while EBC and MSC must still prove abusive conduct inside a properly defined relevant market.

| Sec. 27 dominance | Rebuttable at fifty percent share with legitimate-means shield for skill, service, product, acumen, and intellectual property |
| Sec. 14 last paragraph single unit | Common control with common interests and no independent decision means never competitors |

| Sec. 30 criminal penalty | Two to seven years with P50,000,000 to P250,000,000 per violation on knowing and willful officers |
| Sec. 46 limitation | Five years from discovery for crimes and from accrual for administrative and civil cases |
| Period or Threshold | Figure |
|---|---|
| Monopoly ban trigger | Public interest so requiring, never automatic |
| Dominance presumption | At least 50 percent of the relevant market |
| Control presumption | More than one-half of voting power |
| First-offense fine ceiling | P100,000,000 |
| Second-offense fine range | P100,000,000 to P250,000,000 |
| Criminal imprisonment | 2 to 7 years per violation |
| Criminal fine range | P50,000,000 to P250,000,000 |

| Limitation period | 5 years |
| Transitory cure period | 2 years from effectivity under Sec. 53 |
| Effectivity | 15 days from publication with no retroactive effect |
| Scope question | Answer |
|---|---|
| Who must obey | Every person or entity in any trade, industry, and commerce including government firms in economic activity |
| Does foreign conduct count | Yes where effects on Philippine commerce are direct, substantial, and reasonably foreseeable |
| Does a union deal count | No where the deal solely facilitates collective bargaining on employment conditions |
| Does size alone violate | No, since only abuse of position and prohibited agreements and mergers answer |
| Market question | Answer |
|---|---|
| What joins to form it | Product interchangeability with geographic homogeneity |
| What proves product likeness | Characteristics with prices with intended use |
| What proves one geography | Shared competition conditions that differ from neighboring areas |
| What four factors test it | Substitution with distribution cost with switching cost with access limits |
| Who are never competitors | Commonly controlled firms that cannot act independently |
| Deterrence question | Rule |
|---|---|
| Crime or fine for price fixing | Both, since Sec. 30 imprisons officers while Sec. 29 fines the entity |
| Who may seek damages | Every directly injured person after the preliminary inquiry closes |
| Who earns immunity | The first reporter before inquiry with prompt exit, candor, full cooperation, and no coercion or leadership |
| What plea limits civil use | Nolo contendere up to arraignment never proves civil liability |
| What settles without a case | Binding rulings with show cause with consent judgments before filing |
| Distinction question | Answer |
|---|---|
| Monopoly against prohibited monopoly | Holding power needs public-interest regulation while restraining trade or competing unfairly is banned at once |
| Economy goals against competition goals | The first states national ends while the second states market means |
| Per se against effects-based | The first condemns price and bid rigs without weighing while the second balances harm against efficiency |
| Dominance against abuse | The first presumes from fifty percent while the second proves from exclusionary conduct |
| Control against single unit | The first maps power over one firm while the second merges firms that never compete |
Exam Traps
- Competition is the constitutional principle while monopoly is not banned per se, so public interest always mediates prohibition.
- Combinations in restraint of trade fall at once while monopolies wait for the public-interest test.
- Economy goals name three ends while competition goals name three market means, and examiners swap them to test recall.
- Deregulation that builds entry walls defeats itself, so tariff, inventory, and pricing rules decide constitutionality.
- A separability clause never saves a statute whose lifeblood provisions are void, since permeation beats severance.
- Price fixing and bid rigging condemn per se while other agreements wait for effects weighing against efficiency gains.
- Crime needs Section 14(a) or 14(b) only, so abuse and merger cases never send officers to prison.
- Every fine needs prior notice and hearing, so ex parte punishment voids even a correct finding.
- Gravity with duration prices every fine, so short and light violations never draw the ceiling.
- Private suits wait for the preliminary inquiry to close, so a pending inquiry bars the independent action for now.
- Leniency rewards the first and candid reporter, so second comers and silent leaders earn nothing.
- Foreign acts answer locally only with direct, substantial, and reasonably foreseeable effects proved together.
- Labor bargaining stands outside the Act only where employment conditions are its sole object.
- Product likeness asks what buyers swap while geography asks where sellers meet, so freight can split one good into two markets.
- Control looks past one-half votes to pacts, policy direction, board power, assets, and decisive rights.
- Common control without independence ends rivalry, so sister firms never conspire with each other.
- Fifty percent presumes dominance but never proves abuse, so share opens the case that conduct must close.
- Skill, service, product, acumen, and intellectual property shield share, so efficiency never counts as abuse by itself.
- Exclusive concessions never equal monopolies, since bidding itself guards the public interest.
- Courts never find markets without evidence, so conclusions without ultimate facts state no cause of action.

Source and Verification Note
This reviewer reads the Part IV-A syllabus slice with the Chapter 15 headings for pages 1014 to 1031 from the TOC file against the controlling primary texts. The scanned Aquino textbook carries no text layer, so no textbook sentence is quoted here and every blockquote comes from primary law checked in this run. Article XII Sections 1 and 19 were checked against the Official Gazette Article XII page with the Supreme Court E-Library Article XII page. Sections 2, 3, 4, 14, 15, 24, 25, 26, 27, 29, and 30 of R.A. No. 10667 were checked against the full LawPhil Republic Act page with the Official Gazette Act page for the declaration of policy and approval date. Case doctrine comes from the Batch 3 digests for Tatad v. Secretary of DOE and Gios-Samar v. DOTC, with the Anglo-Fil Trading ruling as quoted inside the Gios-Samar decision on the LawPhil PDF. Syllabus numbers 73 and 74 duplicate numbers 67 and 68, and the Topic Mapping places both decisions in Chapter 14 free-competition doctrine at book page 967, so they are not re-digested in this Part IV-A file. The compiled 2016 to 2025 commercial-law questionnaire carries exactly one competition question, the 2024 electric-bicycle dominance problem, which is quoted verbatim above with its official September 8, 2024 paper attribution. Every other drill in this reviewer is drafted from the doctrine and labeled accordingly with no year assigned. The amendatory law is R.A. No. 10667, the Philippine Competition Act, approved July 21, 2015, which repeals Article 186 of the Revised Penal Code for later conduct with no retroactive effect. LawPhil page artifacts were normalized without changing substance, including a misread verb in Section 14(b)(1) which is not quoted, and peso figures use standard notation.
