Comm2 Reviewer — Part IV-B: Prohibited Conduct, Mergers
PART 1 — SYLLABUS
1. Coverage Map
| § | Topic | Priority | The one rule you must state cold | Authority |
|---|---|---|---|---|
| 1 | Anti-competitive agreements with horizontal per se rules, effects-based rules, vertical agreements, and Commission determination | Core | Price fixing and bid rigging among competitors are condemned per se with no weighing of harm against efficiency, every other agreement answers only after the Commission defines the relevant market and finds substantial harm that outweighs efficiency gains, and commonly controlled firms that cannot act independently are never competitors | R.A. No. 10667 Secs. 4(b), 4(c), 14, 26; Eastern Telecommunications v. ICC (G.R. No. 135992, 2004); Gios-Samar v. DOTC (G.R. No. 217158, 2019) |
| 2 | Abuse of dominant position with factors, statutory provisions, the rule, prohibited conducts, permissible price differentials, and non-abuse agreements | Core | Holding a dominant position is never punished by itself and only conduct that substantially prevents, restricts, or lessens competition answers, while socialized pricing, cost-based differentials, responses to rivals, market-driven changes, good-faith below-cost meeting of competition, efficiency gains shared with consumers, and superior product with business acumen never count as abuse | R.A. No. 10667 Secs. 15, 27; Tatad v. Secretary of DOE (G.R. No. 124360, 1997) |
| 3 | Mergers and acquisitions control with meanings, provisions, summary, anti-competitive mergers, creeping transactions, and the compulsory notification threshold | High | Parties that breach the notification thresholds shall not consummate for thirty days extendible to ninety days with deemed approval on expiry, jumping the gun voids the agreement and draws one to five percent of transaction value, only deals that substantially lessen competition in the relevant market are prohibited with efficiency and failing-firm exits, and successive transactions within one year between the same parties count as one | R.A. No. 10667 Secs. 4(a), 4(j), 16, 17, 18, 19, 20, 21, 22, 23; PCC threshold circulars with SOP P9,100,000,000 and SOT P3,800,000,000 effective March 1, 2026 |
2. Learning Objectives
- Recite Section 14(a) word for word and explain why price fixing and bid rigging need no market weighing.
- Sort any agreement into per se, effects-based horizontal, vertical, or exempt single-unit conduct with the controlling paragraph cited.
- Run the five-step Commission determination in Section 26 in order on any agreement or conduct facts.
- State the abuse rule cold: dominance is lawful, only abusive conduct that substantially lessens competition is prohibited, and efficiency shared with consumers saves conduct.
- List every prohibited conduct in Section 15(a) to 15(i) with the exact saving clause that belongs to each one.
- Distinguish predatory below-cost selling with destructive object from good-faith meeting of a rival price.
- Run the merger clock in order: notification, thirty days, further-information request, sixty-day extension, ninety-day cap, deemed approval, and the voidness plus fine for closing early.
- Draft a complete answer on agreements, abuse, or merger review under time.

4. Three-Pass Study Plan
| Pass | Time | What you do | Output |
|---|---|---|---|
| 1 | 40 percent | Frame controlling provisions: recite Sec. 14(a) and 14(b), Sec. 15 opening with provisos, and Secs. 17, 20, and 21 cold | One-page provision map from memory |
| 2 | 35 percent | Distinguish pairs: per se against effects-based, horizontal against vertical, dominance against abuse, predatory pricing against meeting competition, prohibited merger against exempt rescue, one deal against creeping slices | Distinction tables reproduced cold |
| 3 | 25 percent | Apply problems: one drafted problem per section under time | Three marked answers under time |
Why this order: the examiner grades provision-first answers, so the authority filter comes before doctrine. Then confusion pairs win marks because Part IV-B questions punish merged characterizations of condemnation rules, pricing defenses, and merger clocks.

PART 2 — BOOK + AUTHORITY REVIEWER
0. One-Page Outline
| # | Topic | Must-know: provision + elements |
|---|---|---|
| 1 | Anti-competitive agreements | Sec. 14(a) condemns price and bid rigs per se, Sec. 14(b) condemns output limits and market sharing on object or effect, Sec. 14(c) condemns all other substantially harmful agreements with an efficiency saving clause, commonly controlled firms never count as competitors, and Sec. 26 runs define market with harm weighing with forward look with overdeterrence balance with totality of evidence |
| 2 | Abuse of dominant position | Sec. 15 punishes only conduct that substantially prevents, restricts, or lessens competition through nine named conducts, dominance itself with legitimate share growth with shared efficiency gains stays lawful, and the four price differentials with franchise and IP agreements are expressly saved |
| 3 | Mergers and acquisitions control | Sec. 4(a) with 4(j) define the deals, Sec. 17 bars closing for thirty days extendible to ninety with deemed approval and punishes gun-jumping with voidness plus one to five percent, Sec. 20 prohibits only substantially harmful deals, Sec. 21 saves efficient and failing-firm deals with the burden on the parties, and one-year successive slices count as one with thresholds set by the Commission |
Framing questions for every problem: which condemnation track applies (per se, effects, or abuse). Which paragraph supplies each element. Which saving clause or exemption defeats the charge. What clock, remedy, or forum closes the case.
Mnemonic for the three sections: Fix, Bully, Buy (F-B-B). Numbers: 14 (agreements), 26 (determination), 15 (abuse), 27 with 50 (dominance), 17 with 30-60-90 (notification clock), 19 (threshold regulation), 20 (prohibited deals), 21 (exemptions), 22 (burden), 23 (finality).
1. Anti-competitive Agreements
“(a) The following agreements, between or among competitors, are per se prohibited: (1) Restricting competition as to price, or components thereof, or other terms of trade; (2) Fixing price at an auction or in any form of bidding including cover bidding, bid suppression, bid rotation and market allocation and other analogous practices of bid manipulation;”
“(b) The following agreements, between or among competitors which have the object or effect of substantially preventing, restricting or lessening competition shall be prohibited: (1) Setting, limiting, or controlling production, markets, technical development, or investment; (2) Dividing or sharing the market, whether by volume of sales or purchases, territory, type of goods or services, buyers or sellers or any other means;”
“(c) Agreements other than those specified in (a) and (b) of this section which have the object or effect of substantially preventing, restricting or lessening competition shall also be prohibited: Provided, Those which contribute to improving the production or distribution of goods and services or to promoting technical or economic progress, while allowing consumers a fair share of the resulting benefits, may not necessarily be deemed a violation 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.”
“Agreement refers to any type or form of contract, arrangement, understanding, collective recommendation, or concerted action, whether formal or informal, explicit or tacit, written or oral;”
“In determining whether anti-competitive agreement or conduct has been committed, the Commission shall: (a) Define the relevant market allegedly affected by the anti-competitive agreement or conduct, following the principles laid out in Section 24 of this Chapter; (b) Determine if there is actual or potential adverse impact on competition in the relevant market caused by the alleged agreement or conduct, and if such impact is substantial and outweighs the actual or potential efficiency gains that result from the agreement or conduct; (c) Adopt a broad and forward-looking perspective, recognizing future market developments, any overriding need to make the goods or services available to consumers, the requirements of large investments in infrastructure, the requirements of law, and the need of our economy to respond to international competition, but also taking account of past behavior of the parties involved and prevailing market conditions; (d) Balance the need to ensure that competition is not prevented or substantially restricted and the risk that competition efficiency, productivity, innovation, or development of priority areas or industries in the general interest of the country may be deterred by overzealous or undue intervention; and (e) Assess the totality of evidence on whether it is more likely than not that the entity has engaged in anti-competitive agreement or conduct including whether the entity’s conduct was done with a reasonable commercial purpose such as but not limited to phasing out of a product or closure of a business, or as a reasonable commercial response to the market entry or conduct of a competitor.”
| Element or Requisite | Content |
|---|---|
| Concept of agreement | Every contract, arrangement, understanding, collective recommendation, or concerted action counts, whether formal or informal, explicit or tacit, written or oral, so a handshake and a chat message bind like a signed pact |
| Horizontal per se | Price restrictions with price or bid fixing among competitors are condemned without proof of market, harm, or intent to excuse, and cover bidding with suppression with rotation with allocation counts as bid manipulation |
| Effects-based horizontal | Output, market, technology, and investment controls with market division by volume, territory, goods, buyers, sellers, or any other means answer only where object or effect substantially lessens competition |
| Vertical agreements | Supplier-to-buyer restraints fall under Section 14(c) and answer on object or effect, with efficiency that shares benefits with consumers as the saving clause |
| Single economic unit | Commonly controlled entities with common interests that cannot decide or act independently are never competitors, so sister firms never conspire with each other |
| Commission determination | The Commission defines the market, weighs substantial harm against efficiency gains, looks forward and backward, balances enforcement against overdeterrence, and decides on the totality of evidence with reasonable commercial purpose in view |
| Criminal reach | Only Section 14(a) and 14(b) agreements draw two to seven years with P50,000,000 to P250,000,000 per violation on knowing and willful officers |
Per se condemnation needs no market weighing while effects analysis weighs harm against efficiency, so the paragraph invoked decides the proof required. Horizontal agreements bind rivals at one level while vertical agreements bind sellers to buyers across levels, so the parties map fixes the track. Common control ends rivalry while separate control starts it, so sister firms never trigger Section 14 among themselves.
Case: Eastern Telecommunications v. ICC, G.R. No. 135992, July 23, 2004
Facts: The telecoms commission granted a provisional authority to a second carrier over Manila and Navotas although a prior carrier held a subsisting authority there. The first carrier claimed a vested right to its service areas and sought to block the entrant.
Issue: The issue was whether the prior carrier held an exclusive right that barred a second authority and whether healthy competition allowed the new entry.
Held: The Court sustained the second grant, because no franchise is exclusive under the Constitution, the old one-carrier service area scheme had given way to healthy competition, and a prior operator holds no right to be shielded from a qualified rival.
Doctrine: Entry of a qualified rival never takes property from the incumbent. Regulators decide technical and financial fitness with deference from courts. Competition among carriers serves the public through better service.
Case: Gios-Samar v. DOTC, G.R. No. 217158, March 12, 2019
Facts: A taxpayer group asked the Supreme Court to stop the bundling of six regional airports into two bid bundles and alleged monopoly, restraint of trade, and dummy arrangements. The petition pleaded legal conclusions without market facts, corporate identities, or stockholding details.
Issue: The issue was whether conclusions of monopoly and restraint suffice without ultimate facts on the relevant market, the dominant position, and the abuse.
Held: The Court dismissed the petition, because monopoly and restraint claims need ultimate facts on the market, the position, and the abuse that only evidence can supply, and exclusivity in a concession never equals monopoly by itself.
Doctrine: Conclusions never state a cause of action without ultimate facts. Dominance needs proof of market share with power over price or supply. Abuse needs proof of exclusionary conduct and not of size alone. (Full digest in Part IV-A §3.)
Q: All four refiners agree in a group chat to fix pump prices and rotate winning bids for municipal fuel. The finance manager who typed the minutes claims the deal was oral and informal so no agreement exists. Is the cartel per se prohibited.
A: Yes, because price fixing with bid rotation among competitors is condemned per se with no weighing of harm against efficiency. Section 14(a) punishes restricting competition as to price and fixing price in any bidding with cover bidding, suppression, rotation, allocation, and analogous manipulation, while agreement covers every tacit, oral, and informal concerted action. The ruling in Gios-Samar v. DOTC (G.R. No. 217158, 2019) still requires the Commission to define the market and weigh effects for other agreements, but per se cartels need no such weighing. The chat therefore proves the agreement and the managers face prosecution with the entity fined.
Q: Two cement makers divide towns by buyer with one taking north distributors and the other taking south distributors. A new entrant proves the division, and the makers answer that no price was ever fixed. Must the Commission still weigh effects before condemning the pact.
A: Yes, because market division by buyers answers under Section 14(b) only where object or effect substantially lessens competition. Section 14(b)(2) prohibits dividing or sharing the market by volume, territory, goods, buyers, sellers, or any other means with that substantial-harm test, and Section 26 requires market definition with harm weighed against efficiency gains. The ruling in Eastern Telecommunications v. ICC (G.R. No. 135992, 2004) favors open rivalry over carved-up territories, since no operator holds a vested right to a fenced market. The Commission therefore defines the cement market, tests substantial harm against any proven efficiency, and condemns the pact where harm prevails.
2. Abuse of Dominant Position
“It shall be prohibited for one or more entities to abuse their dominant position by engaging in conduct that would substantially prevent, restrict or lessen competition: (a) Selling goods or services below cost with the object of driving competition out of the relevant market: Provided, That in the Commission’s evaluation of this fact, it shall consider whether the entity or entities have no such object and the price established was in good faith to meet or compete with the lower price of a competitor in the same market selling the same or comparable product or service of like quality; (b) Imposing barriers to entry or committing acts that prevent competitors from growing within the market in an anti-competitive manner except those that develop in the market as a result of or arising from a superior product or process, business acumen, or legal rights or laws; (c) Making a transaction subject to acceptance by the other parties of other obligations which, by their nature or according to commercial usage, have no connection with the transaction; (d) Setting prices or other terms or conditions that discriminate unreasonably between customers or sellers of the same goods or services, where such customers or sellers are contemporaneously trading on similar terms and conditions, where the effect may be to lessen competition substantially: Provided, That the following shall be considered permissible price differentials: (1) Socialized pricing for the less fortunate sector of the economy; (2) Price differential which reasonably or approximately reflect differences in the cost of manufacture, sale, or delivery resulting from differing methods, technical conditions, or quantities in which the goods or services are sold or delivered to the buyers or sellers; (3) Price differential or terms of sale offered in response to the competitive price of payments, services or changes in the facilities furnished by a competitor; and (4) Price changes in response to changing market conditions, marketability of goods or services, or volume; (e) Imposing restrictions on the lease or contract for sale or trade of goods or services concerning where, to whom, or in what forms goods or services may be sold or traded, such as fixing prices, giving preferential discounts or rebate upon such price, or imposing conditions not to deal with competing entities, where the object or effect of the restrictions is to prevent, restrict or lessen competition substantially: Provided, That nothing contained in this Act shall prohibit or render unlawful: (1) Permissible franchising, licensing, exclusive merchandising or exclusive distributorship agreements such as those which give each party the right to unilaterally terminate the agreement; or (2) Agreements protecting intellectual property rights, confidential information, or trade secrets; (f) Making supply of particular goods or services dependent upon the purchase of other goods or services from the supplier which have no direct connection with the main goods or services to be supplied; (g) Directly or indirectly imposing unfairly low purchase prices for the goods or services of, among others, marginalized agricultural producers, fisherfolk, micro-, small-, medium-scale enterprises, and other marginalized service providers and producers; (h) Directly or indirectly imposing unfair purchase or selling price on their competitors, customers, suppliers or consumers, provided that prices that develop in the market as a result of or due to a superior product or process, business acumen or legal rights or laws shall not be considered unfair prices; and (i) Limiting production, markets or technical development to the prejudice of consumers, provided that limitations that develop in the market as a result of or due to a superior product or process, business acumen or legal rights or laws shall not be a violation of this Act: Provided, That nothing in this Act shall be construed or interpreted as a prohibition on having a dominant position in a relevant market or on acquiring, maintaining and increasing market share through legitimate means that do not substantially prevent, restrict or lessen competition: Provided, further, That any conduct which contributes to improving production or distribution of goods or services within the relevant market, or promoting technical and economic progress while allowing consumers a fair share of the resulting benefit may not necessarily be considered an abuse of dominant position: Provided, finally, That the foregoing shall not constrain the Commission or the relevant regulator from pursuing measures that would promote fair competition or more competition as provided in this Act.”
| Element or Requisite | Content |
|---|---|
| The rule | Dominance is lawful and only abusive conduct that substantially prevents, restricts, or lessens competition is prohibited, so size opens the inquiry that conduct must close |
| Dominance factors | Share with unilateral price or supply power, entry barriers with foreseeable change, rival strength, input access, customer switching power, recent conduct, and other Commission criteria fix the position |
| Fifty percent presumption | Fifty percent share raises a rebuttable presumption of dominance subject to a new sector threshold, while superior skill, service, product, acumen, and intellectual property never count as violations |
| Predatory pricing | Below-cost selling with the object of destroying rivals abuses, while good-faith matching of a rival price for the same or comparable product never abuses |
| Entry barriers | Blocking entry or stunting rivals anti-competitively abuses, while walls built by superior product, process, acumen, or law never abuse, following Tatad v. Secretary of DOE (G.R. No. 124360, 1997) on unconstitutional barriers |
| Tying and conditions | Forcing unrelated obligations, tying unrelated purchases to supply, and exclusivity conditions that substantially lessen competition all abuse |
| Discrimination | Unreasonable price or term gaps among contemporaneous traders on similar terms abuse where competition substantially lessens, while the four differentials in Section 15(d) stay permissible |
| Non-abuse agreements | Unilaterally terminable franchise, license, and exclusive distributorship pacts with intellectual property and trade-secret protections never violate by themselves |
| Exploitative pricing | Unfairly low buying prices on marginalized producers with unfair selling or buying prices on rivals, customers, suppliers, or consumers abuse, while prices earned by superiority, acumen, or law never count as unfair |
| Output limits | Capping production, markets, or technical development to consumer prejudice abuses, while limits earned by superiority, acumen, or law never violate |
| Efficiency saving | Conduct that improves production or distribution or promotes technical and economic progress with a fair consumer share may not count as abuse |
Abuse punishes conduct while dominance describes power, so fifty percent presumes the position that exclusionary acts must still prove. Predation kills rivals while matching answers them, so object separates the crime of pricing from the virtue of competing. Tying forces extras while franchising frees exits, so unilateral termination saves the distributorship that coercion condemns.
Q: A dominant flour mill sells below cost for six months with internal memos targeting the death of a new rival mill. A second dominant mill only matches the first mill price in good faith for comparable flour. Which mill abuses its position.
A: The first mill abuses while the second stays lawful, because object separates predation from competition. Section 15(a) condemns below-cost selling with the object of driving competition out of the relevant market yet expressly saves prices set in good faith to meet a rival price for the same or comparable product of like quality. The memos prove destructive object for the first mill while good-faith matching shields the second, and dominance alone condemns neither without abusive conduct. The Commission therefore pursues the predator and clears the matcher.
Q: A dominant bottler charges provincial dealers a higher price than Manila dealers for identical drinks on identical terms, and the gap tracks no cost, volume, or rival-price difference. The bottler answers that price gaps are normal business. Is the differential permissible.
A: No, because unreasonable discrimination among contemporaneous traders on similar terms abuses where competition substantially lessens. Section 15(d) condemns such gaps while saving only four differentials, namely socialized pricing for the less fortunate, cost-reflecting differences, responses to rival prices or facilities, and changes driven by market conditions, marketability, or volume. No saving clause fits a gap that tracks no cost, volume, or rivalry, and the effect on provincial dealers is exclusion from fair rivalry. The differential therefore falls outside every permissible class and answers as abuse.
3. Mergers and Acquisitions Control
“Acquisition refers to the purchase of securities or assets, through contract or other means, for the purpose of obtaining control by: (1) One (1) entity of the whole or part of another; (2) Two (2) or more entities over another; or (3) One (1) or more entities over one (1) or more entities;”
“Merger refers to the joining of two (2) or more entities into an existing entity or to form a new entity;”
“Parties to the merger or acquisition agreement referred to in the preceding section wherein the value of the transaction exceeds one billion pesos (P1,000,000,000.00) are prohibited from consummating their agreement until thirty (30) days after providing notification to the Commission in the form and containing the information specified in the regulations issued by the Commission: Provided, That the Commission shall promulgate other criteria, such as increased market share in the relevant market in excess of minimum thresholds, that may be applied specifically to a sector, or across some or all sectors, in determining whether parties to a merger or acquisition shall notify the Commission under this Chapter.”
“An agreement consummated in violation of this requirement to notify the Commission shall be considered void and subject the parties to an administrative fine of one percent (1%) to five percent (5%) of the value of the transaction.”
“Should the Commission deem it necessary, it may request further information that are reasonably necessary and directly relevant to the prohibition under Section 20 hereof from the parties to the agreement before the expiration of the thirty (30)-day period referred. The issuance of such a request has the effect of extending the period within which the agreement may not be consummated for an additional sixty (60) days, beginning on the day after the request for information is received by the parties: Provided, That, in no case shall the total period for review by the Commission of the subject agreement exceed ninety (90) days from initial notification by the parties.”
“When the above periods have expired and no decision has been promulgated for whatever reason, the merger or acquisition shall be deemed approved and the parties may proceed to implement or consummate it.”
“Merger or acquisition agreements that substantially prevent, restrict or lessen competition in the relevant market or in the market for goods or services as may be determined by the Commission shall be prohibited.”
“Merger or acquisition agreement prohibited under Section 20 of this Chapter may, nonetheless, be exempt from prohibition by the Commission when the parties establish either of the following: (a) The concentration has brought about or is likely to bring about gains in efficiencies that are greater than the effects of any limitation on competition that result or likely to result from the merger or acquisition agreement; or (b) A party to the merger or acquisition agreement is faced with actual or imminent financial failure, and the agreement represents the least anti-competitive arrangement among the known alternative uses for the failing entity’s assets:”
“The burden of proof under Section 21 lies with the parties seeking the exemption. A party seeking to rely on the exemption specified in Section 21(a) must demonstrate that if the agreement were not implemented, significant efficiency gains would not be realized.”
| Element or Requisite | Content |
|---|---|
| Meaning of merger | The joining of two or more entities into an existing entity or into a new entity, covering statutory mergers and consolidations with joint ventures that combine or change control |
| Meaning of acquisition | The purchase of securities or assets by contract or other means to obtain control by one over another, by two or more over another, or by one or more over one or more, covering share and asset deals |
| Review power | The Commission reviews mergers and acquisitions on factors it deems relevant and may prohibit, conditionally clear, or consensually condition any deal that fails Section 20 and earns no Section 21 exemption |
| Notification trigger | Breach of the operative thresholds compels notification in the form the regulations require, starting from the statutory P1,000,000,000.00 base as adjusted by the Commission under Section 19 |
| Current thresholds | Size of Party P9,100,000,000 with Size of Transaction P3,800,000,000 effective March 1, 2026, replacing P8,500,000,000 with P3,500,000,000 effective March 2025, with both tests adjusted periodically |
| Waiting clock | Thirty days from notification with no closing, plus sixty more days from the day after a further-information request arrives, capped at ninety days from initial notification, with deemed approval where no decision issues |
| Gun-jumping | Closing without the required notice voids the agreement and draws an administrative fine of one percent to five percent of transaction value |
| Anti-competitive merger | Any deal that substantially prevents, restricts, or lessens competition in the relevant market stands prohibited as the Commission determines it |
| Efficiency exemption | Concentrations whose proven efficiency gains beat their competitive harm earn exemption, with the parties proving that the gains would not happen without the deal |
| Failing-firm exemption | Deals rescuing an actually or imminently failing party earn exemption only as the least anti-competitive arrangement among known alternative uses of its assets |
| Burden and finality | The parties carry the burden on every exemption claim, while a favorable ruling stands final unless won by fraud or false material information |
| Creeping transactions | Successive transactions or part-acquisitions within one year between the same parties or their controlled or commonly controlled entities count as one transaction for notification |
Review clears deals while prohibition kills them, so notification buys the Commission time that closing early forfeits. Efficiency saves mergers while failure excuses them, so gains must beat harm and rescue must be the gentlest option. Slices dodge notice while aggregation catches them, so the one-year rule treats creeping steps as a single deal.
Q: Two beverage giants breach both operative thresholds and sign on June 1 with notice filed the same day. They close on June 11 before any decision. The giants claim the ten-day sprint harmed no one. What is the status of the closing.
A: The closing is void and both giants face an administrative fine of one percent to five percent of the transaction value. Section 17 bars consummation until thirty days after notification and voids any agreement closed in breach, with the fine keyed to transaction value rather than to proven harm. The ten-day sprint therefore jumps the gun even if the market felt nothing yet, and the Commission may still review the deal on the merits. The parties must re-notify and wait out the clock with penalties paid.
Q: A buyer takes control of a rival in four monthly slices within one year, with each slice below threshold but all four combined above it. The buyer files nothing and claims each slice stands alone. Must the buyer have notified.
A: Yes, because successive acquisitions within one year between the same parties count as one transaction for notification. The creeping-transaction rule treats slices and part-acquisitions inside the one-year window as a single deal, reckoned from the binding preliminary agreement where one exists and otherwise from the last step that pushes the total past the thresholds. The buyer therefore owed notice once the combined slices breached both tests, and closing the last slice without notice voids it with a one to five percent fine. Splitting one takeover into small steps never defeats compulsory notification.

| Agreement question | Answer |
|---|---|
| Which agreements need no weighing | Price restrictions with price and bid fixing among competitors under Sec. 14(a) |
| Which agreements need object-or-effect proof | Output controls with market division under Sec. 14(b) with all others under Sec. 14(c) |

| Which agreements send officers to prison | Only Sec. 14(a) and 14(b) agreements under Sec. 30 |
| Abuse question | Rule |
|---|---|
| Is dominance itself illegal | No, since only abusive conduct that substantially lessens competition answers |
| Is below-cost selling always abuse | No, since good-faith matching of a rival price is expressly saved |
| Are entry barriers always abuse | No, since walls built by superior product, acumen, or law are expressly saved |
| Which price gaps survive | Socialized pricing with cost-based gaps with rival responses with market-driven changes |

| What punishes early closing | Voidness with one to five percent of transaction value |
| Which deals are prohibited | Only those substantially lessening competition in the relevant market under Sec. 20 |
| Which deals are exempt | Efficient concentrations with failing-firm rescues as the least restrictive option |
| Who proves the exemption | The parties seeking it under Sec. 22 |
| How are creeping slices treated | Successive deals within one year count as one transaction |
| Distinction question | Answer |
|---|---|
| Per se against effects-based | The first condemns price and bid rigs without weighing while the second weighs harm against efficiency |
| Horizontal against vertical | The first binds rivals at one level while the second binds sellers to buyers across levels |
| Dominance against abuse | The first presumes from fifty percent while the second proves from exclusionary conduct |
| Predation against matching | The first carries destructive object while the second answers a rival price in good faith |
| Prohibited merger against exempt rescue | The first substantially lessens competition while the second beats harm with efficiency or saves a failing firm gently |
| One deal against creeping slices | The first notifies once while the second aggregates every slice inside one year |
Exam Traps
- Per se agreements need no market definition while effects agreements always start with it, so skipping Section 26 fails even a proven cartel of the second kind.
- Oral, tacit, and informal concerted action counts as agreement, so no signed document is ever required.
- Bid rotation and cover bidding sit per se prohibited while output limits and market sharing wait for effects weighing.
- Sister firms under common control never conspire with each other, so intra-group coordination is not a Section 14 case.
- Crime needs Section 14(a) or 14(b) only, so abuse and merger cases never send officers to prison.
- Dominance alone never violates, so fifty percent share opens the case that conduct must still close.
- Below-cost selling abuses only with destructive object, while good-faith matching of a rival price is saved in the same paragraph.
- Superior product, business acumen, and legal rights never count as barriers, unfair prices, or output limits by themselves.
- Socialized pricing for the less fortunate stays permissible even by a dominant firm.
- Cost-based, rival-response, and market-driven price gaps survive while naked discrimination among similar traders falls.
- Unilateral termination rights save franchise and distributorship pacts while forced tying of unrelated goods condemns them.
- Intellectual property and trade-secret protections never violate by themselves.
- Unfairly low buying prices aimed at marginalized producers abuse on their own terms.
- Efficiency shared with consumers may save conduct that otherwise looks abusive.
- Closing during the thirty-day wait voids the deal even where the merger proves harmless, since gun-jumping punishes the act of closing.
- Deemed approval on ninety days of silence lets parties proceed, but fraud or false information reopens even a favorable ruling.
- Successive slices within one year count as one, so structuring below threshold deal by deal never works.
- The burden of the efficiency and failing-firm exemptions lies on the parties and never shifts to the Commission.
- A failing-firm rescue must be the least anti-competitive among known options and not merely better than liquidation.
- No franchise is exclusive and no incumbent holds a vested right against qualified entry, so blocking a rival never counts as legitimate competition.

Source and Verification Note
This reviewer reads the Part IV-B syllabus slice with the Chapter 15 headings for pages 1033 to 1064 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. Sections 4, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 26, and 27 of R.A. No. 10667 were checked against the full LawPhil Republic Act page, with the Official Gazette Act page confirming the July 21, 2015 approval. One LawPhil page artifact was normalized without changing substance, namely the misread verb in Section 14(b)(1) which is quoted here in its correct statutory form. Case doctrine comes from the Batch 3 digests for Tatad v. Secretary of DOE, Gios-Samar v. DOTC, and Eastern Telecommunications v. ICC, with dockets from the Batch 3 Case List. Syllabus numbers 73 and 74 duplicate numbers 68 and 67, and the Topic Mapping places both decisions in Chapter 14 free-competition doctrine at book page 967, so they carry no separate card here and Eastern Telecommunications appears once on its competition holding. The compiled 2016 to 2025 commercial-law questionnaire carries exactly one competition question, the 2024 electric-bicycle dominance problem, which is quoted verbatim in Part IV-A and not repeated here. Every drill in this Part IV-B file is therefore drafted from the doctrine with no year assigned. Current notification thresholds come from the PCC website and March 2026 advisories, namely SOP P9,100,000,000 with SOT P3,800,000,000 effective March 1, 2026, replacing P8,500,000,000 with P3,500,000,000 effective March 2025, and the creeping-transaction rule comes from the PCC merger FAQs restating IRR Rule 4 Section 3(e). 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.
