How to study Commercial and Taxation Laws for the 20% sitting

The BATAS editorial team··6 min read

The afternoon of Sunday, 5 September 2027 is Commercial and Taxation Laws: 20% of the weighted general average, in one sitting, on the first day. It is the largest sitting after Remedial Law and it is the one candidates most often study unevenly — deeply in corporations, thinly in banking, not at all in the special commercial laws.

This article is the map, in the syllabus's own order.

The seven blocks

BlockWhat it containsCharacter
I. Business organizationsCorporations under the Revised Corporation Code (RA 11232)The biggest block, and the most examinable
II. Insurance lawGeneral principles through rescission, including insurable interest, concealment, representation, warranties, double insuranceText-heavy: the Insurance Code, section by section
III. Transportation lawCommon carriers; vigilance over goods; safety of passengersSmall, doctrine-dense, case-driven
IV. Banking lawGeneral banking principles (RA 8791); secrecy of deposits (RA 1405, and the foreign-currency law); the BSP charter; deposit insurance; anti-money launderingStatutory, with precise thresholds and exceptions
V. Intellectual propertyPatents; trademarks; copyrightThree separate regimes, each with its own statute
VI. Special commercial lawsSecurities regulation (RA 8799); financial rehabilitation and insolvency (RA 10142); electronic commerce and digital trade; competition (RA 10667); public services (CA 146 as amended)The block candidates skip, and it is five statutes wide
VII. Taxation lawGeneral principles; national taxation under the NIRC; local taxation under the Local Government Code; real property taxation; taxpayer remediesHalf the sitting's second half, and pure doctrine

Two observations that change how you plan.

Block VII is half of the "and". The sitting's second half is not a footnote to commercial law. It is a subject with its own principles, its own procedures and its own remedies — see how to study taxation.

Blocks V and VI are wide and thin. Five special statutes plus three IP regimes, each worth a handful of questions at most. They reward a survey plus a small number of precise points, not depth.

Where the hours go

For 180 hours on this sitting (a proportional share of 900), a defensible split:

BlockHoursWhy
Corporations45The largest and most frequently examined block; the Code is long and the problems are structural
Taxation (all of VII)45Half the sitting's range, and doctrinal
Insurance25A code read section by section; distinctions are highly markable
Transportation15Small, but the common-carrier doctrine generates reliable questions
Banking15Thresholds, secrecy exceptions, AML reporting
Intellectual property15Three regimes, one statute each
Special commercial laws20Survey plus the two or three points each is actually tested on

Adjust for what you know. What you cannot do is spend 90 hours in corporations because it is familiar and 10 in everything else.

Corporations: the block that earns the most

The Revised Corporation Code is a procedural code as much as a substantive one, and that shapes how to study it.

  • Learn the life-cycle. Promotion and incorporation; the corporate personality and its consequences; shares and shareholders; the board and officers; meetings and voting; dividends; amendments; mergers and consolidation; dissolution and liquidation. A life-cycle outline makes every provision locatable.
  • The three doctrines that generate questions: separate juridical personality and when the veil is pierced; the trust-fund doctrine; and the powers of the corporation (express, implied, incidental).
  • The procedural provisions are checklists, and checklists are markable: the requirements for a valid meeting, the vote required for a given act, the period for a given filing. Learn them as lists rather than as prose.
  • Watch the one-person corporation and the remote-meeting provisions, which the Code added and which examiners have been testing since.

Insurance: read the code as a sequence

Insurance is the block where reading the statute in order is the right method, because the Code is drafted as a sequence of events: the contract is formed, a risk is described, a loss occurs, a claim is made, a policy may be rescinded.

Three high-value areas:

  • Insurable interest — who must have it, when, and over what.
  • Concealment and representation — the tests, the materiality requirement, and the effect on the policy.
  • Double insurance and over-insurance — the distinctions, and what the insured may recover.

Learn each as: rule, elements, effect.

Transportation: one doctrine, done well

The common-carrier doctrine is the whole block in miniature: the classification, the extraordinary diligence standard, the presumptions that follow from a loss, and the exceptions. That is a single page of doctrine that answers a disproportionate share of the questions this block produces — plus the passenger-safety branch, which is its own application of the same standard.

Banking: thresholds and exceptions

The banking block is examined through precise rules: the secrecy of deposits and its exceptions (which is where questions live), the foreign-currency regime, the BSP's powers, deposit insurance coverage, and the anti-money-laundering reporting obligations.

Two habits: memorise the exceptions as a list, and note which body may order disclosure. "The exception applies" without naming the exception scores little.

Intellectual property: three regimes, three statutes

  • Patents — patentability, the application, the rights conferred, and the grounds for cancellation.
  • Trademarks — registrability, the classes, the rights, and the remedies against infringement and unfair competition.
  • Copyright — the works protected, the rights, the limitations, and the term.

Each regime's examinable core is a short list. Learn the lists, then one application each.

Special commercial laws: survey, then precision

Five statutes. The honest approach is a survey of each (what it regulates, who administers it, what the main prohibition or remedy is), plus precision on two or three points:

  • Securities regulation — what a security is, the registration requirement, and the exemptions; the anti-fraud provision.
  • Financial rehabilitation and insolvency — the difference between rehabilitation and liquidation, and the commencement and its effects.
  • Electronic commerce and digital trade — the validity of electronic documents and signatures, and the obligations of online participants.
  • Competition — the prohibited agreements, abuse of dominance, and merger review.
  • Public services — the definition, the citizenship requirement, and the franchise regime as amended.

A survey answer scores the basic question. Precision wins the follow-up.

How to practise this sitting

The questions are typically: classify the entity or transaction; state the requirement or the vote; identify the remedy and who may invoke it; distinguish two institutions.

Three drills:

  1. The comparison table. For every pair the syllabus implies — ordinary versus preferred shares, concealment versus representation, rehabilitation versus liquidation, a security versus a non-security — write a two-column table with the consequence in a third.
  2. The provision drill. Take one section, write a fact pattern that turns on it, answer in twelve minutes.
  3. The half-sitting. Ten questions in two hours, alternating commercial and tax, which is how the afternoon actually feels.
