How to study Political and Public International Law for the 15% sitting

The BATAS editorial team··5 min read

Political and Public International Law is the first paper of the 2027 Examinations — the morning of Sunday, 5 September 2027, worth 15% of the weighted general average. It is also the subject most likely to be studied out of order, because candidates tend to begin with the Bill of Rights, which is the most interesting part and the third act.

This article is a map of the subject as the syllabus actually arranges it, with the study consequences.

Read the syllabus's order as a curriculum

The published coverage runs in nine movements. That is not an accident of drafting; it is the order in which the concepts depend on each other.

BlockWhat it coversWhy it comes here
I. Basic conceptsThe Constitution; the State; constitutional design; the fundamental powers; declaration of principlesEverything after this assumes it
II. National territory and maritime zonesScope of territory; archipelagic doctrine and baselines; sea lanes; maritime zones (UNCLOS, RA 9522, RA 12064, RA 12065)The territory defines the jurisdiction everything else operates in
III. CitizenshipWho are citizens; acquisition; natural-born and naturalized; loss and reacquisition; dual citizenshipOnly citizens hold the offices the next four blocks describe
IV. Legislative departmentChambers; qualifications; privileges; plenary power; non-legislative powers; initiative and referendumFirst of the three departments
V. Executive departmentQualifications; privileges; powers; successionSecond department
VI. Judicial departmentJudicial power; judicial review; independence; appointments; the Supreme CourtThird department
VII. Constitutional commissionsCommon provisions; the CSC, COMELEC, COAIndependent bodies the three departments interact with
VIII. Bill of RightsDue process through the rights of the accusedThe rights that bind all of the above
IX. Public international lawSources; statehood; treaties; immunities; jurisdictionThe international frame, which is why it is the last movement

Two practical consequences:

  • Do not start at the Bill of Rights. You will meet due process before you have settled what the State is, what sovereignty means, or what the police power does — and due process is largely the story of those three.
  • The first block is short and carries a lot. Nature of the Constitution; self-executing versus non-self-executing provisions; amendment versus revision; the elements of the State; state immunity; separation of powers; checks and balances; delegation; the three fundamental powers. Studying it properly in week one saves months of confusion later.

Where the hours should go

The sitting is 15%. Inside that, the blocks are not equal, and neither are the marks.

A defensible allocation for the year:

BlockShare of the subject's hours
Bill of Rights~30%
The three departments (legislative, executive, judicial)~25%
Basic concepts~15%
Public international law~12%
Constitutional commissions~8%
Territory and maritime zones~5%
Citizenship~5%

The Bill of Rights dominates because it generates the most examinable doctrine per page and the most case law. The departments dominate the structure because questions about powers, qualifications and immunity are frequent and precise. Public international law gets a real share precisely because most candidates give it none.

The case-heavy blocks, and how to handle them

Political law is the subject where a candidate can drown in jurisprudence. Three rules keep it manageable:

  • Learn the test before the cases. For every doctrine, write the test in a sentence. Then note one case for each direction the test can go. A list of ten cases without the test is unusable in an answer.
  • Only the main opinion counts. The Bulletin says so explicitly: doctrines and dispositions in the main opinion are what is examinable — not concurrences, not dissents. That is a large saving in reading, and it should change what you note.
  • Prefer the provision to the case. For qualifications, periods, majorities and immunities, the Constitution itself is the authority and it is shorter than the case law about it. Learn the text; use the cases for the hard edges.

Public international law: the component candidates skip

The syllabus dedicates a real block to it, and it is examined as part of a 15% sitting. It is usually skipped because it feels optional, unfamiliar, and disconnected from the rest.

Three things make it tractable:

  • The sources and the hierarchy. Treaties, custom, general principles, and the relationship between international law and domestic law — including how a treaty becomes enforceable here. That is a small, self-contained body of doctrine.
  • The maritime material is the most concrete part, and the syllabus names its instruments (UNCLOS with its archipelagic provisions, and the statutes on baselines and maritime zones). Concrete means markable: you can state a zone and its legal consequence.
  • State immunity, jurisdiction and immunities are examined inside the same block as the State in basic concepts, so study them together rather than as foreign material.

Twelve hours across the year is enough to hold this block at answering level — which, for 12% of a 15% sitting, is good value.

How to practise it

Political law questions reward precision, not breadth. The shapes you will meet: "May Congress…", "Is the provision constitutional…", "Does the court have jurisdiction over…", "Is the official liable/immune…", "What is the doctrine and does it apply".

Practise in three drills:

  1. Provision-to-answer. Take a provision, write a question that turns on it, and answer it in twelve minutes. The Constitution is a list of examinable rules; convert it into questions.
  2. The two-column test. For each doctrine with a balancing test, write a fact on each side of the line. The answer is the line, not the doctrine's name.
  3. The ten-minute outline. Take a past question, produce the conclusion and the rule with its elements, and stop. This is how you cover volume without spending twelve minutes per question — see past bar questions.

What "constitutional structure" means as an exam topic

Because it is the spine of the paper, the departments get their own article: the constitutional structure sets out how the three departments and the commissions fit together, and the tests that questions about them keep using.

The 15% framing

This is the first paper of the week and a mid-weight subject. Two things follow:

  • Bank it early. Finishing the Basic Concepts block in the first two months means everything later is easier; leaving it to the end means studying the departments without their vocabulary.
  • Do not over-invest at the expense of the quarter. Political law rewards a disciplined outline and a lot of practice; it does not need the hours that Remedial Law needs. See playing the weights for the arithmetic across sittings.
