Best Books for Delhi APP Exam 2026

The Union Public Service Commission (UPSC) has published the Delhi APP syllabus as a list of 15 Acts. Your Delhi APP books should therefore follow those Acts one by one, not broad subjects like “criminal law” or “commercial law”. 

With the test only weeks away, there’s no time to read a full textbook for every Act. Use the bare Act as your main text and keep commentaries for clearing doubts.The Delhi APP syllabus lists the topics covered under each Act.

Old IPC, CrPC and Evidence Act books won’t be enough on their own, because the Delhi APP exam on 9 January 2027 tests the 2023 criminal laws and their new section numbers.

The exam format tells you a lot about which books to buy:

Exam Feature (Delhi APP 2026)	What It Means for Your Books
Test on 9 January 2027, 2:00 PM to 4:00 PM, offline	About nine weeks of reading time from early November, so a short book list works better than a long one
Objective MCQs, English only	English-medium bare Acts and commentaries; Hindi editions won’t match the question wording
One-third negative marking	You need the exact statutory wording, and only the bare Act gives you that
15 Acts, led by the Constitution, BNS, BNSS and BSA	One commentary each for these four; bare Acts for the rest
IPC, CrPC and Indian Evidence Act not listed	Old-code books are for reference only
Final merit: 75% written test, 25% interview	The written paper decides most of the result, so choose books that improve MCQ accuracy

Subject-Wise Delhi APP Books 2026

The Delhi APP book list below pairs each area of the syllabus with one standard book, where a book actually helps.

The last column shows how many questions each area carried in UPSC’s January 2026 combined law paper, which had 120 questions for 300 marks.

Act / Area	Recommended Delhi APP Books	Jan 2026 Questions
Constitution of India	D.D. Basu, Shorter Constitution of India (LexisNexis) or J.N. Pandey, Constitutional Law of India (Central Law Agency)	24
Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS)	Ratanlal & Dhirajlal, The Bharatiya Nagarik Suraksha Sanhita, 2023 (LexisNexis)	17
Companies Act, 2013	Avtar Singh, Company Law (Eastern Book Company)	15
Bharatiya Nyaya Sanhita, 2023 (BNS)	Ratanlal & Dhirajlal, The Bharatiya Nyaya Sanhita, 2023 (LexisNexis)	14
Bharatiya Sakshya Adhiniyam, 2023 (BSA)	An evidence textbook in its BSA-revised edition (Batuk Lal or Avtar Singh)	13
PC Act, PMLA, DSPE Act, CVC Act	Bare Acts plus your own case-law sheet	18 (together)
IT Act and Competition Act	Bare Acts; Abir Roy and Jayant Kumar, Competition Law in India (EBC) if time allows	15 (together)
Environment (Protection) Act, 1986	Bare Act only	Small share
Indian Contract Act, 1872	Avtar Singh, Law of Contract and Specific Relief (EBC) or R.K. Bangia, Indian Contract Act	Not asked in Jan 2026
Trade Marks Act and GI Act, 1999	V.K. Ahuja, Law Relating to Intellectual Property Rights (trade marks and GI chapters)	Not asked in Jan 2026

Best Books for Constitutional Law

Read the bare Constitution first, then use D.D. Basu’s Shorter Constitution of India to check what an Article means. The Constitution was the largest block in January 2026, and the questions came straight from the text. 

One question asked which reservation has a percentage cap written into Article 16. The answer is EWS, up to 10% under Article 16(6), and you’ll find it in the bare text, not in a commentary.

Basu goes Article by Article, which suits an MCQ paper. J.N. Pandey is easier to read if you prefer a textbook. 

If time is short, M. Laxmikanth’s Indian Polity is handy for revising constitutional bodies and emergency provisions, though it lacks legal depth. Pick one of the three, not all of them.

Best Books for BNS, BNSS and BSA

For the new criminal laws, start with bare Acts that have section notes and an old-to-new comparison table, then use Ratanlal & Dhirajlal for each code.

 Taxmann’s Criminal Laws set and Professional Book Publishers’ New Criminal Laws manual both include these comparison tables. They help because most candidates first learned criminal law under the IPC, CrPC and Evidence Act.

For BNS, list the offences that didn’t exist under the IPC, such as organised crime, petty organised crime and terrorist act. For BNSS, keep a three-column change sheet: the CrPC section, the matching BNSS section, and what changed.

Best Books for Company Law

Avtar Singh’s Company Law (EBC) is the standard book here, but the questions reward a numbers table more than chapter reading. The Companies Act carried 15 questions in January 2026, one more than BNS. That catches most court-room advocates off guard.

UPSC asks about thresholds, for example:

• one-tenth of paid-up capital to requisition an extraordinary general meeting
• three-fourths in value to approve a scheme of arrangement
• the 2:1 debt-equity limit after a buy-back
• seven years before unclaimed amounts move to the IEPF

Read the chapters on share capital, meetings, management and compromises. Put every figure into one table, and revise that table rather than the whole book.

Best Books for Anti-Corruption and Money Laundering Laws

The PC Act, PMLA, DSPE Act and CVC Act need bare Acts and a case-law sheet, not textbooks. Together they carried 18 questions in January 2026, and many were based on Supreme Court rulings.

Start the case-law sheet with two judgments:

• Neeraj Dutta v. State (Govt. of NCT of Delhi) (2022): the Constitution Bench ruling on proving that a bribe was demanded and accepted through circumstantial evidence
• Vijay Madanlal Choudhary v. Union of India (2022): the leading ruling on the PMLA

Then add corruption and PMLA rulings from 2024 onwards. Read DSPE Sections 5 and 6, which cover the CBI’s jurisdiction and State consent, together with the CVC’s powers of superintendence.

Best Books for Other Laws in Delhi APP Syllabus

The IT, Competition, Environment, Contract, Trade Marks and GI Acts can be prepared almost entirely from bare Acts. These questions test whether you know which section does what:

• IT Act: Section 69 covers interception, 69A blocking and 69B traffic data.
• Competition Act: learn which Section 19 factors apply to agreements, to dominance, and to the relevant geographic and product markets.

Best Bare Acts for Delhi APP Exam Preparation

The most reliable bare Acts for the Delhi APP exam are the official texts on India Code, the Government of India’s free repository of central laws. If you prefer print, Universal LexisNexis, EBC and Taxmann all publish student editions. 

Whichever edition you buy, check the “as amended up to” date on the first page. A Companies Act or PMLA edition printed before 2024 may miss recent amendments.

Bare Act	Focus While Reading
Constitution of India	Parts III, IV, V and VI, Union Territory provisions, and every number in the text
BNS, BNSS and BSA, 2023	New and renumbered sections, time limits, electronic evidence
Companies Act, 2013	Thresholds, percentages and time periods
PC Act, PMLA, DSPE Act, CVC Act	Offences, sanction, attachment, and the role of the investigating agency
IT Act and Competition Act	Section-wise powers and definitions
Environment, Contract, Trade Marks and GI Acts	Definitions, main tests and offence sections

Best Delhi APP Books for MCQ Practice and Revision

Singhal’s CBI and Delhi Assistant Public Prosecutor (APP) Preliminary Examination (Singhal Law Publications, 4th edition, 2025) is the main exam-specific book for this paper. It covers special statutes such as the IT Act, PC Act, CVC Act, DSPE Act and PMLA. Use it for practice and quick revision, not as your first read. Check its answers against the bare Act, because guide books can lag behind amendments.

The same books also serve the CBI APP 2026 exam, since both posts sit for one UPSC paper.

In the last two weeks, stop opening new books. Revise from three things you made yourself: your change sheets, your numbers tables and your error log.

How to Choose the Best Books for Delhi APP 2026?

Choose books for the gaps in your own practice, not for the whole syllabus. Every candidate has at least three years at the Bar as per Delhi APP exam eligibility criteria, so nobody is starting from zero.

Your Practice Background	Where You’ll Lose Marks	Books to Prioritise
Criminal trial practice	Old CrPC and IPC habits; Companies and Competition Acts	Comparison tables for BNSS and BSA, Avtar Singh’s Company Law
Civil or commercial practice	BNSS procedure, BSA electronic evidence, PC Act case law	Ratanlal & Dhirajlal on BNSS and BNS, a BSA-revised evidence book
Corporate, tax or IP practice	Criminal procedure and the Constitution	Bare Constitution with D.D. Basu, a BNSS commentary
Mixed district-court practice	Special statutes and new section numbers	Bare Acts of the special statutes, change sheets

How to Prepare for Delhi APP Exam Using Recommended Books?

Read the bare Act before the commentary, every time. UPSC often builds a wrong option from the statute’s own words with one word changed: “may” for “shall”, “two-thirds” for “three-fourths”, “special resolution” for “special notice”. Only close reading of the bare text trains you to spot that.

Follow this order for each Act:

1. Read the bare Act section by section. Mark the definitions, time limits, numbers and penalties.
2. Open the commentary only for sections you didn’t follow, or to read the leading judgment on a section.
3. Write short notes: change sheets for BNS, BNSS and BSA, and numbers tables for the Constitution and the Companies Act.
4. Solve 30 to 50 MCQs on that Act.
5. Log each wrong answer in one line: the section, the trap and the correct rule.
6. Re-read the sections behind your wrong answers before you move on.

For a week-by-week schedule, use the 10-week plan in our Delhi APP preparation tips and adjust it to the time you have. The interview, worth 25% of the final merit, needs no new books. Prepare for it after the written test, using your own case files and recent Supreme Court and Delhi High Court criminal rulings.

Delhi APP Study Material and Previous Year Question Papers

The most useful Delhi APP study material is free:

• the bare Acts on India Code
• UPSC’s January 2026 Combined Recruitment Test paper for legal posts, available on upsc.gov.in

That paper used the same 15-Act syllabus. It is the closest match to what you’ll see on 9 January 2027.

Solve it in two hours with the one-third penalty. Then tag each question to its Act and section. You’ll quickly see which areas to give more time and which books to rely on. The Delhi APP exam pattern explains how negative marking and the 75:25 merit work.

Be careful with PDFs shared on messaging groups, because many still quote the IPC and CrPC. If you want guided preparation with mock tests,

Common Mistakes to Avoid While Selecting Delhi APP Books

• Buying pre-2024 criminal law books. They’re fine for concepts, but they give wrong section numbers and, in places, the wrong rule.
• Starting with a 1,500-page commentary. You won’t finish it in nine weeks. Keep it as a reference behind the bare Act.
• Skipping the non-criminal Acts. The Companies, IT and Competition Acts made up a quarter of the January 2026 paper.
• Collecting PDFs instead of reading. One annotated bare Act is worth more than ten unread files.
• Practising MCQs without the penalty. Untimed practice shows what you know, not what you’ll score.
• Buying Hindi-medium guides. The paper is in English only.
• Buying too many books. Five books read twice will serve you better than twelve read once. Other law exams need different lists; see our Delhi Judiciary books for that one.
