13.1 Chapter 1 — Preliminary Definitions
Key Takeaways
CrPC Chapter 1 (especially s.4) is the procedural dictionary: cognizable vs non-cognizable and bailable vs non-bailable drive almost every later arrest, FIR, and bail MCQ
Cognizable offence (s.4): police may arrest without warrant under the Second Schedule or other law; non-cognizable: police may not arrest without warrant
Bailable offence: shown as bailable in the Second Schedule or made bailable by other law; non-bailable means any other offence—bail is still possible but not as of right under the bailable pathway
Complaint is an allegation to a Magistrate for action under the Code and does not include a police officer’s report; inquiry is magisterial/court fact-finding other than trial; investigation is evidence-collection by police or authorised non-Magistrate
Warrant-case vs summons-case turns on the maximum punishment threshold in the Code’s definitions (classic Pakistan 1898 teaching: warrant-case if death, life, or imprisonment exceeding six months)—procedure of trial chapters follows this split
Chapter 1 — Preliminary Definitions
Quick Answer: For LAW-GAT’s CrPC (10 marks) block, Chapter 1 is pure definition scoring. Master section 4 labels: cognizable / non-cognizable, bailable / non-bailable, complaint, inquiry, investigation, judicial proceeding, offence, officer in charge of a police station, summons-case, and warrant-case. These words decide who may arrest, whether FIR-style police action is free, how trials are classified, and how bail language works later in Chapter 39.
Why Chapter 1 Is the CrPC Gate
The Code of Criminal Procedure, 1898 (as applied in Pakistan) is a machinery statute. Offence substance lives mainly in the PPC and special laws; CrPC tells courts and police how to start, stop, compel, investigate, try, and review. Chapter 1 supplies the vocabulary. If you mix complaint with FIR/police report, or treat every serious offence as automatically non-bailable without checking the Second Schedule idea, you will miss easy stems.
Syllabus placement: CrPC chapters tested on LAW-GAT include 1, 5, 7, 8, 10, 11, 14, 16, 17, 31, 39. Chapter 1 is the foundation for arrest (Ch 5), security (Ch 8), FIR/investigation (Ch 14), complaints (Ch 16), and bail (Ch 39).
Reading rule: Definitions apply unless a special law or later section provides a different meaning for its own purposes. Always prefer the Code’s own definition over everyday English.
How to Attack Definition MCQs
| Step | Action |
|---|---|
| 1 | Spot the defined word (cognizable, complaint, warrant-case…) |
| 2 | Recall the s.4 core test—not a coaching slogan |
| 3 | Apply Second Schedule / other-law hooks where the definition uses them |
| 4 | Eliminate near-synonyms (inquiry ≠ investigation ≠ trial; complaint ≠ police report) |
Cognizable vs Non-Cognizable
Cognizable offence / cognizable case
A cognizable offence is an offence for which, and a cognizable case is a case in which, a police officer may, in accordance with the Second Schedule or under any other law for the time being in force, arrest without warrant.
Non-cognizable offence / non-cognizable case
A non-cognizable offence is an offence for which, and a non-cognizable case is a case in which, a police officer may not arrest without warrant.
Comparison table (high-yield)
| Feature | Cognizable | Non-cognizable |
|---|---|---|
| Arrest without warrant | Yes (when Schedule/other law so provides) | No (police need warrant/order pathway) |
| Typical seriousness (teaching rule of thumb) | Often more serious scheduled offences | Often less serious scheduled offences |
| Police initiative | Greater freedom to arrest and investigate once lawfully seised of the case | More restrained; Magistrate’s order themes for investigation |
| Everyday examples (illustrative only—always check Schedule/special law) | Murder, robbery, many serious body/property crimes as scheduled | Many petty assaults, defamation-type private wrongs as scheduled |
| Exam trap | “Serious-looking” fact pattern still needs Schedule/law authorisation | Not every private dispute is non-cognizable |
Policy idea: Cognizability is about police power to arrest without warrant, not a moral ranking invented by the candidate. The Second Schedule (and special statutes that declare an offence cognizable) is the statutory switch.
Link forward: Chapter 14 investigation/FIR practice is built on whether the information discloses a cognizable offence. Do not confuse cognizability with bailability—they are independent axes.
Bailable vs Non-Bailable
Bailable offence
A bailable offence means an offence shown as bailable in the Second Schedule, or which is made bailable by any other law for the time being in force.
Non-bailable offence
A non-bailable offence means any other offence.
Comparison table (high-yield)
| Feature | Bailable | Non-bailable |
|---|---|---|
| Statutory label | Shown bailable in Second Schedule or other law | Everything not so shown/made bailable |
| Bail as of right theme | Stronger claim to bail when the offence is bailable (subject to Code bail chapter conditions) | Bail is discretionary under the non-bailable pathway—not automatic refusal |
| Common trap | “Non-bailable = never get bail” | Wrong—Chapter 39 still allows bail on judicial satisfaction |
| Relation to cognizable | Independent classification | Independent classification |
Two-axis grid (memorise)
| Bailable | Non-bailable | |
|---|---|---|
| Cognizable | Police may arrest without warrant; bail pathway is the bailable track | Police may arrest without warrant; bail is the non-bailable (discretionary) track |
| Non-cognizable | No warrantless police arrest; bailable track if charged/produced | No warrantless police arrest; non-bailable track |
Exam power: A stem can be cognizable and bailable, cognizable and non-bailable, etc. Answer only what the question asks.
Complaint, Inquiry, Investigation, Judicial Proceeding
Complaint
Complaint means the allegation made orally or in writing to a Magistrate, with a view to his taking action under this Code, that some person, whether known or unknown, has committed an offence, but does not include the report of a police-officer.
| Is a complaint | Is not a complaint under this definition |
|---|---|
| Oral or written allegation to a Magistrate seeking Code action | Police report / police diary narrative alone |
| Can name known or unknown accused | Purely internal police memo not addressed as a Magistrate complaint |
| Purpose: Magistrate action under CrPC | Civil plaint in a civil court (different Code) |
Trap: Students equate “I complained at the thana” with complaint. Under s.4, complaint is a Magistrate-facing allegation. Police first information is handled through Chapter 14 machinery and is not a “complaint” in this defined sense.
Inquiry
Inquiry includes every inquiry other than a trial conducted under this Code by a Magistrate or Court.
| Inquiry | Trial |
|---|---|
| Magisterial/court process of fact-finding under the Code | Full adjudication of guilt with the trial procedure applicable |
| Explicitly not a trial | Ends in conviction/acquittal pathways |
Examples of inquiry flavour (teaching): proceedings to see whether action under security chapters should continue; certain pre-trial magisterial checks—always ask: is a Magistrate/Court conducting non-trial Code inquiry?
Investigation
Investigation includes all the proceedings under this Code for the collection of evidence conducted by a police officer or by any person (other than a Magistrate) who is authorised by a Magistrate in this behalf.
| Actor | Typical label |
|---|---|
| Police collecting evidence under the Code | Investigation |
| Person (not a Magistrate) authorised by a Magistrate to collect evidence | Investigation |
| Magistrate/Court conducting non-trial Code process | Inquiry (not investigation) |
| Full hearing on charge under trial chapters | Trial |
Golden triangle:
- Investigation → evidence collection (police / authorised non-Magistrate)
- Inquiry → Magistrate/Court, not trial
- Trial → adjudication of guilt under trial procedure
Judicial proceeding
Judicial proceeding includes any proceeding in the course of which evidence is or may be legally taken on oath.
Exam cue: If the proceeding is one where oath-evidence can be taken, it sits inside “judicial proceeding” language used across offences against public justice and procedural protections.
Offence; Officer in Charge of a Police Station; Related Labels
Offence
Offence means any act or omission made punishable by any law for the time being in force (including, where the definition so extends, special/local law contexts as drafted). Working exam sense: a punishable legal wrong—not every civil breach or moral wrong.
Link to PPC s.40: PPC and CrPC “offence” ideas reinforce each other; CrPC procedure applies to offences as the Code and special laws provide.
Officer in charge of a police station
Officer in charge of a police station includes, when the officer in charge is absent from the station-house or unable from illness or other cause to perform his duties, the police officer present at the station-house who is next in rank to such officer and is above the rank of constable (or, where no such officer is present, certain residual arrangements as the definition states).
| Point | Why it matters |
|---|---|
| Functional definition | Rank-and-file constable alone is not automatically “SHO/officer in charge” |
| Absence/illness | Next senior present officer (above constable) can fill the role |
| Later chapters | FIR registration, investigation direction, and production duties often attach to this office |
Police station (related)
A police station is a post or place declared generally or specially by the Provincial Government to be a police station, and includes any local area so specified. Jurisdiction of investigation often tracks the station’s local limits plus special extensions in later chapters.
Summons-Case vs Warrant-Case
These definitions classify how the case is tried (summons procedure vs warrant procedure), not whether a summons or warrant was used to compel appearance at the first moment.
Warrant-case
A warrant-case means a case relating to an offence punishable with death, imprisonment for life, or imprisonment for a term exceeding six months (classic CrPC 1898 teaching definition used in Pakistan materials—confirm the exact words in your bare-act edition).
Summons-case
A summons-case means a case relating to an offence, and not being a warrant-case.
Comparison table
| Feature | Warrant-case | Summons-case |
|---|---|---|
| Definition hook | Offence punishable with death, life, or imprisonment > six months (1898 threshold teaching) | Residual: everything that is not a warrant-case |
| Procedure flavour | Heavier trial machinery (charge, more formal steps) | Lighter summons-trial machinery |
| Trap | “Police used a warrant to arrest, so it is a warrant-case” | Classification follows maximum punishment, not the process paper used to arrest |
| Trap | “Summons-case means only summons can issue for attendance” | Wrong—labels are about trial class, not exclusive process type |
Note on India vs Pakistan teaching: Indian CrPC 1973 uses a two-year threshold for warrant-cases. LAW-GAT is a Pakistan exam on the 1898 Code tradition—do not import the two-year Indian figure unless your edition has been expressly amended that way. When in doubt, open your Pakistan bare act definition clause.
Other s.4 Labels Worth a Quick Pass
| Term (as defined/used) | Core exam sense |
|---|---|
| Charge | Includes any head of charge when the charge contains more heads than one |
| High Court | The High Court for the province/territory as constitutionally/statutorily constituted |
| Public Prosecutor | Person appointed under the Code to conduct prosecutions (appointment pathway in later sections) |
| Pleader / Advocate | Legal practitioner categories as defined for appearance and defence rights |
| Magistrate classes | First/second/third class (and Executive/Judicial distinctions as adapted in post-separation reforms)—jurisdiction tables later depend on class |
You need not memorise every minor label for LAW-GAT, but you must never confuse complaint / investigation / inquiry / trial.
Master Definition Table (Chapter 1 for LAW-GAT)
| Definition | One-line memory |
|---|---|
| Cognizable | Police may arrest without warrant (Schedule/other law) |
| Non-cognizable | Police may not arrest without warrant |
| Bailable | Schedule (or other law) marks it bailable |
| Non-bailable | Any other offence |
| Complaint | Allegation to Magistrate for Code action; not police report |
| Inquiry | Magistrate/Court process other than trial |
| Investigation | Evidence collection by police / authorised non-Magistrate |
| Judicial proceeding | Proceeding where evidence may be taken on oath |
| Offence | Act/omission punishable by law |
| Officer in charge | SHO or next present officer above constable when SHO absent/unable |
| Warrant-case | Death / life / imprisonment > 6 months (1898 teaching) |
| Summons-case | Not a warrant-case |
Exam Trap Table
| Stem pattern | Prefer |
|---|---|
| Can police arrest without warrant? | Cognizable analysis |
| Is bail “as of right” language or discretionary track? | Bailable vs non-bailable |
| Allegation filed before Magistrate (not police report) | Complaint |
| Police collecting evidence | Investigation |
| Magistrate checking facts, not full trial | Inquiry |
| “Warrant-case because arrest warrant issued” | False—use punishment threshold |
| Cognizable therefore non-bailable | False—independent axes |
| Non-bailable therefore never bail | False—bail chapter still operates |
Memory Card: Chapter 1
- Cognizable = arrest without warrant power (Schedule/law)
- Bailable = Schedule/other law label; non-bailable = residual
- Complaint → Magistrate; excludes police report
- Investigation (police evidence) ≠ inquiry (court/Magistrate non-trial) ≠ trial
- Warrant-case = death / life / > 6 months imprisonment (1898 teaching)
- Officer in charge = functional; next above constable if SHO out
- Two axes: cognizability × bailability
Key Takeaways
- Chapter 1 definitions are the operating system for the rest of CrPC
- Cognizable/non-cognizable is about warrantless arrest power
- Bailable/non-bailable is a separate Second Schedule (or other-law) label
- Complaint ≠ police report; investigation ≠ inquiry ≠ trial
- Warrant-case / summons-case follow the Code’s punishment threshold, not the paperwork used to catch the accused
Under the CrPC definition of a cognizable offence, a police officer may arrest without warrant when:
The offence is shown as cognizable in the Second Schedule or under any other law for the time being in force
The complainant personally requests arrest, even if the offence is scheduled as non-cognizable
Any civil dispute is reported at a police station regardless of the Second Schedule
The offence is bailable, because bailable and cognizable are statutory synonyms
Which statement correctly reflects the CrPC definition of “complaint”?
Any oral story told to a neighbour about a crime
Only a written petition filed in the High Court under constitutional jurisdiction
The daily diary entry made by a head constable for internal station records alone
An allegation made orally or in writing to a Magistrate, with a view to his taking action under the Code, that some person has committed an offence—excluding a police officer’s report
How do “investigation” and “inquiry” differ under CrPC Chapter 1 definitions?
Investigation is always conducted by a Magistrate; inquiry is always conducted only by police
They are statutory synonyms for every stage after FIR registration
Investigation is collection of evidence by a police officer (or authorised non-Magistrate); inquiry is a non-trial process conducted by a Magistrate or Court under the Code
Inquiry means the final judgment of guilt; investigation means only the sentencing hearing
