Law of Evidence
Plea of Alibi, Test Identification and Conspiracy in Evidence Law
Learn how absence from the scene, identification evidence and acts or statements of conspirators are proved under Sections 7 to 9 and the burden-of-proof rules.
The short answer
Alibi seeks to make presence impossible, identification connects a person to the event, and conspiracy may be inferred from coordinated conduct and admissible acts or statements made in reference to common design.
Plea of alibi
Alibi means elsewhere. It is a rule of relevancy, not a separate general defence.
Section 9 makes facts relevant when they are inconsistent with a fact in issue or make its existence highly probable or improbable. The prosecution must first prove the accused's presence and participation beyond reasonable doubt.
Because the accused relies on a special fact within personal knowledge, the burden of establishing alibi then falls on the accused. The evidence must exclude presence at the scene with the required certainty. A weak alibi does not repair a weak prosecution case.
Test Identification Parade
A TIP tests whether a witness who did not previously know the suspect can identify that person without suggestion.
Purpose
It provides investigative assurance and tests the witness's memory at an early stage. Identification in court is substantive evidence, while a fair prior parade ordinarily supplies corroboration.
Fairness factors
Delay, prior exposure to the suspect or photographs, suggestive line-ups, material differences among participants and weak opportunity to observe can reduce value.
No mechanical rule
Failure to hold a TIP is not always fatal, especially where the witness already knew the accused. Where the accused was a stranger and identification is central, omission or contamination may be serious.
Proving conspiracy through connected acts and statements
Conspiracies are usually formed in secrecy, so direct proof is uncommon.
Section 8 makes relevant things said, done or written by a person in reference to the common design after there is reasonable ground to believe that two or more persons conspired to commit an offence or actionable wrong.
The court first looks for prima facie material connecting the alleged participants to a common design. It then evaluates conduct, communications, preparation and coordinated acts as a whole. Mere association, knowledge or presence does not by itself prove agreement.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Binay Kumar Singh v. State of Bihar
(1997) 1 SCC 283
Facts: The accused relied on alibi to contend that presence at the scene was impossible.
Legal question: How do the prosecution burden and the accused's burden on alibi operate together?
Held: The prosecution retains the primary burden of proving presence and guilt. An accused relying on alibi must establish it so as to exclude the possibility of presence at the relevant place and time.
Reasoning: The prosecution must prove presence and guilt first. The accused must then establish the special plea with evidence sufficiently certain to exclude presence at the relevant time and place.
Why it matters: Use it to explain the correct sequence of burdens.
Read the judgmentRaja v. State by the Inspector of Police
(2020) 15 SCC 562
Facts: Identification was disputed through objections about delay and possible prior exposure of witnesses to the accused or photographs.
Legal question: Which defects reduce the evidentiary value of a Test Identification Parade?
Held: Identification evidence must be assessed on its circumstances. Prior exposure may destroy the value of a parade, while delay alone is not invariably fatal if fairness is otherwise preserved.
Reasoning: The Court treated prior exposure as capable of making a parade inconsequential, while refusing to make delay alone fatal in every case. The entire fairness of the process matters.
Why it matters: Use it to analyse a contested or delayed identification parade.
Read the judgmentKehar Singh v. State (Delhi Administration)
(1988) 3 SCC 609
Facts: The prosecution relied on a chain of meetings, conduct and surrounding circumstances to prove participation in a secret plan to assassinate the Prime Minister.
Legal question: Can the agreement at the heart of conspiracy be inferred from circumstantial evidence?
Held: Agreement may be inferred from proved circumstances and coordinated conduct because a conspiracy is ordinarily conceived and executed in secrecy.
Reasoning: Yes. Secrecy makes direct proof unusual, so coordinated conduct and circumstances may establish agreement. Mere relationship or association remains insufficient.
Why it matters: Use it to explain circumstantial proof of common design while rejecting mere association.
Using this topic in a legal answer
A clear answer sequence
- Identify whether the problem concerns presence, identity, common design or more than one issue.
- For alibi, state the prosecution's primary burden before discussing the accused's special burden.
- For TIP, assess opportunity to observe, promptness, prior exposure and fairness of the procedure.
- For conspiracy, identify prima facie independent material showing common design before relying on Section 8.
- Conclude separately on admissibility, credibility and final proof.
Points that are often confused
- Treating failure of alibi as proof of guilt.
- Calling a police-station identification a fair TIP without examining prior exposure.
- Using every statement by an alleged conspirator without first showing common design.

Rules to retain
- Alibi is relevant under Section 9 because it is inconsistent with presence.
- The prosecution's burden does not disappear when alibi is raised.
- A TIP tests memory and ordinarily corroborates later court identification.
- Prior exposure can seriously weaken a parade.
- Section 8 requires a prima facie common design, not mere association.
Questions to test understanding
- Does failure to prove alibi automatically establish guilt?
- Why is prior exposure relevant to a TIP?
- What foundation is needed before Section 8 applies?
Questions students ask
Who bears the burden of proving alibi?
The prosecution must first prove guilt and presence. The accused bears the burden of establishing the special plea of alibi sufficiently to exclude presence, but failure of the plea cannot substitute for prosecution proof.
Is a Test Identification Parade substantive evidence?
Identification in court is ordinarily treated as substantive evidence. A properly conducted earlier parade tests and corroborates the witness's ability to identify a previously unknown person.
Can conspiracy be proved without direct evidence of an agreement?
Yes. It may be inferred from a coherent chain of conduct, communications and circumstances. The inference must establish agreement, not merely acquaintance, presence or suspicion.
