Falsus in Uno, Falsus in omnibus

Falsus in Uno, Falsus in omnibus-

[Advocate]

Meaning of the maxim-
Literal meaning- "False in one thing, false in everything."
Essence- If a witness lies about one fact, their entire testimony is unreliable.
Applicability in India-
Under the BSA, this maxim does not have any statutory recognition.
Reason- Section 2(e) of BSA defines evidence, and the court is empowered to assess its credibility.
Section 119 (Illustration g)- Allows the court to presume that evidence which could be and is not produced would, if produced, be unfavorable. But this is only a presumption, not a mandatory rule like the maxim.
Indian Courts have consistently rejected a strict application of this doctrine because-
Instead, the courts follow the principle of "shifting the grain from the chaff" – accepting truthful portions and rejecting false ones.
Leading Case-




Bharatiya Nyaya Sakshya Adhiniyam connection-
|
Section 2(e) BSA (Sec. 3 IEA) |
Defines evidence — both oral and documentary. The credibility of a witness is left to the court's judgement. |
|
Section 119 BSA (Sec. 114 IEA)
|
Permits the court to presume facts, but doesn't mandate wholesale rejection of testimony. |
|
Section 158 & 149 BSA (Sec-155 & 146 IEA) |
Provide for impeachment of witness credibility (contradictions, character, etc) but do not compel rejection of the whole testimony. |
Principle Evolved in India -
Falsus in uno, falsus in omnibus-not applicable.
Instead, Indian courts apply:
Doctrine of separation of truth from falsehood. Testimony of witnesses is to be sifted carefully. Conviction can be based on credible parts, even if some parts are false.
