Witness not excused from answering on ground that answer will criminate
Answer now, protected later. A witness cannot refuse to answer a relevant question merely because the answer might incriminate him or expose him to a penalty — but the compelled answer earns use immunity: it cannot be used to arrest or prosecute him, save for a prosecution for giving false evidence.
How to read Section 137
A witness must answer a relevant question even if the answer would incriminate him — and in return, that compelled answer cannot be used against him, except if he lies.
A witness is not excused from answering a question relevant to the matter in issue — even if the answer would criminate him or expose him to a penalty or forfeiture.
In return, a compelled answer earns use immunity.
The answer cannot subject him to arrest or prosecution, nor be proved against him — except a prosecution for giving false evidence by that answer.
The bare Act
The section in its own words — the compulsion, and a protective proviso.
A witness shall not be excused from answering any question as to any matter relevant to the matter in issue in any suit or in any civil or criminal proceeding, upon the ground that the answer to such question will criminate, or may tend directly or indirectly to criminate, such witness, or that it will expose, or tend directly or indirectly to expose, such witness to a penalty or forfeiture of any kind:
Proviso.—Provided that no such answer, which a witness shall be compelled to give, shall subject him to any arrest or prosecution, or be proved against him in any criminal proceeding, except a prosecution for giving false evidence by such answer.
In short: the search for truth comes first — a witness may not stay silent on a relevant question just because a truthful answer would incriminate him, tend to incriminate him directly or indirectly, or expose him to a penalty or forfeiture. But the law does not make him hang himself by his own compelled words. The proviso gives a matching use immunity: an answer he was compelled to give shall not subject him to any arrest or prosecution, and shall not be proved against him in any criminal proceeding. There is one carve-out — if he lies, the answer can be used to prosecute him for giving false evidence. So the bargain is simple: tell the truth, and your words cannot be turned against you; the only way to lose the shield is to abuse it by lying.
→ This carries forward IEA 1872 § 132 — compulsion to answer, matched by use immunity for the compelled answer.
