Things said or done by conspirator in reference to common design
The conspiracy rule: once a plot is reasonably shown, one conspirator’s words, deeds and writings about the design bind them all — to prove the plot, and to prove who belongs to it.
How to read Section 8
A threshold, a tether, a clock — and then the widest net in the chapter.
In a conspiracy, any one member’s acts, words and writings about the design are evidence against every member.
Threshold: reasonable ground first. Tether: only things in reference to the common intention. Clock: only after the design was first entertained.
It binds even a member who was ignorant of the act, done by a stranger to him, before he joined or after he left — the illustration says all three.
The bare Act
The section in its own words — colour-keyed by what each phrase does.
Where there is reasonable ground to believe that two or more persons have conspired together to commit an offence or an actionable wrong, anything said, done or written by any one of such persons in reference to their common intention, after the time when such intention was first entertained by any one of them, is a relevant fact as against each of the persons believed to be so conspiring, as well for the purpose of proving the existence of the conspiracy as for the purpose of showing that any such person was a party to it.
Reasonable ground exists for believing that A has joined in a conspiracy to wage war against the State.
The facts that B procured arms in Europe for the purpose of the conspiracy, C collected money in Kolkata for a like object, D persuaded persons to join the conspiracy in Mumbai, E published writings advocating the object in view at Agra, and F transmitted from Delhi to G at Singapore the money which C had collected at Kolkata, and the contents of a letter written by H giving an account of the conspiracy, are each relevant, both to prove the existence of the conspiracy, and to prove A’s complicity in it, although he may have been ignorant of all of them, and although the persons by whom they were done were strangers to him, and although they may have taken place before he joined the conspiracy or after he left it.
In short: conspiracy is teamwork — so the law treats the team as one actor. Show reasonable ground for the plot, and every member’s design-related words, deeds and writings — from the design’s birth onward — count against all of them, both to prove the plot and to fix each member in it.
→ The width is deliberate: plots are hatched in the dark, so the law lets each lit corner illuminate the whole room.
Glossary
An agreement of two or more to commit an offence or actionable wrong — the crime itself is defined in the BNS; this section is about evidence of it.
The threshold foundation — prima facie material of the plot, not full proof.
The shared object the members pursue — the tether every admitted act must connect to.
A civil wrong that can found a suit — the section covers civil plots too.
“One speaks for all” — each conspirator is treated as the agent of the rest for design-related acts.
The picture
The Act’s own illustration, drawn: seven hands, five cities, one design — and A at the edge, bound by it all.
The section, part by part
Tap a part — the picture-story tells it first; the word-by-word text and example follow.

§ 6 admits a person’s own conduct; § 8 goes further — a co-conspirator’s acts bind him too.

The offence itself lives in the Bharatiya Nyaya Sanhita — this section only supplies the evidentiary rule.
