Section 306. Abetment of suicide
"If any person commits suicide, whoever abets the commission of such suicide, shall be punished with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine."
Section 307. Attempt to murder
"Whoever does any act with such intention or knowledge, and under such circumstances that, if he by that act caused death, he would be guilty or murder, shall be punished with imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine, and is hurt is caused to any person by such act, the offender shall be liable either to 1[imprisonment for life], or to such punishment as is hereinbefore mentioned."
So the debate should stop here whether Tappu is accused of both these crimes. She is without any doubt. If anyone thinks she is not either (s)he is blissfully aware of the law or is trying to defend the indefensible.
