1. Under Section 309 IPC attempted suicide is an offence. The Supreme Court has recommended repeal of this section. Similar demands have come from many other quarters.
2. While Section 309 IPC has not been repealed it stands practically whittled down in view of Mental Healthcare Act. Section 115 of Mental Healthcare Act runs as under:-
Section 115. PRESUMPTION OF SEVERE STRESS IN CASE OF ATTEMPT TO COMMIT SUICIDE.
(1) Notwithstanding anything contained in section 309 of the Indian Penal Code any person who attempts to commit suicide shall be presumed, unless proved otherwise, to have severe stress and shall not be tried and punished under the said Code.
(2) The appropriate Government shall have a duty to provide care, treatment and rehabilitation to a person, having severe stress and who attempted to commit suicide, to reduce the risk of recurrence of attempt to commit suicide.
3. Hence, in view of the provision of Mental Healthcare Act, Section 309 IPC is technically redundant. You may file a petition for quashing of FIR in the High Court.
