What Section 329 CrPC Says

(1) If at the trial of any person before a Magistrate or Court of Session, it appears to the Magistrate or Court that such person is of unsound mind and consequently incapable of making his defence, the Magistrate or Court shall, in the first instance, try the fact of such unsoundness and incapacity, and if the Magistrate or Court, after considering such medical and other evidence as may be produced before him or it, is satisfied of the fact, he or it shall record a finding to that effect and shall postpone further proceedings in the case.

(1A) If during trial, the Magistrate or Court of Sessions finds the accused to be of unsound mind, he or it shall refer such person to a psychiatrist or clinical psychologist for care and treatment, and the psychiatrist or clinical psychologist, as the case may be shall report to the Magistrate or Court whether the accused is suffering from unsoundness of mind:

Provided that if the accused is aggrieved by the information given by the psychiatric or clinical psychologist, as the case may be, to the Magistrate, he may prefer an appeal before the Medical Board which shall consist ofโ€”

(a) head of psychiatry unit in the nearest government hospital; and

(b) a faculty member in psychiatry in the nearest medical college.

(2) If such Magistrate or Court is informed that the person referred to in sub-section (1A) is a person of unsound mind, the Magistrate or Court shall further determine whether unsoundness of mind renders the accused incapable of entering defence and if the accused is found so incapable, the Magistrate or Court shall record a finding to that effect and shall examine the record of evidence produced by the prosecution and after hearing the advocate of the accused but without questioning the accused, if the Magistrate or Court finds that no prima facie case is made out against the accused, he or it shall, instead of postponing the trial, discharge the accused and deal with him in the manner provided under section 330:

Provided that if the Magistrate or Court finds that a prima facie case is made out against the accused in respect of whom a finding of unsoundness of mind is arrived at, he shall postpone the trial for such period, as in the opinion of the psychiatrist or clinical psychologist, is required for the treatment of the accused.

(3) If the Magistrate or Court finds that a prima facie case is made out against the accused and he is incapable of entering defence by reason of mental retardation, he or it shall not hold the trial and order the accused to be dealt with in accordance with section 330.

Example of Section 329 CrPC

Ramesh is on trial before a Court of Session. During trial, the Court finds Ramesh to be of unsound mind and refers him under Section 329(1A) of the Code of Criminal Procedure, 1973 to a clinical psychologist for care and treatment. After the clinical psychologist reports that Ramesh is suffering from unsoundness of mind, the Court determines under Section 329(2) CrPC that this unsoundness of mind renders Ramesh incapable of entering defence and records a finding to that effect. The Court examines the prosecution evidence and hears the advocate of Ramesh without questioning Ramesh.
