(1) The medical officer or mental health professional in charge of a mental health establishment shall admit every such person to the establishment, upon application by the nominated representative of the person, under this section, if—
         (a) the person has been independently examined on the day of admission or in the preceding seven days, by one psychiatrist and the other being a mental health professional or a medical practitioner, and both independently conclude based on the examination and, if appropriate, on information provided by others, that the person has a mental illness of such severity that the person,--
             (i) has recently threatened or attempted or is threatening or attempting to cause bodily harm to himself; or
             (ii) has recently behaved or is behaving violently towards another person or has caused or is causing another person to fear bodily harm from him; or
             (iii) has recently shown or is showing an inability to care for himself to a degree that places the individual at risk of harm to himself;
         (b) the psychiatrist or the mental health professionals or the medical practitioner, as the case may be, certify, after taking into account an advance directive, if any, that admission to the mental health establishment is the least restrictive care option possible in the circumstances; and
         (c) the person is ineligible to receive care and treatment as an independent patient because the person is unable to make mental healthcare and treatment decisions independently and needs very high support from his nominated representative in making decisions.
     (2) The admission of a person with mental illness to a mental health establishment under this section shall be limited to a period of thirty days.
     (3) At the end of the period mentioned under sub-section (2), or earlier, if the person no longer meets the criteria for admission as stated in sub-section (1), the patient shall no longer remain in the establishment under this section.
     (4) On the expiry of the period of thirty days referred to in sub-section (2), the person may continue to remain admitted in the mental health establishment in accordance with the provisions of section 90.
     (5) If the conditions under section 90 are not met, the person may continue to remain in the mental health establishment as an independent patient under section 86 and the medical officer or mental health professional in charge of the mental health establishment shall inform the person of his admission status under this Act, including his right to leave the mental health establishment.
     (6) Every person with mental illness admitted under this section shall be provided treatment after taking into account,—
         (a) an advance directive if any; or
         (b) informed consent of the patient with the support of his nominated representative subject to the provisions of sub-section (7).
     (7) If a person with the mental illness admitted under this section requires nearly hundred per cent. support from his nominated representative in making a decision in respect of his treatment, the nominated representative may temporarily consent to the treatment plan of such person on his behalf.
     (8) In case where consent has been given under sub-section (7), the medical officer or mental health professional in charge of the mental health establishment shall record such consent in the medical records and review the capacity of the patient to give consent every seven days.
     (9) The medical officer or mental health professional in charge of the mental health establishment shall report the concerned Board,—
         (a) within three days the admissions of a woman or a minor;
         (b) within seven days the admission of any person not being a woman or minor.
     (10) A person admitted under this section or his nominated representative or a representative of a registered non-governmental organisation with the consent of the person, may apply to the concerned Board for review of the decision of the medical officer or mental health professional in charge of the mental health establishment to admit the person to the mental health establishment under this section.
     (11) The concerned Board shall review the decision of the medical officer or mental health professional in charge of the mental health establishment and give its findings thereon within seven days of receipt of request for such review which shall be binding on all the concerned parties.
     (12) Notwithstanding anything contained in this Act, it shall be the duty of the medical officer or mental health professional in charge of the mental health establishment to keep the condition of the person with mental illness admitted under this section on going review.
     (13) If the medical officer or mental health professional in charge of the mental health establishment is of the opinion that the conditions specified under sub-section (1) are no longer applicable, he shall terminate the admission under this section, and inform the person and his nominated representative accordingly.
     (14) Non applicability of conditions referred to in sub-section (13) shall not preclude the person with mental illness remaining as an independent patient.
     (15) In a case, a person with the mental illness admitted under this section has been discharged, such person shall not be readmitted under this section within a period of seven days from the date of his discharge.
     (16) In case a person referred to in sub-section (15) requires readmission within a period of seven days referred to in that sub-section, such person shall be considered for readmission in accordance with the provisions of section 90.
     (17) If the medical officer or mental health professional in charge of the mental health establishment is of the opinion that the person with mental illness admitted under this section in the mental health establishment requires or is likely to require further treatment beyond the period of thirty days, then such medical officer or mental health professional shall be duty bound to refer the matter to be examined by two psychiatrists for his admission beyond thirty days.
