Whenever any Trustee, either original or substituted, and whether appointed by any High Court or otherwise, shall die, or be six months absent from British India, or desire to be discharged from, or refuse, or become unfit or incapable to act in the trusts or powers in him reposed, before the same shall have been fully discharged and performed, it shall be lawful for the person or persons nominated for that purpose by the deed, will, or other instrument creating the trust (if any), or if there be no such person, or no such person able and willing to act, then for the surviving or continuing Trustees or Trustee for the time being, or the acting executors or executor, or administrators or administrator of the last surviving and continuing Trustee, or for the retiring Trustees, if they shall all retire simultaneously, or for the last retiring Trustee, or where there are two or more classes of Trustees of the instrument creating the trust, then for the surviving or continuing Trustees or Trustee of the class in which any such vacancy or disqualification shall occur (and for this purpose any refusing or retiring Trustee shall, if willing to act in the execution of the power, be considered a continuing Trustee) by writing to appoint any other person or persons to be a Trustee or Trustees in the place of the Trustee or Trustees so dying, or being absent from British India, or desiring to be discharged, or refusing or becoming unfit or incapable to act as aforesaid. So often as any new Trustee or Trustees shall be so appointed as aforesaid, all the trust property (if any) which for the time being shall be vested in the surviving or continuing Trustees or Trustee, or in the heirs, executors or administrators of any Trustee, shall with all convenient speed be conveyed and transferred so that the same may be legally and effectually vested in such new Trustee or Trustees, either solely or jointly with the surviving or continuing Trustees or Trustee, as the case may require. Every new Trustee to be appointed as aforesaid, as well before as after such conveyance or transfer as aforesaid, and also every Trustee appointed by any High Court either before or after the passing of this Act, shall have the same powers, authorities, and discretions, and shall in all respects act as if he had been originally nominated a Trustee by the deed, will, or other instrument (if any) creating the trust. The Official Trustee may with his consent, and by the order of the High Court, be appointed under this Section in any case in which only one Trustee is to be appointed and such Trustee is to he the sole Trustee.
