Whether the principal or donor can cancel the agency or power of attorney?

The principal or donor may cancel the agency or power of attorney with due notice. Further, proper notice should be given to the public. Such agency also gets cancelled, when the work for which agency was granted is completed or by the death of the principal /donor or agent or any one of them becomes of unsound mind or insolvent.                             

However, if the agent himself has any interest in the property which is a subject matter of agency, it cannot be cancelled, unless the agent agrees. Further, the principal cannot cancel the agency after the agent has partially exercised his authority. In case of power of attorney given to sell the property, if the power of attorney holder has entered into a sale agreement in accordance with the terms of power of attorney the donor cannot cancel the power of attorney until the sale is completed and the sale agreement is binding on the principal.
