My father have executed a Genaral power of Attorney to a person to covert the agriculture land into non-argiculture land in 2003 , later in 2008 He revoked the GPA by sending him the notice and giving the publication in the local daily news paper. After this event we had negotation and my father again given the continuation letter on bond which is again notriasied, My question here is according to GPA law once the GPA revocked can't be continued I mean we should do new GPA, whether is this my valid assumption can anybody clear this to me?
