Guys.. Have a query.. Concerning a Church association.. Internal auditors were appointed at the last agm at the General meeting. After getting the association registered, external auditors were *given* to do the auditing of the association. Can this be done, in the sense, can the external auditors be given to do the auditing without approval of the general body at the agm? As far as ik, the external auditors should be appointed at one agm for the next year. So what happens in this case?? Do the internal auditors do the auditing for the current year or does the external auditors have the responsibility to do the same?
