Unajua auditors kazi yao ni kutoa upinion tu kwenye financial statements na si ku uncover frauds and other irregularities. So to them what matters is opinion. But there can be some issues related to fraud and other irregularities that may have come into attention after some period of time, there is where the issue of special audit arises. Kwenye irregularities mf. auditor alikuwa related to directors, not elected by shareholders etc. Kwahiyo mainly frauds na irregularities may lead to the renewal of the process. Ah imekuwa siku nyingi, am stand to be corrected.
