2 when reporting on an audit of financial statements, the user auditor should not refer to the service auditor's report.
3 the user auditor may not refer to a service auditor's report when expressing an opinion on the client's assertion on the effectiveness of internal control.
4 a user auditor cannot treat a service auditor's report as evidence if the period it covers does not coincide with that of the financial statements the user auditor has been engaged to audit
