XYZ is a Partnership Firm Auditor of a Listed Company for a period more than 15 years, but due to provisions of Rotation of Auditors XYZ will not be eligible to to reappointed for 5 Years. Mr. Z a non signing of XYZ Firm resigned and Joined a new CA Firm ABC and ABC appointed as Auditor of That listed Company. My question is that whether ABC can be appointed as Auditor of that Listed Company whose earlier auditor was XYZ ? Whether Mr. Z who resigned my XYZ can sign Audit report of that listed company on behalf of New CA Firm ABC?
