@ Balaji- If client introduce the staff members as auditors then it automatically doesnt makes those who arent auditor as auditor as per prevailing law.
Every client doesnt know abt who should be called as auditor and who shouldnt...it is on we the ca students and members who knows in depth on the said issue and should politely ask dos client to call dem as audit staf member and not auditor unless we really are.
Clients calls article trainee as auditor only for their convinenince.
