Under Section 7, a member of the Institute in practice must use the designation of a chartered accountant. Which of the following is expressly PERMITTED despite this requirement?

Section 7 requires every member in practice to use the designation “Chartered Accountant” and bars use of any other description in addition to or in substitution for it. However, the proviso permits a member to add other genuine descriptions or letters indicating membership of a recognised institute of accountancy or any other qualification he holds, and permits a firm whose partners are all practising members to be known by its firm name as Chartered Accountants. Self-coined or arbitrarily “prestigious” titles are not allowed, making it correct.
