Owing to the auditors qualification and independence the 1844 Act was repecced and replace by 1856 Act.

The 1956 act introduced the idea that the auditor need not be a shareholder as well provided a set of model regulzation which a company was not found to adopt. The companies act 1877 made the appointment or the auditor compulsory for banking companies and this was finally extended to all companies through the  1990 act prior the 1992 the auditors reports was defended to cover profit and loss account while the 1984 Act extended it to profit and loss disclosure requirement.
