Now a days there is a big hue and cry against big 4 audit firms that they are not allowed to practice in India as per WTO terms but they are doing audit under surrogated firm's name. Still there is a demand for the experience got from these firms in the market. So such experience based on the brand can be fabricated (like Satyam's case). Can the big 4 take legal action on this fabricated experience certificate in the name of foreign firms?
