Piercing the corporate veil prevents misuse of corporate personality to evade law and attribute acts to controlling persons. The doctrine of piercing the corporate veil allows courts to disregard a company's separate legal personality where it is used as a sham to defeat legal obligations, perpetrate fraud, or evade statutes; Indian decisions apply a fact-sensitive test-lifting the veil when statute contemplates it, when fraud or improper conduct is to be prevented, when public interest or revenue protection is involved, or when associated entities operate as one concern despite separate registration.
