Liability will attach personally or directly to the SHs or officers or where there are two corporations, they will be merged as one, the one being merely regardedas the instrumentality, agency, conduit or adjunct of the other. A corporation will be looked upon as a legal entity as a rule, and until sufficientrea son to the contrary appears; but when the notion of legal entity is used to defeat publicconvenience, justify wrong, protect fraud, or defend crime, the law will regard the corporationas an association of persons.
