William J. Brennan, Jr., United States v. E. I. Du Pont De Nemours and Company…
“ To accomplish the congressional aim, the Government may proceed at any time that an acquisition may be said with reasonable probability to contain a threat that it may lead to a restraint of commerce or tend to create a monopoly of a line of commerce. [24] Even when the purchase is solely for investment, the plain language of § 7 contemplates an action at any time the stock is used to bring about, or in attempting to bring about, the substantial lessening of competition. ”
