The recent controversy over President Donald Trump using his emergency authority to fund a wall on the U.S. southern border has made many Americans wake up to the problem of executive overreach. This public awaking to the real world difficulty of maintaining the separation of powers which most Americans learn about in high school civics classes is generally a good thing, and this author hopes that some of the current attention gets directed to the subject of U.S. securities regulation. In particular, there are problems in the current U.S. law on insider trading which were caused by executive overreach, and which reformers propose to correct with new executive actions.
A recent op-ed authored by a current Securities and Exchange commissioner and a former United States attorney has called for reform of the U.S. insider trading laws to make them more coherent and clear. The authors imply that the ambiguity in the law is the result of Congress failing to pass clear legislation. However, SEC and DOJ officials blaming Congress for the incoherence of U.S. insider trading laws is like a drunk driver blaming a light pole for jumping into the middle of the road. The ambiguity in the law is better explained as beginning with the actions of 1960s SEC commissioners who were unwilling to wait for Congress to pass a law prohibiting insider trading.
Federal prosecutions for insider trading are brought under the antifraud provisions of U.S. securities statutes, despite decades of state court decisions prior to 1961 which rejected insider trading as a form of fraud. The history of state court decisions is important, because when federal statutes set out to punish common legal violations without redefining the violation, federal courts will generally look to state law to determine the scope of the prohibited or mandated activity. This means that when Congress passes a law prohibiting fraud in securities transactions without redefining fraud, the state law definitions of fraud should control. U.S. insider trading law punishes parties with special access to information for failing to disclose that information before trading. In the 1960s and earlier, imposing liability for fraudulent nondisclosure in a business transaction required showing that the defendant intentionally withheld information which she had a duty to disclose to her counter party, and that her intent was to make the counterparty act in a specific way. Because participants who trade on stock exchanges do so without being able to influence their counter parties to participate, state courts rejected the claim that insider trading was a form of fraud. If you cannot make someone take an action, then you cannot be held liable for using deception to make that person act.
In its 1961 Cady, Roberts decision, without authority from Congress, the SEC originated the U.S. ban on insider trading by explicitly rejecting the state law definitions of ‘fraud’ and ‘fiduciary duty.’ In Cady, Roberts the SEC rejected the need to show that a defendant actually influenced the actions of his alleged victim, let alone that the defendant intended to influence the alleged victim’s trading decision. In the same case, the SEC also redefined which parties had and which parties were owed fiduciary duties. The state law generally recognized corporate directors as having fiduciary obligations to the corporate entity itself, not to shareholders. However, in the then radical Cady, Roberts opinion, the SEC asserted that under the federal antifraud provisions directors and many other insiders owe fiduciary duties of disclosure to everyone participating on securities exchanges—shareholders and non-shareholders. These dramatic changes in the scope of basic legal principles was described by the SEC as necessary to prevent the “inherent unfairness” of allowing insiders to trade with parties who do not have access to the same information. Of course, federal executives in the United States are not authorized to change U.S. law based solely on a personal judgement about what is necessary.
The drastic interpretive choices which the SEC made in Cady, Roberts makes it obvious that the ambiguity in modern U.S. insider trading regulation is not a matter of happenstance or merely the result of Congress failing to pass clear legislation. Because we use words to define other words, the SEC’s redefinition of these basic legal concepts had follow on effects which led to confusion and contradictions in U.S. securities law. But to be fair to the current executive agency officials calling for reform, there is some validity to the concern that Congress has been lax when it comes to legislating clear insider trading rules. In the 1980s, Congress passed two bills increasing the penalties faced for violating the prohibition on insider trading and clarifying which civilians had standing to sue in federal court. Congress chose not to define what constitutes insider trading in either bill. Congress failing to clearly define insider trading when it finally did pass insider trading legislation shows that executive overreach can be aided and abetted by legislative negligence. The 1980s Congress understood that targets of the ban on insider trading were facing years in prison and the confiscation of millions of dollars, and still chose not to clarify when someone would face such harsh punishments.
Fixing the incoherence in the U.S. regulation of insider trading requires keeping in mind that the problem began with executive overreach. This is important because the current self-appointed task force for reform takes for granted that the SEC itself has the authority to create new rules explicitly banning insider trading, so that they are no longer twisting the antifraud statutes passed by Congress beyond recognition. If the SEC did not have the authority to create rules prohibiting insider trading in 1961, and Congress failed to define the violation in the 1980s, then it is doubtful that the SEC currently has the authority to create rules banning insider trading. If nothing else, this author hopes that the controversy over President Trump’s emergency declaration will help voters and law makers to recognize that the question of executive overreach stretches far beyond the funding of a southern border wall.

Fraud cannot be presumed; it must be proved…The stock of the Cliff Mining Company was bought and sold on the stock exchange. The identity of buyers and seller of the stock in question in fact was not known to the parties and perhaps could not readily have been ascertained. The defendants caused the shares to be bought through brokers on the stock exchange. They said nothing to anybody as to the reasons actuating them. The plaintiff was no novice. He was a member of the Boston stock exchange and had kept a record of sales of Cliff Mining Company stock. He acted upon his own judgment in selling his stock. He made no inquiries of the defendants or of other officers of the company. The result is that the plaintiff cannot prevail.”) Also see Bainbridge, Insider Trading Law and Policy, pages 13-17.
