| There are plenty of victimless crimes on the statute books. The dispute over who might be theoretically harmed by insider trading relates to the legal theories proposed by courts and the SEC to justify the prohibition. Who might be harmed is of particular concern, particularly in the criminal domain, because we're dealing with an agency-created rule, and the courts are more-or-less following common law methodologies for specifying and circumscribing the rule. The applicable common law domain is Torts, and in Tort law there needs to be a breach of a duty to someone. Only once you identify that person (or persons) can you understand the scope of the duty owed them and by whom. The two competing theories are (1) that insider trading violates a fiduciary duty to the company from which the information came or (2) that insider trading violates a duty to the public at large, the so-called Fraud on the Market theory. The Fraud on the Market theory is what the SEC still clings to, but courts won't buy it because it's just too broad and doesn't really comport with established common law principles. An important self-constraint to fashioning non-statutory law is limiting oneself to extending pre-existing legal principles. The legislature isn't constrained by arcane legal technicalities. Their only constraint is the Constitution, which doesn't necessarily require shoe-horning laws into theoretically consistent buckets. The Fraud on the Market theory is too distant from any pre-existing legal principle, too distant from the plaintext of the existing statutes[1], and so only the legislature should be allowed to explicitly promulgate such a rule. [1] This is why we're talking about common law principles and not more recent administrative law principles. These days courts probably would never have allowed an administrative agency to invent something like insider trading, particularly as a crime, and so wouldn't have needed to make recourse to foundational common law principles. The courts accepted the prohibition prior to the modern development of administrative law. |
