Dr. Jim Stewart:

It would be difficult to impose fines on enablers as long as they are acting within the law. That is a major issue that requires changes in the law and regulation of those changes rather than an attempt to fine enablers. The job of the professional firms that are performing services for oligarchs and others is to perform those services for their clients. What the client does with those services or how it behaves in other jurisdictions cannot be a part of the legal remit or requirement of those professional firms. They have a moral duty as opposed to a legal duty to ensure they are behaving in an ethical way.
