A criminal action was filed against Dr. Sriram for mail fraud and health-care fraud involving Medicare. In connection with that action, the government filed a civil action seeking a preliminary injunction maintaining a freeze on Dr. Sriram’s assets. Before the hearing on the civil preliminary injunction, the government gave notice that it intended to call Dr. Sriram’s wife, Ms. Sriram, to testify. The government refused to provide assurance that it would not use Ms. Sriram’s testimony or the fruits of her testimony in the connected criminal action. Accordingly, Ms. Sriram asserted the spousal privilege. The government argued that the spousal privilege should not apply.
