An indictment is sometimes filed under seal and kept sealed until the defendant appears. The indictment is kept sealed so as to not tip off the defendant. In some districts, indictments are initially sealed as a matter of course. Once the defendant has appeared, the indictment can be unsealed. If the defendant cooperates with the government’s prosecution of others, who may be defendants in the same case or defendants in cases with other case numbers, then the case may re-main sealed because of cooperation. Sometimes an indictment remains sealed after the defendant appears because no one thought to unseal it.
In a multi-defendant case, it is possible to seal the prosecution against one defendant while the prosecution against another defendant is not sealed. For this project, only cases sealed as to all defendants were counted as sealed cases. In a few of these, the court kept the case sealed until all defendants appeared, which presumably would require either the explicit or implicit consent of those defendants who did appear.
Sometimes the government asks the court to dismiss a sealed indictment against a defendant who has not yet appeared. Perhaps the government has decided not to prosecute the defendant after all, or the government has decided to prosecute the defendant with a different indictment or in a different jurisdiction. In a few cases, the sealed indictment was transferred. It is not clear whether such indictments should remain sealed permanently.
