Why cases are sealed
The seal prevents the target from learning about the investigation prematurely, gives DOJ time to review evidence, and protects the relator's identity early in the process.
How long it lasts
Initial seal periods are typically 60 days but are routinely extended — often for a year or longer while the government investigates complex fraud.
What relators should do
Follow counsel's guidance on confidentiality, avoid discussing the matter on employer systems, and be patient — silence during seal does not mean the case is inactive.
