The lawyer doesn't want to touch it. Upper management is nervous. They want you to handle the matter but with very close supervision. There is a tight deadline. Litigation is likely. The in-house experts are inexperienced. There are conflicting standards or rules. Information is withheld. They forget to tell you things. The atmosphere is toxic. There is a huge lack of trust. Neither side is admirable. You appear to be a convenient scapegoat. Mission creep is creeping. There are factions within factions. You'll barely have time to think.
You smell a rat.
