Banks have the right to refuse service if they consider customer transactions suspicious. Maybe he pays too little tax or he has a one-day partner. But sometimes refusals are unfair and groundless. And it can be difficult to argue, because the law gives the bank a wide margin of discretion. There's still hope for a lawsuit. If you have all the documents in your hands, and the bank - only suspicions, the success is almost guaranteed.
