What do you mean unclear? The ruling says that certain of the tariffs were always illegal.

It's 100% clear, and even if it weren't the government already conceded that the tariffs are refundable to get this far. If the tariffs were not refundable, that would mean that the injury from them is irreparable, and they would have had to be enjoined pending the decision.
