Supreme Court of the United States, Bittner v. United States (2023)
“ Congress said that penalties for certain willful violations may be measured on a per-account basis. Congress said that a person may invoke the reasonable cause exception only on a showing of per-account accuracy. But the one thing Congress did not say is that the government may impose nonwillful penalties on a per-account basis. Conspicuously, the one place in the statute where the government needs per-account language to appear is the one place it does not. In the end, the government’s per-account theory faces not just a single expressio unius challenge but two. ”
