Landon v. Plasencia

Plasencia (plaintiff/respondent), a permanent resident alien since 1940 married to a U.S. citizen, briefly traveled to Mexico and helped six nationals attempt to enter the U.S. illegally; INS detained her at the border for an exclusion hearing, where a judge found by clear and convincing evidence that she had knowingly aided the illegal entry attempt, resulting in her exclusion. She raised several due process objections to the hearing's procedures, and the Supreme Court granted certiorari.
