Decision: Landon v. Plasencia, 459 U.S. 21 (1982).

Landon v. Plasencia arose after a lawful permanent resident returned from a short trip to Mexico during which immigration officials alleged that she attempted to assist undocumented people across the border.

The agency used an exclusion hearing

Immigration officials denied Plasencia admission after the trip. She sought habeas relief, arguing that her admissibility should have been litigated through deportation procedures with additional protections.

The statute permitted the entry inquiry

The Court held that the agency could determine in exclusion proceedings whether the returning resident was making an entry and whether she was excludable. The Court did not require the government to begin with deportation proceedings under the statute then in effect. Landon, 459 U.S. at 25–32. This is a historical distinction between exclusion and deportation; a current returning-resident case requires the present admission statute and procedure, not a mechanical transfer of the 1982 labels.

A returning resident retained due-process interests

The Court separated two questions: Which proceeding the statute allowed, and whether the hearing was fair. It rejected a right to identical treatment for returning and continuously present residents. But Plasencia’s interest in returning to her home, work and immediate family was weighty. The court had to weigh that interest, the risk of error and value of safeguards, and the government’s interests. Landon, 459 U.S. at 31, 34–35.

The adequacy question was remanded

The majority did not decide whether the hearing was constitutionally adequate. It identified concrete questions: Who bore the burden of proof, whether less than eleven hours’ notice gave a realistic preparation opportunity, and whether the waiver of representation was understood. It also required consideration of the government’s burden from added safeguards. Landon, 459 U.S. at 35–37. Justice Marshall would have found a due-process violation on the existing record; that was his separate view, not the majority’s disposition.

Key takeaways

• Determine whether the trip legally constituted an entry under the governing statute.
• Do not equate the procedural label with the amount of process constitutionally due.
• Develop the resident’s family, home, work, and community ties.
• Identify the specific safeguard that would reduce the risk of error.
