Landon v. Plasencia: A Returning Resident’s Hearing Must Satisfy Due Process

Published May 25, 2026

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 Constitution did not require the government to begin with deportation proceedings.

A returning resident retained due-process interests

A permanent resident’s ties to the United States do not vanish during a brief absence. The hearing therefore had to provide the process due under the balancing of the individual interest, risk of error and value of safeguards, and governmental burdens.

The adequacy question was remanded

The Court did not decide on the existing record whether Plasencia’s hearing satisfied due process. It remanded for the lower courts to apply the proper framework to the procedures actually provided.

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.
