Background

Ruth Maria Polanco Valle had been held by immigration authorities for more than nineteen months while removal proceedings tied to a Texas aggravated-kidnapping conviction continued. Both sides agreed that the mandatory-detention statute applied, which ordinarily provides no statutory right to bond.

She sought habeas relief under the Fifth Amendment. The government also argued that she had not exhausted review of an earlier custody decision, but later filings showed that she timely appealed and the Board of Immigration Appeals had ruled.

The Court’s Holding

The court held that the length and uncertain future duration of detention made continued custody without a meaningful bond hearing unconstitutional. The government’s interest in enforcing immigration law remained substantial, but a routine bond hearing imposed only a modest administrative cost.

The court denied the government’s dismissal motion, granted habeas relief, and ordered a hearing within 14 days. At that hearing, the government must establish danger or flight risk by clear and convincing evidence, with advance notice and counsel permitted to attend.

Key Takeaways

  • Mandatory detention can still raise an as-applied due-process problem when it becomes prolonged.
  • Nineteen months plus an unresolved appellate process weighed strongly toward a hearing.
  • An exhaustion defense fails when the record shows timely administrative review.
  • The remedy was a new bond hearing, not automatic release.

Why It Matters

California immigration practitioners can use the decision as a roadmap for fact-specific prolonged-detention challenges. The strongest record will show elapsed custody, likely future duration, completed administrative steps, and the minimal burden of providing an individualized hearing.
