Background

Olisar Neptaly Diaz, a Guatemalan citizen, applied for cancellation of removal—a form of immigration relief that allows certain undocumented immigrants to remain in the United States if they can demonstrate that their departure would cause exceptional and extremely unusual hardship to qualifying relatives (U.S. citizens or lawful permanent residents). An immigration judge denied Diaz’s application, finding that he had failed to meet this stringent standard. The Board of Immigration Appeals affirmed the denial, and Diaz then sought review in the Ninth Circuit Court of Appeals.

In his petition, Diaz argued that the immigration judge and BIA had misapplied the legal standard for “exceptional and extremely unusual hardship” and had failed to properly consider evidence concerning his qualifying relatives’ serious medical conditions and financial circumstances. He also raised a due process challenge, contending that the agency had engaged in speculation regarding his daughter’s medical condition. The Ninth Circuit panel—Judges Owens, Collins, and Sung—was asked to decide whether the agency’s findings were supported by substantial evidence and whether any legal or constitutional errors had occurred.

The Court’s Holding

The Ninth Circuit upheld the denial of cancellation of removal. The court emphasized that substantial evidence supported the BIA’s determination that Diaz had not demonstrated the required level of hardship. The legal standard requires showing hardship that is “substantially beyond the ordinary hardship that would be expected when a close family member leaves the country”—a demanding threshold. The panel found Diaz’s contentions that the agency used the wrong legal standard or failed to consider hardship evidence to be unsupported by the appellate record.

Regarding jurisdictional issues, the Ninth Circuit clarified that when cancellation of removal is denied, federal courts have authority to review only constitutional claims and questions of law, not factual determinations about relatives’ medical conditions or financial circumstances. This jurisdictional limitation, established by federal statute and confirmed by the Supreme Court in Wilkinson v. Garland, prevented the court from independently reviewing the agency’s findings on these critical issues.

The court also rejected Diaz’s due process claim. To prevail on such a claim, a petitioner must demonstrate both a violation of rights and resulting prejudice. The court found that Diaz had not shown error in the agency’s handling of his daughter’s medical condition, thus the due process claim failed. The motion to stay removal was denied as moot, and the petition for review was denied in part and dismissed in part.

Key Takeaways

  • Cancellation of removal requires proof of hardship substantially exceeding the ordinary distress of family separation—a demanding burden that courts review under the deferential substantial-evidence standard.
  • Federal courts lack jurisdiction to review factual findings in cancellation cases; they can only review constitutional claims and pure legal questions.
  • Due process claims in immigration contexts require showing both a procedural violation and prejudicial impact; mere disagreement with factual conclusions is insufficient.
  • Hardship evidence regarding medical conditions and finances must be carefully documented and presented; judicial speculation alone cannot establish error.

Why It Matters

For California immigration practitioners, this decision reinforces the extremely limited scope of federal appellate review in cancellation-of-removal cases. The court’s jurisdictional holding means that even if a practitioner believes an immigration judge or the BIA misweighed evidence or made clearly erroneous factual findings, an appellate court cannot second-guess those determinations. This places enormous importance on creating a complete factual record at the administrative level, with detailed medical evidence, financial documentation, and testimony regarding hardship.

The decision also clarifies that generic due process arguments—asserting the agency “speculated” about medical facts—will not survive appellate review unless the petitioner can point to specific procedural violations. For California-based immigration attorneys representing clients seeking cancellation of removal, the takeaway is clear: the battle is largely won or lost before the immigration judge, and appellate options are confined to legal error and constitutional violations. Practitioners must invest heavily in developing the factual record and establishing the burden before turning to appellate review.
