How Judge Castillo decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In Moya-Cabrera v. Warden, Castillo recommended granting an immigration habeas petition in part after finding detention under 8 U.S.C. § 1226(c) had become unreasonably prolonged. She recommended an individualized bond hearing with the government bearing the burden, rather than immediate release.

“unreasonably prolonged, and that due process now requires an individualized bond hearing.”

In a Social Security appeal, Castillo held that the ALJ had not connected the cited treatment evidence to the rejection of Dr. Bonilla’s opinion. She remanded because the omitted work limitations could affect the disability finding.

“Critically, the ALJ does not draw a logical bridge between the evidence cited and the medical opinion”

Procedural preferences

Requests for volunteer civil counsel must satisfy the exceptional-circumstances test; ordinary difficulties of incarceration, limited legal training, and indigence do not suffice when the litigant can articulate the claims.

“circumstances exist warranting the appointment of counsel. Rand, 113 F.3d at 1525.”

In Bowerman, Castillo denied a self-represented litigant’s request for electronic filing because she had not shown that conventional filing by mail was unavailable. The request could be renewed on a sufficient showing.

“the Court DENIES the request to file electronically (Doc. 10),”

Cautions

A prisoner subject to the three-strikes bar must allege specific facts showing a genuine and proximate danger at the time of filing; conclusory or historical allegations do not open the imminent-danger exception.

“Plaintiff’s allegations do not satisfy the imminent danger exception to section 1915(g).”

In Ruslanov, Castillo recommended dismissal of a habeas case as duplicative of an earlier action and proposed treating the petitioner’s pending requests as moot. The district judge had not adopted that recommendation in this order.

“Respondents’ motion to dismiss, (Doc. 13), be GRANTED;”
