Can I challenge mandatory detention with a Joseph hearing?

2 min read · May 17, 2026

Yes — under Matter of Joseph, 22 I&N Dec. 799 (BIA 1999), a detained noncitizen can demand a hearing to determine whether INA § 236(c) mandatory detention actually applies, and if not, become eligible for a bond hearing.

INA § 236(c) strips the immigration judge of jurisdiction to set bond when DHS detains a noncitizen on certain enumerated grounds — most aggravated felony convictions, controlled-substance offenses, multiple CIMTs, certain firearm offenses, and others. The statute is harsh: there is no bond, no release, no individualized hearing on flight risk or danger. But the categorical-approach doctrine and Matter of Joseph together give the respondent a powerful tool to challenge whether mandatory detention actually applies to their conviction.

What a Joseph hearing decides

A Joseph hearing is held before the immigration judge to determine whether DHS is substantially likely to prevail on the charge of mandatory detention. If DHS cannot meet that standard — typically because the underlying conviction does not categorically match the federal generic definition — the respondent becomes a § 236(a) discretionary-detention case and a regular bond hearing is held.

How the categorical-approach defense works

Under Mathis v. United States, 579 U.S. 500 (2016) and Descamps v. United States, 570 U.S. 254 (2013), the judge compares (a) the elements of the statute of conviction with (b) the elements of the federal generic offense. If the state offense is categorically broader — sweeping in conduct that the federal definition would not — the conviction does not qualify as a § 236(c) trigger, even if the actual conduct would.

Examples we have used to win Joseph hearings:

• California Health & Safety Code § 11352 (transport of a controlled substance) — has been held to be overbroad relative to the federal definition because it includes solicitation, which is not a federal-generic drug-trafficking element. Rendon v. Holder, 764 F.3d 1077 (9th Cir. 2014).
• California Penal Code § 459 (burglary) — overbroad relative to the federal generic burglary because it does not require unlawful entry. Descamps directly.
• Most state DUI statutes — not aggravated felonies and not CIMTs under most circuit precedent.

What a Joseph win actually gets you

A successful Joseph motion does not release the respondent — it converts the case from § 236(c) to § 236(a). The immigration judge then holds a bond hearing where the respondent must show by clear and convincing evidence (in the Ninth Circuit, under Singh v. Holder, 638 F.3d 1196 (9th Cir. 2011)) that they are not a flight risk or danger. Bond can issue in the range of $1,500 to $25,000 depending on the equities.

Timing in the Ninth Circuit

In the Ninth Circuit, Rodriguez v. Marin, 909 F.3d 252 (9th Cir. 2018) and related litigation entitle prolonged-detention respondents to a bond hearing every 6 months even where mandatory detention initially applied. This is a separate procedural protection from Joseph.

How we handle this

The first move when a mandatory-detention case comes in is the certified court records — the charging document, plea form, judgment, sentencing order. We run the categorical-approach analysis on every charge. Where the statute is divisible, we apply the modified categorical approach to identify the specific conduct of conviction. The Joseph motion is the filing; the records analysis is the case. We have brought clients home from Adelanto in 3–6 weeks using this approach when the alternative was months of detention.
