## Facts

- Dennis Bell, a juvenile, was arrested on September 30, 1977, and taken to the Pima County Juvenile Court Center.
- The referral offense was listed as possessing stolen property.
- On October 3, 1977, the State filed a delinquency petition alleging Bell possessed stolen property valued at $100 or more.
- At a detention hearing on October 4, 1977, Bell, his mother, and counsel requested (1) reasonable bail and (2) a probable-cause hearing requiring the State to show probable cause that Bell committed a delinquent act.
- A juvenile court referee denied bail and denied a probable-cause hearing, recommending continued detention based on lack of custodial supervision and perceived danger if released.
- A juvenile court judge affirmed the denials and ordered Bell detained pending the adjudicatory hearing.
- Bell sought special-action relief in the court of appeals; before appellate argument, the adjudicatory hearing was set, making Bell’s request for immediate release moot.

## Issues

1. Whether the Fourth Amendment requires a judicial determination of probable cause before a juvenile may be detained pending an adjudicatory hearing.
2. Whether a juvenile detained pending adjudication has a constitutional right to bail equivalent to an adult criminal defendant.

## Decision

- The court addressed the merits despite mootness because the issue was capable of repetition yet evading review and of statewide importance.
- The court held that a neutral judicial determination of probable cause is a constitutional prerequisite to continued pre-adjudication detention of a juvenile.
- The court concluded the juvenile court’s process was deficient where detention was ordered without an adequate factual showing supporting probable cause and where a probable-cause hearing was denied.
- The court declined to recognize an across-the-board right to traditional bail in juvenile proceedings.
- The court held that detention under Arizona Juvenile Rule 3(b) can function as a substitute for bail if applied with due process, including a probable-cause determination and consideration of detention factors.
- The court denied Bell’s request for specific relief because his claim for immediate release was moot.

## Legal Principles

- The Fourth Amendment requires a judicial determination of probable cause as a prerequisite to extended restraint of liberty following arrest, including in juvenile detention pending adjudication.
- The constitutional need for a probable-cause determination does not turn solely on the short duration of juvenile detention before adjudication.
- A full evidentiary hearing is not required in every case; the Constitution requires sufficient factual material reviewed by a neutral judicial officer to support a probable-cause finding for detention.
- Traditional bail is not constitutionally required in juvenile proceedings where a detention framework provides a constitutionally adequate alternative, including due process protections and a probable-cause determination under Rule 3(b).

## Conclusion

The court held that juveniles may not be detained pending adjudication without a neutral probable-cause determination, and that Arizona’s juvenile detention rule may serve as a functional substitute for bail only when used with due process safeguards, including an adequate factual basis establishing probable cause.
