I recently taught a session at the magistrates’ conference about arrestable conditions of pretrial release. The session sparked a lot of discussion about the law surrounding pretrial conditions for in-custody defendants. It is well understood that when a defendant violates pretrial release conditions after being released from custody, the law allows several mechanisms for enforcement, including revocation of pretrial release, arrest of the defendant, and the setting of new, potentially stricter conditions of pretrial release. What’s less clear is (1) whether or not conditions of release are enforceable if a defendant has not yet been released, and (2) if they are, what tools judicial officials have for enforcement. This post addresses these questions.
