CA AB127

Requires magistrates to examine a declaration of probable cause before issuing an arrest warrant, made by a peace officer or a public prosecutor's office employee when the defendant is a peace officer.

Permits declarations to be submitted as written sworn statements, oral statements under penalty of perjury (recorded and transcribed), or transmitted electronically via facsimile, email, or computer server with digital or electronic signatures.

Allows magistrates to examine the declarant and witnesses under oath before issuing the warrant, and requires magistrates to verify receipt of all pages, legibility, and signature authenticity for electronically transmitted documents.

Establishes that warrants of probable cause for arrest have the same authority and time limitations as arrest warrants under existing law but do not initiate complaint or preliminary examination processes.

Requires arresting agencies to file a certificate of service with the court within a specified timeframe containing the arrest date, time, location, defendant name, and incarceration location.
