AZ SB1311

Amends Arizona law regarding witness attendance in criminal proceedings by replacing language about "disobedience to subpoena" with "failure to comply with subpoena" and removes a provision allowing defendants to recover $100 in civil damages from witnesses who fail to appear.

Establishes a new definition of "material witness" as a witness whose testimony is necessary for a fair determination of an issue in a criminal case or grand jury proceeding.

Authorizes courts to require material witnesses to post secured or unsecured appearance bonds and allows law enforcement to detain witnesses who willfully fail to comply with subpoenas or court orders.

Requires that detained material witnesses be held separately from criminal defendants, provides protections for juvenile witnesses, and mandates the witness be brought before court on the same or next court date.

Mandates material witnesses be deposed or testify within three days of a detention order and requires their automatic release from detention if not deposed within that timeframe.
