Baldwin, who is also a producer on the film, was charged with two counts of manslaughter in the death of "Rust" cinematographer Halyna Hutchins.
Though Baldwin's manslaughter case has been dropped, the actor still faces other legal woes as a result of the accidental shooting.
In early February, Hutchins' parents and sister filed a lawsuit against Baldwin, "Rust" producers and other crew members, accusing them of negligence and intentional infliction of emotional distress, among other charges.
Halls' hearing was the first to be conducted under the supervision of special prosecutors Kari Morrissey and Jason Lewis.
In her place, she appointed Morrissey and Lewis as special prosecutors.
