A New Mexico judge on Friday rejected Alec Baldwin's bid to dismiss an involuntary manslaughter charge for the 2021 shooting of cinematographer Halyna Hutchins, opening the way for an unprecedented trial of a Hollywood actor for an on-set death.

Baldwin's lawyers argued at a May 17 hearing that a grand jury indictment of the actor was "a sham" as prosecutors failed to tell jurors they could question defence witnesses and stopped them hearing evidence helpful to the actor's case.

Among her arguments in a court filing, district court Judge Mary Marlowe Sommer said she did not find prosecutorial bad faith in the grand jury, nor error in jury instructions and prosecutors adequately advised jurors regarding a letter from Baldwin's legal team listing defence jurors they could call.

"The court finds no error in the actions taken by the prosecutor vis-a-vi the reading of the evidence letter," Marlowe Sommer said in the filing

The actor now faces a July 10 trial.

Hutchins was shot with a live round after Baldwin pointed a gun at her as she set up a camera shot on a movie set near Santa Fe, New Mexico. The "30 Rock" actor maintains he did not pull the trigger, an assertion that has become central to the case.

Much of the differences between prosecution and defence positions are factual disputes and that is the type of case juries are meant to decide, said business and entertainment trial litigator Tre Lovell.

At trial, Baldwin’s legal team must convince Santa Fe jurors there was a cascading failure in set firearms safety before the weapon was put in Baldwin’s hand,

Special prosecutor Kari Morrissey has argued in court filings that Baldwin broke firearm safety rules by pointing the gun at Hutchins, cocking it and pulling the trigger.

Sommer sentenced "Rust" armorer Hannah Gutierrez to 18 months prison in April after a Santa Fe jury found her guilty of involuntary manslaughter for loading the live round into the reproduction Colt Single Action Army revolver Baldwin was using. (Reuters)
