SANTA FE, N.M. — A New Mexico judge has upheld her decision to dismiss an involuntary manslaughter charge against Alec Baldwin in the fatal shooting of a cinematographer on the set of a Western movie.

In a ruling Thursday, state District Court Judge Mary Marlowe Sommer stood by her July decision to dismiss an involuntary manslaughter charge against Baldwin. She said prosecutors did not raise any factual or legal arguments that would justify reversing her decision.

“Because the state’s amended motion raises arguments previously made, and arguments that the state elected not to raise earlier, the court does not find the amended motion well taken,” the judge wrote, adding that the request was also untimely.

A spokesperson for Baldwin’s lawyers said Friday that they had no immediate reaction to the decision.

Special prosecutor Kari Morrissey said she disagrees with the court’s analysis and will appeal the ruling. Morrissey was appointed by the Santa Fe district attorney to take over the case.
