In February 2016, during voir dire in a criminal trial, Minaldi failed to determine if jurors were qualified citizens and failed to deliver any preliminary instructions. At one point, she stopped the questioning of a witness discussing a computer application because she was ignorant of what a "drop-down menu" was. After the public defender made a motion for curative measures, Minaldi ordered the prosecutor to deliver preliminary instructions to the jury, stopping to complain to the prosecutor, "I have no idea what’s going on here. Get your act together." After the prosecutor and public defender jointly moved for a mistrial, the chief district judge removed Minaldi from the case and assigned it to Judge Donald Ellsworth Walter, who then declared a mistrial.[7]
Indefinite medical leave
In January 2017, the Clerk of the Western District of Louisiana confirmed that Minaldi had surrendered her entire docket of cases and had taken medical leave for treatment for alcoholism so severe that a colleague asked a court to rule she could not take care of herself.[8] It is not known on exactly what date she left.[9][8] Her leave ended when she took inactive senior status on July 31, 2017.[10][11]
