Third-degree murder charges were reinstated Thursday against Derek Chauvin after a series of appellate issues. Here's a timeline of what happened.

June 3: Minnesota Attorney General Keith Ellison's office adds a charge of second-degree murder.

Oct. 22: District Judge Peter Cahill dismisses third-degree murder count, citing state law saying that "a third-degree murder charge can be sustained only in situations in which the defendant's actions ... were not specifically directed at the particular person whose death occurred."

Feb. 1, 2021: The Minnesota Court of Appeals upholds the third-degree murder conviction of ex-Minneapolis police officer Mohamed Noor in the 2017 shooting death of Justine Ruszczyk Damond. In the 2-1 ruling, the Appeals Court rules that third-degree murder can apply even when conduct or force is directed at a single person.

Feb. 25: Noor's attorney asks the state Supreme Court to overturn his third-degree murder conviction.

March 1: Oral arguments over Cahill's third-degree murder charge denial take place before the Court of Appeals. The focus is whether the Appeals Court ruling is binding while the Supreme Court considers whether to hear Noor's case. The Supreme Court announces it will hear Noor's appeal.

March 5: The Court of Appeals rules that Cahill erred in not granting the state's motion to reinstate the charge, saying that its earlier ruling is binding.

March 9: Chauvin's attorney Eric Nelson asks the Minnesota Supreme Court to review the Appeals Court order.
