The US Supreme Court has agreed to hear a case brought by the families of five black people killed by police officers in Chicago.
The four men were shot by a police officer in the back as they walked away from a bar in April 2015.
A federal judge ruled last month that the police had acted within their rights when they opened fire.
The families of the five have argued that the officers used excessive force, and that they did not have the right to use lethal force in their encounters with the men.
The court agreed to review the case on Monday, and is expected to rule soon on whether to hear it.
“We believe that we have the strongest legal standing to bring this case,” said a spokesman for the family, Johnathan Ford, who declined to elaborate.
The lawsuit is being brought by three black families, including that of a man who was shot and killed by a Chicago police officer while in his car in March.
The officers who killed the man, 22-year-old Laquan McDonald, have been charged with murder and misconduct in office.
In its ruling, the court cited an internal review of the police shooting that concluded the officers were justified in their use of deadly force.
“The use of force by the police officers was justified and consistent with departmental policy,” Justice Clarence Thomas wrote.
“There was no other way to resolve the situation.”
A federal court has ordered the police department to pay the families $3.4m.
The decision could have significant ramifications for the use of body cameras by police.
The video was not released publicly, but the Associated Press reported that it shows officers shooting at McDonald as he ran from them with his hands up and one of the officers firing at him twice.
The Associated Press obtained the video through a Freedom of Information Act request.
