A federal appeals court panel on Tuesday unanimously voted to uphold the Seattle Police Department's policy that regulates the use of force by officers, dismissing the argument that it infringed on the cops' Second Amendment rights.

"The City of Seattle has a significant interest in regulating the use of department-used firearms by its police officers, and the [Use of Force Policy] does not impose a substantial burden on the Second Amendment right to use a firearm for the core lawful purpose of self-defense," District Judge William Hayes wrote on behalf of a three-judge panel that presided the court case  Mahoney vs. City of Seattle .

The police force adopted the UF Policy in 2012 as part of its reform agreement with the Justice Department, which required officers to use "objectively reasonable force, proportional to the threat or urgency of the situation" only when necessary as well as de-escalation techniques when possible, the Hill reports.

A group of about 125 officers filed the lawsuit , claiming the city's new rule violated their Second Amendment right to use their service weapons in cases of self-defense.
