(KTVI)- Police in Ferguson will no longer be able to force non-law breaking protesters to keep moving on sidewalks. On Monday, a federal court ruled that the so-called “Five Second Rule” that was enforced during the Ferguson protests is not constitutional.

In September, the ACLU filed a lawsuit challenging that the law is not allowed under the First Amendment.

Federal Judge Catherine Perry granted a preliminary injunction Monday afternoon in the lawsuit Mustafa Abdullah v. Saint Louis County et al., regarding the “five-second rule.” Following the shooting death of Michael Brown, an order was given to protesters to keep moving. If a protester was in one place for at least five seconds, they could be arrested.
