The ACLU says it filed notice of appeal Wednesday. The move comes after 2nd District Judge Ernie Jones ruled last month that an injunction first ordered in 2010 should be permanent.
The injunction also sets an 11 p.m. curfew for Ogden Trece members and makes it illegal for them to carry guns or graffiti tools.
An attorney partnering with the ACLU, David Reymann, called the injunction an "unprecedented" infringement on constitutional rights.
Weber County asked for the injunction to curb criminal activity of a gang authorities believe has more than 350 members.
The U.S. Supreme Court previously refused to suspend the injunction.
