A unanimous decision made by the highest criminal court in Texas upholds Wichita Falls' gang injunction.
The Court of Criminal Appeals is upholding the injunction and the conviction of Mario Martinez for violating it.
The city has multiple gang injunction zones.
In these areas, known gang members are prohibited from doing several acts, including associating with other gang members.
Martinez was convicted for flashing gang hand signs and wearing gang clothing.
Martinez had argued the injunction violated his constitutional rights.
Law enforcement arrested Martinez back in 2008.
