John McConnell, an attorney for the Sons of Confederate Veterans said the ruling confirms that "the government cannot step into an issue and silence one side while endorsing the viewpoint of the other side," according to the Dallas Morning News.
The NAACP condemned the ruling.
“This is a sad day for African-Americans and others victimized by hate groups in this state,” said Gary Bledsoe, president of the Texas NAACP.
The three-judge appeals court panel overturned a decision by a U.S. District Court judge, who ruled that the First Amendment doesn't require Texas to print a group's flag on property controlled by the government.
Nine other states issue Confederate flag license plates, including Georgia, according to the Dallas Morning News.
