Lawyers for the state have defended the redistricting plan, noting that the new map had bipartisan and near unanimous support.
In his filing Tuesday, Majestro said the redistricting map doesn't split counties, doesn't require any of West Virginia's congressional incumbents to run against one another, and preserves the former districts "as much as possible."
"Prior decisions of the court have held that small variances are acceptable when, as in this case, the state justifies those variances," Majestro said. "We think the issues and questions here are important enough for a full review."
Jefferson County officials and Cooper have 30 days to file a response to Majestro's statement with the Supreme Court.
"I believe the magnitude of the variance is way too large for the U.S. Supreme Court to uphold," Cooper said Tuesday night. "I will file a response after I've had a chance to read the entire statement."
Jefferson County officials could not be reached for comment.
The Supreme Court will later decide whether to affirm the U.S. District panel's decision, reverse it or request a full briefing on the appeal.
A lawyer for Senate President Jeff Kessler also signed on to the request for the Supreme Court's review on Tuesday.
Gov. Earl Ray Tomblin and Secretary of State Natalie Tennant joined a portion of Tuesday's appeal, which seeks to prevent the U.S. District Court from imposing its own congressional redistricting plan on the state.
