(CNN) Gun manufacturer Remington is asking the US Supreme Court to hear a lawsuit involving the company and families of Sandy Hook victims.

In a filing dated Friday , Remington asked the Connecticut Supreme Court for a motion of stay as it petitions the high court to hear its argument. Remington is asking the court to decide on the state's interpretation of a federal statute that grants gun manufacturers immunity from any lawsuit related to injuries that result from criminal misuse of their product.

The case could determine the degree to which gun manufacturers are liable for the marketing of their products. The Connecticut lawsuit is believed to be the first of its kind to reach the discovery phase after the enactment of the Protection of Lawful Commerce in Arms Act in 2005, which grants immunity to manufacturers and is at the center of Remington's motion.

Remington manufactured the Bushmaster AR-15 rifle that the 20-year-old gunman used in the 2012 shooting at the Sandy Hook Elementary School. Twenty children and six adults were killed in the massacre in Newtown, Connecticut, in one of the deadliest mass shootings in modern US history.

Following a state court ruling last month, Remington says it's heading to the US Supreme Court because "the basis for jurisdiction in the Supreme Court is this court's decision on an important federal question that conflicts with a decision of a United States court of appeals."
