Wal-Mart issued a federal court filing claiming that Tracy Morgan is responsible for the injuries he suffered when a Wal-Mart truck hit his limo bus in June, leaving him in critical condition and killing his longtime friend.

The fatal crash occurred on June 7 when a speeding Wal-Mart truck slammed into Morgan's Mercedes limousine, which was carrying him and four others on the New Jersey Turnpike. Comedian James "Uncle Jimmy Mack" McNair died in the collision, while the other passengers were seriously injured, CNN reported.

The 45-year-old "30 Rock" star suffered from broken ribs, a broken nose, a broken femur and a broken leg in the accident. He was hospitalized for two weeks, and then he spent three weeks recovering in a rehabilitation center. He also spent several weeks undergoing intensive outpatient treatment.

In July, the famous comic and the other surviving victims filed a lawsuit blaming the multiple vehicle crash on Wal-Mart for their careless and negligent ownership of the vehicle. According to the suit, the retailer has a custom and practice of recklessly allowing its drivers to operate its trucks for long periods of time without adequate rest, Reuters reported.

The complaint also states that an Arkansas-based Wal-Mart store knew or should have been aware that its truck driver, Kevin Roper, was awake for over 24 hours before the accident and was restricted by federal regulations from operating the vehicle. The suit also claims that Roper drove over 700 miles prior to beginning his work shift.

Wal-Mart issued a 28-page response to the lawsuit on Monday, claiming that the injuries were "caused, in whole or in part, by plaintiffs' failure to properly wear an appropriate available seat belt restraint device," reports CNN. The retail giant also stated that the plaintiffs "acted unreasonably and in disregard of plaintiffs' own best interests" by failing to buckle up.

The filing also states that damages that Morgan and the other plaintiffs suffered were not caused by the company or its affiliated employees. Instead, Wal-Mart argued that injuries "may have been caused by third parties over whom Walmart had no control."

Furthermore, Wal-Mart is requesting a trial by jury.

An attorney representing Morgan and the other plaintiffs called Wal-Mart's response "surprising and appalling," reports The Associated Press.

"It's disingenuous," attorney Benedict Morelli said. "It's not what they said they were going to do initially, which was take full responsibility. I'm very upset, not for myself but for the families I represent."
