The 30 Rock star's close pal, fellow comic James 'Jimmy MACk' MCNair, was killed on 7 June, 2014, when a truck driven by Wal-Mart employee Kevin Roper collided with a limousine carrying the two funnymen and friends in New Jersey. The accident left Morgan and two other passengers seriously injured.

Morgan, who is still in recovery, launched a federal negligence lawsuit against Wal-Mart executives last summer (14), and in May (15), the two parties announced they had reached a confidential settlement.

Lawyers for both sides subsequently asked court officials to keep the papers under wraps, and on Tuesday (07Jul15), the motion was approved by U.S. District Judge Michael Shipp

In a written ruling, obtained by EntLawDigest.com, Shipp states: "Although the public may be interested in this case, the public has no legitimate interest in gaining access to this confidential information, as this is a case between private parties."

Driver Roper, who was not named as a defendant in Morgan's lawsuit, faces criminal charges over the collision. He has pleaded not guilty to one criminal count of death by auto and four counts of assault by auto.

Comedian MCNair's relatives previously accepted a $10 million (£6.25 million) payment from Wal-Mart bosses to settle their wrongful death suit.
