A Supreme Court spokeswoman said Justice Antonin Scalia was involved in a minor car accident while driving to work.

Scalia was not injured in the accident, which happened while he was driving on the George Washington Parkway, court spokeswoman Kathy Arberg said.

The 75-year-old Scalia was on the bench when the Tuesday morning session began.

The high court is hearing arguments on whether to end a massive sex discrimination lawsuit against Wal-Mart claiming that the world's largest retailer favors men over women in pay and promotions.

No other information about the accident was available.
