Federal judicial service
On April 26, 1994, President Bill Clinton nominated Parker to serve as a United States district judge the United States District Court for the Southern District of New York, to a seat vacated by Judge Leonard B. Sand, who assumed senior status on July 1, 1993. He was confirmed on September 14, 1994 by voice vote. He received his commission on September 15, 1994. His service as a district judge was terminated on October 18, 2001 when he was elevated to the court of appeals.

Parker was initially nominated to that court by President George W. Bush on May 9, 2001, to fill a seat vacated by Judge Ralph K. Winter, who assumed senior status on September 30, 2000. However, the Democratic-controlled United States Senate returned Parker's nomination just a few months later without considering it. Bush renominated him, along with many other previously returned nominees, on September 4, 2001. This time, the Senate confirmed Parker's nomination a little over a month later, on October 11, 2001, by a 100–0 vote. He received his commission on October 16, 2001. He assumed senior status on October 10, 2009.

The decision affirmed an earlier ruling by U.S. District Judge Naomi Reice Buchwald.
