The names of three Washington lawyers--a defense attorney, a veteran prosecutor and a Justice Department official--have been sent to the White House as candidates to fill a vacancy on the D.C. Superior Court, it was announced yesterday.

The names of Richard K. Gilbert, J. Ramsey Johnson and John McAdam Mott were forwarded by the D.C. Judicial Nomination Commission for consideration by President Clinton in selecting a nominee for the seat vacated by the retirement of Judge Truman Morrison III.

The commission said Gilbert, 51, has been in private practice specializing in criminal defense since 1982. Before that, he served in Stuttgart, Germany, in the U.S. Army Judge Advocate General Corps as legal assistance officer, prosecutor, defense counsel and senior defense counsel.

He received an undergraduate degree from Vanderbilt University in 1970 and is a 1977 graduate of the Georgetown University law school.

Johnson, 54, a former interim U.S. attorney in the District, has served since January 1999, as a special counsel to Wilma A. Lewis, the District's U.S. attorney.

Johnson, who received an undergraduate degree from Georgetown University in 1968, graduated from the Antioch School of Law in 1976 and was appointed an assistant U.S. attorney later that year. Since then, he has served in all sections of the prosecutor's office here, including a period as principal assistant to then-U.S. Attorney Eric H. Holder Jr.

Mott, 40, is deputy chief of the civil rights division in the Criminal Section of the Department of Justice, where he also serves as professional responsibility officer.

He was acting chief of the criminal section from July 1998 to last February, and before that was a senior trial attorney in the criminal section.

Mott is a graduate of Dartmouth College and the Northeastern University School of Law and was a staff attorney from 1988 to 1995 in the District's Public Defender Service.
