Sol Z. Rosen, a Washington trial lawyer who has accused the Virginia State Bar of discriminating against women, blacks and Jews, has been threatened with the loss of his Virginia law license by the agency he is challenging.

Rosen, who attacked the Virginia bar in a suit filed in U.S. District Court in Alexandria, has been ordered to appear before the Virginia Supreme Court in Richmond Jan. 8 to answer charges he violated a bar regulation.

In an unusual proceeding that was begun this summer, Rosen has been accused of violating a rule that allows lawyers who have practiced elsewhere for five years to practice in Virginia without taking a bar examination provided they work full time in the state. The complaint against Rosen alleges that he conducts most of his practice from a Washington office, although he has stationary with an Arlington letterhead.

Rose could not be reached for comment yesterday, but lawyer Philip J. Hirschkop of Alexandria, who is defending him, called the Virginia action "purely retaliatory." He said "They are just using this idiotic rule because he sued them."

"That's a damn fog and smoke screen," N. Samuel Clifton, executive director of the Virginia State Bar told the Associated Press when confronted with similar statements by Hirschkop. "It doesn't amount to a hill of beans. That's just Hirschkop's rhetoric," Clifton said to the AP.

Rosen's suit against the Virginia bar was dismissed by a federal judge, but the case is currently on appeal to the 4th U.S. Circuit Court of Appeals.

The bar's complaint against Rosen marks the second time this year he has been cited for alleged infractions of the Virginia bar's regulations.
