Two lawyers in the D.C. Corporation Counsel's office were fired yesterday, about three weeks after it was disclosed that the city prosecutor's office was trying to collect unpaid parking ticket fees from the two men.

A spokesman for the corporation counsel's office said C. B. Jones and Victor O. Frazer, both assistant corporation counsels in the law enforcement section, were discharged from their duties at the close of business yesterday. The spokesman refused to comment on the reason for the dismissals.

The dismissals can be appealed to the mayor or through normal civil service grievance procedures, depending on the circumstances of each case.

It was recently discovered that Jones and Frazer, along with three other lawyers who are or were employed in the law enforcement section, owed an average of $300 to $500 in fines for parking violations. Most of the tickets were issued in the vicinity of the D.C. Superior Court, where the offices of the law enforcement division are located.

As of March 10, it was learned, all the lawyers except for Jones and Frazer had paid the fines. At that time, a source confirmed the corporation counsel's office was trying to collect the money from Jones and Frazer.

Jones, who has worked in the corporation counsel's office since 1973, could not be reached for comment late yesterday, nor could Frazer, who has worked there since 1974.
