A Fairfax County Circuit Court judge has dismissed a $100,000 lawsuit that former Vienna police chief Zed L. Childress filed against town officials he said illegally conspired to fire him in June 1984.

A town spokeswoman said Judge Thomas J. Middleton threw out the complaint filed two months after Childress was fired by the Town Council following reports of widespread dissatisfaction within the 33-officer police force.

John F. Gionfriddo, the town attorney, said Childress has 21 days to refile a defamation of character complaint and take his breach of agreement allegation to the town's grievance committee.

Childress, a 23-year police veteran, had replaced Vernon L. Jones as chief of the department in August 1983 after Jones was fired by the Town Council without explanation.

In his suit, Childress had named as defendants Mayor Charles A. Robinson Jr., Town Manager Brackenridge H. Bentley and the members of five-member Town Council. He alleged that they conspired against him by meeting illegally and in secret, and defamed his character, preventing him from getting another job.

Gionfriddo declined to comment on the ruling, saying he did not consider the matter closed.

Childress and his attorney, Gary Davis, also declined to comment.
