A federal judge yesterday ordered all papers connected to a lawsuit filed by a former CIA agent against another agency employe sealed from the public on the grounds that the quarrel might disclose national security secrets.

District Court Judge D. Dortch Warriner, sitting in Alexandria, responded to requests by government lawyers and issued the sweeping protective order.

Justice Department lawyer Stanley Wright sought the order yesterday, telling Warriner that harmful national secrets might be disclosed in pretrial motions and papers.

The nature of those secrets has never been revealed in court.

C. Philip Liechty, the ex-CIA agent who filed the $2 million slander suit against his former colleague, Robert E. Bodroghy, has said outside of court that CIA officials had "covered up" attempts by Korean officials to bribe American congressmen in the early 1970's.

The CIA and Bodroghy have declined comment on the statement.

Yesterday Liechty's attorney Thomas Fortune Fay argued against the issuance of the protective order, claiming the government had never made a "factual demonstration" of what secrets it wanted kept from public view. m

Warriner told Fay that he would rather government lawyers make the decision as to what should be protected from exposure than leave the decision "up to you and your client."

The original slander suit was filed by Liechty in connection with a bitter child custody fight he is having with his estranged wife in Montgomery County. Fay said he will appeal.
