The military judge in Marine Sgt. Clayton J. Lonetree's court-martial for espionage refused yesterday to dismiss or reduce any of the charges of spying and other crimes lodged against the former guard at the U.S. Embassy in Moscow.

The judge, Navy Capt. Philip F. Roberts, dismissed a motion by two defense attorneys that alleged the government was accusing Lonetree of too many counts for each alleged offense.

Roberts also rejected a defense motion that alleged the government has prevented Lonetree from having a speedy trial.

"The court could possibly agree if it were shown the government had shown malice," Roberts said. Prosecutors had blamed delays on Lonetree's defense lawyers.

Defense lawyers had said the government delayed the case and hindered their efforts by failing to turn over evidence and acting slowly in requesting visas so military defense lawyers could travel to Moscow and Vienna.

Lonetree, 25, of St. Paul, Minn.,is accused of letting his love affair with a Soviet translator turn him into a spy. He faces life in prison, but his lawyers say he turned over nothing of value to the Soviets.

Lonetree is charged with revealing the identities of Central Intelligence Agency agents at the Moscow embassy under the so-called agent identification act.
