A panel of seven Navy officers sentenced Cmdr. Reginald E. Newman to forfeit $2,000 a month in pay for the next 10 years and fined him $10,000 yesterday for lying about his actions in recruiting Navy physician Cmdr. Donal M. Billig. Newman also was dropped to the bottom of the promotions list and will receive an official letter of reprimand.

Newman, 53, was found guilty Tuesday by the same panel of two counts of perjury, two counts of making false official statements and one count of dereliction of duty. He was acquitted of two perjury charges. He faced a maximum sentence of 20 1/2 years in prison.

Newman supervised recruitment of doctors when Billig joined the Navy in 1982.

Separate court-martial proceedings against Billig, who faces manslaughter charges in connection with the deaths of five patients at Bethesda Naval Hospital, are in their third week.

Newman, who has 35 years of Navy service, is paid $4,581 a month, according to a Navy spokesman.

The forfeiture applies only to active-duty pay and will not affect his military retirement pay, the spokesman said.

A Navy spokesman said if Newman retired, he would be free of the pay forfeiture.

Newman's attorney, Lt. Cmdr. Irving Warden, would not specify whether Newman will resign or appeal, but said only that he would "follow the system." Newman is able to appeal only after the panel's decision is reviewed by Navy officials.

Newman, who before his court-martial was bumped from his captain's rank to commander and relieved of his post, will not be lowered in rank by the sentence. Since being relieved of his command, Newman has been working on the staff of the Navy Medical Command supply department, and has been assigned to duty at Bethesda.
