A special Justice Department committee that studied the U.S. marshal's officer here has found evidence of deficiencies in management, supervision and training, and an "unusually high number of disciplinary proceedings against blacks."

In addition, the panel found evidence that delays in resolving Equal Employment Opportunity complaints, and harassment of employees filing such complaints, exist in the U.S. Marshal's Service throughout the nation.

The comiittee, in a report released this week, also expressed the view that in recent years the promotion panel of the marshal's service "has shown a lack of racial sensitivity" to the office here.

As of last June 30, the report said, 114 of the 230 black deputy marshals in the marshals service were assigned to the D.C office. At the time there were 1,682 deputies employed throughout the nation.

The report was prepared by a committee of eight officials from various branches of the Justice Department headed by Assistant Attorney General Peter R. Taft. It stemmed from the settlement last year of a civil rights suit brough by two deputy marshals serving here.

Complaints of alleged mistreatment of blacks in the marshal's office here had been made frequently in the past and the Justice Department's own equal opportunity officers have upheld charges of bias there.

In speaking of the disciplinary proceedings against blacks, the report indicated that follow-up investigations had found a "number" of these to be unwarranted or more severe than was warranted.

It said the marshals service needs "a complete overhaul" of its EEO program.

While critical of past promotion practices, the panel noted that a new system had been set up and said it should be given an opportunity to prove itself.

On the matter of management, supervision and training in the office in these area have been and continue to be a contributing factor to the low morale and discrimination charges which continue to croup up."

It also said that because of the special responsibilities of the marshal's office here, it might be advisable to set up a separate office for D.C. Superior Court.
