In his letter on the decision of Judge Frank A. Kaufman in the Prince George's County teacher desegregation case {Aug. 3}, James Turner of the Justice Department accuses The Post of inaccurate coverage, which transformed the court decision from "a clear vindication of the Justice Department's challenge into a repudiation of it." The Post was right in its story {Metro, July 20} and editorial {July 22}, and Mr. Turner is wrong.

The Prince George's County school system, like many in the nation, maintains a faculty desegregation policy in which the racial composition of the staff in each school is required to be broadly reflective of the racial composition of the staff in the system as a whole. Teachers who were involuntarily transferred so that racial balance could be maintained filed a lawsuit claiming that race-conscious policies such as Prince George's violate the 14th Amendment and Title VII of the Civil Rights Act of 1964. The Justice Department joined the teachers in their broadside attack on Prince George's faculty desegregation policy.

Judge Kaufman's July 13 decision explicitly rejected the position of the Justice Department in almost every critical respect. He held that the right to a desegregated faculty belonged to students and that the "avoidance of racially identifiable faculties is critical to a desegregation plan like that of Prince George's County, which relies heavily on magnet schools." He further stated that the "United States has failed to present any evidence" that the purposes stated for the policy were pretextual, adding that the plan did not unnecessarily trammel the interests of any teacher, and that the goal was flexibly crafted in ways which prevented infringement on promotion, salary and seniority rights.

In one respect, however, the court properly found the current application of the policy deficient, because it permitted transfers to be ordered whenever black representation at a particular school fell below 30 percent, which is the current systemwide black faculty composition. This anomaly, which occurred because of a failure of black faculty to grow as rapidly as in the past, is the one seized upon by Mr. Turner to claim "clear vindication." But it calls for only a minor modification of Prince George's faculty desegregation policy.

The fact is that Judge Kaufman upheld the policies of desegregation and diversity that the Justice Department once espoused but has long since abandoned. Mr. Turner, apparently following the tradition of King Pyrrhus, can claim victory if he likes, but the Prince George's decision was a triumph for civil rights over the current policies of the Department of Justice.
