Parents of students who were to attend Fort Hunt High School this fall will not appeal a Circuit Court judge's ruling upholding the Fairfax County School Board's decision to close the school, a lawyer said yesterday.

Judge Richard J. Jamborsky ruled last week the board did not act arbitrarily or capriciously when it voted in March to convert Fort Hunt to an intermediate school and send its students to Groveton High School in the fall. The merged high school will be renamed West Potomac. Fort Hunt will be renamed Sandburg Intermediate School.

Frank W. Dunham Jr., a lawyer for parents who had contested the School Board vote, said his clients had agreed before Jamborsky's ruling not to appeal, and he spoke with them again after the ruling to confirm their decision.

Dunham said an appeal "wouldn't serve any useful purpose. By the time an appeal would be ruled on we would be into West Potomac." The school year begins Aug. 26.

Dunham said the Fort Hunt neighborhood raised more than $10,000 to pay for transcripts and other court costs, and he estimated the actual costs would be $7,000 to $8,000. He and two others donated their time to the case; if they hadn't, Dunham estimated, the legal fees alone would have been $35,000.

The School Board closed Fort Hunt because it and other schools in the eastern county were underused due to declining enrollment. The vote drew strong neighborhood opposition, and Fort Hunt residents packed the courtroom for the 2 1/2-day trial that began July 1.
