A government panel organized to find a new home for New York's controversial "Tilted Arc" sculpture has instead agreed with artist Richard Serra that a move would destroy its artistic value. The committee of art experts and public officials, established in 1986 by the General Services Administration, announced its opinion at its first meeting Tuesday. The 12-foot-high, 112-foot-long, rusting curve of metal was installed at a federal office building plaza in 1981. Critics say it obstructs the view and sunlight and makes gatherings in the plaza impossible. A 1985 public hearing on the issue resulted in a recommendation to remove the sculpture. And a federal judge on Aug. 31 dismissed sculptor Serra's suit claiming that moving the work would destroy its integrity and violate his constitutional rights. The GSA has not moved the sculpture.
