Warsaw — Solidarity, Poland's largest independent trade union, has been recognized by the Warsaw court. But in registering the union, the presiding judge inserted into the union's draft statute a pledge to respect the crucial "leading role" of the Communist Party, prompting bitter and sometimes defiant debate among the union's leaders, Monitor special correspondent Eric Bourne writes. The union's presidium condemned the court action as an "arbitrary modification . . . raising grave doubts about government goodwill," and will appeal to the high court. A full delegate meeting at Solidarity's Gdansk headquarters Oct. 27 will decide the union's response. Militant members want at least another token work stoppage, but union leader Lech Walesa and his closest aides are still thought to oppose such action "except as a last resort."
