Nine members of the Solidarity underground movement went on trial. They were accused of organizing factory workers to revolt against martial law, a military-court spokesman said.
Few details were available about the defendants, who were among 21 people arrested since last December, when Polish authorities relaxed some aspects of martial law. But the Army daily Zolnierz Wolnosci said the nine were acting under the direction of Zbigniew Bujak, the former Warsaw Solidarity leader who escaped capture after the imposition of martial law in December 1981. Mr. Bujak, still at large, is considered the authorities' No. 1 target in the continuing crackdown on the banned trade union.
