GUWAHATI, Aug 1- A worldwide campaign, at the behest of Amnesty International, will be launched on November 27 to protest against the November 27, 1997, verdict of the Supreme Court granting validity to the Armed Forces (Special Powers) Act. Human rights activists the world over will wear black badges and present memoranda to the Supreme Court urging it to review its order. The call to this effect was given by human rights activists in a workshop on human rights under the aegis of Amnesty International held at Bhubaneswar in Orissa recently. The workshop, however, opposed a resolution put forward by Sumita Ghose on the issue of her husband, Sanjoy Ghose's kidnapping and subsequent death at the hands of the United Liberation Front of Asom (ULFA). The Manab Adhikar Sangram Samity (MASS) secretary general said that several programmes will also be organised in the Northeast that day to press for the revocation of the "black laws" in force in the region. It will also focus on alleged violations of human rights by law-enforcing agencies.
