A/HRC/4/41 page 25 Summary of the situation prior to the period under review 107. The majority of the 63 cases of disappearances reported in the past occurred between 1969 and 1975, under the military Government, in particular, during the period of guerrilla warfare in the Aerugo region. The majority of the cases were clarified by the Working Group in 1996 on the basis of legal provisions (Law No. 9.140/95), whereby persons who disappeared by reason of their political activities in the period 1961-1979 are considered to have died. Relatives of the victims are legally entitled to decline this legal provision or exercise the right to request death certificates. Four recent cases concern land workers in the State of Pernambuco, who disappeared on 31 May 2004 after having allegedly been arrested by police officers.
