Crimes against humanity (including crimes related to the Holocaust) according to legislation of the USSR were classified as criminal offenses: criminal case and investigations against accused person were initiated in terms of betrayal of the Motherland. Persons involved in Holocaust-related crimes committed during the period of Nazi Germany’s occupation (1941-1945) were convicted late in World War II and after the war, mostly during 1945–1946 or later in the 1940s and 1950s. Political lawsuits about crimes against Jews were filed in early 1960s-1970s (for example, against members of 18th and 20th German Police Battalions). Fonds also includes documents about the second Soviet occupation of Latvia (1944–1990), repressed members of national resistance movement, dissidents and other persons who had committed “political crimes” against the Soviet state.

Further accruals are expected. Since this fonds is deposited in SAL, records of the fonds are supplemented with documents about deaths in GULAG camps, burials and rehabilitation of politically repressed persons which haven been received from the Russian Federation and other former Soviet republics.
