Following Germany's invasion of the Soviet Union in 1941, some Ukrainians chose to collaborate with the Wehrmacht, including Polyukhovich, one of six siblings. He was employed by a forestry department and allegedly participated in the execution of about 850 people from the Jewish ghetto in Serniki in occupied Ukraine and further executions of civilians in the same area between August and September 1942. When the Germans retreated from Ukraine, Polyukhovich and his second wife Maria left with the German troops and later Polyukhovich was given work in Germany. On 28 December 1949, Polyukhovich, his wife Maria, and two step-daughters arrived in
Melbourne, Australia. In 1958, they received Australian citizenship. On 26 December 1986, the
Adelaide Advertiser received a telex from the USSR outlining war crimes accusations against Polyukhovich. Limited examinations outside the town of Serniki of 533 selected crania confirmed that 410 of the men, women, and children exhumed had been shot in the head - see the
Sernyky massacre. Polyukhovich denied all accusations of wrongdoing. On 20 December 1988 Australia's federal parliament passed the War Crimes Amendment Bill which allows prosecutions against suspected European criminals in ordinary Australian civilian courts. On 25 January 1990 he was arrested and charged him with 24 counts of murder and complicity in 850 counts of murder. ==Legal battle==
