Ben-Itto was appointed as a judge in Tel Aviv Magistrates' Court in 1960. In 1970 she moved to the Tel Aviv District Court. Between 1971 and 1974 she also taught criminal law at the Bar-Ilan University law school. While conducting a bank robbery trial in July 1980, she survived a bombing attack on her home, which may have been related to the trial. In 1980 she was appointed acting judge in the Israeli Supreme Court, and in 1988 became deputy president of the Tel Aviv District Court. She took early retirement from the court in 1991 in order to write her book, "The Lie That Wouldn't Die: The Protocols of the Elders of Zion".
