In the appeal, Katsav's attorneys Yehoshua Resnik and Zion Saharay claim there was a "distortion of judgment" in the Tel Aviv District Court's original ruling.
In the appeal, Katsav complained that his rape conviction was based solely on the testimony of complainant 'A' from the Tourism Ministry and was not supported by any other piece of evidence.
The former president claims phone calls he made from his car prove he was not with complainant 'A' when the rape he was convicted of took place.
The former president was convicted in 2011 of rape, sexual assault and harassment of a number of female employees while he served as tourism minister and president.
Last month Katsav, who never admitted to or expressed remorse for the offenses of which he was convicted, received his first 24-hour furlough, which he spend in his home in Kiryat Malachi. His brother Lior greeted him outside the Maasiyahu Prison in Ramla along with a small group of relatives including Katsav's son, Yisrael.
Lior told reporters that his brother is a victim of "a great injustice" and that he was "convicted of crimes that never took place."
