A former Muslim cleric found guilty of marrying an underage girl to a 34-year- old man wants his conviction overturned because it was a religious marriage.

Ibrahim Omerdic, 62, appeared before the Victorian Supreme Court on Monday to appeal against a conviction that he unlawfully solemnised a marriage between the 14-year-old girl and the man at a Noble Park mosque in 2016.

Omerdic was found guilty in June in the Melbourne Magistrates' Court and sentenced to two months in prison.

But he avoided jail after he was immediately placed on a two-year recognisance release order by magistrate Phillip Goldberg.
