He was the son of Erich Andreas Thomle and his wife Mette Maria, née Binneballe.
She died shortly after, but Thomle married Juliane Marie Heyerdahl in 1845.
He held jobs in the lawyer's office of Frederik Stang and later the Ministry of Justice.
In 1879 he took the dr. juris degree at the University of Copenhagen, and that same year became the seventh Chief Justice of the Supreme Court.
