Former Nissan Chairperson Carlos Ghosn is suing the company for more than $1 billion in a lawsuit filed with Lebanon's public prosecutor last month, according to Reuters' copy of the lawsuit.

The lawsuit filed on May 18 accuses Nissan, along with two other companies and 12 named individuals, of crimes including defamation, slander, libel and the fabrication of material evidence.

A judicial source said the prosecutor had scheduled a court session on Sept. 18 to begin proceedings.

A spokesperson for Nissan said the company would not be commenting on the matter.

Ghosn, once a titan of the global car industry, was arrested in Japan in late 2018 and charged with financial misconduct. He denied the charge and said his detention was part of a plot by Nissan executives to block a merger.

He escaped Japan hidden in a box aboard a private jet in December 2019, fleeing to Lebanon, his childhood home.

Ghosn had been awaiting trial in Japan on charges of under-reporting earnings, breach of trust and misappropriation of company funds – accusations he has repeatedly denied.

After arriving in Lebanon, Ghosn said he was escaping a "rigged" justice system in Japan and that he intended to clear his name.
